What force causes a moving object to move in a curved or circular path?

Answers

Answer 1

Answer: THE UNBALANCED FORCE THAT CAUSES OBJECTS TO MOVE IN A CIRCULAR PATH IS CALLED A CENTRIPETAL FORCE. GRAVITY PROVIDES THE CENTRIPETAL FORCE THAT KEEPS OBJECTS IN ORBIT. THE WORD CENTRIPETAL MEANS "TOWARD THE CENTER

A block initially at rest on a horizontal, frictionless surface is accelerated by a constant horizontal force of 5 newtons. if 15 joules of work is done on the bock by this force, the kinetic energy of the block increases by

Answers

Answer: The kinetic energy of the block increases by 15 Joules.

Explanation:

Work done is defined as the product of force and displacement of the object.

Mathematically,

$W=F.s$

where,

W =work done

F = force

s = Displacement

Kinetic energy is defined as the energy which is possessed by the virtue of object's motion.

In the question, it is given that work done on block is 15 Joules and we need to find the change in kinetic energy of the block.

We know that,

Work done on the object = Change in kinetic energy of the object

Thus, Kinetic energy is increased by 15 Joules.

The kinetic energy depends on the work done by the applied force. The kinetic energy of the block increases by 15 J.

What is kinetic energy?

The energy possessed by an object by its motion is known as the object's kinetic energy.

Given data-

The magnitude of the constant horizontal force is F = 5 N.

The work done on the block is, W = 15 J.

As per the work-energy theorem, the work done by the applied force is equal to the change in kinetic energy.

Then,

W = ΔKE

Solving as

15 = ΔKE

ΔKE = 15 J

Thus, we can conclude that the block's kinetic energy increases by 15 J.

How do elements change as you move down a column in a periodic table? a.the atomic radius decreases b.the number of protons decreases c.the atomic mass decreases d.the electronegativity decreases

Answers

Answer: Option (d) is the correct answer.

Explanation:

Electronegativity is defined as the ability of an atom to gain electrons in order to become stable.

When we move downwards in a group then there will be increase in size of atom. As a result, atomic radius will also increase.

Also, due to increase in size number of electrons will increase and hence, number of protons will also increase. Therefore, atomic mass will also increase.

Thus, we can conclude that elements change as you move down a column in a periodic table as the electronegativity decreases.

As you move down a column :
* the atomic number increases
* the number of protims increases
* the atomic mass increases
* the electronegativity decreases

A reaction in which small nuclei combine to form a heavier nucleus is called ____. a. fission c. background radiation b. a chemical reaction d. fusion

Answers

The correct answer is D) fusion. In fact, nuclear fusion occurs when two (or more) small nuclei combine to form a heavier nucleus. In the process, a large amount of energy is released, according to Einstein's formula $E=mc^2$ , where m is the mass converted into energy in the reaction. An example of nuclear fusion is the fusion of two nuclei of hydrogen into a nucleus of helium-4.

What conditions are typcial of the soil the deeper we dig into it?

Answers

When we first dig into soil, it's nice and soft.( Depending on what soil it is; usually topsoil)

But when we go deeper into it, there are rocks and the soil is harder. There is bedrock at the bottom, subsoil in the middle, and topsoil at the top, which is where we walk.

What parts of an atom can change during a nuclear reaction that cannot change during a chemical reaction? Question 15 options: A. The number of protons and neutrons B. The number of electrons only C. The number of protons and electrons D. The number of neutrons and electrons

Answers

Answer;

B. the number of protons and neutrons

Explanation;

Nuclear reactions involve a change in the nucleus of an atom, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
Therefore the parts of an atom that can change during a nuclear reaction but can not change during a chemical reaction is the number of protons and neutrons that are found in the nucleus.

Neutrons and protons cannot be removed from nucleus from chemical reactions because they are strongly held together but nuclear reactions are strong enough to separate them. Hence option A is correct.
