Answer:
It also increases
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass, and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
It is an ion.
A hydrogen atom is an atom of the chemical element hydrogen.
The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force.
An atom is a neutral species.
Hence, it must have same number of electrons and protons. On other hand, ions have charge.
So, the number of protons and electrons are not same.
According to the question,
Hydrogen has one proton, two neutrons, and no electrons.
This signifies that overall charge of species is +1.
Hence, it is an ion.

By definition we have to:
It is the capacity that the human being has to think at the moment of acting before certain activities, about the possible risks that these can have, and modify their behavior so as not to receive or produce unnecessary damages.
In other words we can say that prudence means acting with caution in certain activities.
Answer:
Prudence means acting with caution.
c.Caution
a graduated cylinder
an eye dropper
a beaker
a buret
Answer: a buret
A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.
A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.

c. change in mass/change in volume
d. change in pressure/change in time
