Radon is a gas at the temperatures we live in.
The gas is slightly radioactive, and it's soluble in water.
It's a widespread source of natural groundwater pollution,
and is responsible for the elevated level of radiation that's
often measured in the basements of homes.
Explanation:
It is given that,
Initial temperature,
Pressure,
Compression ratio,
Let T₂ is the final temperature of air. Using the relation for reversible adiabatic process as :
............(1)
Where,
For air, and
So, equation (1) becomes :
So, the final temperature of air is 719.49 K. Hence, this is the required solution.
Knowing that when you throw something in the air, the speed will be 0m/s.
The acceleration due to gravity is 9.8m/s^2.
v2=0
v1=24
a=9.8
The formula is:
v2=v1+a(t)
v2-v1/a=t
0-24/9.8
24m/s/9.8m/s^2=t (You can choose which direction is positive and negative)
2.45s=t
t=2.45*2s (Since you calculate both going up and down)
t=4.9s
Answer:
Fats and waxes are solid at room temperature because they are made of saturated fatty acids. In contrast, oils are mostly unsaturated fatty acids. ... In contrast, unsaturated fatty acids have several kinks in their structure and therefore, are liquid at room temperature.
Answer:
C. D.C.
Explanation:
The current that is being described here is D.C. or direct current. It is the D.C. that moves in one direction from negative to positive. May be created by a battery. It is different from the A.C.( alternating current whose polarity changes regularly). It is A.C. that is used in electrical outlets and not D.C.So, the current option is C.
