Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
Simple theory.
Answer: 16N
Explanation:
According to Coulomb's law, the force existing between two charges is directly proportional to the product of their charges and inversely proportional to the distance between the charges. Mathematically,
F = kq1q2/r²
Where F is the force between them
q1 and q2 are the charges
r is the distance between them.
If the force between them is 10N, the formula becomes;
10 = kq1q2/r²... (1)
If the distance between them is now halved, the force will become
F = kq1q2/(r/2)²
F = kq1q2/(r²/4)
F = 4kq1q2/r² ... (2)
Dividing equation 1 by 2 we have;
4/F = (kq1q2/r²)÷ (4kq1q2/r²)
4/F = kq1q2/r²×r²/4k1q1q2
4/F = 1/4
Cross multiplying we have;
F = 4×4
F = 16N
Therefore the new force between the charges is 16N
Answer:
Explanation:The work done is twice as great for block B because it is moved twice the ... Equal forces are used to move blocks A and B across the floor. ... Does the normal force of the floor pushing upward on the block do any work? ... Suppose that the mass is halfway between one of the extreme points of its motion and the center point.
The correct answer is center. Hope this helps.
Answer:
A) Rapidez
Explanation:
Speed is a scalar quantity and it is found by dividing the distance traveled by the time taken.
Speed =
Distance is the length of path covered whereas time is the duration of the travel.
Unlike velocity which is a vector, speed is a scalar quantity with only magnitude but no direction.
