If a ball is tossed straight up into the air, at what position is its potential energy the greatest?A.when it reaches the top of its flight  
B.when it first leaves your hand  
C.when it approaches the top of its flight  
D.when it begins to fall back to your hand.
Please Help

Answers

Answer:

A.when it reaches the top of its flight

Explanation:

The potential energy of an object is given by:

U=mgh

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth at which the object is located above the ground

Therefore, we see that the higher the object, the larger its potential energy: this means that the ball will have the greatest potential energy at the top of its trajectory.
A. when it reaches the top of its flight

potential energy increases as the height of the object does, and the highest point of a ball's flight is when it reaches the top. 

A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.

Light traveling through air strikes the surface of the four different materials shown. Which material reflects light but does not refract it?1. Diamond
2. water being poured
3. triangular glass prism
4. 2 silver spoons

PLZ HELP!!

Answers

The 2 silver spoons are the materials that will reflect light but does not refract it. The correct option among all the options that are given in the question is the last option or option "4". The other materials given in the question reflects as well as refracts light that falls on them. I hope the answer comes to your help. 

I just took the test and the two silver spoons was correct :)

OK THIS WILL WORTH 25 POINTS IF BEST: WHAT IS THE ONLY NATURAL SUBSTANCE FOUND ON EARTH THAT CAN BE 3 STATES OF MATTER?

Answers

Every natural substance CAN exist as solid, liquid, or gas, if you make the temperature and pressure right. The only one that exists in all three states all the time, all around us, in the same range of temperature and pressure found naturally on Earth and in which we live comfortably, is water.
