Real-world examples of power

Paha777 [63]

By definition, power is the amount of energy consumed (or produced) in a second. (or more precisely, it is the rate of change in energy).
so anything which uses energy in a known time period can be labeled with a power rating.

an example for power could be a nuclear plant; traditional nuclear plants produce somewhat close to 1 giga watts (which means 1 giga joules in a second)

Photon Lighting Company determines that the supply and demand functions for its most popular lamp are as follows: S(p) = 400 - 4

torisob [31]

Answer: The correct answer is (C).

Explanation:

Supply function:

$S(p)=400-4p+0.00002p^4$

Demand function:

$D(p)=2800-0.0012p^3$

S(p)=D(p), price for which supply is equal to demand:

$S(p)=D(p)=400-4p+0.00002p^4=2800-0.0012p^3$

After solving this above equation graphically, we will get the values of p.

1) p =96.236

2) p=( -118.258)

We will reject the negative value of p.

So, the value of p that price for which the supply equals the demand is $ 96.236 $\approx$ $96.24. Hence, the correct answer is option (C).

a conducting rod whose length is 25 cm is placed on a u-shaped metal wire that has a resistance of 8.0 ω . the wire and the rod

andreyandreev [35.5K]

Answer:

The current is $I = 1 A$

The direction is anti-clockwise

Explanation:

The diagram for this question is shown on the first uploaded image

From the question we are told that

the length of the conducting rod is $L = 25 \ cm = \frac{25}{100} = 2.5 \ m$

The resistance is $R = 8 \Omega$

The magnetic field is $B = 0.40\ T$

The speed of the rod is $v = 6.0 m/s$

The emf induced is

$\epsilon = BLv$

substituting values we have

$\epsilon = 0.40 * 2.5 * 8$

$\epsilon = 8V$

From ohm law the induced current would be

$I = \frac{\epsilon}{R }$

substituting values we have

$I = \frac{8}{8 }$

$I = 1 A$

The direction anticlockwise this because according to lenze law the current due to change in magnetic field will act in the opposite direction of the force causing the magnetic field to change
