Answer:
the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
Explanation:
energy of ultraviolet light =
=
=7.91 × 10⁻¹⁹ J
=4.94 e V
energy released by the electron = 4.94 - 4.70
= 0.24 e V
potential at the surface of sphere =
0.24 =
Q = 0.132 × 10⁻¹¹ C
hence, the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
Answer:
The ability of gases to be forced or squeezed into smaller volumes is called compressibility
Velocity of sound travels faster in solids than in liquids, and faster in liquids than in gases because "the density of solids is higher than that of liquids, meaning that the particles are closer together."
The fertilised ovule<span> goes on to form a seed, which contains a food store and an embryo that </span>will<span> later </span>grow into<span> a new plant</span>
That's electric "current", usually described in 'Amperes'.
1 Ampere = 1 Coulomb per second ... "the rate at which
charge passes a point in the circuit".
