Answer:
Stays the same.
Explanation:
The temperature does not change just because something melts.
The acceleration due to gravity near the surface of the planet is 27.38 m/s².
<h3>
Acceleration due to gravity near the surface of the planet</h3>
g = GM/R²
where;
- G is universal gravitation constant
- M is mass of the planet
- R is radius of the planet
- g is acceleration due to gravity = ?
g = (6.626 x 10⁻¹¹ x 2.81 x 5.97 x 10²⁴) / (6371 x 10³)²
g = 27.38 m/s²
Thus, the acceleration due to gravity near the surface of the planet is 27.38 m/s².

Answer:
B.
The light waves are completely blocked.
Explanation:
The intensity of the light coming out after two polarizers is given by Malus' Law:
where
is the initial intensity of light before the polarizers
is the intensity of light after the two polarizers
is the angle between the axes of the two polarizers
In this problem, we have two polarizers with their axes placed perpendicular to each other: this means that the angle is 90 degrees
Therefore, the cosine factor is zero:
And this means that the intensity of light after the two polarizers is also zero:
So, the correct option is
B. The light waves are completely blocked.
Newton's first law of motion states that an object at rest stays at rest unless acted upon by a force while an object at motion stays in motion unless acted upon by an opposite force. Therefore, the ball in motion will stay at motion considering there is no friction force in the field, answer is A. If the field has friction force against the ball then it will slow down and stop eventually, answer is B.
