A window washer who does not want to change his position will want the forces acting on him to be ____________. a. balanced
b. large
c. small
d. unbalanced

Answers

Before solving this question first we have to understand Newton's  first law of motion

As per Newton's first law it is impossible to change the state of rest or uniform motion along a straight line unless and until it is compelled by some external unbalanced forces.

Everybody tends to oppose the change of state of rest due to  their inertia.A book present on a table pushes the table with its weight in vertically downward direction while table applies same amount of force on the book in vertically upward direction.The net force acting on each  body is zero.So the book will show no motion.

Actually  balanced force have no role in changing the state of rest of the body. Only unbalanced force will cause the body to move.

Hence the washer who does not want to change his position will want the force acting on him to be [balanced ].
a. balanced is the answer

When a contest between two candidates is very close, people area. more likely to vote.
b. less likely to vote.
c. unlikely to notice.`
d. more likely to join a political party.

Answers

When a contest between two candidates is veryclose, people are less likely to vote and in return, the candidate with alesser support and is expected not to win may win instead. Because people willbe expecting that the two contending and strong candidates will win anyway becausemany people are expected to vote them. So other people will choose to vote thelesser candidate, trying to even the probability of the strong winning streaksof the other candidates.

Which form of energy is stored chemical energy and example of? a
Kinetic energy

b
Potential energy

c
Gravitational energy

d
Powered energy Which form of energy is stored chemical energy and example of? (2 points)

a
Kinetic energy

b
Potential energy

c
Gravitational energy

d
Powered energy

Answers

Answer:

B

Explanation:

Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.

Two objects, one with a mass of 2 kg and one with a mass of 3 kg are attracted to each other by a gravitational force. If the force on one mass is 4 N, what is the force on the other mass?

Answers

By Newton's 3rd law: That for every action there is an equal and opposite reaction.

So if force on one mass is 4N, then the force on the other mass is -4N.

A rock containing valuable minerals that can be mined is called A. An inorganic compound
B. An igneous rock
C. An ore
D. An organic compound

Answers

A rock containing valuable minerals that can be mined is called an ore. The correct option is C.

What is an ore?

Ore is a deposit of one or more valuable minerals present inside the Earth's crust.

Metals essential to industry and trade, such as copper, gold, and iron, are found in the most valuable ore deposits. Copper ore is mined for a number of industrialapplications.

Ore is natural rock or sediment that contains one or more valuable minerals, usually metals, and can be mined, treated, and sold for a profit.

Mining extracts ore from the Earth, which is then treated or refined, often through smelting, to extract valuable metals or minerals.

Crushing the rock is the first step in extractingore from it. Heap leaching, flotation, or smelting are methods for extracting ore from rock.

Thus, the correct option is C.
