Answer:
Moon and Earth both exert equal force on each other
Explanation:
As we know by the universal law of gravitation the force of gravitation is given by the formula
This is the mutual gravitational force on Earth and Moon by which they attract each other.
So here the force of attraction due to Earth on Moon as well as the Force due to Moon on Earth both will be same in magnitude and opposite in direction.
So here both forces is given as
Moon and Earth both exert equal force on each other
Answer:
I think it depends on the purpose of using Gamma rays. It can be both good and bad
Answer:
Net force= 14 units
The object is unbalanced
Explanation:
The net force refers to the sum of all forces applied to an object. However, the direction of force applied determine the net force. In this question, a boy and girl is pulling a heavy crate at the same time.
This means that the force is in the same direction, hence, the net force will be:
F(N) = 7 + 7 = 14 unit
However, since the pull is occuring at the same direction. This means that the object has a net force, therefore, will move in a particular direction. This means that the OBJECT IS UNBALANCED
Answer:
2.40 x 10⁻¹³ C
Explanation:
= number of electrons = 6.25 x 10⁶
= charge on electron = - 1.6 x 10⁻¹⁹ C
= number of protons = 7.75 x 10⁶
= charge on proton = 1.6 x 10⁻¹⁹ C
Net charge is given as
Q = +
Q = (- 1.6 x 10⁻¹⁹) (6.25 x 10⁶) + (1.6 x 10⁻¹⁹) (7.75 x 10⁶)
Q = 2.40 x 10⁻¹³ C
