A water-filled manometer is used to measure the pressure in an air-filled tank. One leg of the manometer is open to atmosphere. For a measured manometer deflection of 250 cm water, determine the absolute pressure and the gauge pressure of the tank.

Folding is usually the result of what type of stress

In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80m/s2. Ignore air resistance. A flea jumps straight up to a maximum height of 0.460m.

If a motor neuron involved in a reflex arc is damaged, which event in that arc is least likely to occur?

A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water into air) would bend away from the normal to the medium surface.

3. How is electric potential different than electric potential energy?

Ethan pushes a wooden box across a carpet floor then he pushes the same box across a smooth marble floor why does Ethan find it easier to push the box on the marble floor than carpet floor

Let's now apply our equations for the normal modes of open and closed pipes. On a day when the speed of sound is 345 m/s, the fundamental frequency of an open organ pipe is 690 Hz.
