The answer to your question is SMOOTH
Answer:
3.8379 meters
Explanation:
A charged particle into an uniform magnetic field describes a circular movement with radius "r" acording to the equation r=(m*v)/(q*B), where m is the mass of the particle, v its velocity, q the charge, and B the perpendicularly uniform magnetic field. Replacing your value on this equation, the radius is 3.8379 m. I suggest to verify the value of the magnetic field, because 9.4 is a extremely high magentic field.
Answer:
E = 73.5 J
Explanation:
Given that,
Mass of a marble, m = 5 kg
It is placed at the edge of a 1.5 m table
We need of find the gravitational potential energy of the marble. It is given by the formula as follows :
E = mgh
E = 5 kg × 9.8 m/s² × 1.5 m
E = 73.5 J
So, the potential energy of the marble is 73.5 J.
Explanation:
a) 120m
b) since Q is the first order constructive interference, the distance between mid point of antennas and Q is 0.5 wavelengths (appear in A-Level question). so the wavelength should be (2)(30) =60m
60m
