The escape speed from a very small asteroid is only 20 m/s. If you throw a rock away from the asteroid at a speed of 26 m/s, what will be its final speed

In physics the desire of an object to keep doing what it is doing is termed?

Can anybody me with this? ? (picture included.)

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.
