Answer:
Explanation:
Work done = force x displacement
force = mass x acceleration (due to gravity)
work done =25 * 9.8 * 3 = 735J
Answer:
735 J
Explanation:
F (force) = ma = mg = 25kg × 9.81m/s² = 245.25N.
we are lifting, so the acceleration is going against Earth's gravity.
the work done to lift it up by 3 m is then
W = F×d = 245.25N×3 m = 735.75 J
the time (2 seconds) does not play a role here.
it would be needed to calculate the power needed to lift 25kg 3 m in 2 seconds :
power = W/t = 735.75/2 = 367.875 watts
a 10,000 gallon water tank atop a building delivers fresh drinking water for its occupants. the top floor resident and the bottom floor resident are filling their bathtubs. assuming frictionless pipes and isothermal flow, which one will fill faster?
The bathtub on the bottom floor will fill faster assuming frictionless pipes and isothermal flow.
In an isothermal flow, the temperature remains constant and the pressure decreases as the height increases. This means that the pressure at the bottom floor is higher than the pressure at the top floor. As a result, the water will flow more quickly through the pipes to the bottom floor, filling the bathtub there faster.
This can be understood by considering the relationship between pressure and flow rate in a pipe: flow rate is proportional to the pressure difference. In this case, the pressure difference between the top and bottom floors is driving the flow of water, so the bathtub on the bottom floor will fill faster.

Explanation:
I would recommend watching TV shows like "How the Universe works" or "Space's deepest Secrets".
so, if there were no gravity ?
no bigger bodies or structures would have formed at all. the universe would be one big "sea" of hydrogen atoms (and some helium and very few other atoms, whatever the Big Bang created by itself - depending on what the Big Bang really was, and if there really was such a thing) floating through the ever expanding spacetime.
yes, some tiny structures would have formed via electrostatic forces, and also via chemical reactions forming some larger molecules of atoms driven just by chance and the coincidence that atoms would even get that close to each other. but not many, as the larger atoms (like oxygen) can only be created by fusion of smaller atoms, which can only happen with immense pressure, which can only happen by gravity squeezing atoms together in cores of stars and such.
in other words, no black holes, no Galaxies around them, no stars in them, no planets and moons, no asteroids and comets around them would have formed.
the universe would be dark from the very beginning, just glimmering with the leftover background radiation from the Big Bang (or whatever it was).
there would be actually nothing to observe, literally.
a net force of 11.4 n is applied to the left on a 12.3-kg object. the object goes from a horizontal location of 9.2 m to a horizontal location of -10.1 m. what is the work done by the net force?
The work done by the net force is equal to the force multiplied by the displacement. In this case, the force is 11.4 N and the displacement is 19.3 m (9.2 m - (-10.1 m)).
Therefore, the work done by the net force is 11.4 N × 19.3 m = 218.62 Nm.
To further explore this topic, it is important to understand the concepts of work, force, and energy.

what was the most important difference in development between isaac newton's theory of planetary motion and that of johannes kepler?
The most important difference in development between Isaac Newton's theory of planetary motion and that of Johannes Kepler was the explanation of why planets move in the way that they do.
Kepler's laws of planetary motion were based on extensive observations of the positions of the planets in the sky, and he discovered that planets move in elliptical orbits around the sun, with the sun located at one of the foci of the ellipse.
Isaac Newton, on the other hand, was able to provide a physical explanation for why planets move in elliptical orbits around the sun. Newton's law of universal gravitation stated that all objects in the universe are attracted to each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Using this law, Newton was able to demonstrate that the gravitational attraction between a planet and the sun causes the planet to move in an elliptical orbit.

if the speed of the block is 5.00 m/s when it reaches the bottom of the ramp, what was the work done on it by the friction force?
The work done on an object by a force is given by the product of the force and the distance over which it acts.
In this case, the work done on the block by the friction force is equal to the friction force multiplied by the distance over which it acts.
Assuming that the block started from rest at the top of the ramp, its initial potential energy was converted to kinetic energy as it slid down the ramp. At the bottom of the ramp, the kinetic energy of the block is given by 1/2 mv^2, where m is the mass of the block and v is its speed. Since there is no potential energy at the bottom of the ramp, the work done by all the forces acting on the block must be equal to the initial potential energy.Therefore, the work done on the block by the friction force is equal to the initial potential energy minus the kinetic energy at the bottom of the ramp. The initial potential energy is given by mgh, where m is the mass of the block, g is the acceleration due to gravity, and h is the height of the ramp.Without knowing the values of m and h, we cannot calculate the exact work done on the block by the friction force.

In physics, mass isn't the same as weight, even though mass is regularly determined by means of measuring the object's weight with the use of a spring scale, in place of a stability scale comparing it without delay with known hundreds. An item on the Moon could weigh much less than it does on this planet due to the decrease in gravity, but it'd nevertheless have the same mass.

When we see the brightest star in the constellation Orion just rising above your eastern horizon at 10 pm and One week later at 10 PM this same star will be at its highest point in the sky, directly overhead .
The position of Stars in the sky changes as the Earth rotates on its axis.
As the Earth rotates, different stars appear to rise in the east and set in the west.
If we see the brightest star in constellation Orion just rising above our eastern horizon at 10 PM, and 1 week later at 10 PM, this same star will be at its highest point in the sky, directly overhead.
This is because the Earth has rotated 1 full revolution in a week, which causes the star to move from the eastern horizon to the overhead position.

why is the current across a drain resistor the same as the current across drain to source in a mosfet
The current across a drain resistor is the same as the current across the drain to source in a MOSFET because the MOSFET behaves as a voltage-controlled resistor.
What is resistor ?A resistor is an electrical component that is used to reduce the flow of current in an electrical circuit. It works by creating electrical resistance, which is measured in ohms. This resistance opposes the flow of current, allowing engineers to control the voltage and current levels in a circuit. Resistors are used in many different types of applications, from controlling the speed of motors to regulating the flow of current in digital circuits.
The resistance of the MOSFET channel is controlled by the voltage applied to the gate. If the gate voltage is increased, the resistance of the channel decreases, allowing more current to flow from the drain to the source. Since the drain resistor is in series with the MOSFET channel, the same current must also flow through the resistor.

a small car of mass mand a large car of mass 4mdrive along a highway at constant speed. they approach a curve of radius r. both cars maintain the same acceleration aas they travel around the curve. how does the speed of the small car vscompare to the speed of the large car vlas they round the curve?
The speed of the small car and the large car will be the same as they round the curve.
As both cars are experiencing the same acceleration a and are traveling along the same curve with radius r, their speeds will be determined by the same centripetal acceleration equation: a = v^2 / r. This means that the speeds of the two cars, v_s and v_l, will be proportional to the square roots of their masses. Therefore, v_s / v_l = sqrt(m / (4m)) = sqrt(1 / 4) = 1 / 2. So, while the large car has four times the mass of the small car, they will still be traveling at the same speed as they round the curve.
