A car starts from rest and accelerates uniformly over a time of 6.92 seconds for a distance of 163 m. Determine the acceleration of the car. (Round to one decimal place.) (okay but can someone actually help because if I don't pass this ima fail physics)

An object's buoyant force and weight mean the same thing.a. trueb. false

How does an observation about an object differ from an inference about that object

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
