<h3>Heat</h3>
The type of energy that moves between two materials with varying temperatures is referred to by scientists as heat. Because the average translational kinetic energy per molecule in the two materials varies, an energy transfer takes place. Up until thermal equilibrium is attained, heat is transferred from the substance with the higher temperature to the material with the lower temperature. The joule, with 1 joule equalling 1 newton meter, is the SI unit of heat. Imagine the following situation to better comprehend what happens when this energy transfer takes place: Tiny rubber balls are bouncing all over two distinct containers that are full with them. The difference between the average ball speed in one container and the second container is substantial.
(a) Circular metal wires in electrical circuits may have different cross-sectional areas (different diameters) and different lengths. For a given applied voltage, how would the joule heat vary with these parameters

The correct answer is:
D. Extrusive rocks.
The explanation:
when extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.
Answer:
100
Explanation:
= Resistivity of axon
r = Radius of axon
t = Thickness of the membrane
= Resistivity of the axoplasm
Speed of pulse is given by
So, radius is given by
If radius is increased by a factor of 10 new radius will be
So, The radius will increase by a factor of 100.
Vietually every electronic device in widespread use contains some form of capacitors .used to store electricity capacitor aften help computer avoid losing their memory when the batteries an being recharged other device such as amplifiers for car steroeos contain capacitor that store energy until it is nedded by the amplifier motiondetector use capacitor to help achieve the proper timing of the until circuit.
