The Thermal energy from the fire moves to the water in the forms of heat.

Thermal energy is the energy that comes from heat which generated by the movements of tiny particles of an obejct. The faster the particles move, the more heat energy it will generates

Hope this help you out

Which of the following is a device that converts electrical energy into mechanical energy? A. Generator B. Transformer C. Magnet
kaheart [24]
A generator transforms mechanical into electrical, a transformer reduces/increases the voltage of an alternating current, a magnet attracts metal, and a motor converts electrical energy into mechanical energy.
So, the answer is Motor.

melisa1 [442]

Answer:

2.38732 rpm

1.22625 rad/s²

163.292°

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration = \frac{1}{8}g

d = Diameter of wheel = 2 m

r = Radius of wheel = \frac{d}{2}=\frac{2}{2}=1\ m

v = Speed of elevator = 25 cm/s

Angular speed is given by

\omega=\frac{v}{r}\\\Rightarrow \omega=\frac{0.25}{1}\\\Rightarrow \omega=0.25\ rad/s=0.25\times \frac{60}{2\pi}\\\Rightarrow \omega=2.38732\ rpm

The angular speed of the wheel is 2.38732 rpm

Angular acceleration is given by

\alpha=\frac{a}{r}\\\Rightarrow \alpha=\frac{\frac{1}{8}g}{r}\\\Rightarrow \alpha=\frac{\frac{1}{8}\times 9.81}{1}\\\Rightarrow \alpha=1.22625\ rad/s^2

The angular acceleration of the wheel is 1.22625 rad/s²

Angular displacement is given by

\theta=\frac{s}{r}\\\Rightarrow \theta=\frac{2.85}{1}\\\Rightarrow \theta=2.85\ rad=2.85\times \frac{360}{2\pi}\\ =163.292\ ^{\circ}

The angle the disk turned when it has raised the elevator is 163.292°
