X = Xo cos ω t
Explains the back and forth motion of the pendulum
Answer:
mantle convection is the very slow creeping motion of earths solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.
Answer:
a) 0.022%
b) 10014.32 lb
Explanation:
a) Percentage uncertainty would be

Percent uncertainty is 0.022%
b) For 1 kg uncertainty mass in kg would be

Mass in pounds would be

Mass in pound-mass is 10014.32 lb
A wave will "break" because the bottom interferes with its oscillatory motion. Breaking of waves may occur anywhere that the amplitude is sufficient, including in mid-ocean. When waves enter shallow water they break because the motion of water in lower part of the wave nearest the bottom is slowed by friction so that their oscillation is faster than its supporting portion at the bottom. Thus, the wave collapses forward and breaks.
