Which substance—wood or steel—is the better conductor? A conductor is a material that requires very littleheat energy to experience a change in temperature. Explain your answer.
Answers
Answer 1
Answer:
The better substance is steel because lightning hits iron more than wood
Answer 2
Answer:
Steel because good conductors are made of metal and steel is metal.
A conductor allows electrons to move freely from particle to particle whereas an insulator does not. This is mainly metals as metallic bonding creates a sea of delocalised electrons that can flow freely. Molten ionic substances also conduct electricity as they have free e- that can move.
just to clarify, there are different kinds of conductors, mainly heat and electricity. A conductor is something that is able to allow heat/elect to flow through it easily whereas insulator, basically means the opposite

What is difference between kilowatt and kilowatt hour?
Answers
Those two units can be compared to a 'mile per hour' and a 'mile per hour - hour'. One is a rate. The other is a quantity, after maintaining a rate for some time.
-- 'Joule' is a unit of energy. It's the amount of work (energy) you do when you push with a force of 1 newton though a distance of 1 meter. Lifting 10 pound of beans 3 feet off the floor takes about 40.7 joules of energy.
-- 'Watt' is a rate of using energy . . . 1 joule per second. If you lift 10 pounds 3 feet off the floor in 1 second, your power is 40.7 watts.
-- 'Watt-second' is the amount of energy used in one second, at the rate of 1 joule per second . . . 1 joule.
-- 'Watt-hour' is the amount of energy used in one hour, at the rate of 1 joule per second . . . 3,600 joules.
-- 'Kilowatt' is a bigger rate of using energy . . . 1,000 joules per second.
-- 'Kilowatt - second' is the amount of energy used in one second, at the rate of 1,000 joules per second . . . 1,000 joules .
-- 'Kilowatt - hour' is the amount of energy used in one hour, at the rate of 1,000 joules per second . . . 3,600,000 joules .
Depending on where you live, 3,600,000 joules of energy bought from the electric company costs something between 5¢ and 25¢.
Kilowatt hour is a measure of ENERGY Kilowatt is a measure of POWER
If Inability to maintain posture while standing still would indicate a problem with which equilibrium receptor?
Answers
The inability to maintain posture while standing still would indicate a problem with the static equilibrium receptors. Static equilibrium receptors provide information about body position relative to the force of gravity: standing upright v. being upside done. Hope this helps.
Cell phone signals passing through walls is an example of A.) Reflection or scatteringB.) Absorption C.) Transmission D.) Emission
Answers
B.) Absorption Cause it us measured by how much the wall absorbs and doesn’t let pass through.
Solar cells convert what type of energy into electrical energy?
Answers
In what must certainly rank as one of the most startling coincidences in all of science and technology, the cells referred to as "solar" perform their function by deriving electrical energy from the energy in "solar" radiation.
