3.2 The not force acting on object A is zero between 10s and 1 = 20$ Use the graph and a relevant equation to explain
why this statement is TRUE
3.3 Calculate the magnitude of the impulse that object A experiences betwee
= 20 s and f = 50 S

At = 50 s. object A collides with another object. B. which has a momentum o
70 kg-
msEAST
Use the information from the graph and the relevant principle to
3.4 Calculate the momentum of object B after the collision

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.
