2) What must be connected for an electrical current to flow in a simple current?
hjlf

2) What must be connected for an electrical current to flow in a simple current?

<em>d.moving magnets,conductors, load to do work </em>

here moving magnets will work as generator and conductors is used as connectors.

5)What is the purpose of a load in a circuit?

<em>c.provide resistance to keep the voltage strong </em>

Load will provide the resistance to the circuit and help to build the voltage across it

6) What cause an electric current from a generator

<em>d.Magnets and conducting wires move near each other </em>

here when magnets move near wires then it will induce the electric current and behaves like generators

7) What do all generators have in common

<em>b.they transform mechanical into electrical energy </em>

They have magnets and rotating coils which will convert magnetic energy to electrical energy

8) How can we measure electrical current

<em>b.the pressure force is voltage;the # of electrons moving is amperes </em>

this voltage and number of electrons will help to calculate current

Through which one of the following mediums is the velocity of a sound wave the greatest?
Colt1911 [192]

Answer: <u><em>C. Steel</em></u>

Explanation: <em><u>When a sound wave travels through a solid body consisting</u></em>

<em><u /></em>

<em><u>of an elastic material, the velocity of the wave is relatively</u></em>

<em><u /></em>

<em><u>high. For instance, the velocity of a sound wave traveling</u></em>

<em><u /></em>

<em><u>through steel (which is almost perfectly elastic) is about</u></em>

<em><u /></em>

<em><u>5,060 meters per second. On the other hand, the velocity</u></em>

<em><u /></em>

<em><u>of a sound wave traveling through an inelastic solid is</u></em>

<em><u /></em>

<em><u>relatively low. So, for example, the velocity of a sound wave</u></em>

<em><u /></em>

<em><u>traveling through lead (which is inelastic) is approximately</u></em>

<em><u /></em>

<em><u>1,402 meters per second.</u></em>

<em><u /></em>

<u><em /></u>
