Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. ... Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
Centripetal Force, F = mv²/r
Where m = mass in kg, v = velocity in m/s and r = radius of curvature in m.
Centripetal Force, F = 2000 * 25² / 80. Use your calculator.
F = 15 625 N.
Answer:
A book containing information on various types of science related topics.
Answer:
v1 = a t + v0 = 2.5 * 5 + 5 = 17.5 m/s after 5 sec
v2 = o * 6 + 17.5 = 17.5 m/s after 11 sec
S1 = V0 t + 1/2 a t^2 = 5 * 5 + 1.25 * 5^2 = 56.25 m
S2 = 17.5 * 6 = 105 m
S = 56.3 + 105 = 161 m
Vav = S / t = 161 m / 11 s = 14.6 m/s
Answer:
Levels of real per capita GDP are often cited to indicate living standards are higher in one country than another, and, by implication, that some systems of government or sets of government policies are better than others, but this measure of comparative living standards is so flawed as to be practically useless.
