Which of the following properties of light can only be explained by wave theory and not by the Photoelectric effect? reflection refraction interference velocity

Billy drops a water balloon from the roof of his house. Since the balloon began with an original velocity of zero, how far above ground was the balloon if it took 2.5 seconds to hit the ground?

The Pilot of a plane measures an air velocity of 165Km/h south relative to the plane. An observer on the ground sees the plane pass overhead at a velocity of 145 Km/h toward the north.

Explain what it means when we say that Earth's oceans are in hydrostatic equilibrium. Now suppose you are a scuba diver. Would you expect the pressure to increase or decrease as you dive below the surface to a depth of 200 feet? Why?

What is the behavior that takes place when two waves of equal amplitude collide abd sum up to a bigger wave.

An ideal gas is held in a canister of volume V, at pressure P, and temperature T. Subsequently, the movement of a piston doubles the volume (to 2 V), while the temperature is also doubled (to 2 T), in absolute units (e. g. Kelvin).

Match the word with its definition. Column A1. rotational speed 2. tangential speed 3. centripetal force 4. centripetal acceleration 5. Newton's Second Law 6. Newton's First Law Column Ba. 1 revolutions per minute (RPM) b.

How do you determine the speed or velocity of an object using a distance vs. time graph

What is the median of 5 12 7 15 3 6 1

If you double the velocity of an object, you increase its kinetic energy by a factor of what?

2. Modern aircraft carriers use a steam powered catapult system to launch jets from a very short range. These catapults can provide a constant acceleration to bring jets up to speed in only two seconds.
