is the potential energy of the ball as it is half way through the fall, 20 meters high
<u>Explanation:</u>
Given data:
Height of the fall = 20 m
Given that the body is half-way through the fall, it is at above the ground 10 m
We need to find its potential energy (P.E)
Energy due to the body’s position is referred as potential energy. It means the energy when body is at rest. It can be expressed as below,
Where
m – The body’s mass
g - Acceleration due to gravity 
h - Height of the body
By substituting the given values, we get
Since the mass is not provided, just kept it.
Answer:
Explanation:
From the given information:
Since 300 ml of intravenous infusion contains 300 mg of drugs;
Then; 1 ml of intravenous infusion contains (x) amount of drugs
(x) amount of drugs = (300 mg × 1 ml)/ 300 ml
(x) amount of drugs = 1 mg.ml
To calculate the drip rate in drops/minutes by applying conversion factors.
Answer:
As you used two diferent instruments, one is more sensitive than the other.
Explanation:
The sensitivity of an instrument is the minimum amount of magnitude that can be differentiate a measurement system.
In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other
The answer is A),<span>carbon,hydrogen,and oxygen
Hope this helps

Answer:
Evaporation occurs because among the molecules near the surface of the liquid there are always some with enough heat energy to overcome the cohesion of their neighbors and escape. At higher temperatures the number of energetic molecules is greater, and evaporation is more rapid.
