A disk with a radius of 0.1 m is spinning about its center with a constant angular speed
of 10 rad/sec.
What are the speed and magnitude of the
acceleration of a bug clinging to the rim of the
disk?
1. 0.1 m/s and 1 m/s2
2. 1 m/s and 0 m/s2
(Disk spins at constant
speed.)
3. 1 m/s and 10 m/s2
4. 10 m/s and 10 m/s

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

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.
