Types of Air Resistance: There are three main types of drag in aerodynamics – Lift Induced, Parasitic, and Wave. Each affects an objects ability to stay aloft as well as the power and fuel needed to keep it there.
Answer:
Normal force of 10,000N
Explanation:
From the question, the weight the car exerts on the pavement is 10,000N.
The pavement exerts upward and perpendicular contact force called normal force on the car to support its weight. Also, the normal force is equal and opposite to the weigh of the car.
Hence the pavement exerts normal force of 10,000N back on the car to prevent it from passing through it.
gravity is the force on the object directed down the plane
<em>I am gonna have to say A 0.02 because 2 meters a second is way too fast 0.2 is a little more than reasonable and if 2 meters a second is too fast then 20 is off so</em> A. should be most reasonable
Answer:
More than 105 m/s
Explanation:
Electric potential is defined as the work done in moving a charge from one point to another in an electric field.
Since the charge moved from a region of higher potential (10V) to a region of lower potential (5V) the speed is bound to increase because lesser work will be required to keep it moving; this implies that the kinetic energy will increase since the same amount of energy that kept it moving in the 10V region is still supplied to it ( energy is conserved).
Another simple way to help understand this is that whenever the potential energy of a particle decreases its kinetic energy increases; which implies that its velocity must have increased also, as long as the total energy of the system is conserved.
