A coil of Nichrome wire is 25.0 m long. The wire has a diameter of 0.400mm and is at 20.0°C. If it carries a current of 0.500 A,
yaroslaw [1]

The power delivered to the coil is 0.5 Watts

<h3>Resistivity of a material</h3>

The formula for calculating the power delivered to it is expressed according to the equation

Power = I²R

where

I is the current

R is the resistance

Given

Current = 0.500A

Determine the resistance using the resistivity formula

R = ρL/A

Substitute the given parameters

R = 10^-6*(25)/0.002²

R = 2ohms

Substitute

Power = I²R

Power = (0.5)²(2)

Power = 0.5watts

Hence the power delivered to the coil is 0.5 Watts

you measured the torque caused by the gyroscope's weight by lifting up the end of the gyroscope (at 7.5 inches). If you measured
DIA [1.3K]

Answer:

i) No, the spring scale does not read a different value

ii) The torque will read a different value, it will reduce

iii) The spring scale does not need to be measured at the center of mass location.

Explanation:

The torque caused by the gyroscope can be given by the relation,

\tau = r × f

\tau = rf cos \theta

The torque measured by the gyroscope varies directly with the distance, r.

A decrease in the distance r will also cause a decrease in the value of the torque measured. When the distance, r is reduced from 7.5 inches to 5 inches, the torque caused by the gyroscope's weight also reduces.

The weight of the gyroscope remains constant despite the reduction in the distance because the weight  of the gyroscope is not a function of the distance from the gyroscope. Therefore, the spring scale will not read a different value.

Yes, the spring scale does not need to be measured from the center of mass location because the weight does not depend on the location of measurement. The reading of the sprig scale remains constant.
