A constant torque of 260 Nm acts on a flywheel. If the flywheel makes 25 complete revolutions in 2 minutes, what is the power ex

Answer:

Consequently, the temperature difference across the material will be

Explanation:

In this case, we apply the Fourier Law of heat conduction expressed by the following equation:

  (1)

Where k = thermal conductivity = 0.2 W/ mK

A= 1m^2 denotes the cross-sectional area

Q= 3KW signifies the heat transfer rate

is the temperature difference we need to determine

represents the thickness of the material

Initially, we convert 3KW to W, resulting in:

With all variables accounted for, we can substitute and calculate:

Thus, the temperature difference across the material will be

Explanation:

Here’s a revised version of the requirements;

Fill in the blanks with the appropriate terms. Picture a force gauge fixed between the rope and the saddle of the chain carousel. If you keep your feet off the ground while the vehicle is not in motion, the dynamometer shows A / B. When the carousel is spinning, you’ll see C / D displayed on the dynamometer.

A. Your weight including the saddle

C. Value of the rope's strength

B. Your weight

D. Value of the centripetal force

The frequency of a sound remains constant as it departs from the source. It does not alter.

The voices of swimmers do not modify in frequency when transitioning to or from the water. Only their speed and wavelength vary.
