The answer is B, as more lights are added to the circuit the voltage to each decreases
Answer:
a. Potential energy of the sled is increased when height of sled is increased.
b. Potential energy of the sled is increased when height of sled is increased.
c. P.E₂₀ = 2 P.E₁₀
d. P.E₂₀₀ = 2 P.E₁₀₀
Explanation:
The potential energy of the sled can be given by the following:
where,
m = mass of sled
g = acceleration due to gravity
h = height of sled
a.
It is clear from the formula that potential energy of sled is directly proportional to the height of sled.
<u>Therefore, potential energy of the sled is increased when height of sled is increased.</u>
b.
It is clear from the formula that potential energy of sled is directly proportional to the mass of sled.
<u>Therefore, potential energy of the sled is increased when mass of sled is increased.</u>
<u></u>
c.
<u>P.E₂₀ = 2 P.E₁₀</u>
<u></u>
d.
<u>P.E₂₀₀ = 2 P.E₁₀₀</u>
