Kinetic energy formula:
E k = m v²/2
If the velocity is doubled:
E k 1 = m ( 2 v )² / 2 = 4 m v² / 2 = 4 E k
Answer: kinetic energy is quadrupled.
P = MxV
P1 = 500 x 2.5 = 1250
P2 = 3 x ? = 1250
P2 = 1250/3 = 416.66 m/s
Answer:
We will use Potential Energy Formula
Potential Energy = mass × gravitation × height
PE = 0,55 × 10 × 4
PE = 22 J (A)
Dalton's theory was identified using light microscope images of atoms.
Perpetual motion is motion of bodies that continues indefinitely. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an energy source. This kind of machine is impossible, as it would violate the first or second law of thermodynamics.
