I think the correct answer would be none, because the wall will block the radiation. Alpha particles can only penetrate a very thin sheet of paper and is totally blocked by the concrete. As these particles move through the air, it loses energy from the collisions with air molecules making it less penetrating.<span />
The important thing in this question is the unit. The mass equals density * volume. 3.1 L = 3.1 * 10^3 cm3. So the mass is 3.193*10^3 g. 1 pound = 453.95 g. So the answer is 7.04 pounds.
Answer: Option (e) is the correct answer.
Explanation:
An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.
For example,
So, here amount of reactants that is, nitrogen gas and hydrogen gas will be constant along with constant amount of formation of product that is, ammonia here.
In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.
Thus, we can conclude that all the given statements are true.
High because obvs , ph is around the last letter in the alphabet so the ph is going to be high as well , hope this is correct
The greater the angle, the more of the moon we see illuminated.
<h3>How does the value of the angle correlate with the appearance of the moon?</h3>
The moon is a large celestial body which revolves around the earth. The moon is attracted to the earth and remains in its orbit around the earth due to the gravitational forces of attraction between the moon and the earth.
The appearance of the moon has eight phases which area;
- new Moon,
- waxing crescent,
- first quarter,
- waxing gibbous,
- full Moon,
- waning gibbous,
- third quarter and
- waning crescent
The angle between the Sun and the moon correlates to its appearance.
The greater the angle, the more of the moon we see illuminated.
In conclusion, the moon is a celestial body which revolves around the earth.
