Lucas left a metal bowl and a wooden bowl outside overnight. the next morning, he picked up
the bowls to bring them inside. he noticed that the metal bowl felt much cooler than the wooden
bowl. his father explained that both bowls were actually the same temperature. which statement
best describes why the metal bowl felt cooler even though the bowls were the same
temperature?
a. metal transfers heat away from the skin by conduction, creating the sensation of coolness.
b. wood transfers heat away from the skin by convection, creating the sensation of warmth.
c wood transfers heat to the skin by radiation, creating the sensation of warmth.
d. metal removes moisture from the skin by absorption, creating the sensation of coolness,

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
