<u>Answer:</u>
The ball fall vertically 2.69 ft by the time it reached home plate 60.0 ft away.
<u>Explanation:</u>
Fastest recorded pitches major-league baseball, thrown by nolan ryan in 1974 = 100.8 mi/hr = 44.8 m/s
The horizontal distance to home plate = 60.0 ft = 18.288 m
We have the horizontal velocity = 44.8 m/s
So time taken = 18.288/44.8 = 0.408 seconds.
The distance traveled by baseball vertically is found out by equation 
Here u =0m/s, a = 9.81
and t = 0.408 s
Substituting

So vertical distance traveled = 0.82 m = 2.69 ft
Answer:
Explanation:
From the question we are told that
The initial velocity is 
The time taken is 
The charge to mass ratio is 
Generally the acceleration is mathematically evaluated as

substituting values

The electric field is mathematical represented as

substituting values


Which is a source of AC current?
A) Generator
Math, solve fo n
0.045=n*1.6*10^-19
divide both sides by 1.6
0.028125=n*10^-19
divide both sides by 10^-19
0.028125*10^19=n
2.8125*10^17=n
B. The atom has a small dense center
