On the starting blocks, sprinters use their feet to push backward. The blocks respond by pressing forward with a force equal to this with their feet.
<h3>What drives the sprinter forward?</h3>
Vertical forces must be larger than the pull of gravity in order to assist the sprinter in moving forward as gravity is pushing him or her downward. The propulsive force is the force that propelled the runner forward.
<h3>Basketball players must jump straight up into the air, but how?</h3>
An interaction diagram and a free-body diagram should be included in your explanation. The player pushes down on the ground, which pushes up against him in return. As a result of his push being stronger than gravity, the player accelerates upward.

Answer:
4Q
Explanation:
Case 1 :
= mass of the metal
= specific heat of the metal
= Change in temperature = 7 - 4 = 3 C
Amount of heat required for the above change of temperature is given as
Case 2 :
= mass of the metal
= specific heat of the metal
= Change in temperature = 19 - 7 = 12 C
Amount of heat required for the above change of temperature is given as
Hence the correct choice is
4Q
Answer:
50.96 N
Explanation:
weight = mass x gravity
We know that gravity = 9.8 m/s^2 and mass = 5.2 kg.
w = m x g
w = 5.2 kg x 9.8 m/s^2
w = 50.96 N
The weight of the object is 50.96 N (newtons). Hope this helps, thank you !!
Answer: ompare and contrast aerobic physical activity with anaerobic physical activity. ... Aerobic physical activity is better for the cardiovascular system than it is for strength endurance, while anaerobic physical activity is better at building strength endurance than it is at increasing cardiorespiratory fitness.
Explanation: hopefully this helped ;)
