8. What current flows through a 1.15 kW electric fire at a potential difference of

Vilka [71]

Answer:

I = 5[amp]

Explanation:

Electrical power is defined as the product of voltage by current.

$P=V*I$

where:

P = power = 1150 [W]

V = voltage = 230 [V]

I = current [amp]

Now replacing:

$1150=230*I\\I=1150/230\\I=5[amp]$

A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]

A charge Q is transferred from an initially uncharged plastic ball to an identical ball 17 cm away. The force of attraction is t

Alecsey [184]

Answer:

2.92 x 10¹² electrons

Explanation:

given,

distance between two plastic ball, r = 17 cm

r = 0.17 m

Force of attraction = F = 68 mN

F = 0.068 N

number of electron transferred from one ball to another.

using Coulomb Force equation

$F = \dfrac{kq^2}{r^2}$

$0.068 = \dfrac{9\times 10^9\times q^2}{0.17^2}$

q² = 2.1835 x 10⁻¹³

q = 4.67 x 10⁻⁷ C

now, number of electron

$N = \dfrac{q}{e}$

e is the charge of electron which is equal to 1.6 x 10⁻¹⁹ C

$N = \dfrac{4.67\times 10^{-7}}{1.6\times 10^{-19}}$

N = 2.92 x 10¹² electrons

electrons were transferred from one ball to the other is 2.92 x 10¹²

Ratling [72]

Answer:

Force is the strength or weight of things that depends on movement. The types of forces are conteact force, spring force, applied force, air resistance force, normal force, frictional force, tension force, and non-contact force.
