Answer:
D. 6.25 J
Explanation:
∴ k = 50 N/m
∴ Δx = 0.5 m
⇒ EPE = 1/2*50 N/m*(0.5m)²
⇒ EPE = 6.25 N.m = 6.25 J
The correct answer is all of the above.
Nuclear or radioactive radiation or radioactive decay refers to the procedure by which an unstable atomic nucleus loses energy in the form of mass in its rest frame by discharging radiation like a beta particle, alpha particle, or a gamma ray. A substance comprising such unstable nuclei is regarded as radioactive. The process does not need any input of energy.
Sorry I didn’t get the answer
Answer:
V = 5.17L
Explanation:
Mass of gas = 8.7g
T = 23°C = (23 + 273.15)K = 296.15K
P = 1.15 atm
V = ?
R = 0.082atm.L / mol.K
From ideal gas equation
PV = nRT
P = pressure of the gas
V = volume of the gas
n = no. Of moles
R = ideal gas constant
T = temperature of the gas
no of moles = mass / molar mass
Molar mass of Chlorine = 35.5g / mol
No. Of moles = 8.7 / 35.5
No. Of moles = 0.245 moles
PV = nRT
V = nRT / P
V = (0.245 * 0.082 * 296.15) / 1.15
V = 5.9496 / 1.15
V = 5.17L
The volume of the gas is 5.17L
