Answer:
Force of gravity, F = 0.74 N
Mass of an object, m = 1.2 kg
Distance above earth's surface,
Mass of Earth,
Radius of Earth,
We need to find the force of gravity above the surface of Earth. It is given by :
R = r + d
R = 25370000 m
F = 0.74 N
So, the force of gravity on the object is 0.74 N. Hence, this is the required solution.
Answer:
The average distance between the Earth and the Sun is about 93 million miles. All of the planets, comets, and asteroids in the solar system orbit the Sun. The average distance between the Earth and the Sun is 92,955,807 miles.

Answer:
Negative
Explanation:
Liquid electrolyte inside battery has work to transfer the charge from one terminal to other terminal..
So here this is carried out by the charge which has more mobility and it must be more in numbers.
So here for more mobility we have to take the negative charge or free electrons present in the electrolyte which carry electricity from one terminal to other terminal with least resistance
so here correct answer would be
b.) Negative
Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B =
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
