You have a 1.8m long copper wire. You want to make an N-turn current loop that generates a 2.0mT magnetic field at the center wh

NikAS [45]

Answer:

The diameter is 0.022m.

Explanation:

The magnetic field $B$ at the center of the coil is given by

(1). $B = \dfrac{\mu_0 NI}{d}$

where $\mu_0 = 1.26*10^{-6} m\:kg\:s^{-2} A^{-2}$ is the magnetic constant, $I$ is the current, $N$ number of coils, and $d$ is the diameter of the coil.

Now, if we call $L$ the length of the wire, then it must be true that

$\pi dN = L$ (this says $N$ coil circumferences ( $c=\pi d$ ) fit into $L$ )

$\therefore N = \dfrac{L}{\pi d }$

putting this into equation (1) we get:

$B = \dfrac{\mu_0 IL }{\pi d^2}$

solve for $d:$

$\boxed{d = \sqrt{\dfrac{\mu_0I L }{\pi B} }}$

putting in the numerical values

$\mu_0 = 1.26*10^{-6} m\:kg\:s^{-2} A^{-2}$

$I =1.3A$

$L= 1.8m$

$B =2.0*10^{-3}T$

we get:

$d = \sqrt{\dfrac{(1.26*10^{-6})(1.3) *1.8 }{\pi (2.0*10^{-3})} }$

$\boxed{d = 0.022m}$

Design a diagram, sketch, or other model to show changes in the nucleus of an atom during nuclear fission and fusion. Include a

Drupady [299]

Explanation:

Inside the sun, fusion reactions take place at very high temperatures and enormous gravitational pressures

The foundation of nuclear energy is harnessing the power of atoms. Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. They are opposing processes, and therefore very different.

The word fission means "a splitting or breaking up into parts" (Merriam-Webster Online, www.m-w.com). Nuclear fission releases heat energy by splitting atoms. The surprising discovery that it was possible to make a nucleus divide was based on Albert Einstein’s prediction that mass could be changed into energy. In 1939, scientist began experiments, and one year later Enrico Fermi built the first nuclear reactor.

A fish is hooked on a line that is wound around the spool of a fishing reel. The reel has a mass of 652 g and a diameter of 10 c

iren2701 [21]

The magnitude of the force exerted by the fish is 3,052.5 N.

The given parameters;

mass of the reel, m = 652 g = 0.652 kg

diameter of the reel, d = 10 cm

radius of the reel, r= 5 cm = 0.05 m

time of motion, t = 5 s

angular speed of the reel, ω = 306 rad/s

According to Newton's third law, the force exerted by the reel is equal in magnitude to the force fish exerted on the reel.

The centripetal force of the reel = force exerted by the fish

$F_c = m\omega^2 r\\\\F_c = 0.652 \times (306)^2 \times 0.05\\\\F_c = 3,052.5 \ N$

Thus, the magnitude of the force exerted by the fish is 3,052.5 N.
