There is no requirement of Time period if u r given the rest data.
Centripetal force(F) = mv²/r.
where m is mass of body , v is the speed , and r is the radius of the path.
=> F =( 0.30×0.50×0.50)/0.10 = 0.75 m/s².
Its direction is radially inwards.
Hope it helps!!!

You tie the loose end of a 0.1 kg yo-yo string to your finger and then release the yo-yo so that it spins down toward the ground
Nikitich [7]

Answer:

The answer is "5.06 \times 10^{-6} \ kg \ m^2"

Explanation:

\to E_1=0..............(i)\\\\\to E_2= \frac{mV^2}{2} +\frac{Iw^2}{2} - mgh.............(ii)\\\\ \Delta E=0\\\\\to mgh= \frac{mV^2}{2} +\frac{Iw^2}{2} \\\\ \to 2 \ mgh=  mV^2 +Iw^2\\\\ \to 2 \ mgh- mV^2 =Iw^2\\\\ \to  m(2gh- V^2) =Iw^2\\\\ \to I= \frac{m(2gh- V^2)}{w^2}

       = 5.06 \times 10^{-6} \ kg \ m^2

An athlete runs at a constant velocity of 5.2 m/s. What is the velocity of the athlete relative to the ground?
dimulka [17.4K]

The relative velocity of the athlete relative to the ground is 5.2 m/s

The given parameters;

constant velocity of the athlete, V = 5.2 m/s

let the velocity of the ground = Vg = 0

The relative velocity concept helps us to determine the velocity of a moving object relative to a stationary observer.

The athlete is the moving object in this question while the ground is stationary.

The relative velocity of the athlete relative to the ground is calculated as follows;

V/V_g = V - V_g  = 5.2 - 0 = 5.2  \ m/s

Thus, the relative velocity of the athlete relative to the ground is 5.2 m/s

Calculate the total resistance in a parallel circuit made up of resistances of 2, 3, and 4.
Tamiku [17]

Answer:

<em><u>0</u></em><em><u>.</u></em><em><u>9</u></em><em><u>1</u></em>

Explanation:

as equivalence resistance can be found out using the

1/Req = 1/r1 +1/r2 +1/r3......

now, 1/req= 1/2+1/3+1/4

=6/12+4/12+3/12

=13/12

i.e, req =12/13 =0.91

Help!! I’ll give brainliest!! Which person will hear the highest pitch?
boyakko [2]

Answer: person C.


Explanation:


1) The frequency of the sound wave is perceived or detected as the pitch of the sound.


And the higher the frequency the the higher the pitch.


2) When a sound source is in motion there is an apparent change in the pitch perceived. This is the Doppler effect, which is defined as the change in the perception of the pitch in virtue of the relative motion between the listener and the emitter of the sound.


If the source of the sound is moving toward the listener, the pitch will be higher that if the sound is at rest. If the source of the sound is moving away from the listener, the pitch will be lower.


That is because the the motion of the emitter increases (or decreases, depending on whether the emitter is moving toward or away the listener) the speed of the sound waves and they arrive more frequently (or less frequently).


Then, since the sound is emitted by the motorbike and it is moving toward the person C, he will hear the highest pitch.
