Answer: momentum afterwards = 1040.4kgm/s
Explanation:
Answer:
Acceleration= final velocity - initial velocity / time
= (15 - 0)/ 5
= 3 m/s^2
Force = mass X acceleration
= 2 X 10^3 X 3
= 6 X 10^3 N
3.92N
Explanation:
Given mass:
Mass of bag = 400g
The mass of a substance is the amount of matter it contains.
Weight of a substance is the vertical force acting on a body in the presence of gravity.
Weight = mass x gravity
Since the mass of the bag is 400g;
Now we convert to kg
1000g = 1kg
400g =
= 0.4kg
Weight of bag = 0.4kg x 9.8m/s²
Weight of bag = 3.92N

The third one.
The nucleus of an atom is made up of protons and neutrons. Protons and neutrons have the same relative mass (rounded to 1). Electrons have an extremely small mass.
Therefore, the particles in the nucleus are more massive than those in the electron cloud.
