Answer:

The term that refers the rate change of motion is acceleration.

Explanation:

The rate at which the motion changes is called as the acceleration. It is a vector quantity with the SI unit meters. There is device to measure the acceleration called as accelerometer. The acceleration is also affected by the increase and the decrease of the force and mass. It is directly proportional to it. The acceleration increases with force, but found to be decreasing with mass. It can be calculated by taking the product of displacement by time.

12. The diameter of a circle is 2.42m. Calculate its<br>area in proper significant figure

Sever21 [200]

Answer:

A = 4.6 [m²]

Explanation:

The area of a circle can be calculated by means of the following equation.

$A=\frac{\pi }{4} *D^{2}$

where:

A = area [m²]

D = diameter = 2.42 [m]

Now replacing:

$A=\frac{\pi }{4} *(2.42)^{2} \\A = 4.6 [m^{2} ]$

La) What is meant by the term Basic Quantities.

castortr0y [4]

Answer:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

Mass, denoted by the symbol 'm', with S.I. unit 'kg'
Length, denoted by symbol 'l', with S.I. unit 'm'
Time, denoted by symbol 't', with S.I. unit 's'
Current, denoted by 'I', with S.I. unit 's' 'A'
Temperature, denoted by 'T', with S.I. unit 'K'
Amount of substance, denoted by 'n', with S.I. unit 'mol'
Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

A basic quantity is chosen arbitrarily.

The KEOM tower across the street from West is approx. 155 meters high

blondinia [14]

You told your insane friend that it will take the book 5.6 s to get to the ground.

From the question given above, the following data were obtained:

Height (H) = 155 m

<u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²

The time taken for the book to get to ground can be obtained as follow:

155 = ½ × 10 × t²

155 = 5 × t²

<h3>Divide both side by 5</h3>

$t^{2} = \frac{155}{5}\\\\$

t² = 31

<h3>Take the square root of both side </h3>

$t = \sqrt{31}$

Thus, the time taken for the book to get to the ground is 5.6 s

Hence, you told your insane friend that it will take the book 5.6 s to get to the ground.
