D. I hope my answer helps you!
Answer:
The inertia of an object does not change. The only time the inertia would change is when the object changes mass. ... The acceleration of an object depends on the mass of the object as well as the force exerted. This means that if the mass is smaller, the acceleration will be greater.

Answer:
ExplanaThis is a way of measuring how much gravity there is. The formula is: weight/mass = gravitational field strength.
Gravitational field strength = Weight/mass unit is N/kg
Weight = mass x gravitational field strength unit is N
On Earth the gravitational field strength is 10 N/kg. Other planets have different gravitational field strengths. The Moon has a gravitational field strength of 1.6 N/kg. You might have seen films of astronauts leaping high on the moon.
Here on Earth, if I jump I am pulled back to ground by gravity. What is my weight? My mass is 80kg and if we multiply by gravitational field strength (10N/kg) - my weight is 800N. Now if I go to the moon, my mass will be the same, 80kg. We multiply that by the moon's gravitational field strength, which is 1.6 N/ kg. That means my weight on the moon is 128N. So I have different weights on the Earth and on the Moon. That's why astronauts can jump high into the air on the moon - they're lighter up there.
Jupiter is a very large planet with strong gravitational field strength of 25 N/ kg. My body is 80kg. If I go to Jupiter my weight is going to be 25 x 80 = 2,000 N. That means I wouldn't be able to get off the ground or stand up straight! I would probably be lying down all the time there. So weight varies depending on which planet you are on. You can find out more yourself by looking up tables of weight on different planets.tion:

Answer:
The 7.0-kg bowling ball with a speed of 6.0 meters per second
Explanation:
Momentum is p=mv
m = mass, v = velocity. (velocity is speed with direction)
1. 0.046-kg golf ball with a speed of 60.0 meters per second.
The mass is 0.046kg , velocty is 60.0
p= mv = 0.046 x 60 = 2.76kg
2. 7.0-kg bowling ball with a speed of 6.0 meters per second
Mass is 7kg, velocity = 6
p=mv = 7 x 6 = 42kg
The 7.0kg bowling ball has more momentum because 42 is greater than 2.76.
Answer:
The car exerts a force on the rock, and the rock exerts a force on the car. The two forces are equal in magnitude.
Explanation:
It is given that,
Mass of the car, M = 1500 kg
Mass of the rock, m = 0.1 kg
It is mentioned that a car traveling along a road is hit by a rock that creates a small crack in the car’s windshield. We need to find the correct option that describes the interaction between the windshield and the rock. We know that when one object hits another object, the force applied by object 1 on object 2 have equal and opposite reaction as per the Newton's third law of motion.
So, the car exerts a force on the rock, and the rock exerts a force on the car. The two forces are equal in magnitude. Hence, the correct option is (c).
