dmitriy555 [2]

Answer:

The person going to the highest apartment door.

Explanation:

Since gravitational potential energy, U = mgh where h is the height above the ground. The person with the highest gravitational potential energy would be the person going to the highest apartment door if we assume that their masses are the same.

What did Rutherford’s model of the atom include that Thomson’s model did not have?
Ksivusya [100]
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.

A weather balloon is designed to expand to a maximum radius of 24 m at its working altitude, where the air pressure is 0.030 atm
nlexa [21]

Answer:

<em>Radius at liftoff 8.98 m</em>

Explanation:

At the working altitude;

maximum radius = 24 m

air pressure = 0.030 atm

air temperature = 200 K

At liftoff;

temperature = 349 K

pressure = 1 atm

radius = ?

<em>First, we assume balloon is spherical in nature,</em>

<em>and that the working gas obeys the gas laws.</em>

from the radius, we can find the volume of the balloon at working atmosphere.

Volume of a sphere = \frac{4}{3} \pi r^{3}

volume of balloon = \frac{4}{3} x 3.142 x 24^{3} = 57913.34 m^3

using the gas equation,

\frac{P1V1}{T1} = \frac{P2V2}{T2}

<em>The subscript 1 indicates the properties of the gas at working altitude, and the subscript 2 indicates properties of the gas at liftoff.</em>

imputing values, we have

\frac{0.03*57913.34}{200} = \frac{1*V2}{349}

0.03 x 57913.34 x 349 = 200V2

V2 = 606352.67/200 = <em>3031.76 m^3  this is the volume occupied by the gas in the balloon at liftoff.</em>

from the formula volume of a sphere,

V =  \frac{4}{3} \pi r^{3} =  \frac{4}{3} x 3.142 x r^{3} = 3031.76

4.19r^{3}  = 3031.76

r^{3} = 3031.76/4.19  

radius r of the balloon on liftoff = \sqrt[3]{723.57} = <em>8.98 m</em>
