Answer:
Explanation:
Initial is all kinetic energy
final is all potential energy (spring)
½kx² = ½mv²
x = √(mv²/k) = √(1.3(2.8²) / 800) = 0.01274 m or about 1.3 cm
L = L₀ - x = 0.439 - 0.013 = 0.426 m
F = kx = 800(0.01274) = 10.192 or about 10.2 N
Electrical resistance is opposition to the flow of current in an electric circuit: resistance converts electrical energy to thermal energy, and in this regard is similar to mechanical friction. Resistances are said to dissipate electrical energy as heat.
Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. ... Maritime polar (mP) air masses are cool, moist, and unstable.
