Answer:
The mass is
Explanation:
From the question we are told that
The speed of the charge is
The magnetic field is
The radius is
The value of the charge is
The centripetal acting on the charge moving in the circular orbit is mathematically represented as
Now this centripetal force is due to the force exerted on the charge by the magnetic field on the charge which is mathematically represented as
At the maximum of this magnetic force
So
Now given that it is this magnetic force that is causing the circular motion we have that
=>
=>
substituting values
Answer:
K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹
Explanation:
Rate of flow of heat through a material is given by the following expression
where Q is amount of heat flowing in time t through area A and a medium of thickness d having two faces at temperature difference δT . K is thermal conductivity of the medium .
Here Q = 3.34 x 10⁶/6 , t = 24 x 60 x 60 = 86400 s , A = .332 X .332 = .0110224 m² , δT = 104.7
Put these values here
K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹
