The average velocity V of gas molecules is represented by the formula V=√ ( (3kt)m). The velocity is measured in meters per second, t is the temperature in Kelvin, and m is the molar mass of the gas in kilograms per mole. The variable k represents a value called the molar gas ...
Thus, increasing a planet’s angular velocity decreases the average ground heat flux via reduction of instantaneous heat fluxes. This causes the ratio in Eq. (24), i.e. the solar flux fraction stored into the ground to remain conservative across planet spin rates. The Law of Energy ...
The formula used is F=p/t, where t is found to be 0.2 m / 484 m/s = 4.13 * 10^-4 seconds. The factor of 2 is multiplied on the impulse because each impact on a given wall involves the molecule striking the wall with velocity v and bouncing back, resulting in a net change in...
The probability density for speeds (magnitude of velocity) v of gas molecules proportional to f(v) = v^2 e - \frac{mv^2}{2kT}. Is the distribution function f(v) normalized? Find the average speed. (Hint: don't forget to normalize f(v) if it is...
Explicit formulae are given for averages over Maxwell distributions of any physical quantity whose dependence on the collision velocity g can be expressed as a power g r, or sum of such powers. Concepts and formulae are applied to the comparison of ion beam scattering with drift tube ...
Upon impact, the apple comes to rest in 0.1 s, and 4 cm2 of the apple comes into contact with the surface during the impact. The average pressure exerted on the apple during the impact is 21,000 Pa, according to answer choice (B). This can be calculated by finding the velocity of ...
