b. deflects. A DC motor's magnet has a magnetic field that <em><u>deflects</u></em> the wire loop's magnetic field, therefore causing the loop to rotate.
When a conductor, through which an electric current passes, is immersed in a magnetic field, it experiences a deflects force according to the Law of Lorentz creating as result that the loop rotate.

Answer:
Explanation:
Both these questions are based on the Universal Law of Gravitation, which is given by :
F = Gm1m2 / r²
2) F = 6.67 x 10⁻¹¹ x 8 x 10³ x 1.5 x 10³ / 1.5 x 1.5
F = 6.67 x 10⁻⁵ x 8 / 1.5
F = 35.57 x 10⁻⁵ N
3) F = 6.67 x 10⁻¹¹ x 7.5 x 10⁵ x 9.2 x 10⁷ / 7.29 x 10⁴
F = 6.67 x 10⁻³ x 7.5 x 9.2 / 7.29
F = 63.13 x 10⁻³ N
It’s applying force to move an object
Answer:
The transmitted intensity through all polarizers = 34.73
Explanation:
Given :
Incident intensity = 
Angle between the transmission axis and polarizer optic axis = 18°
According to the malus law, when unpolarized or polarized light passes through polarizing disk, the intensity of the transmitted light is directly proportional to the square of the cosine of angle between the transmission axis and polarizer optic axis.
∴ 
Where 
transmitted intensity, 
incident intensity, 
angle between the transmission axis and polarizer optic axis.
Here, there are four polarizing disks so that.
from first disk,
∴ 
₁ 
18°
= 
×
= 
Now ₁ behave as an incident light for second polarizer so we only multiply
term
so we write,
∴ ₂ = ×
From third polarizer,
∴ ₃ = 
×
From forth polarizer,
∴ ₄ = 
×
Therefor, the the transmitted intensity through forth polarizer = 34.73 
.
