For a given wave if the frequency doubles the wavelength?
. . . reduces by half.
Does gravity stop a ball from rolling?
Momentum is the product of mass and velocity. When an object slows down, the object reduces in velocity. Since Mass is constant, when velocity reduces momentum reduces. thus momentum can be what stops a rolling object. However, a resistive force the reason for the reduction of velocity and subsequently halting.
What is your velocity if you traveled 2000 m south in 400 seconds?
Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).
When area reduces velocity increases or decreases?
If you're talking about something like gasses, and by area you mean volume, and all other factors are held constant, then the pressure increases.... the velocity either increases or doesn't change, it certianly doesn't decrease.
How is gravity related to terminal velocity?
Based on the 9th grade book of Physical Science... Gravity is a force that acts between two masses, and Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. So, gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration... which ties together terminal velocity.

What happens to the frequency as the electromagnetic wave gets longer?
the frequency reduces in value. The longer the wavelength the lower the frequency.
How does channel roughness influence river velocity?
These obstacles causes friction between water and rocks.This ultimately reduces the velocity of river water.The more roughness of the channel, the less the river`s velocity.
What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
Why do firstbasemen wear trappers?
The exceeding amount of velocity on the ball when its thrown to first. It can damage the palms and hands, trappers reduces the risk

As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the frequency of the light?
colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength

How does destructive interference affect the amplitude of a wave?
Destructive interference affect the amplitude of a wave because two identical waves with similar amplitude and wavelength, arrive in anti phase, leading to a zero displacement.
Can you find the examples when the rate of change of momentum reduces?
Ok, we know that momentum is mass*velocity. To create a change we need to either change velocity or mass. This is where elastic and inelastic collision come into place. Rate of momentum changes in both collision cases. To reduce the rate of change of momentum, even though this is a little vague, you'll need to reduce the changes in either mass or velocity. Such that the momentum at point A, for instance, reduces momentum at point B and then C and so forth (by constantly reducing velocity). A live example is gas molecules, they have numerous collisions and the momentum constantly changes by variation in velocities. But remember the momentum of a system is conserved, that's a thing you'd probably need to know too to understand. Hope that helps.
