C. boiling point is the correct answer! Please mark brainliest! Have a nice day!
In my opinion,I think the answer is b.You can control variables more easily by doing different things for different purposes.
Answer:
i think it would be increased water retention
Answer: In all cases, gravitational potential energy, respect from a common reference level (street level for instance) is the same.
Explanation:
Gravitational potential energy, comes from the action of the gravitational field, which is a conservative one.
This means, that if someone does work against the field (for instance lifting a weight from the ground to a given height), and then drops the weight, the work done by the field will be exactly the same.
Otherwise, the object would have remaining energy after returning to the starting point, which would violate the laws of physics, specially Thermodynamic's 2nd Law.
For this reason, the gravitational potential energy only depends from the height, and is independent from the path taken to reach there.
Answer:
Number of electrons, n = 395.47
Explanation:
It is given that,
Force between two spheres, 
Distance between spheres, r = 35 cm = 0.35 m
A force of repulsion is acting on the spheres. It is given by :
Let n is the number of electrons on the spheres. So,
q = n e
n = 395.47
So, the the number of excess electrons on the spheres are 395.47. Hence, this is the required solution.
