Answer: a) 8.2 * 10^-8 N or 82 nN and b) is repulsive

Explanation: To solve this problem we have to use the Coulomb force for two point charged, it is given by:

F=\frac{k*q1*q2}{d^{2}}

Replacing the dat we obtain F=82 nN.

The force is repulsive because the points charged have the same sign.

netineya [11]

Answer:

-1500 m/s2

Explanation:

So the ball velocity changes from 10m/s into the wall to -8m/s in a totally opposite direction within a time span of 0.012s. Then we can calculate the average acceleration of the ball as the change in velocity over a unit of time.

a = \frac{\Delta v}{\Delta t} = \frac{-8 - 10}{0.012} = \frac{-18}{0.012} = -1500 m/s^2

A flat screen TV uses 120 Watts. How much energy is used up if it is left on for 15 minutes? Question 25 options: 4 J 15 J 0.67
Natasha2012 [34]

Answer:

Option d (108,000 J) is the correct answer.

Explanation:

The given values are:

Power,

P = 120 Watts

Time,

t = 15 min.

i.e.,

 = 900 sec

As we know,

⇒ P=\frac{W}{t}

So,

⇒ W=P\times t

On substituting the given values, we get

⇒      =120\times 900

⇒      =108,000 \ J
