An electric slot car has a coil with 100 turns of wire. These loops have a current of 0.1 A and cover an area of 0.1 cm2. If the

Marrrta [24]

Answer:

The torque will be felt by the coil is zero

Explanation:

The torque is:

$\tau =\mu B=\mu Bsin\theta$

Where

μ is the magnetic moment = N * I * A, where N is the number of turns, I is the current and A is the area

A = 0.1 cm² = 1x10⁻⁵m²

$\mu =100*0.1*1x10^{-5} =1x10^{-4} Am^{2}$

If the angle between the area and the magnetic field is 0 (are in parallel), then:

$\tau =1x10^{-4} *1*sin0=0Nm$

Oceanographers use submerged sonar systems, towed by a cable from a ship, to map the ocean floor. In addition to their downward

KATRIN_1 [288]

Answer:

Tension in the cable is T = 16653.32 N

Explanation:

Give data:

Cross section Area A = 1.3 m^2

Drag coefficient CD = 1.2

Velocity V = 4.3 m/s

Angle made by cable with horizontal =30 degree

Density $\rho \ of\ water= 1000 kg/m3$

Drag force FD is given as

$F_{D} = \fracP{1}{2} \rho v^{2} C_{D} A$

$= 0.5\times 1000\times 4.32\times 1.2\times 1.3$

Drag force = 14422.2 N acting opposite to the motion

As cable made angle of 30 degree with horizontal thus horizontal component is take into action to calculate drag force

TCos30 = F_D

$T = \frac{F_D}{cos30}$

$T =\frac{ 14422.2}{cos 30}$

T = 16653.32 N

Under what conditions can heat be given to a body without raising its temperature

Lina20 [59]

Heat can be given to a substance without raising its temperature,When a substance is changing its physical state[for eg from solid to liquid and liquid to gas ]. The heat energy which has to be supplied to change the state of substance is called its Latent Heat. Latent heat does not raise the temperature .
