Answer:
<u>Given </u><u>information:</u><u>-</u>
- Radius of the circular track is <u>636 m</u>
- The time elapsed in the journey is <u>1.5 min or 90 s</u>
- The distance traveled by the cyclist is semi circumference of the circle = <u>πr</u>
The displacement of the cyclist will be shortest distance from his initial to final positions which is nothing but diameter of the circle = 2r
<u>We know that,</u>
- Speed of the cyclist is 22.18 m/s
- <u>Velocity of the cyclist</u> is 14.13 m/s
Thank You :)
Answer:
Inertia
Explanation:
The term for the tendency is inertia.
<em>The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion. </em>
A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.
Answer:
1.45
Explanation:
Refractive index of the liquid is given as;
Refractive index =
But,
speed =
Since a certain light of specific wavelength was used during the same time, let the time be represented by t.
So that;
speed of light in vacuum =
speed of light in the liquid =
Refractive index = ÷
= x
Refractive index =
= 1.4536
= 1.45
The refractive index of the liquid is 1.45.
