Answer:
I don't really understand the wording of this question but I'd totally cuddle a Koala! If they weren't so mean
Explanation:
Thanks for listening!
Explanation:
a. The net force is the upward force of the chute minus the weight of the crate.
∑F = F − mg
∑F = 150 N − (11 kg) (9.8 m/s²)
∑F = 42.2 N
b. From Newton's second law, the net force equals the mass times acceleration:
∑F = ma
42.2 N = (11 kg) a
a = 3.84 m/s²
c. Acceleration is the change in velocity over change in time. Assuming the crate is released from rest:
v = at + v₀
v = (3.84 m/s²) (5 s) + (0 m/s)
v = 19.2 m/s
Answer:
The change in gravitational potential energy of the climber-Earth system,
Explanation:
Given that,
Mass of the hiker, m = 85 kg
Time, t = 2 h
Vertical elevation of the climber, h = 540 m
We need to find the change in gravitational potential energy of the climber-Earth system. We know that due to change in position of an object, gravitational potential energy occurs. It is given by :
So, the change in gravitational potential energy of the climber-Earth system is 
. Hence, this is the required solution.
B. for growing vegetation and crops, because it says that, "The newly deposited soil nutrient rich and would be good." so it's good for the crops.
That Usually depends. Like if water is from the Alantic Ocean and the water is from the Pacific Ocean. But it would depend on where water comes from. It would also depend on what temperature the water is in
