Answer:

breaking apart of atoms of certain elements to release rays of energy or particles.

Atoms are the building blocks of elements. However, some atoms have an excessive number of neutrons or protons in their nuclei. This causes an imbalance in the forces that keep them together, resulting in an excessive amount of internal energy. These atoms are referred to as radioactive or unstable.

Calculate the force between two objects that have masses of 70 Kilograms and 2,000 kilograms separated by a distance of 1 meter

Hunter-Best [27]

9.3 x 10⁻⁶N

Explanation:

Given parameters:

Mass 1 = 70kg

Mass 2 = 2000kg

distance = 1m

Unknown:

force between them =

Solution:

The force between the two masses will be a gravitational force of attraction.

F = $\frac{G m_{1}m_{2} }{r^{2} }$

G is universal gravitation constant = 6.67430×10−¹¹ N⋅m²/kg²

r is the distance between the two masses

Substituting the parameters:

F = $\frac{6.67 x 10^{-11} x 70 x 2000}{1^{2} }$ = 9.3 x 10⁻⁶N
