How do I solve this scientific notation = 3833.33?

Why does the frequency of a wave increase as the wavelength decreases? A) because the wave speed remains constant B) because the amplitude of the wave must remain constant C) because the frequency must get larger to increase the speed D) because the

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. As she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction.

How is blood flow related to lung function during exercise? Blood vessels are dilated to increase the amount of oxygen carried in the blood, and the lungs work harder to meet the body's oxygen demands.

One group of scientists feel that global warming affects the frequency of hurricanes. Another group of scientists believe that global warming does not affect the frequency of hurricanes, but it makes the average hurricane stronger.

In an experiment, all participants receive a treatment but those in the control group recieves a false treatments

Recoil is noticeable if we throw a heavy ball while standing on a skateboard. If instead we go through the throwing motion but hold onto the ball, without friction effects our net recoil will be A) zero. B) the same as before.
