Which of the following water molecules exists in the greatest abundance?

Physics

Answer:

d. H216O

Explanation:

Hello,

Water is a chemical compound which has two hydrogen atoms and one oxygen atom.In solid state, it is ice where as in gas state, it is steam.Hydrogen and oxygen atoms in water molecule form polar covalent bonds formed through hydrogen bonding. Oxygen has three isotopes to remember ; H2160, H2180 and H2170. Sea water for example has approximately 99% H2160 and less than 0.5% H2180.

Evaporating waters releases more H2160 to the atmosphere than H2180.In areas where polar ice takes time to melt, the oceans are contantly depleted of H2160 until it melts to return to the water bodies and maintain balance.This shows that the water molecules that exists in greatest abundance is H2160.

A positively charged non-metal ball A is placed near metal ball B. Prove that if the charge on B is positive but of small magnit
nordsb [41]

Answer:

D

Explanation:

Ball A is a non positively charged non metal while ball B is metal ball.

Given: The ball B positive charge of small magnitude

To prove: Balls will attract each other

IN this condition because of induction negative charges on the sphere B move to the side closer to sphere A,(induction charging) while the positive charges move to the side further away from sphere A. The polarization of charge on B will cause a greater attractive force than the repulsion of the like charges.

Hence the correct answer will be D .

An object is pulled northward with a force of 10 n and southward with a force of 15 n. the magnitude of the net force on the obj
Anastaziya [24]

The correct option is (b) 5n

As a result, there is a net downward force of 5N operating on the object.

The resultant force is the force that results from adding the vector sums of all the forces operating on an item. The combined action of all the acting forces on the object produces the same effect as the resulting force. When determining the resulting force, the direction of the forces must be taken into account.

Given;

The northward force is Fn = 10N

The southward force is Fs = 15N

Required;

The net force on the mobile phone is Fnet = ?N

The object's weight exerts downward pressure, and upward resistance exerts upward pressure. The vector sum of these two forces will be the net force.

Fnet = Fs - Fn (Considering the direction downward as positive)

Fnet= 15N - 10N

Fnet = 5N

As a result, there is a net downward force of 5 N operating on the object.
