Answer:
See explanation
Explanation:
The centripetal force keeps an object moving in a circular orbit at constant velocity. The velocity of an object undergoing uniform motion is always tangential to the circle while the centripetal force is directed towards the center of the circle.
This now implies that the direction of the force acting on a body undergoing circular motion at constant velocity is perpendicular to the direction in which the object is being displaced.
1.44Ns
6.3m/s
Explanation:
Given parameters:
Mass of object = 230g = 0.23g
height of fall = 2m
Unknown:
Impulse = ?
velocity on impact = ?
Solution:
We are going to apply one of the equations of motions to solve this problem.
The most appropriate one is:
V² = U² + 2gH
where V is the final velocity
U is the initial velocity
g is acceleration due to gravity as the body falls with aid of gravity = 9.8m/s²
H is the height of fall
since the body was initially at rest, U = O
V² = 2gH
V = √2 x 9.8 x 2 = 6.3m/s
Impulse = mass x velocity = 0.23 x 6.3 = 1.44Ns

Answer:
Planet Z will have the following properties;
Active Volcanoes
Active Tectonics
An Atmosphere produced by outgassing
Explanation:
The little terrestrial worlds have heat shorter than the much bigger terrestrial worlds, so the bigger worlds tend to have active volcanism and tectonics. These active volcanism and tectonics are likely to erase ancient craters. The active volcanism and tectonics would create an atmosphere by producing gases.
It is know that the Terrestrial worlds that are not far from the star have higher surface temperature.
Fast rate of rotation can cause winds and strong storms but here it is slower compared to earth. Also, a tilt of axis causes seasons.
The properties the star have are active volcanoes, active tectonics and an atmosphere produced by outgassing.
