the force of attraction between the sun and earth is called ___
Answer: The force of attraction between the sun and earth is called gravity
Explanation:
Gravity is the force of attraction between two objects that is proportional to their masses and the distance between them. It is the force that keeps the Earth and other celestial bodies in orbit around the Sun, and it is also responsible for holding the Moon in orbit around the Earth. Newton's law of universal gravitation states that the force of gravity between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the larger the masses of two objects and the closer they are to each other, the stronger the force of gravity between them will be. The force of gravity is a fundamental force in the universe, and it plays a crucial role in shaping the motion and structure of celestial bodies.
Answer:
Universal Gravitation
Explanation:
The gravitational force of attraction between Earth and the sun is 1.6 1023 N

all activities begin in which energy pathway?
Answer: Phosphagen Pathway
Explanation:
is the first energy source called upon at the beginning of any exercise program or in burst movements that are too quick for other systems to be called into action
The All activities in the human body begin with the energy pathway known as cellular respiration.
Cellular respiration is the process by which cells convert the energy stored in food molecules, such as glucose, into a form that can be used by the body. This process takes place in the mitochondria, the powerhouses of the cell. There are two main stages of cellular respiration: glycolysis and the citric acid cycle.
Glycolysis is the breakdown of glucose into two pyruvate molecules and the generation of a small amount of ATP. This stage takes place in the cytoplasm and does not require oxygen.
The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid cycle, takes place in the mitochondria and generates a large amount of ATP. During this cycle, the pyruvate molecules produced in glycolysis are converted into acetyl-CoA, which enters the citric acid cycle. The citric acid cycle produces high-energy electrons, which are used to generate ATP through oxidative phosphorylation.
The final stage of cellular respiration is the electron transport chain, which takes place in the inner membrane of the mitochondria. In this stage, the high-energy electrons produced in the citric acid cycle are transferred along a series of proteins, generating a proton gradient that drives the production of ATP.
In summary, cellular respiration is a complex and essential process that allows cells to generate the energy needed for all their activities, from muscle contractions to brain function.

define equilibrium ?
Equilibrium refers to a state in which the forces acting on an object are balanced and there is no net force acting on it. This means that the object is either at rest or moving at a constant velocity, and its motion will not change unless acted upon by an external force. In other words, in a state of equilibrium, the sum of all the forces acting on an object is equal to zero. This concept is a fundamental principle in physics, and it is related to the laws of motion and the conservation of energy.

The capacitance is unchanged, and the potential difference between the plates is halved. So the correct option is 1 and 4.
When the plate separation is doubled while the battery remains connected, the electric field between the plates decreases and the potential difference between the plates is halved. The electric charge on the plates remains unchanged, as the electric field is proportional to the electric charge and the capacitance. The decrease in the potential difference between the plates also results in a decrease in the capacitance.
The formula for the capacitance of a parallel plate capacitor is given by C = ε0A/d, where ε0 is the permittivity of free space, A is the surface area of the plates, and d is the distance between the plates. When the plate separation is doubled, the capacitance of the capacitor decreases by a factor of four, as C = ε0A/(2d) = ε0A/d / 2. This decrease in the capacitance is due to the increased distance between the plates and the decreased electric field between the plates.

A particle travels to the right along a straight line with a velocity v=[5/(4+s)] m/s where s is in meters. Determine its position when if when t = 6 s if s = 5 m t = 0.
The position of the particle when t = 6 s if s = 5 m, t = 0 is calculated to be 9.58 m.
We know that the position is the anti-derivative of velocity. So, to find the expression of the position at time t, we integrate the velocity:
s(t) = ∫ v(t) dt
s(t) = ∫ (5/(4+t)) dt
s(t) = 5 ∫ (1/(4+t)) dt
s(t) = 5 ln(4 + t) + c
We use the beginning condition that s = 5 m when t = 0 to solve for the integration constant c.
s(0) = 5 ln (4+0) + c
5 = 5 ln (4) + c
c = 5 - 5 ln (4) = 1.93
So the displacement expression is,
s(t) = 5 ln (4+t) - 1.93
Thus, when t = 6s, the position is
s(6) = 5 ln (4+6) - 1.93 = 9.58 m

final speed = total momentum / total mass = 30.0 kg*m/s / 6.0 kg = 5.0 m/s.
define speed ?
Speed is a scalar quantity that represents the rate of change of an object's position with respect to time. It is defined as the distance traveled by an object divided by the time taken to travel that distance. It has units of meters per second (m/s) or miles per hour (mph) and is a measure of the velocity of an object.
The final speed of the two carts after the collision can be found using the law of conservation of momentum. The law states that the total momentum of a system remains constant if there are no external forces acting on it.
The initial momentum of the first cart is 4.0 kg * 6 m/s = 24.0 kgm/s. The initial momentum of the second cart is 2.0 kg * 3 m/s = 6.0 kgm/s. The total initial momentum is 24.0 kgm/s + 6.0 kgm/s = 30.0 kg*m/s.
After the collision, the carts stick together and move as a single object with mass 4.0 kg + 2.0 kg = 6.0 kg. The final speed of the combined carts is given by:

