I believe it's Gamma Rays. Hope my answer helped :)
F=ma
=> 20=10m so m=2
Then the force is doubled 20.2=40
F'=ma'
m does not change so 40=2.a'
a'=20 which is option b.
Give a brainliest please:-)

Answer:
option C
Explanation:
given,
Period of oxygen molecule = 6 s
number of molecule = 6 x 10²³
Area of wall = 2 cm²
speed of molecule = 400 m/s
mass of O₂ molecule = 5.344 × 10⁻²⁶ Kg
we know,
Δp= F Δt
Δp change in momentum
Δp = N.m.Δv
where N is the number of oxygen molecules strike a wall
Δv = v - (-v)= 2 v
Pressure,
P = 21376 Pa
P = 21.4 kpa
hence the correct answer is option C
