Answer:
Magnetic field, B = 0.199 T
Explanation:
It is given that,
Radius of circular loop, r = 11.7 cm = 0.117 m
Magnetic flux through the loop,
The magnetic flux linked through the loop is :
Here,
or
B = 0.199 T
So, the strength of the magnetic field is 0.199 T. Hence, this is the required solution.
Answer:
Explanation: The planet average distance = 42300km
Kepler's 3rd Law also known as the Harmonic Law states that;
for each planet orbitting the sun, its side real period squared divided by the cube of the semi-major axis of the orbit is a constant.
A planet, mass m, orbits the sun, mass M, in a circle of radius r and a period t. The net force on the planet is a centripetal force, and is caused the force of gravity between the sun and the planet.

Answer:
The distance between the object is
Explanation:
The free body diagram of this setup is on the first uploaded image
From the question
The diameter of closely packed cones in the fovea of the eye is =
The distance of separation by one cone(not excited ) is
The distance between the two point-like object is l
The diameter of the eye is D = 2 cm
The distance of the two point-like object from the near point of the eye is A = 28 cm
From the diagram we see that the light from the two point-like object form a triangle of similar base l and d and height D and A
So for a triangle with similar base we have that
making l the subject we have
