Asquare 1300-turn coil with the area of 0.2 m2 is situated in the xy-plane in a region where the magnetic field is (50k) μt. what is the average induced emf when this coil is rotated into the xz-plane in 0.2 s?

e = 65 mA

Explanation:

given,

number of turn = 1300

Area = 0.2 m²

B = 50 x 10⁻⁶T

t = 0.2 s

coil rotate in x-z plane

θ = 90°  to θ = 0°

maximum induced emf

e =0.065

e = 65 mA

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the answer is a. at the equator
