What is the magnitude of the force required to accelerate a ball of mass 5 kg from rest to a speed of 20 m/s for a distance of 0.50 m

Which would not reduce the amount of green house gasses in the air

Match each scenario to the form of energy it represents

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
