Complete the paragraph about kinetic energy. Use . Jimmy nutron and his dad are each riding a swing. jimmy has a mass of 25 kilograms, and his dad has a mass of 30 kilograms. jimmy's swing moves with a velocity of 10 meters/second, while dad’s swing moves with a velocity of 8.5 meters/second. jimmy’s kinetic energy is joules. jimmy’s kinetic energy is greater than dad’s because

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.

Which component of the earth’s atmosphere is decreased due to photosynthesis?
