Erosion is mainly caused by water, wind, and gravity.
Answer:
Explanation:
Recall that in this case, friction is not taken into account. Thus, Using the free body diagram, according to Newton's second law, we have:
For the lighter block:
For the heavier block:
The acceleration is the same for both blocks:
So, replacing (2) in (1):
Answer:
- Newton's first law applies. An object at rest will stay that way until a force is applied.
- Any amount of effort can be applied to any amount of mass (in the ideal case). The question is not sufficiently specific.
Explanation:
A force is required to move an object because the object will stay at rest until a force is applied.
__
The effort required to lift or push two masses instead of one depends on the desired effect. For the same kinetic energy, no more effort is required. For the same momentum, half the effort is required for two masses. For the same velocity, double the effort is required.

Answer:
Explanation:
Given that
L = 3 m
M = 2.4 kg
m=0.7 kg
r= L/2 = 1.5 m
The moment of inertia of rod about it center
The moment of inertia of point mass about center of rod
I'= mr² + mr²
So total moment of inertia
By putting the values
