A softball player leaves the batters box, overruns first base by 3.0 meters, and then returns to first base. Compared to the total distance traveled by the player, how much smaller or larger is the magnitude of the players total displacement from the batters box?

Answers

The distance traveled during his run is 6 meters more than his displacement. Displacement only depends on the end points. The route taken is irrelevant to displacement.

Gaseous helium is in thermal equilibrium with liquid helium at 6.4 K. The mass of a helium atom is 6.65 × 10−27 kg and Boltzmann’s constant is 1.38066 × 10−23 J/K. Determine the most probable speed of a helium atom. Answer in units of m/s.

Answers

Answer:

162.78 m/s is the most probable speed of a helium atom.

Explanation:

The most probable speed:

$v_(mp)=\sqrt{(2K_bT)/(m)}$

$K_b$ = Boltzmann’s constant = $1.38066* 10^(-23) J/K$

T = temperature of the gas

m = mass of the gas particle.

Given, m = $6.65* 10^(-27) kg$

T = 6.4 K

Substituting all the given values :

$v_(mp)=\sqrt{(2* 1.38066* 10^(-23) J/K* 6.4 K)/(6.65* 10^(-27) kg)}$

$v_(mp)=162.78 m/s$

162.78 m/s is the most probable speed of a helium atom.

What is the energy of a photon whose frequency is 6.0x10^20 hz?

Answers

Energy of photon is given by formula

$E = h\nu$

here

h = Planck's constant

$h = 6.6* 10^(-34)$

$\nu = frequency = 6 * 10^(20)Hz$

now the energy is given by

$E = 6.6*10^(-34) * 6 * 10^(20)$

$E = 3.96 * 10^(-13) J$
