A solid, horizontal cylinder of mass 18.0 kg and radius 1.70.0 m rotates with an angular speed of 40 rad/s about a fixed vertica
Radda [10]

Answer:39.88 rad/s

Explanation:

Given

mass of cylinder m_1=18 kg

radius R=1.7 m

angular speed \omega =40rad/s

mass of m_2=0.8 kg dropped at r=0.3 m from center

let \omega _2 be the final angular velocity of cylinder

Conserving Angular momentum

L_1=L_2

\left ( \frac{m_1R^2}{2}\right )\omega =\left ( \frac{m_1R^2}{2}+m_2r^2\right )\omega _2

\left ( \frac{18\cdot 1.7^2}{2}\right )\cdot 40=\left ( \frac{18\cdot 1.7^2}{2}+0.8\cdot 0.3^2\right )\omega _2

26.01\times 40=26.082\times \omega _2

\omega _2=39.88 rad/s

My Notes A flat loop of wire consisting of a single turn of cross-sectional area 7.80 cm2 is perpendicular to a magnetic field t
Nastasia [14]

Answer:

0.00158 A

Explanation:

A = Area of loop = 7.8 cm²

B_f = Final magnetic field = 3.2 T

B_i = Initial magnetic field = 0.5 T

R = Resitance = 1.3\ \Omega

The emf is given by

E=\frac{(B_f-B_i)A}{t}\\\Rightarrow E=\frac{(3.2-0.5)\times 7.8\times 10^{-4}}{1.02}\\\Rightarrow E=0.00206\ V

The current is given by

I=\frac{E}{R}\\\Rightarrow I=\frac{0.00206}{1.3}\\\Rightarrow I=0.00158\ A

The resulting induced current in the loop is 0.00158 A

mylen [45]

Answer:

2 minutes or 120 seconds

Explanation:

The answer is 2 minutes or 120 seconds because 36 km is 36000 m and 36000 divided by 300 is 120, so the answer is 120 seconds, and converted to 2 minutes. Hope it helps!
