<h3>Answer:</h3>
-4.73 m/s²
<h3>Explanation:</h3>
Each jumper represents about 1/2 of 1% of the mass of the train, so together they total about 3.5% of the mass of the train. If the mass decreases by 3.5% and the braking force remains the same, the acceleration (magnitude) will increase by about 3.5%.
The acceleration will be about 0.17 m/s² more (in magnitude) than it was, or about -4.73 m/s².
Answer:
Weight is a force
Explanation:
Weight is the force of gravity on a mass. It can also be seen through this equation: F=ma, where m is the mass of the object and a is the acceleration of gravity.
Answer:increasing any of them, either mass or speed by 1unit will cause an increase in energy,
Explanation:
By increasing any of them, either mass or speed will cause an increase in energy.
Because kinetic energy is proportional to mass and also directly proportional to velocity
When light crosses the boundary between layers with different densities, the light is refracted. (A).
