Potential Energy (Initial one) = m * g * h
P.E. = 60 * 9.8 * 10
P.E. = 5880
Kinetic Energy (Final One) = 1/2 mv²
K.E. = 1/2 * 60 * (10)²
K.E. = 6000/2
K.E. = 3000
Lost Energy = 5880 - 3000 = 2880 J
In short, Your Answer would be 2880 Joules
Hope this helps!
Answer:
The answer is C. thinking about the smallest particles of matter without experimenting.
They literally gave you the answer but okay.
Correct answer should be: B. 490 Meters
1/2 x 9.8 x 10^2
Plug them in a calculator and you get <u>490 meters. </u>
<u>G </u>= Gravity which is 9.8 m/s^2
<u>T</u>= Time
Answer:
Explanation:
As we know that the wheel is rotated at constant angular speed
so here we can say that the angular speed is given as
now the moment of inertia of all passengers is given as
now work done by machine must be equal to kinetic energy of the system
so we will have
Answer:
These regions are known as compressions and rarefactions respectively. The compressions are regions of high air pressure while the rarefactions are regions of low air pressure.
