The speed of the stopper is 4.95 m/s, while the centripetal force on the stopper and the tension in the string is 3.42N each.

The mass of the stopper is 0.13 Kg, the length of the string to which it is attached is 0.93 m. The stopper swung and made one revolution in 1.18 seconds, so the time period of revolution of the stopper is 1.18 seconds.

The relation between the time period and the angular speed is,

T = 2π/W

W is angular speed and T is the time period of revolution.

Putting values,

1.18 = 2π/W

W = 5.32 rad/s.

The speed of the stopper can be found as,

v = rW

r is the length of the string,

V = 4.95 m/s.

The centripetal force on the stopper is given by,

F = MV²/r

Putting values,

F = 0.13 x 4.95 x 4.95/0.93

F = 3.42 N.

The tension in the string will be equal to the centripetal force on the stopper, so, the tension is 3.

42 N.

20. The speed of Light is 3.0 x 108 m/s. Blue Light has a frequency of 6.11 x 1014 Hz. What is its wavelength?
Sladkaya [172]

Answer:

4.91 x 10⁻⁷ m

Explanation:

the applicable formula is

v = fλ

where

v = velocity (i.e speed) = given as 3.0 x 10⁸ m/s

f = frequency = given asw 6.11 x 10¹⁴

λ = wavelength

if we rearrange the equation and substitute the values given above,

v = fλ

λ = v/f  

= 3.0 x 10⁸ / 6.11 x 10¹⁴

= 4.91 x 10⁻⁷ m

The heating system in Jeff and Tony's new home takes cool air and passes it through the heat source using a fan or blower. What
-BARSIC- [3]

If it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.

<h3>What is heat transfer by convection?</h3>

Convection is the transfer of heat from one place to another due to the movement of fluid.

During heat transfer by convection, cold air replaces hot risen air.

Thus, if it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.

A :-) a = v^2 by r
Given - radius = 25 m
velocity = 10 m/s
Solution -
a = v^2 by r
a = ( 10 )^2 by 25
a = 100 by 25
( cut 25 and 100 because 25 x 4 = 100 )
a = 4 m/s^2

.:. The centripetal acceleration of the car
= 4 m/s^2.
