Answer:
Because Moon and Mars has no atmosphere.
Explanation:
Moon and Mars has no atmosphere, so there is no friction on the falling object due to the atmosphere. The speed of the falling object is more at Moon and Mars.
When a small object impact on the surface of moon or Mars with high speed, the size of crater is large than the earth as out earth has atmosphere.
The formula we can use in
this case would be:
v = sqrt (T / (m / l))
Where,
v = is the velocity of the
transverse wave = unknown (?)
T = is the tension on the
rope = 500 N
m = is the mass of the
rope = 60.0 g = 0.06 kg
l = is the
length of the rope = 2.00 m
Substituting the given values into the equation to search
for the speed v:
v = sqrt (500 N/(0.06 kg /2 m))
v = sqrt (500 * 2 / 0.06)
v = sqrt (16,666.67)
<span>v = 129.10 m/s</span>
Answer:
An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.
