"List, from beginning to end, the stages in the weather as a cold front goes by: (a) warm air is forced upward where it cools; (
RSB [31]

Answer:

(a) warm air is forced upward where it cools;

(c) cumulonimbus or nimbo-stratus clouds form

(d) thunderstorms with heavy showers and gusty winds occur"

(b) air cools and sinks, pressure rises, rain stops;

Explanation:

  • A cold for front is a denser air , as that forms under the warmer and lighter air mass and this causes a low pressure along the  cold form and thus causes the formation of a thunderstorm where enough moisture is present and  drop in temperature occurs and in the northern hemisphere the cold front shifts the winds to from the southwest to northwest clockwise.

A sample of a material has 200 radioactive particles in it today. Your grandfather measured 400 radioactive particles in it 60 y
sukhopar [10]

Answer:

Amount of radioactive particles left after 60 years = 100 particles.

Explanation:

Amount of radioactive particles before 60 years = 400

Amount of radioactive particles present today = 200

That is radio active particles reduced to half. That is 60 years is half life of this radio active material.

After 60 years this 200 radio active particles will reduce to half.

Amount of radioactive particles left after 60 years = 0.5 x 200 = 100 particles.

A certain ideal gas has molar heat capacity at constant volume CV. A sample of this gas initially occupies a volume V0 at pressu
ANTONII [103]

Answer:

Explanation:

The processes are described on the image attached below. The isobaric process consists of an horizontal line, the adiabatic expansion is described by a polytropic curve:

P_{2} \cdot V_{2}^{\gamma} = P_{3} \cdot V_{3}^{\gamma}

Where:

\gamma = \frac{c_{p}}{c_{v}}

\gamma = 1 + \frac{R}{c_{v}}

Final pressure is:

P_{3} = P_{2}\cdot \left(\frac{V_{2}}{V_{3}}  \right)^{\gamma}

P_{3} = P_{o}\cdot \left(\frac{1}{2}\right)^{\gamma}

P_{3} = \frac{P_{o}}{2^{\gamma}}
