A flat, 101 turn current‑carrying loop is immersed in a uniform magnetic field. The area of the loop is 5.61×10−4 m2, and the an

gle between its magnetic dipole moment and the field is 48.9∘. Find the strength of the magnetic field that causes a torque of 2.75×10−5 N⋅m to act on the loop when a current of 0.00339 A flows in it.

Answer:

0.2 tesla

Explanation:

Number of turn, N = 101

Area, A = 5.61 x 10^-4 m^2

angle between the magnetic moment and magnetic field, θ = 48.9°

Torque, τ = 2.75 x 10^-5 Nm

Current, i = 0.00339 A

Let the magnetic field strength is B.

The formula for the torque is given by

\tau = M \times B \times Sin\theta

where, M is the magnetic moment

M = N x i x A = 101 x 0.00339 x 5.61 x 10^-4 = 1.92 x 10^-4 Am^2

By substitute the values

2.75 x 10^-5 = 1.92 x 10^-4 x B x Sin 48.9°

B = 0.189 Tesla

B  = 0.2 Tesla

This is true. Gravity is constantly pulling on anything and everything (even light!), no matter how far away it is from another object.

A rocket has landed on Planet X, which has half the radius of Earth. An astronaut onboard the rocket weighs twice as much on Pla
Burka [1]

Explanation:

Let acceleration due to Gravity for a planet is given by:

g_X=GM/R^2

Here,g_X = 2g

Escape velocity is given by:

v =\sqrt{ \frac{2GM} {R}} = \sqrt{2aR}

Here, R=R_earth/2

and g_X = 2g

Therefore,v=\sqrt(2(2g)(R/2))=v_0

Which of the following ocean motions are powered by the wind? waves tides surface currents deep ocean currents
Effectus [21]

At the entrance of most beaches, there is a bulletin board with notices about water conditions: maybe a faded sign warning about rip currents and a list of this week's tide tables. Most people pass them by without a second thought, but if you want to enter the ocean, it is important to know its movements, whether to avoid being caught in a riptide or to figure out when the waves will be at their best.


Hope this helps

A car is moving in uniform circular motion. If the cars speed were to double to keep the car moving with the same radius the acc
Stells [14]

Answer:

<em>The centripetal acceleration would increase by a factor of 4</em>

<em>Correct choice: B.</em>

Explanation:

<u>Circular Motion</u>

The circular motion is described when an object rotates about a fixed point called center. The distance from the object to the center is the radius. There are other magnitudes in the circular motion like the angular speed, tangent speed, and centripetal acceleration. The formulas are:

v_t=w\ r

\displaystyle a_c=\frac{v_t^2}{r}

If the speed is doubled and the radius is the same, then

\displaystyle a_c=\frac{(2v_t)^2}{r}

\displaystyle a_c=4\frac{v_t^2}{r}

The centripetal acceleration would increase by a factor of 4

Correct choice: B.
