Answer:

The inductance of the inductor is 3.2 mH.

Explanation:

Given that,

Current = 0.560 A

Angular frequency = 280 rad/s

Voltage = 0.500 V

We need to calculate the inductance

Using formula of inductance

L=\dfrac{V_{max}}{I_{max}\times\omega}

Put the value into the formula

L=\dfrac{0.500}{0.560\times280}

L=0.00319=3.2\ mH

Hence, The inductance of the inductor is 3.2 mH.

A spherical bowling ball with mass m = 4.1 kg and radius R = 0.117 m is thrown down the lane with an initial speed of v = 8.9 m/
weqwewe [10]

Answer:Given mass = 4.1kg

Radius = 0.0117m

Velocity V = 8.4m/s

Coefficient of friction = 0.25

Explanation: Below is an attached solution to the problem stated above.

1. The angular acceleration is equal to 524rad/s^2

2. The linear acceleration is equal to 2.45m/s^2

3.the time it takes the ball to begin rolling = 0.98s

4. The distance the ball slides before it begins to roll = 7.05m

Answer:

A leaf is falling from the tree.

Explanation:

If motion is in only one direction(x-direction) then it is know as one directional motion.

If motion is in only two direction (x and y directions) then it is know as two directional motion.

If motion is in only three direction (x , y and z directions) then it is know as three directional motion.

A bird is flying in the air -This is three directional motion.

A leaf is falling from the tree - This is two directional motion.

A train is running on track - This is  one directional motion

A lady is crawling  on the surface of the ball - This is three directional motion.

Therefore the answer is  ---

A leaf is falling from the tree.

If a train going 60 m/s hits the brakes, and it takes the train 85 seconds to stop, what is
Anvisha [2.4K]

Question :-

  • If a Train going with 60 m/s Speed hits the Brakes, and takes 85 sec to stop. What is the Acceleration of the Train ?

Answer :-

  • Acceleration of Train is 0.70 m/s² .

Explanation :-

As per the provided information in the given question, we have been given that the Speed of the Train is 60 m/s . Time taken to stop the Train is 85 sec . And, we have been asked to calculate the Acceleration of the Train .

For calculating the Acceleration , we will use the Formula :-

\bigstar \:  \:  \:  \boxed { \sf{ \: Acceleration \:  =  \:  \dfrac{v \:  -  \: u}{t} \:  }} \\

Where ,

  • V denotes to Final Velocity .
  • U denotes to Initial Velocity .
  • T denotes to Time Taken .

Therefore , by Substituting the given values in the above Formula :-

\dag \:  \:  \:  \:  \sf{Acceleration \:  =  \:  \dfrac{Final  \: Velocity \:  -  \: Initial \: Velocity}{Time} } \\

\longmapsto \:  \:  \: \sf{Acceleration \:  =  \:  \dfrac{0 \:  -  \: 60}{85} } \\

\longmapsto \:  \:  \: \sf{Acceleration \:  =  \:  \dfrac{60}{85} } \\

\longmapsto \:  \:  \: \textbf {\textsf {Acceleration \:  =  \: 0.70 }}

Hence :-

  • Acceleration = 0.70 m/s² .
