Answer:

Current in the capacitor will be equal to 0.01 A      

Explanation:

Capacitance of the capacitor C=20nF=20\times 10^{-9}F

Capacitor voltage is change to 5 volt

So change in capacitor voltage dV=5volt

Time taken to change in capacitor voltage dt=10\mu sec=10^{-5}sec

Current in the capacitor is equal to

i=C\frac{dV}{dt}=20\times 10^{-9}\times \frac{5}{10^{-5}}=0.01A

So current in the capacitor will be equal to 0.01 A

tatuchka [14]

Answer:

v = 0.5 [m/s]

Explanation:

In order to determine the speed in such a time interval, we must calculate the slope between the last two positions.

The slope of a line is determined by the following mathematical expression.

P₂ = point 2 = (12,12) = (x₂,y₂)

P₁ = Point 1 = (6,9) = (x₁,y₁)

In this specific case, we must see that in the x-axis we have time, and on the y-axis, we have the space axis.

Now using the slope:

m =\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\m = \frac{12-9}{12-6}\\m = 0.5

This slope is equal to the speed (velocity)

v = 0.5 [m/s]

How is velocity ratio of wheel and axle calculated​
Rudiy27

Answer:

VR = \frac{Radius of the wheel}{Radius of the axle}

Explanation:

Velocity ratio (VR) of a machine is a term that compares the distance moved by effort put into the machine to the distance moved by the load.

A wheel and axle is a device for lifting of a load through a height. It is made up of two circular parts called wheel and axle. Its velocity ratio (VR) can be determined by:

VR = \frac{Radius of the wheel}{Radius of the axle}

For a practical wheel and axle, the diameter of the wheel is greater than the diameter of the axle.
