Answer: 
Explanation:
We have this concentration in units of 
:
And we need to express it in 
, knowing:
Hence:
Answer:
1+1=2
Explanation:
You just need to add and voila the answer
Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.
Explanation:
It is given that,
Force on piston, F₁ = 8800 N
Area, 
Area, 
Let F₂ is the force exerted on the second piston. Using Pascal's law as :
Pressure at piston 1 = Pressure at piston 2
So, the force exerted by a second piston is 35200 N. Hence, this is the required solution.
Answer:
The correct answer is H ÷ ¹/₂T
Explanation:
The formula for velocity is distance covered ÷ time.
Neglecting air resistance;
If the ball's time of overall time flight is T, the time it will take for the second half/return trip is ¹/₂T.
If the ball's maximum height above its released point is H, the height will also be the distance it covered for the second part of the trip since the student caught the ball in the exact same place the ball was thrown. Hence, the distance for the second half of the trip will be H.
Since velocity = distance/time
The average velocity during the second half of the trip will be = H ÷ ¹/₂T
