Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
The reaction which correctly represents the cellular respiration process is sugar + oxygen → carbon dioxide + water + energy.

an object is dropped from the top of a building which is 75 meters high. what's it's velocity before it reaches ground
Hi there! :)
[tex]\large\boxed{38.34 m/s}[/tex]
Use the following kinematic equation to solve:
[tex]v_{f}^{2} = v_{i}^{2} + 2ad[/tex]
Where:
vf = final velocity (?)
vi = initial velocity (0 m/s, object started at rest)
a = acceleration (gravity = 9.8 m/s)
d = distance travelled (75 m)
Plug in the given values into the equation:
[tex]v_{f}^{2} = 0^{2} + 2(9.8)(75)[/tex]
Simplify:
[tex]v_{f}^{2} = 2(9.8)(75)\\\\v_{f}^{2} = 1470[/tex]
Take the square root of both sides:
[tex]v_{f} = \sqrt{1470} = 38.34 m/s[/tex]
TRUE or FALSE? Objects in orbit around the Earth (like satellites) still have net forces acting on them.
Answer:
Objects in orbit around the Earth (like a satellite) still have net forces acting on them. True; An object with no net forces acting on it would not have a change in velocity. ... Therefore, there must be a net force acting on it.
Explanation:
Objects in orbit around the Earth (like satellites) still have net forces acting on them. This is true, because this net force make change in their motion.
What is force ?Force is an external force acting on object to change its state of motion or rest or to deform it. There are various kinds of forces such as gravitational force, magnetic force, nuclear force etc. Force is a vector quantity having both magnitude and direction.
The net force acting on a body depends on the direction and magnitude of all the forces acting on the object. The force acting on the objects that are orbiting around earth includes the gravitational force by earth, as well the force by other nearby planets or spatial objects etc.
Not all these force gets balanced and a net force always be there acting on these objects make them undergo changes in their state of motion.

Determine the number of turns of the primary winding of a transformer connected to a voltage of 380 V, if the number of turns of the secondary winding is 200 and the output voltage is 19 V.
Answer:
4000 turns
Explanation:
The formula to apply is ;
Voltage in secondary coil/ Voltage in primary coil = Turns on secondary coil/Turns in primary coil
Vs/Vp =Ns/Np
Given that;
Ns=200
Vp=380 V
Vs=19 V
Applying the formula as;

A merry-go-round with a rotational inertia of 600 kg m2 and a radius of 3.0 m is initially at rest. A 20 kg boy approaches the merry-go-round along a path tangent to the rim of the at a speed of 5.0 m/s. Determine the angular velocity of the system after the boy hops on the merry-go-round.
Answer:
The velocity of the merry-go-round after the boy hops on the merry-go-round is 1.5 m/s
Explanation:
The rotational inertia of the merry-go-round = 600 kg·m²
The radius of the merry-go-round = 3.0 m
The mass of the boy = 20 kg
The speed with which the boy approaches the merry-go-round = 5.0 m/s
[tex]F_T \cdot r = I \cdot \alpha = m \cdot r^2 \cdot \alpha[/tex]
Where;
[tex]F_T[/tex] = The tangential force
I = The rotational inertia
m = The mass
α = The angular acceleration
r = The radius of the merry-go-round
For the merry go round, we have;
[tex]I_m \cdot \alpha_m = I_m \cdot \dfrac{v_m}{r \cdot t}[/tex]
[tex]I_m[/tex] = The rotational inertia of the merry-go-round
[tex]\alpha _m[/tex] = The angular acceleration of the merry-go-round
[tex]v _m[/tex] = The linear velocity of the merry-go-round
t = The time of motion
For the boy, we have;
[tex]I_b \cdot \alpha_b = m_b \cdot r^2 \cdot \dfrac{v_b}{r \cdot t}[/tex]
Where;
[tex]I_b[/tex] = The rotational inertia of the boy
[tex]\alpha _b[/tex] = The angular acceleration of the boy
[tex]v _b[/tex] = The linear velocity of the boy
t = The time of motion
When the boy jumps on the merry-go-round, we have;
[tex]I_m \cdot \dfrac{v_m}{r \cdot t} = m_b \cdot r^2 \cdot \dfrac{v_b}{r \cdot t}[/tex]
Which gives;
[tex]v_m = \dfrac{m_b \cdot r^2 \cdot \dfrac{v_b}{r \cdot t} \cdot r \cdot t}{I_m} = \dfrac{m_b \cdot r^2 \cdot v_b}{I_m}[/tex]
From which we have;
[tex]v_m = \dfrac{20 \times 3^2 \times 5}{600} = 1.5[/tex]
The velocity of the merry-go-round, [tex]v_m[/tex], after the boy hops on the merry-go-round = 1.5 m/s.

