Answer:
an element with a small number of valence electrons and a large atomic radius
An electric generator works on the principle of Faraday's law of electromagnetic induction. Faraday's law of electromagnetic induction states that “whenever a current carrying conductor are placed in the magnetic field, then a flux is induces in the circuit due to which a current start to flow in the rotor also.

Answer:
-1.19 m
Explanation:
R1 = + 4 cm
R2 = - 15 cm
n = 1.5
distance of object, u = - 1 m
let the focal length of the lens is f and the distance of image is v.
use lens makers formula to find the focal length of the lens
By substituting the values, we get
.... (1)
By using the lens equation
from equation (1)
v = -1.19 m