The given information provides some of the variables needed to calculate the magnitude of the basketball's initial velocity and its velocity when it passes through the basket. To solve for these velocities, we will use the equations of motion for a projectile under constant gravitational acceleration.
The magnitude of the initial velocity (VA) can be found using the equation:
VA = √((Vg^2) + (Ug^2) + 2 * a * h)
where Vg is the final velocity, Ug is the vertical component of the initial velocity, a is the acceleration due to gravity (9.8 m/s^2), and h is the vertical height of the ball's trajectory.
We know the final velocity (Vg) from the given information: Vg = 10.8 m/s.
The vertical component of the initial velocity (Ug) can be found using the equation:
Ug = Vg * sin(Θ)
where Θ is the angle of the trajectory.
We have the angle of the trajectory (Θ) from the given information: Θ = -20.7°.
Now that we have all the variables, we can substitute them into the first equation to find the magnitude of the initial velocity (VA).
The velocity of the ball when it passes through the basket (Vb) can be found using the equation:
Vb = √((VA^2) + 2 * a * (h - d))
where d is the distance from the basket to the ground.
We have the distance from the basket to the ground (d) from the given information: d = -10 m.
Now that we have all the variables, we can substitute them into the second equation to find the velocity of the ball when it passes through the basket (Vb).
In conclusion, by using the equations of motion for a projectile under constant gravitational acceleration, we were able to determine the magnitude of the basketball's initial velocity and its velocity when it passes through the basket.

High energy, short wavelength electromagnetic radiation is what X-rays are. Since their discovery in 1895 by Wilhelm Conrad Roentgen, they have been applied in numerous fields, such as cancer treatment and medical imaging. X-rays are used in medical imaging to create images of the internal anatomy of the body, including the bones and organs, to aid in the diagnosis of illnesses and injuries. X-rays are used to cure cancer by destroying cancerous cells and reducing tumour size. X-rays can also penetrate a wide range of materials, which makes them valuable in a number of other industries like industrial inspection and security scanning. However, prolonged exposure to X-rays can be hazardous, cause tissue damage, and raise the risk of developing cancer.

Which one of the following statements about rate constant k is false?A) k is dependent on concentration of the reactants.B) k increases with increasing temperature.C) k decreases with increasing activation energy.D) k can be increased by adding a catalyst.E) k is directly proportional to the rate of a reaction.
C) k decreases with increasing activation energy.
C) k decreases with increasing activation energy
A) Reactant concentration affects k: As the concentration of the reactants rises, the frequency of the reactant molecules colliding likewise rises, increasing the pace of the reaction and, consequently, k.
B) As temperature rises, the kinetic energy of the reactant molecules increases. This leads in more frequent and energetic collisions, which raises the rate of reaction and increases k.
D) The addition of a catalyst can raise the value of k because it speeds up the rate of reaction by offering a different reaction pathway with a lower activation energy.
E) The unit k measures the rate of a reaction and is directly proportional to it.

What people sometimes call "moonlight" is actually sunlight reflecting off the moon's surface. The moon itself doesn't give off any light at all. But the moon can sometimes look blue, orange or even red depending on the particles (like dust or pollution) in the atmosphere and the moon's location in the sky.
It takes approximately one month for the moon to travel around the Earth. Because of the moon's movement around the Earth and the reflected light from the sun, we see different portions of the moon's lit half at different times.
A month of lunar phases
While out camping one spring night, you think the moon looks orange. What is one possible explanation?
answer choices
O The moon is in its orange phase.
O The sun is orange, and the moon is reflecting its reddish light.
O The moon itself is giving off an orange light.
O The dust in the atmosphere makes the moon appear orange.
While out camping one spring night, you think the moon appears to be orange. The one possible explanation is D: "the dust in the atmosphere makes the moon appear orange".
The reason the moon appears orange during a camping trip is because of dust in the atmosphere. The moon reflects sunlight, and the light from the sun that reaches the moon is white. However, the light from the moon that reaches the observer on Earth can change color depending on the particles in the Earth's atmosphere.
Dust, smoke, and pollution in the air can scatter the light in different directions, causing the light to appear orange. The color of the moon is not due to the moon itself giving off light (as it doesn't emit light), or the sun being orange, or a special "orange phase" of the moon. The color of the moon can also sometimes appear red or yellow, and this too is due to the particles in the atmosphere scattering light in different ways.

