The lamps in a string of decorative lights are connected in parallel across a constant - voltage power source. What happens if one lamp burns out? (Assume negligible resistance in the wires leading to the lamps.) The other lamps get brighter equally. The other lamps get dimmer equally. The other lamps get brighter, but some get brighter than others. The brightness of the lamps will not change appreciably. The other lamps get dimmer, but some get dimmer than others.

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6ā0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
