Why is the unit of temperature is called derived unit​

Physics
1 answer:
Vadim26 [7]3 years ago
3 0

Explanation:

The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.

Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units

if you have a mass of 55 kg and you are standing 3 meters away from your car, which has a mass of 1234 kg, how strong is the for
bagirrra123 [75]

Gravitational force between two masses is given by formula

F = \frac{Gm_1m_2}{r^2}

here we know that

m_1 = 55 kg

m_2 = 1234 kg

r = 3 m

G = 6.67 \times 10^{-11} Nm^2/kg^2

now from the above equation we will have

F = \frac{(6.67 \times 10^{-11})(55)(1234)}{3^2}

F = 5.03 \times 10^{-7}N

so above is the gravitational force between car and the person

What is a scalar? APEX
lianna [129]

Answer:

C. A quantity that does not indicate direction.

Explanation:

There are two types of quantities in physics:

- Scalars: a scalar quantity is a quantity which has only a magnitude, and not a direction.

Examples of scalar quantities are: mass, temperature, time, distance, speed...

- Vectors: a vector quantity is a quantity having both a magnitude and a direction.

Examples of vector quantities are: velocity, displacement, force, acceleration...

Therefore, for the question in the problem:

<em>What is a scalar?</em>

The correct answer is:

C. A quantity that does not indicate direction.
