Answer:
12 cm
Explanation:
We shall use Lens makers formula here which is as follows

Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )

= .5 x ( 15 + 10 ) / 15 x 10
= 
F = 12 cm
Answer:
59.4 N
Explanation:
The force exerted on a current-carrying wire due to a magnetic field perpendicular to the wire is given by

where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
Here in this problem, we model the strike as a current-carrying wire, so we have:
I = 49,500 A is the current
L = 1 m is the length (we want to find the force per each meter of length)
is the strength of the magnetic field
Therefore, the force on each meter of the current due to the magnetic field is:

Answer:
Explanation:
The east vector is 10cos45 = 7.07 km
The north vector is 10sin45 - 10 = -2.93 km
The displacement magnitude is
d = √(7.07² + 2.93²) = 7.65... = 8 km
θ = arctan(-2.93/7.07) = -22.51... = 23° south of east.