lace a hollow conductor between the charged plates and measure the electric potential at several points inside the conductor. based on your measurements, what can you conclude about the electric field inside the hollow conductor?
Based on measurements, it can be concluded that the electric field inside the hollow conductor is zero, because the fact that the electric field inside a hollow conductor must be zero if it is a perfect conductor.
At the point when you place an hollow conduit between charged plates and measure the electric potential at various focuses inside the transmitter, you can decide the strength of the electric field inside. Assuming the electric potential stays a similar regardless of where you measure it, this implies that the electric field inside the channel is zero. This is on the grounds that an ideal channel, similar to an hollow metal circle, permits no electric charge to course through it.
Furthermore, in the event that there were an electric field inside the conveyor, this would make electric charges move, which would bring about an electric flow. Yet, as an ideal conveyor doesn't permit electric flows, it should have a zero electric field inside. This implies that the electric potential estimations support the end that there's no electric field inside the hollow conduit.

a tank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes
The line tangent to the curve has an estimated slope of - 33.2 the line tangent to the curve has an estimated slope of - 33.2 gallons per minute. per minute.
How to calculate a tangent line's slope by averaging two nearby secant lines
Using the table's data and the secant line formula, we must infer the slope of a number of lines in this problem:
m = [f(q)-f(p)] / (q-p) (1)
The slope of the secant lines is given by: Use the slope formula for the two points on each secant line. (15, 250) and (5, 694): m = (694 – 250) / (5 – 15) = −44.4
(15, 250) and (10, 444): m = (444 – 250) / (10 – 15) = −38.8
(15, 250) and (20, 111): m = (111 – 250)/ (20 – 15) = −27.8
(15, 250) and (25, 28): m = (28 – 250)/ (25 – 15) = −22.2
(15, 250) and (30, 0): m = (0 – 250) / (30 − 15) ≈ −16.7
The equations for the secant lines are obtained by using the point-slope formula.
V − 250 = −44.4(t − 15)
V − 250 = −38.8(t − 15)
V − 250 = −27.8(t − 15)
V − 250 = −22.2(t − 15)
V − 250 ≈ −16.7(t − 15)
Part (b) Use the slopes of the secant lines going through the points closest to (15, 250), (10, 444) and (20, 111), to get the most accurate slope of the tangent line.
M tangent = −38.8 + (−27.8) 2 = −33.3
The slope of the tangent line at t = 15 is about −33.2825, which is consistent with the result in part (b). dV dt ≈ −66.7897 + 2(1.12190) t − 3(0.000222222) t 2 dV dt
t=15 ≈ −66.7897 + 2(1.12190) (15) − 3(0.000222222) (15)2 ≈ −33.2825
At the coordinates (x, y) = (15, 765), the line tangent to the curve has an estimated slope of - 33.2 gallons per minute.

A precondition for motion pictures was that scientists had to realize that the human eye will perceive motion if presented with a rapid succession of still images.
The human eye is a complex and delicate organ responsible for the sense of sight. It is composed of various structures, including the cornea, lens, retina, and optic nerve, which work together to process and transmit visual information to the brain. Light enters the eye through the cornea and passes through the lens, which focuses the light onto the retina. The retina contains photoreceptor cells called rods and cones, which detect light and convert it into electrical signals. These signals are then transmitted via the optic nerve to the brain, where they are processed into the images we see. The eye is capable of adjusting the amount of light it allows in and can change focus to enable us to see objects at different distances. The human eye is an remarkable and essential part of our sensory system.

What is the synodic or sidereal period?The sidereal orbital period of the Moon, also known as the sidereal month, is 27.3 days. During this time, the Moon revolves 360° about the Earth in relation to the "fixed" stars. The duration of the lunar phases (the synodic month), such as the time between full moons, is longer and lasts for around 29.5 days. Due to the fact that the moon and Sun are travelling in tandem around the Sun, the orbital period, which is 27.32 days, is not the same as the synodic period, or the time between consecutive full moons or successive new moons, which is 29.53 days.
