Without wind, many of the trees and plants you see today would not be there. The wind blows seeds through the air, like wish flowers. Also, some electricity wouldn't work because some people's electricity comes from wind turbines. Wind turbines are generated by wind :)
Answer:
C
Explanation:
Force is a vector quantity. So, it has magnitude and direction which can also be describe as strength and direction
It's too much I don't understand.sorry
Answer:
Explanation:
Given that,
g = 31 ft/s²
For every 1 lbf force, the compression is 1in
Then we can know the spring constant.
From Hooke's Law
F = Kx
K = F/x
K = 1/0.14
K = 7.143 lbf/in
Now, if the spring deflection is 1.8in
Then, the force applied is
F = kx
F = 7.143 × 1.8
F = 12.857 lbf
Now, this force is equal to the weight of the body
And weight of the body can be determined using.
W = mg
Therefore,
m = W/g
m = 12.857 / 31
m = 0.415 lb
The mass of the object is 0.415 pounds
