Answer:
A. an equal and opposite reaction force
Explanation:
This means that there is a natural reaction of force
- From the general law of gases: PV = nRT,
where P is the pressure (atm),
V is the volume (L),
n is the number of moles,
R is the general gas constant (8.314 L.atm/mol.K),
T is the temperature in Kelvin
- at constant volume of the gas: P1T2 = P2T1
P1 = 3.20 atm, T1 = 300 K, T2 = 290 K, P2 = ??
(3.20 atm)(290 K) = P2(300 K)
P2 = (3.20 atm)(290 K)/ (300 K) = 3.093 atm
Explanation:
the enerfy of of one photon of this light is 4.85x10^-19 J
<h2>E= 6.63 x 10^-34 J/S x 7.32 x10^14 S ^-1</h2>
E= 4.85x10^-19 J
