A pressure cooker has a mass of 1.5 kg and temperature of 30°C. The specific heat capacity of the alloy from which the pressure cooker is made up of is 1000/kg
What will be its temperature when 7.5 *10') of heat is supplied to it? ​

You throw a baseball directly upward at time t = 0 at an initial speed of 12.3 m/s. what is the maximum height the ball reaches above where it leaves your hand? at what times does the ball pass through half the maximum height? ignore air resistance and take g = 9.80 m/s2.

Describe uniform velocity and variable velocity in short

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
