Answer:
10N
Explanation:
Given data
Work done = 200J
distance= 20m
We want to find the applied force
From
Work done= Force * distance
substitute
200= F*20
F= 200/20
F= 10N
Hence the force applied is 10N

Answer:
<h3>its c(Norfolk is less humid and has higher precipitation than San Francisco</h3>
Explanation:
We will first convert all units to meters and then solve the problem.
We are given that:
1000 mm = 1 m
120 mm = ?? meters
using cross multiplication:
120 mm = (120*1) / 1000 = 0.12 m
Now, when the two objects are placed over each other, their total height is the result of summation of both heights, therefore:
total height = 0.12 + 1.5 = 1.62 m
Based on the above calculations, the correct choice is:
<span>b) 1.62 m </span>
I believe it’s A, i could be wrong tho 3
