A baseball pitcher throws a fastball with a 100 ns impulse. if he applied the force in 0. 15 seconds, what force did he apply?

Physics

Answer:

The force he will apply is 666.667 N

Explanation:

The impulse is given as the product of Force and time:

              Impulse (I) = F * t

As we are provided with the impulse and that is:

I = 100 ns and t = 0.15 s

So, required force is:

                 F = I/t

                 F = 100/0.15

                 F = 666.6667 N

Which scenario describes the damage caused by a tornado?
9966 [12]

The answer is a path of destruction up to 50 miles long with destroyed trees and homes.

Tornadoes form from severe thunderstorms. Wind in the higher altitude of the storm moving at a greater velocity than wind at a lower altitude creates a vertical wind shear. The faster-moving winds aloft come from the west and create an updraft when they meet slower-moving wind close to the ground that is moving in the opposite direction. As warm surface air moves upward into the thundercloud, the rotating air creates a vortex.

The image below shows before and after damage of a tornado.

If 1.34 ✕ 1020 electrons move through a pocket calculator during a full day's operation, how many coulombs of charge moved throu
ioda

Given :

Number of operations move through a pocket calculator during a full day's operation , n=1.34 \times 10^{20} .

To Find :

How many coulombs of charge moved through it .

Solution :

We know , charge in  one electron is :

e^-=-1.6\times 10^{-19}\ coulombs

So , charge on n electron is :

C=e^-\times n\\C=-1.6\times 10^{-19}\times 1.34\times 10^{20} \ C\\C=-21.44\ C

Therefore , -21.44 coulombs of charge is moved through it .

Hence , this is the required solution .
