Answer:
Maximum torque on the wire is 
Explanation:
It is given that,
Diameter of the wire, d = 11.1 cm = 0.111 m
Radius of wire, r = 0.0555 m
Magnetic field, 
Current, I = 5 A
We need to find the maximum torque on the wire. Torque is given by :
Torque is maximum when, 
or
So, the maximum toque on the wire is . Hence, this is the required solution.
Gravity i think would be the answer
Answer:
450 × 10 ⁻⁹ N
Explanation:
From the given:
The direction of force is;
Hence, the angle is 45° counterclockwise from + x-axis
However;
the magnitude of the force is:
I believe it's B. A vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork.
Answer:
Angle of refraction
Explanation:
The incident ray is the ray before it reaches the surface.
The refracted ray is the ray after it reaches the surface.
n₁ is called the index of incidence.
n₂ is called the index of refraction.
θ₁ is called the angle of incidence.
θ₂ is called the angle of refraction.
They are related by Snell's law:
n₁ sin θ₁ = n₂ sin θ₂
