Answer:
A wire carrying a 30.0-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.16-N force on the 4.00 cm of wire in the field. What is the average field strength?
Explanation:

Answer:
(a) 5.04 eV (B) 248.14 nm (c) 
Explanation:
We have given Wavelength of the light \lambda = 240 nm
According to plank's rule ,energy of light
Maximum KE of emitted electron i= 0.17 eV
Part( A) Using Einstien's equation
, here 
is work function.
= 5.21 eV-0.17 eV = 5.04 eV
Part( B) We have to find cutoff wavelength
Part (C) In this part we have to find the cutoff frequency
Answer:
Only the perpendicular component of gravity is responsible for the rotation because wind points toward the pivot.
