Answer:

The ping pong ball is hollow.

Explanation:

Since a ping pong ball, unlike the golf ball, is only filled with air, it is less dense. Air is notably LESS dense than solids, which is what comprises the inside of a golf ball.

A gas cylinder contains argon atoms (m=40.0 u). The temperature is increased from 286 K (13°C) to 362 K (89°C) (a) What is the c

Rama09 [41]

Answer:

(a). The change in the average kinetic energy per atom is $1.57\times10^{-21}\ eV$ .

(b). The change in vertical position is 2413 m.

Explanation:

Given that,

Mass = 40.0 u

The increased temperature from 286 K to 362 K.

(a). We need to calculate the change in the average kinetic energy per atom

Using formula of kinetic energy

$\Delta K.E=\dfrac{3}{2}k\Delta t$

Put the value into the formula

$\Delta K.E=\dfrac{3}{2}\times1.38\times10^{-23}\times(362-286)$

$\Delta K.E=1.57\times10^{-21}\ eV$

(b). The change in potential energy of the container due to change in the vertical position

We need to calculate the change in vertical position

Using formula of potential energy

$\Delta U=mg\Delta h$

$\Delta h =\dfrac{\Delta U}{mg}$

$\Delta h=\dfrac{1.57\times10^{-21}}{40.0\times1.66\times10^{-27}\times9.8}$

$\Delta h=2412.7=2413\ m$

Hence, (a). The change in the average kinetic energy per atom is $1.57\times10^{-21}\ eV$ .

(b). The change in vertical position is 2413 m.

How long would it take me to travel 48 milllion miles at 200000 mph?

MakcuM [25]

For this question, you must divide 48 million by two hundred thousand to get your answer. The quotient of these number is 240, which if reduced to days, is exactly ten days.
