Answer:
Ke=electron kinetic energy=
Explanation:
The electron has a mass of 
The speed of light in a vacuum is a universal constant with the value 299 792 458 m / s (186 282,397 miles / s), although it is usually close to 
Kinetic energy (K) is the energy associated with bodies that are in motion, depends on the mass and speed of the body and is calculated using the formula:
Equation(1)
K=kinetic energy (J)
m =mass of the body (kg)
v= speed of the body
for this problem We replace in the equation (1)
= electron mass
=Half the speed of light
=electron speed
We replace in the equation (1) :
The energy kinetic of the electron is 
Answer: The net displacement is 6.40meters
Explanation:
Answer:
α = 1.32 rad/s²
Explanation:
given,
diameter of the bicycle = 0.8 m
radius of the bicycle = 0.4 m
initial speed of the bicyclist,u = 0 m/s
final speed of the bicyclist,v = 22 Km/h = 22 x 0.278
= 6.12 m/s
time,t = 11.6 s
acceleration =
=
=0.53 m/s²
we know,
a = α r
α = 1.32 rad/s²
the angular acceleration of the wheels is equal to α = 1.32 rad/s²
At high pressures, the two factors that cause deviation during ideal gas law calculation are the size of molecular and intermolecular force.
The high pressure causes the molecules to approach each other at a very close distance. In that case, if the intermolecular force of attraction is high, the molecules may undergo a state transition, which will result in a completely different outcome as predicted by Ideal gas law.
If the size of the molecule is more, that is for heavy gases like refrigerants, the ideal gas law deviates due to the fact that, with increase in pressure, the volume of gas can no longer be considered as negligible.
