Some of the energy is converted into heat. This is the main reason why electrical material gets hot when connected to a source. Therefore, your initial energy does not equal final energy. This does not violated energy conservation law because the energy is being converted so it is never lost.
Answer:
When an object vibrates, it causes the molecules in the air around it to move. These molecules collide with nearby molecules, forcing them to vibrate as well. As a result, they collide with more surrounding air molecules.
Explanation:
Answer:
x=0.154kg
Explanation:
(x*L)+(0.5kg*4200*50)+(x*4200*(-50)=0
(x*333 000J/kg*c)+(0.5kg*4200J/kg*C*(-40C))+(x*4200J/kg*C*50C)=0
Given: Height h = 6 ft or the vertical component "y" this become the initial height, therefore if you want to know the total height of the stone with respect to the ground. you can just add up the two value below.
Initial Velocity Vi = 41 ft/s g = -32.2 ft/s² acting downward
Require: Height h = ?
Formula: y = Vf² - Vi²/2g
y = 0 - (41 ft/s)²/2(-32.2 ft/s²)
y = -1,681 ft²/s²/(-64.4 ft/s²)
y = 26.10 ft
