How much pressure do you experience when you balance a 0.63 kg basketball on the tip of your finger assuming a contact area of 1 cm^2 (1 x 10^-4 m^2). Recall P = F/A and 1 Pa = 1 N/m^2. a) In Pascals (Pa) and b) In kilopascals (kPa)

Which describe reflection? check all that apply. light bounces off a boundary.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
