A solid ball, of radius 45 mm, rolls down an inclined plane of length 2.5 m. The sphere takes a time of 6.0s to roll down the plane. Assume that the ball does not slip. 1 = 2/5mr^2? a. Calculate the translational velocity of the sphere as it reaches the end of the plane.

b. Calculate the angular velocity of the spere as it reaches the end of the plane.

c. Determine the angle of inclination of the plane.

d. Comment on whether the assumption that the ball does not slip was appropriate in this instance.

Study the diagram showing the range of temperature in the earth’s layers. which temperature most likely corresponds to the asthenosphere? 1,613°c 2,521°c 3,628°c 6,217°c

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

Apiece of metal 75g at 110°c is dropped in a container with 500g at 20°c. the h2o if temperature is 24°c find specific heat capacity of metal
