Answer:
I think so because if it starts at a low temperature for that material, it should melt when you bring it up to that temperature.
Answer:
They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw. simple machines.
Answer:
Change in the frequency (in Hz) = 104.96 Hz
Explanation:
Given:
Speed of sound in air (v) = 343 m/s
Speed of car (v1) 36 m/s
Frequency(f) = 500 Hz
Find:
Change in the frequency (in Hz)
Computation:
Frequency hear by the observer(before)(f1) = [f(v+v1)] / v
Frequency hear by the observer(f1) = [500(343+36)] / 343
Frequency hear by the observer(f1) = 552.48 Hz
Frequency hear by the observer(after)(f2) = [f(v-v1)] / v
Frequency hear by the observer(f2) = [500(343-36)] / 343
Frequency hear by the observer(f2) = 447.52 Hz
Change in the frequency (in Hz) = f1 - f2
Change in the frequency (in Hz) = 552.48 Hz - 447.52 Hz
Change in the frequency (in Hz) = 104.96 Hz
Answer:
1751399.8902 J
Explanation:
m = Mass of water = 74.6 kg
= Latent heat of fusion =
= 19.2°C
= 0°C
We have the equation for cold body
We have the equation
Energy rejected to the room is 26667799.8902 J
Energy supplied to the device is given by
The energy supplied to the device is 1751399.8902 J
D because u r using your energy to do all the things
