Each planet has a 'planetary body' that are pretty much always hot when they are being created. As time passes, that internal heat that causes geological activity is slowly lost. Larger planet bodies are able to keep the internal heat longer than smaller planets, and that heat is needed to keep the planets geologically active.
The only way a smaller planet can retain any heat is from tidal friction coming from another planet. The constant friction from the external body keeps that small planet from going completely cold to the core due to its size. Hope this helps!! :)
Answer:
Approximately 
(assuming that the car was on level ground.)
Explanation:
When an object of mass 
is moving at a speed of 
, the kinetic energy of that object would be 
.
Initial kinetic energy of the car:
.
After the car comes to a stop, the kinetic energy of this car would be 
because the car would not be moving.
Change to the kinetic energy of the car: 
.
If the car is traveling on level ground, friction would be the only force that contributed to this energy change. Hence:
.
The value of the work that friction did is negative. The reason is that at any instant before the car comes to a stop, friction would be exactly opposite to the direction of the movement of the car.
The work of a force on an object is the dot product of that force and the displacement of that object. The dot product of two vectors of opposite directions is negative. Hence, in this question, the work that friction did on the car would be negative because the friction vector would be opposite to the movement of the car.
Answer:
30°
Explanation:
According to the second law of reflection, it States that the angle of incidence i is equal to the angle of reflection r.
The angle of incidence is known to be the angle between the incident ray and the normal.
The Angle of reflection is the angle between the reflected ray and the normal.
This normal ray is a ray that is perpendicular to the surface.
According to the question, if the beam of light is reflected off the surface and its angle of incidence is 30°, its angle of reflection will also be 30° i.e i=r = 30°
Answer:
The primary cause of rising SST levels worldwide is climate warming due to excessive amounts of greenhouse gases being released into the atmosphere. Heat from the warming atmosphere raises the temperature of the sea surface. ... Water expands as it warms and the increased volume causes sea level rise.

I think so, sorry if wrong
