Conservation law, also called law of conservation, in physics, several principles that state that certain physical properties (i.e., measurable quantities) do not change in the course of time within an isolated physical system
Without a change in pressure
V/T = V/T
Before change = after change - expansion
x = volume at m3
(0.5)/20 = x/45
.025 = x/45
.025 * 45 = x
1 = x
The volume of this gas is 1 m3.
Hope this helps :) also the gas expanded .5 of m3.
if one of the charge is doubled, the electric potential energy would be doubled too
Energy cannot be created nor be destroyed
Answer:
e = 1.21 mV
Explanation:
given,
length of rod = 10 m
height of drop = 4.89 m
Earth’s magnetic field = 12.4 µT
acceleration of gravity = 9.8 m/s²
velocity of the beam
v = 9.79 m/s
emf of the beam
e = B l v
e = 12.4 x 10⁻⁶ x 9.79 x 10
e = 1.21 x 10⁻³ V
e = 1.21 mV
