The torque value is 560 Nm, so the result does not depend on the value of Ф.
Given:
Mass=80.0 g
Radius=20.0 cm
Magnetic field=0.35T
In a magnetic field, a loop of current-carrying wire will experience the following torque:
τ=μ×Β
Here, is the μ magnetic moment and Β is the magnetic field.
τ= 1600 × 0.35 T
τ= 560 Nm
<h3>
What is torque and its SI unit?</h3>
The rotating equivalent of force is torque. It is also known as the moment, moment of force, rotating force, or turning effect depending on the field of research. It serves as an example of how a force can alter a body's rotational motion.
The Newton-metre, or kgm2sec-2, is the SI unit for torque. How did we get to this point? Considering the equation Torque = Force X Distance Torque is measured in newton-meters, whereas distance is measured in meters and force is measured in newtons.

Answer:
The two skaters will move with a common speed of 1.19 m/s.
Explanation:
Given that,
Mass of Alex,
Initial velocity of Alex,
Mass of Barbara,
Initial velocity of Barbara,
After the collision, the two skaters move together at a common velocity. Let V is the common velocity. Using the conservation of momentum as :
Magnitude of final velocity:
So, the two skaters will move with a common speed of 1.19 m/s.
Answer:
#2) The spaceship's forward motion must be slowed down so the earth's gravitational pull on it will be stronger than the ship's forward motion.
Answer:
5 orders.
Explanation:
The condition for diffraction maxima,
So maximum m is 5 which means it produce 5 orders.
Therefore, the number of possible order will produce by visible light of wavelength 457 nm is 5 orders.
