Answer:
Gay Lussac law
Explanation:
Gay Lussac law states that for a gas kept at constant volume (so, in a rigid container), the pressure of the gas is directly proportional to the absolute temperature.
In mathematical formula:
where
p is the gas pressure
T is the absolute temperature
According to this law, we see therefore that if the absolute temperature of the gas is doubled:
T' = 2T
The pressure will also double:
Answer:
An airplane flying
Explanation:
Both a bird and airplane fly, but the airplane is using more mechanical energy to run and power the plane, causing it to fly.
Answer:
E = 7.99 *10^{-13} J
Explanation:
the given reaction is
we know that energy is given as
where
m_1 H^1 is mass of proton = 1.672622 *10^{-27}
m_1 H^2 is mass of deuterium = 3.344494 *10^{-27}
m_2 H^3 is mass of He = 5.008234 *10^{-27}
E = [1.672622 *10^{-27} + 3.344494 *10^{-27} - 5.008234 *10^{-27} ] *(3*10^8)^2
E = 7.99 *10^{-13} J
Answer:
One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air.
Answer:
An atom always has the same number of electrons as protons. Electrons have an electric charge of -1 and protons have an electric charge of +1. Therefore, the charges of an atom's electrons and protons “cancel out.” This explains why atoms are neutral in electric charge.
