Aglass plate whose index of refraction is 1.57 is immersed in a liquid. the surface of the glass is inclined at an angle of 54° with the vertical. a horizontal ray in the glass is incident on the interface. the liquid is an oil whose index of refraction is 1.40. the incident horizontal ray refracts at the interface. what is the angle that the refracted ray, in the oil, makes with the horizontal?

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?
