A) An independent variable.
B) A proportionality constant
C) The y-intercept

D) A numerical constant

2. In terms of fundamental SI units,a newton is equal to

1. A) 1 kg*m2/s2

2. B) 1 kg*m/s

3. C) 1 kg*m/s2

4. D) none of the above

3. A hypothesis concerned with a specific phenomenon is found to be acceptable through many experiments over a long period of time. This tested hypothesis usually becomes known as a?

1. A) Scientific law

2. B) Model

3. C) Theory

4. D) Scientific principle

4. The fundamental property with the SI unit of mole is

1. A) Temperature

2. B) Amount of a substance

3. C) Mol

4. D) Ss

Answer 1

1. F=-kx+f

k= slope of the graph

So, Option A) An independent is the answer.

2.

1 Newton = Force = mass x acceleration =1 kg*m/s2

So Option C)  1 kg*m/s2 is answer

3.

A hypothesis concerned with a specific phenomenon is found to be acceptable through many experiments over a long period of time. This tested hypothesis usually becomes known as a Scientific law.

Option A

4.

Mole is SI unit of amount of substance.

Option B
