Aforce of 100 n is applied to the brake pedal, which acts on the cylinder—called the master—through a lever. a force of 500 n is exerted on the master cylinder. pressure created in the master cylinder is transmitted to four so-called slave cylinders. the master cylinder has a diameter of 0.55 cm, and each slave cylinder has a diameter of 2.50 cm. how much pressure is transmitted in the hydraulic system? express your answer in pascals and in atmospheres.

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

Identify the theory that can be used to explain each phenomenon. answers diffraction: wave theory interference: wave theory reflection: both particle and wave theories refraction: both particle and wave theories

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
