The current in the coil is 297 A

Explanation:

The magnetic field of a circular coil carrying a current is given by

$B=\frac{\mu_0 NI}{2R}$

where

$\mu_0 =4\pi \cdot 10^{-7} Tm/A$ is the vacuum permeability

N is the number of turns in the coil

I is the current in the coil

R is the radius of the coil

For the coil in this problem, we have:

$B=14\cdot 10^{-3} T$

R = 20 cm = 0.20 m

N = 15

Solving the equation for I, we find the current in the coil:

$I=\frac{2BR}{\mu_0 N}=\frac{2(14\cdot 10^{-3})(0.20)}{(4\pi \cdot 10^{-7})(15)}=297 A$

To lift a load of 100 kg a distance of 1 m an effort of 25 kg must be applied over an inclined plane of length 4 m. What must be

andreyandreev [35.5K]

Work = force * distance.
We must produce twice as much energy as we are lifting the weight twice as high.
But we are not increasing the force so we must increase the length of the ramp ( distance ) instead.
The new length will be twice as great as the previous length.
So 8 metres is required.

25 kg * 8 m = work = 100 kg * 2 m

A person is lying on a diving board 3.50 m above the surface of the water in a swimming pool. She looks at a penny that is on th

sergij07 [2.7K]

Answer:

1.995 m

Explanation:

Distance of penny as seen by the person = 5 m

Height of person from water surface = 3.50 m

Apparent depth of penny = 5 - 3.50 = 1.5 m

refractive index of water, n = 1.33

real depth / apparent depth = n

real depth = 1.33 x 1.5 = 1.995 m

Thus, the actual depth of water at that point is 1.995 m.

Two 60 cm parallel disks are separated by 40 cm and are aligned directly on top of each other. Both disks are black surfaces wit

Crazy boy [7]

Answer:

775.48 W

Explanation:

given,

diameter of disk = 0.6 cm

length of the disk = 0.4 m

T₁ = 450 K T₂ = 450 K T₃ = 300 K

$\dfrac{d}{r_1}=\dfrac{0.4}{0.3}$ = 1.33

now,

the value of view factor (F₁₂)corresponding to 1.33

F₁₂ = 0.265

F₁₃ = 1 - 0.265 = 0.735

now,

net rate of radiation heat transfer from the disk to the environment:

$=\dot{Q_{1-3}+Q_{2-3}} = 2 \dot{Q_{1-3}}$

= 2 F₁₃ A₁ σ (T₁⁴ - T₃⁴)

= 2 x 0.735 x π x (0.3)² x (5.67 x 10⁻⁸ W/m²) (450⁴ - 300⁴)

= 775.48 W

Net radiation heat transfer from the disks to the environment = 775.48 W

What tools enable people to connect and exchange ideas

aleksklad [387]

Answer:

The answer is: "Social Media tools"

Explanation:

"Social Media tools" are <u>very popular tools being used by the modern generation these days.</u> They come in different types according to their usage (Listening Platforms, Publishing Platforms and Competitive Analysis Platforms). Examples of these are: <em>Hootsuite, Buffer, Oktopost, Canva, Google Trends, BuzzSumo, etc.</em>

These tools allow people to interact with one another. People can published the information they want to share and distribute this information to other people. Marketers also use these tools in order to aid them regarding online businesses and the like. Some social media tools are available for free while others have to be purchased.

Thus, this explains the answer.
