Answer:

A)  

Each hair was induced with a positive charge. Each hair repels against its neighbor and stands up.

Explanation:

When we touch the Van-de-Graff generator then due to high potential of the generator the charge is induced in our hairs.

Due to induction of charge in hairs all the hairs get similar charge and this similar charge is on each hair is along its whole length.

Now due to coulombs law all hairs are repelling each other due to similar nature of charge and this repulsion against each neighboring hair will stand the hairs upwards

so correct answer will be

A)  

Each hair was induced with a positive charge. Each hair repels against its neighbor and stands up.

A runner of mass 51.8 kg starts from rest and accelerates with a constant acceleration of 1.31 m/s^2 until she reaches a velocit
Stells [14]

Answer:32.24 s

Explanation:

Given

mass of runner (m)=51.8 kg

Constant acceleration(a)=1.31 m/s^2

Final velocity (v)=5.47 m/s

Time taken taken to reach 5.47 m/s

v=u+at

5.47=0+1.31\times t

t=\frac{5.47}{1.31}=4.17 s

Distance traveled during this time is

s=ut+\frac{1}{2}at^2

s=\frac{1}{2}\times 1.31\times 4.17^2=11.42 m

So remaining distance left to travel with constant velocity=153.57 m

thus time =\frac{distance}{speed}

t_2=\frac{153.57}{5.47}=28.07 s

Total time=28.07+4.17=32.24 s
