Answer
given,
force per unit length = 350 µN/m
current, I = 22.5 A
y = y = 0.420 m
I₂ = 32.67 A
distance where the magnetic field is zero
there the distance at which the magnetic field is zero in the two wire is at 0.248 m.
For fundamental frequency of a string to occur, the length of the string has to be half the wavelength. That is,
1/2y = L, where L = length of the string, y = wavelength.
Therefore,
y = 2L = 2*0.75 =1.5 m
Additionally,
y = v/f Where v = wave speed, and f = ferquncy
Then,
v = y*f = 1.5*220 = 330 m/s
I think the answer is c) 1
Hope it helps and have a good day
Answer:
Yes energy does take up space.
Explanation:
Every form of energy has a defining characteristic; sound is the vibration of molecules, electricity is the movement of electrons, and mass is the thing that take up space.
Answer:
B. Objects do not have to touch each other to experience a force.
Explanation:
For example ..One of the noncontact forces is magnetic force whereby a magnetic object will be attracted to another magnetic object of oppsite charged particles, through waves called electromagnetic waves. On the other hand, the two magnetic objects of similar charged particles can repel through electromagnetic waves..
