Susan is correct. honey is made of many substances.
Answer:
Explanation:
Given that,
Current in wire is
I = 10A
And the current makes an angle of 30° with respect to the magnetic field
Then, θ = 30°
And the magnetic field is
B = 0.3 T
Length of the wire is
L = 0.5m
Force on the wire F?
The force on the wire in calculated using
F = iL × B
Where
The magnitude of the cross produce of L and B is
L × B = LB•Sinθ
Then, force becomes
F = iLB•Sinθ
F = 10 × 0.5 × 0.3 × Sin30
F = 0.75 N
The force on the wire is 0.75 Newton
A ) <em>Speed</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>scalar quantity and velocity is a vector quantity.</em>
Explanation:
The given data is as follows.
F =
q =
v = 385 m/s
= 0.876
Now, we will calculate the magnitude of magnetic field as follows.
B =
=
= T
= 10.65 T
Thus, we can conclude that magnitude of the magnetic field is 10.65 T.
