Answer:
0.0366 m
Explanation:
We are given;
Current density; J = 540 A/cm² = 540 × 10⁴ m
Current; I = 0.57 A
Now, formula for current density is;
J = I/A
Where A is area = πr²
Thus;
J = I/(πr²)
r = √(I/(Jπ))
r = √(0.57/(540π))
r = 0.0183 m
Diameter = 2 × radius
Diameter = 2 × 0.0183
Diameter = 0.0366 m

The answer is, "B", "Ammonia".
The acceleration of the baseball is:

where

and

are the final and initial speed of the ball, and

is the time interval in which the force acted.
Replacing the numbers, we get

And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
Compression is a type of force, like when you crush a soda can, your compressing it.
