A long, thin solenoid has 950 turns per meter and radius 3.00 cm. The current in the solenoid is increasing at a uniform rate of

REY [17]

Answer:

Part a)

$E = 0.188 \times 10^{-3} N/CPart b)[tex]E = 0.376 \times 10^{-3}$ N/C

Explanation:

As we know that the magnetic field near the center of the solenoid is given as

$B = \mu_0 ni$

Also we know by equation of Faraday's law

EMF induced in the closed loop will be equal to rate of change in magnetic flux

so we have

$EMF = A\frac{dB}{dt}$

so we have

$\int E. dL = \pi r^2 (\mu_0 n \frac{di}{dt})$

$E. (2\pi r) = \pi r^2 (\mu_0 n \frac{di}{dt})$

$E = \frac{\mu_0 n r}{2} \frac{di}{dt}$

Part a)

At r = 0.500 cm

we have

$E = \frac{4\pi \times 10^{-7} (950) (0.500 \times 10^{-2})}{2}(63)$

$E = 0.188 \times 10^{-3} N/C$

Part b)

At r = 1.00 cm

we have

$E = \frac{4\pi \times 10^{-7} (950) (1.00 \times 10^{-2})}{2}(63)$

$E = 0.376 \times 10^{-3}$ N/C

The arrival time of an elevator in a 12-story dormitory is equally likely at any time range during the next 5.5 minutes. (a) Cal

Bumek [7]

Answer:

(a). 2.8 minutes.

(b). 0.4732

Explanation:

Without mincing words, let's dive straight into the solution to the question.

So, for the part (a), the expected arrival time can be calculated as given below.

The distribution falls between the ranges of 0(lower boundary) to 5.5minutes(upper boundary).

Therefore, the expected time = (0 + 5.5)÷ 2 = 2.75 minutes = 2.8 minutes(to 2 decimal places).

(b). The probability that an elevator arrives in less than 2.6 minutes can be calculated as given below;

Recall: We have that the upper boundary = 0 and the lower boundary = 5.5 minutes for the distribution. Also, the upper limit is equal to 2.6 minutes and the lower limits = 0 minutes.

Therefore, 1/ (5.5 - 0) = 1/5.5 = 0.182.

Therefore, the probability that an elevator arrives in less than 2.6 minutes = 0.182 ( 2.6 - 0).

The probability that an elevator arrives in less than 2.6 minutes = ( 0.182 × 2.6).

The probability that an elevator arrives in less than 2.6 minutes = 0.4732.

If the core of jupiter is 30,000 celcius and it is five times hotter than the sun, what's the temperature of the surface of the

VMariaS [17]

Let, the temperature of Sun's surface = c

So, 5c = 30, 000
c = 30,000 / 5
c = 6,000

In short, Your Answer would be 6000

Hope this helps!
