A. Since it does not say the ball is moving your answer is A.
Velocity of proton= 4782 m/s
Explanation:
For proton, the centripetal force required for circular motion is provided by the magnetic force,
so Fm= Fc
q v B = m v²/r
m= mass of proton
v= velocity
B =magnetic field=0.05 T
q= charge= 1.6 x 10⁻¹⁹
r= radius = 1 mm =0.001 m
v= q B r/m
V= (1.6 x 10⁻¹⁹)(0.05)(0.001)/(1.673 x 10⁻²⁷)
V= 4782 m/s
M = molar mass of the helium gas = 4.0 g/mol
m = mass of the gas given = 18.0 g
n = number of moles of the gas
number of moles of the gas is given as
n = m/M
n = 18.0/4.0
n = 4.5 moles
P = pressure = 2.00 atm = 2.00 x 101325 Pa = 202650 Pa
V = Volume of balloon = ?
T = temperature = 297 K
R = universal gas constant = 8.314
Using the ideal gas equation
P V = n R T
(202650) V = (4.5) (8.314) (297)
V = 0.055 m³
Answer:
This is the answer of your question.
V = (1 / p) × p0×V0 = (1 / 219kPa) × 117kPa × 3L = 1.06L
