\(V_2 = \frac{P_1V_1T_2}{P_2T_2}\) \(V_2 = \frac{700 \times 2000 \times 273}{760 \times 300}\)

An increase in atmospheric pressure actually decreases the rate of evaporation. Higher pressure means more air molecules are pushing down on the surface of the water, making it physically more difficult for water molecules to escape into the air as vapour.

Q = mL + mcθ = 1 x 3.5 x 10 5 + 1 x 2.1 x 10 3 x 30

Pitch, loudness, and atmospheric pressure do not affect sound velocity. Wind traveling in the same direction of sound affects its velocity. wind can slow down or accelerate the speed of sound, depending on whether it is blowing in the same direction or in the opposite direction to the sound signal.

F = BQV B = \(\frac{F}{QV}\) B = \(\frac{1.8 \times 10^{-8}}{1.0 \times 10^{-8} \times 3.0 \times 10^{-2}}\)

V = \(\frac{M}{D}\) = \(\frac{3.06}{10} \times \frac{1000}{0.9} = 340\)

When terminal velocity is attained, The equation of motion becomes mg - V - U = 0 \(\therefore\) mg = W = U + V

a = \(\frac{F}{M} = \frac{15}{0.25} = 60\)

Heat is a form of energy (heat energy). The S.I unit of energy generally is Joules (J).

Force x Distance = Power x Time Time = \(\frac{Force \times Distance}{Power}\) = \(\frac{20 \times 500}{0.4 \times 1000}\) = 25.0s

Pressure = \(\frac{Force}{Area}\) Force = mass x acceleration \(\therefore\) Pressure = \(\frac{mass \times acceleration}{Area}\) = \(\frac{kg \times m \times s^{-2}}{m^2}\) = kg m\(^{-1}\) s\(^{-2}\)
