Twin skaters approach each other with identical speeds. Then, the skaters lock hands and spin. Calculate their final angular vel

kherson [118]

Answer:

$\omega=3.135rad/s$

Explanation:

From the question we are told that:

initial Speed $V_1=2.50$

Mass $m=70.0kg$

Center of mass $d=0.0.800m\$

Generally the equation for angular velocity is is mathematically given by

$\omega=\frac{v}{r}\\\\\omega=\frac{2.50}{0.0800}$

$\omega=3.135rad/s$

A coil formed by wrapping 65 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the

Fiesta28 [93]

Answer:

377 m

Explanation:

number of turns, N = 65

θ = 36°

B1 = 200 micro Tesla

B2 = 600 micro tesla

t = 0.4 s

induced emf, e = 80 mV

Let a be the side of the square coil.

$e=\frac{d\phi }{dt}=NA\frac{dB}{dt}\times Sinθ$

$0.080=\frac{65\times a^{2}\times Sin36\times\left ( 600 - 200 \right )\times 10^{-6}}{0.4}$

$0.080=0.038a^{2}$

a = 1.45 m

Total length of the wire, L = N x 4a = 65 x 4 x 1.45 = 377 m

Thus, the length of the wire is 377 m.
