Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.

Nookie1986 [14]

Answer:

The kinetic energy is 200.000 Joule (200KJoule)

Explanation:

We use the formula of kinetic energy:

Ec =1/2 x m x v^2

Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule

200.000J/1000KJ/J=200 kJoule

A wire of a given material has an electric field of 0.100 mV/m when a potential is applied. The wire has 8.49 x 1028 conduction

Bond [772]

The uniform current density in the wire is 5.43 x 10²⁷ A/m².

<h3>Current density in the wire</h3>

The uniform current density in the wire is calculated as follows;

J = total current / total area

The given parameters:

Conduction of the wire = 8.49 x 10²⁸ e/m²
time, t = 2.5 x 10⁻¹⁴ s

$J = \frac{I}{A} = \frac{Q}{At} \\\\J = \frac{8.49 \times 10^{28}e/m^3 \ \times \ 1.6 \times 10^{-19} \ C/e}{2.5 \times 10^{-14} \ s \ \times ( 0.1 \times 10^{-3} \ V/m)} \\\\J = 5.43 \times 10^{27} \ A/m^2$
