(a) emf = 0.507 V
(b) emf = 0.0507 V
(c) emf = 0.00234 V
Explanation:
Given;
number of turns of the coil, N = 40 turns
diameter of the coil, d = 11 cm
radius of the coil, r = 5.5 cm = 0.055 m
magnitude of the magnetic field, B = 0.4 T
The magnitude of the induced emf is calculated as;
(a) when the time, t = 0.3 s
(b) when the time, t = 3.0 s
(c) when the time, t = 65 s
The <span>physical properties of non-metals are as below:
1) Poor conductors - generally non-metals are poor conductors of heat and electricity.
2)Low melting points - all metals have low melting and boiling points, with graphite being an exception.
3) Brittle - all nonmetals are brittle in nature.</span>

Venus has a surrounding that is approximately one hundred instances thicker than Earth's and has surface temperatures that are extraordinarily hot. Venus no longer has life or water oceans as Earth does.
Venus additionally rotates backward in comparison to Earth and the alternative planets. The geology of Earth is dominated by plate tectonics, Venus has "blob tectonics," wherein the growing of hot material from inside performs a dominant position in sculpting its surface. Venus is also one-of-a-kind from Earth in having miles decrease stage of erosion, because no precipitation and surface wind speeds are very low.
Venus is often called "Earth's dual" because they're similar in size and structure, but Venus has severe floor heat and a dense, poisonous environment. If the sun have been as tall as a typical front door, Earth and Venus could never be about the scale of a nickel.
