Answer:
Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.
Explanation:
The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.
Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".
Answer:
false
Explanation:
every object will always have the force of gravity acting upon it.
Answer:
I = 1.38 A
Explanation:
Given that,
Charge, q = 5000 C
Time, t = 1 hour = 3600 s
We need to find the current intensity. The current intensity is equal to the electric charge per unit time. It can be given by :

Substitute all the values in the above formula

So, the current intensity is 1.38 A.
