Answer:
human body is answer according to our studies
This question confuses me? are you asking is it difficult to walk WITH high heels?
but to answer your question, it all depends on the person. some people are naturally good at walking in heels and others could have trouble wearing them for too long, or walking normally.
Answer:
I = 7.5*10^-10 kg m/s
Explanation:
In order to calculate the impulse you first take into account the following formula:
(1)
m: mass of the pollen grain = 1.0*10^-7g = 1.0*10^-10 kg
v: final speed of the pollen grain = ?
vo: initial speed of the pollen grain = 0 m/s
Next, you calculate the final speed of the pollen grain by using the information about the acceleration and time. You use the following formula:
(2)
a: acceleration = 2.5*10^4 m/s^2
t: time = 0.30ms = 0.30*10^-3 s

Next, you replcae this value of v in the equation (1) and calculate the impulse:

The impulse delivered to the pollen grain is 7.5*10^-10 kg m/s
It means the experiment can be reproduced again and again with close results to that of the first experiment. please give brainliest?
Answer:
Power = Work / Time
P = m g h / t = 80 kg * 9.8 m/s^2 * 15 m / 39 s = 320 N m/ s = 392 J / s
= 392 Watts
