Answer:
The magnitude of the Force is 
and the direction is South
Explanation:
From the question we are told that
The magnetic field point due west and since East point toward the positive x -axis
then this magnetic field would be mathematically represented as
Now from the question we are told that the kinetic energy is
Now this kinetic energy can be mathematically represented as
Where m is the mass of proton which has a general value of
Now making the subject of the formula
Substituting values we have
Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive
So the velocity would be
Now the magnetic Force can be mathematically represented as
Where q is the charge on the proton which has a general value of 
Now substituting the value
Now according to Fleming's left hand rule the direction of the magnetic force is south toward the negative Y - direction 
So the force can be denoted as

Answer: Heat current through the insulator=196W
Electric power= 196W
Explanation: Given: Kglass = 0.040W/m
Temperature of inside glassTi=175°C
Temperature of outside glass To= 35°C
Area=1.4m^2 , L= 4×10^-2
Heat current(H)= K ×A× (Ti - To)/L
Substituting the values into the equation
H = 0.04 × K × 1.4 ×(175-35)/4×10^-2
H= 196W.
The electric power = Heat current =196W
The electric power is the magnitude of heat current
Answer:
Two off-centered spots in the first phase of the experiment; one centered spot in the second phase of the experiment.
Explanation:
If two particles are selected in which both have the same electron mass and the same velocity, but one of the particles has a charge and the other particle has a charge of 2e. During the first stage of the experiment, the two particles have an electric force equal to F = Eq in the entire vertical direction. The acceleration of particle is equal to a = (Eq)/m.
In the second part of the experiment, the magnetic field cancels the electric field. In this way, the electric force and the magnetic force cancel each other out. Therefore, the net force acting on each particle is equal to zero.
Because these two forces cancel each other out, the particles fail to create two off-center points on the screen in the second part of the experiment. Also, if the loads are different, the deviation is also different. In this way, an off-center point cannot be achieved in the first part of the experiment. There will be two off-center points.
