Answer:
-35 
Explanation:
<u>Deceleration is the complete opposite of acceleration and is calculated by adding a negative sign to the formula for finding acceleration.</u>
Since acceleration is calculated by diving the change in velocity with time, deceleration will become:
Deceleration = -Δv/t, where Δv = change in velocity and t = time
In this case, Δv = 70 m/s and t = 2 s, hence;
Deceleration = -70/2 = -35
<em>The deceleration is 35 </em><em>.</em>
Time , Work, Horsepower
Explanation:
In General, Power is defined as rate of doing work in physics.
1.) By work and Time, we can calculate power as follows,
Power = Work done per unit Time
= Work done / time
2.) From Horsepower we can directly get the power.
Horsepower (hp) is a unit to measure the power, or the rate at which work is done, usually in the output of engines or motors. There are many types of horsepower. Two common ways of defining horsepower is being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
Answer:
D
Explanation:
What can be infer from Mr. F situation is that his body is raising blood pressure by both increasing blood volume with all this fluid intake and increasing heart rate. Something may be wrong with his blood volume.
Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

Answer:
Acceleration due to gravity 9.8 m/s^2
Explanation:
When an object drops down towards earth from certain height than it comes down with an acceleration of 9.8 m/s^2 which is constant throughout the dropping until the falling objects hits the ground and coming to rest.
