Answer:
The green car traveled a shorter distance, but the displacement of the cars was equal.
Explanation:
The total charge held in a battery is 0.
Answer:
The average power provided by the tension in the cable pulling the lift is = 714 W
Explanation:
Given data
Mass = 71 kg
Change in height = 123 m
When the lift moves in upward direction then in that case kinetic energy is constant & only potential energy changes.
Change in potential energy Δ PE = m g (
)
Δ PE = 71 × 9.81 × 123
Δ PE = 85670.73 J
Time = 2 min = 120 sec
So average power is given by



Therefore the average power provided by the tension in the cable pulling the lift is = 714 W
Answer:
34.62m/s^2
Explanation:
Force = mass x acceleration
Given
Force = 1800N
Mass = 52kg
Therefore
1800 = 52 x a
Divide both sides by 52
1800/52 = 52/52 x a
34.62 = a
a = 34.62m/s^2
Answer: There is greater genetic variety in offspring.
Explanation: This is because with asexual reproduction it is faster, but the offspring is identical to the parent. While sexual reproduction is slower yes, but there is a variety in genetics.
Hope this helps!
