Answer: option d.

Explanation:

In this situation, we can suppose that the football player has a velocity of 2m/s in the positive x-axis, and the ball has a velocity of -5m/s in the x-axis.

If we step in the point of view of the football player, all the previous x-axis now moves with the same velocity that the player had, but in the other direction, so all the axis now moves with a velocity of -2m/s. And the ball that also is in the axis also gets this "boost" in velocity.

So now the velocity of the ball is -5m/s -2m/s = -7m/s where the minus sign is because of the situation that I crafted.

So the correct option is the option D

Brut [27]

This would happen later at night or early in the morning.

The reason being land becomes warm and cold quicker than the water because of the heat capacity. So during the day water warms up because of sunlight but at night the land becomes a lot cooler as compared to the water which is still war. So the air over water is significantly warmer than the air over land.

Any two application of gravity
Brrunno [24]

Answer:

Well the definition of an application is the act of putting to a special use or purpose so lam assuming that you want specific uses that scientists make of gravity in their work.

Well our first application has helped us to send satellites around the solar system with what Nasa calls gravity assist. Using a particular planets gravity to slingshot a satellite to another destination. Look it up.

The next application much simpler but here on Earth. There are many hydro-electric power stations in use all over the world. Water is stored at a high level and released falling 100s of metres to a turbine where it generates electricity.

Hope that helps.