A toy plane with a mass of 20 kg is flying at 10 m/s. What is its kinetic energy?
A. 1 000 J
B. 200 J
C. 2 000 J
D. Cannot be determined
Answer:
[tex]\boxed {\boxed {\sf A. \ 1000 \ Joules}}[/tex]
Explanation:
Kinetic energy can be found using the following formula.
[tex]E_k=\frac{1}{2}mv^2[/tex]
where m is the mass and v is the velocity.
The mass of the toy plane is 20 kilograms and the velocity is 10 meters per second.
[tex]m= 20 \ kg \\v= 10 \ m/s \\[/tex]
Substitute the values into the formula.
[tex]E_k=\frac{1}{2}(20 \ kg) (10 \ m/s)^2[/tex]
Solve the exponent first.
(10 m/s)²= 10 m/s *10 m/s= 100 m²/s²[tex]E_k=\frac{1}{2} (20 \ kg) (100 \ m^2/s^2)[/tex]
Multiply the last two numbers together.
[tex]E_k= \frac{1}{2}(2000 \ kg*m^2/s^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]E_k= 1000 \ kg*m^2/s^2[/tex]
1 kilogram square meter per square second is equal to 1 Joule. Our answer of 1000 kg*m²/s² is equal to 1000 Joules[tex]E_k= 1000 \ J[/tex]
The kinetic energy of the toy plane is 1000 Joules

A car's engine provides a driving force of 30N. The car travels at a steady speed of 20m/s. What is the size of the resistive force acting against the driving force?
Answer:
30 N
Explanation:
Since the car travels at a steady speed of 20m/s and has a driving force of 30N, there is no net acceleration and thus, the resistive force is also 30 N in magnitude but in the opposite direction to the driving force. This is shown below.
F - f = f' where F = driving force = 30 N. f = resistive force and f'= net force.
f' = 0 since there is no acceleration. So,
F - f = 0
F = f = 30 N
The right answer is "30 N"
Answer explanation:
If a car is travelling at a steady speed, the resultant force must be zero, so the driving force and resistive force must be equal and opposite.

how can being near a large body of water affect the climate of the region?
Answer:
yes
Explanation:
If you've ever heard of lake effect snow that is when cold air mass moves across long expanses of warmer lake water. The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above; the vapor then freezes and is deposited on the leeward (downwind) shore. this is most common with lake Michigan when cold air travels down from Canada making the neighboring states colder, so YES, being near any body of water can effect the climate.

a bulge of water in the ocean known
as a storm surge (stawrm surj). As
a storm moves over a coast, the
storm surge can cause water levels to
suddenly rise, or surge, several meters.
The main dangers in a hurricane

flooding. If possible, leave areas
threatened by a hurricane. Take
prescription medicines with you.
If you stay in a building, board up

Describe reflection using the terms incident ray and reflected ray.
10 points fast
10 POINTS ASAP
Answer:
The normal line divides the angle between the incident ray and the reflected ray into two equal angles. ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection
The law of reflection is the idea that when light rays strike a smooth surface, the angle of incidence and the angle of reflection are both identical. Additionally, the incident ray, the reflected ray, and the surface normal all reside in the same plane.
What is reflection?Reflection of light refers to the act of light rays hitting a surface and reflecting back.
According to the law of reflection, the angle of the reflected ray, when reflecting from a smooth surface, is equal to the angle of the incident ray, with regard to the surface's normal, which is a line perpendicular to the surface at the point of contact.At the point of contact of the incident ray, the reflected ray is always in the plane defined by the incident ray and the normal to the surface.The law of reflection explains how both curved and planar mirrors form images.
