Answer:

I=0.1          R=2500

Explanation:

Resistance

R=\frac{V^{2} x}{P} \\=\frac{250^{2} }{25} \\=2500

Current

I=\frac{250}{2500} \\=0.1

the line on the position time graph show the velocites of different vehicles which line represents a vehicle moving at constant
Oksi-84 [34.3K]

For some mysterious reason, we can't see the graph.

On a position/time graph, constant velocity is represented by a <em>straight line</em>.  Depending on the velocity, the line may be sloping up, sloping down, or horizontal.  The only thing the line on the graph <u><em>CAN't</em></u> be is vertical.

With the intensity at about half of maximum, how does the current change when you increase the frequency of the light?
PIT_PIT [208]

Answer:

Increase

Explanation:

Energy  of  given as follows

E = h f

Where f is the frequency of incident light

when high frequency light falls then it will increase the number of produce photon and that increase in number of photon will lead to increase in the number of electron.When number of electron will increase it mean that current will also increase.

So we can say that when frequency increase then current will increase.
