Traditional incandescent light bulbs were used for many years and produce bright light, but the bulbs rapidly become too hot to touch. Halogen bulbs are slightly more efficient. Compact fluorescent light bulbs (CFL) and Light-emitting diode light bulbs (LED)

generate less thermal energy. Based on this information, what types of bulbs are most likely indicated by the illustration

A)

incandescent and halogen

B)

incandescent and LED

halogen and CFL

D)

CFL and LED

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.
