Answer:
The force is calculated as 338.66 N
Explanation:
We know that force is given by
We know that range of a projectile is given by
it is given that R=130 m applying values in the above equation we get
Thus the force is obtained as
Thus force equals 
Answer:
I = 12 A
Explanation:
For this exercise we use the relationship that voltage is proportional to the product of current and resistance
V = I R
I = V / R
let's calculate
I = 120/10
I = 12 A
