Answer: Revolution
Explanation:
The Earth rotates about its axis in 23 hours 56 minutes i.e. in one day. The Earth revolves around the Sun in one year (365 and 6 hours). Axis is an imaginary line passing through the center of any body about which it rotates. Solstice is an event when Sun is passing over Tropic of Capricorn or Tropic of cancer.
Hence, the correct option is The earth completes one <u>Revolution</u> when it travels once around the sun.
48J
Explanation:
Given parameters:
Weight of the book = 16N
Height of the shelf = 3m
Unknown:
Work done to raise the book = ?
Solution:
Work done is defined as the product of force and distance. The force here is the weight of the book which signifies that it was carried in the vicinity of gravitational force.
Work done = Force x distance = weight x distance
Weight is a type of force;
Input the parameters;
Work done = 16 x 3 = 48J
The unit of workdone is in Joules

Therefore, the magnitude of magnetic field at a distance 1.10cm from the origin is 27.3mT
<u>Explanation:</u>
Given;
Number of turns, N = 1000
Inner radius, r₁ = 1cm
Outer radius, r₂ = 2cm
Current, I = 1.5A
Magnetic field strength, B = ?
The magnetic field inside a tightly wound toroid is given by B = μ₀ NI / 2πr
where,
a < r < b and a and b are the inner and outer radii of the toroid.
The magnetic field of toroid is

Substituting the values in the formula:


Therefore, the magnitude of magnetic field at a distance 1.10cm from the origin is 27.3mT
