Answer:
b,c,a.
Explanation:
We know that mass of sun > mass of Earth> mass of mars>mass of mars.
And Gravitation force F =
G= gravitational constant
m= mass of lighter body
M= mass of heavier body.
r= distance between them.
Although the mass of earth is greater than that of moon , its distance from the sun is larger hence, gravitational force on moon by sun is greater than that on Earth.
Hence the correct order will be
b,c,a.
As you increase current, the strength of an electromagnet intensifies.
True. Series resistance will add up and high total resistance means less current
Answer: The velocity magnitude or the velocity direction chages.
Explanation:
According to Newton's second law of motion, the acceleration of a system moved in same direction and is also directly proportional to the external force which acts on it while inversely proportional to the mass. The formula is: a = F/m
Based on the question, since the object obtains acceleration, then it can be infered that there will be changes in the velocity magnitude or the direction as a result of the motion.
Answer:
8.33 minutes
Explanation:
First let us find out how much time it takes for the light for the sun to reach the earth
Distance between Earth and Sun is 1.5×10¹¹ m
Speed of light = 3×10⁸ m/s
Converting to minutes
So, it takes 8.33 minutes for the light from the sun to reach Earth.
This means that we would be receiving light for 8.33 minutes after the Sun turned off.
