Air in a thundercloud expands as it rises. If its initial temperature is 300 K and no energy is lost by thermal con- duction on
Ymorist [56]

Answer:

T_{f}=227K

Explanation:

Given data

Initial temperature of air Ti=300 K

Vf (final volume of air)=2Vi (initial volume of air )

To find

Final temperature

Solution

Since no energy is lost by thermal conduction during the process we categorize  this process as an adiabatic one.Hence we apply;

T_{i}V_{i}^{Y-1}=T_{f}V_{f}^{Y-1}\\T_{f}=T_{i}(\frac{V_{i}}{V_{f}} )^{Y-1}\\

Where air is predominantly a diatomic gas Y=1.4m

Substitute the given values

So

T_{f}=300K(\frac{V_{i}}{2V_{i}} )^{1.4-1}\\T_{f}=227K

8. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bott
nasty-shy [4]

<u>Answer:</u> The ball is travelling with a speed of 5.5 m/s after hitting the <u>bottle.</u>

<u>Explanation:</u>

To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:

m_1u_1+m_2u_2=m_1v_1+m_2v_2

where,

m_1,u_1\text{ and }v_1 are the mass, initial velocity and final velocity of ball.

m_2,u_2\text{ and }v_2 are the mass, initial velocity and final velocity of bottle.

We are given:

m_1=0.4kg\\u_1=18m/s\\v_1=?m/s\\m_2=0.2kg\\u_2=0m/s\\v_2=25m/s

Putting values in above equation, we get:

(0.4\times 18)+(0.2\times 0)=(0.4\times v_1)+(0.2\times 25)\\\\v_1=5.5m/s

Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.

The conductors that carry the current to electrical devices and ? equipment are the heart of all electrical systems. There are a
MariettaO [177]

Answer:

utilization / effects

Explanation:

Utilization equipment are those equipment that makes use of electric energy for the purpose of chemical, electronic, lighting, heating, electro-mechanical or other alike purposes. Hence utilization best suits the first question mark in the question. Secondly, there are associated effects when current flows through a conductor, not responses.
