Is proportional to the value of the normal force acting on the object.
Answer:
3.4 x 10^-4 T
Explanation:
A = 1.5 x 10^-3 m^2
N = 50
R = 180 ohm
q = 9.3 x 106-5 c
Let B be the magnetic field.
Initially the normal of coil is parallel to the magnetic field so the magnetic flux is maximum and then it is rotated by 90 degree, it means the normal of the coil makes an angle 90 degree with the magnetic field so the flux is zero .
Let e be the induced emf and i be the induced current
e = rate of change of magnetic flux
e = dФ / dt
i / R = B x A / t
i x t / ( A x R) = B
B = q / ( A x R)
B = (9.3 x 10^-5) / (1.5 x 10^-3 x 180) = 3.4 x 10^-4 T
Answer:
a) 
b)
c)
d)= 0 and the direction of motion is equal to zero
Explanation:
a) compton shift
b) the new wavelength
![=hc[\frac{1}{\lambda'}-\frac{1}{\lambda}]](https://tex.z-dn.net/?f=%3Dhc%5B%5Cfrac%7B1%7D%7B%5Clambda%27%7D-%5Cfrac%7B1%7D%7B%5Clambda%7D%5D)
![\Delta E = 6.626*10^{-34}*(3*10^8)[\frac{1}{14.84*10^{-12}}-\frac{1}{4.8*10^{-12}}]](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%206.626%2A10%5E%7B-34%7D%2A%283%2A10%5E8%29%5B%5Cfrac%7B1%7D%7B14.84%2A10%5E%7B-12%7D%7D-%5Cfrac%7B1%7D%7B4.8%2A10%5E%7B-12%7D%7D%5D)
C)By conservation of energy, the kinetic energy of recoiling electron is equal to the magnitude of energy between the photon energy
d) the angle between the positive direction of motion
= 0
the direction of motion is equal to zero.

Answer:
%Open the file.
fID = fopen('parts_inv.dat');
%Read from the file.
data = fscanf(fID,'%d\t%f\t%d',[3,inf]);
%Close
fclose(fID);
%Restore the data.
data = data';
%Get the size
[rs, cs] = size(data);
%Set value.
invCost = 0;
%Loop
for rw = 1 : rs
%Find cost
invCost = invCost + (data(rw, 2) * data(rw, 3));
%Loop end
end
%Display the cost.
fprintf('Total cost: %4.2f\n\n', invCost);
