Answer:
Inhibit the flow of electrons
Explanation:
An electric current usually consists of electrons moving through a wire.
An insulator prevents the flow of an electric current, so it inhibits the flow of electrons.
Explanation:
the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Answer:
r = 4.24x10⁴ km.
Explanation:
To find the radius of such an orbit we need to use Kepler's third law:
![\frac{T_{1}^{2}}{T_{2}^{2}} = \frac{r_{1}^{3}}{r_{2}^{3}}](https://tex.z-dn.net/?f=%20%5Cfrac%7BT_%7B1%7D%5E%7B2%7D%7D%7BT_%7B2%7D%5E%7B2%7D%7D%20%3D%20%5Cfrac%7Br_%7B1%7D%5E%7B3%7D%7D%7Br_%7B2%7D%5E%7B3%7D%7D%20)
<em>where T₁: is the orbital period of the geosynchronous Earth satellite = 1 d, T₂: is the orbital period of the moon = 0.07481 y, r₁: is the radius of such an orbit and r₂: is the orbital radius of the moon = 3.84x10⁵ km. </em>
From equation (1), r₁ is:
Therefore, the radius of such an orbit is 4.24x10⁴ km.

Explanation:
Given that:
Mass of metal = 12g = 0.012
Density of metal = 4 g/cm³ = 4000kg/m³
Density of oil = 1.5g/cm³ = 1500 kg/m³
Recall : density = mass / volume
Volume of metal, V = mass / density = 0.012/ 4000 = 0.000003
0.000003
T + Density of oil * g * V - (0.012 * 9.8) = 0
T + 1500 * 9.8 * 0.000003 - 0.1176 = 0
T = 0.0441 - 0.1176 = 0
T = 0.1176 - 0.0441
T = 0.0735N
Tension, T
