Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.
Answer:
B = 0.025T.

Answer:
a)1.13×10³
b)1.6×10³
Explanation:
Given:
Boltzmann's constant (K)=1.38×10^-23 J/K
atmoic mass of helium = 4 AMU or 4×1.66×10^-27kg
a)The formula for RMS speed (Vrms) is given as
where
K= Boltzmann's constant
T= temperature
m=mass of the gas
b) RMS speed of helium when the temperature is doubled
Answer:
the mass + the 1 constant g-force = the speed without adding air resistance
Explanation:
osmium it the most tightly packed alloy in the world so for that it will have a faster acceleration
