2) mass
3) Force equals mass times acceleration.
4) The acceleration is zero.
5) A balloon floating upward at a constant velocity.
They all are correct. Thank you 'Good luck' :P
Thanks "Good Luck!" All correct
1. To find the momentum of a moving object, you need to multiply its mass by its velocity. Therefore, the correct answer is D. By multiplying its mass by its velocity.
2. Changing the speed of a moving object will not change its mass, acceleration, or momentum. However, it will change its velocity. Therefore, the correct answer is C. Velocity.
3. Newton's second law of motion states that force equals mass times acceleration. Therefore, the correct answer is C. Force equals mass times acceleration.
4. If the total net force on a system is zero and the mass remains constant, it means that the acceleration is zero. This is because according to Newton's second law, if the net force is zero, the acceleration must also be zero. Therefore, the correct answer is C. The acceleration is zero.
5. An object experiencing zero net force means that the external forces acting on it are balanced and cancel each other out. In this case, the object will either be at rest or moving at a constant velocity. The scenario that describes an object experiencing zero net force is A. A balloon floating upward at a constant velocity. Therefore, the correct answer is A. A balloon floating upward at a constant velocity.
