Answer:
OD. The wave diffracted as it passed through the opening in the barrier.
Explanation:
A progressive wave (i.e waves in motion) has the capacity to bend around an obstacle on its path. This is one of the general properties of waves called diffraction. Others are: reflection, refraction, interference. Note that only transverse waves undergo polarization.
Diffraction of waves is the ability of waves to bend around an obstacle on its path during progression.
Thus, the bending of the part of waves as it passes through the barrier implies that the wave diffracted as it passed through the opening in the barrier.
I think it's D)!!!!!!!!!!
Answer:843.75kg
Explanation:
kinetic energy(ke)=432000j
Velocity(v)=32m/s
Mass(m)=?
Ke=(mxv^2)/2
432000=(mx32^2)/2
432000=(mx32x32)/2
Cross multiplying we get
432000x2=(mx1024)
864000=1024m
Divide both sides by 1024
864000/1024=1024m/1024
843.75=m
m=843.75kg
Given Information:
Current = Ii = 7.2 A
Number of turns inner coil = Ni = 140
Number of turns outer coil = No = 180
Radius inner coil = ri = 0.015 m
Radius outer coil = ro = 0.023 m
Required Information:
outer coil current = Io = ?
Answer:
Io = 8.6 A
Step-by-step explanation:
We have two coils, subscript i denotes inner coil and o denotes the outer coil.
According to the Biot-Savart Law
B = μ₀IN/2r
we will equate the inner and outer magnetic fields
Bi=Bo
μ₀IiNi/2ri = μ₀IoNo/2ro
μ₀ and 2 cancels out
Io = Ii*Ni*ro/No*ri
Io = 7.2*140*0.023/180*0.015
Io = 8.6 A
Therefore, a current of 8.6 A is needed to flow in opposite direction so that the magnetic field is opposite and the net magnetic field will be zero.
Answer:
Motion is just movement needing a force to act upon it. Pushing and pulling are examples of forces that can sped things up or slow things down. There are two types of forces, at a distance force and contact forces.
