Steel has a melting point of 1510 degrees Celsius. If all items would be placed into a big enough oven and the temperature increased to 1510 degrees, which item would melt first?

All would start melting at the same time because they are made up of the same substance

The battle ship because it has the most area

The silverware because its flat and it melts faster

Making toast involves many energy transformations. As the electricity is forced through the wires, the wires begin to heat up and glow very hot. It is these hot loops of wire that cause the bread to brown making your toast. Describe the energy transformations

Electrical energy-> Thermal energy-> Chemical energy

Chemical energy-> Electrical energy-> Mechanical energy

Thermal energy-> Mechanical energy-> Chemical energy

Electrical energy-> Chemical energy-> Mechanical energy

The girl pedals the bike, which eventually produces steam that rises. What kind of energy transformation is taking place.

Chemical->Mechanical-> Electrical-> Thermal-> Mechanical.

Mechanical-> Electrical-> Thermal-> Mechanical

Chemical-> Electrical-> Thermal-> Mechanical

What is Mechanical energy?

Energy that is possessed by an object due to its motion or position

Energy that changes its physical appearance

Energy that changes chemically like its odor or state of matter

What kind of energy transformation is represented in the system above?

Mechanical-> Electrical-> Light

Light->Chemical-> Electrical-> Sound

It is a cold day. Tom decides to turn on the heat in his home. His home is connected to power lines that eventually receive their power from a hydroelectric dam about 50 miles away. What energy transformations allows tom to heat up his home?

Mechanical energy from the river to electrical energy in the dam. This electrical energy flows to Tom’s home and allows him to turn on the heater, which transforms electrical energy to heat energy

Mechanical energy from the river turns into electrical energy in the dam. This electrical energy flows to Tom’s home which in return makes him turn on the ac which releases chemical energy.

Mechanical energy from the river to Chemical energy in the dam. This chemical energy flows to Tom’s home which in return makes him turn on his heater, which releases heat energy to warm up his home

During a thunderstorm, you see the lighting before you hear the thunder. Which of the following explains this observation?

Light travels faster than sound

Light has a greater mass than sound

Sound has a longer wavelength than light

Sound and light travel at the same speed

What happens to the pitch when frequency of a sound wave decreases?

It decreases by the same amount

It increases by the same amount

Which of the following changes will affect the speed of a wave through a medium?

A change in the material through which the wave travels

A change in the frequency of the wave

A change in the amplitude of the wave

The speed of a wave always remain the same regardless of the type of medium

A wave light is traveling from the air to water. What will happen to the speed of the light as it travels from one medium (Air) to the other medium (water)?

The light will slow down when it hits the water

The light will speed up when it hits the water

The speed of the light will remain the same

The wave of light is traveling from a glass medium to a water medium. What will happen to the speed of light?

The light will speed up when it hits the water

The light will slow down when it hits the water

The speed of light will remain the same

The picture demonstrates what?

The movement of electrons as they go from negative to positive poles

The movement of protons as they go from positive to negative poles

The movement of electrons as they go from positive to negative poles

As an astronaut travels from the surface of Earth to a position that is four times as far away from the center of Earth, based on the Law of Gravity which of the following statement is true?

Mass remains the same and the gravitational pull from Earth decreases

Mass decreases and the gravitational pull from Earth increases

Weight increases and the gravitational pull from Earth stays the same

Weight remains the same and the gravitational pull from Earth changes

What is the difference between mitosis and meiosis?

In mitosis, the products are identical to the parent cell, while in meiosis the products are different from the parent cells

Mitosis occurs in all of cells of plants and animals, while meiosis occurs in bacteria

In mitosis, one cell divides into two cells, while in meiosis two cells combine to make one cell

Mitosis involves separating the chromosomes, while meiosis only involves the cytoplasm of the cell
