Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations?
A Since glass is translucent, most of the light energy was reflected from the glass.
B When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.
C The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
D The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
Answer:
nope it is not c
Explanation:
Match the terms
1.the total energy of any closed system, including all internal kinetic and potential energy of the system
2.a measure of the average kinetic energy of particles in an object
3.something that flows into a substance
Terms-
Temperature
Heat
Thermal Energy
Answer:
1-thermal energy, 2-tempurature, 3-heat
Explanation:
The correct match of the terms and their definitions are:
1. Thermal energy – the total energy of any closed system, including all internal kinetic and potential energy of the system.
2. Temperature – a measure of the average kinetic energy of particles in an object
3. Heat – something that flows into a substance
What is thermal energy?Thermal energy is the energy that is formed by heat. It is produced when the temperature of a body increases. This cause the molecules and atoms to run or move fast or collide with each other.
Heat is a form of energy that is produced when the temperature of a substance increases. Heat, thermal energy, and temperature are interconnected to each other.
When the temperature rises, the heat or thermal energy in the body increase, which cause the movement of atoms faster, and the atoms collide with each other.
Thus, the correct match is 1- thermal energy, 2- temperature, and 3- heat.

Help I need to know and please answer three of the following questions
Answer:
we'll, metal cups are usually used for coffee so people who bring their coffee to work from home can keep it warm. metal cups however do not keep things cold, it may feel cold on the outside, but that's an illusion. plastic doesn't do much, its just a cold insulator. it is good at keeping things cold because it is a poor heat conductor. foil can keep things warm, but it can also keep things cold. do what you will with the info lol.
Answer:
1.H & E
Explanation:
metal cups keep things hot and cup H is made to keep things both cold and hot but the other cups will melt if you put hot stuff in them and number three is an answer it your self because it says to enter your answer so........

In two or more complete sentences explain how to balance the chemical equation,
Ca + N2 ⟶ Ca3 + N2 and include all steps.
Answer:
to balance this equation, your going to put a 2 in front of the "Ca" then that makes the equation look like this "2Ca + N2 ⟶ Ca3 + N2" since the "Ca" had one atom, we added two more atoms
as we all know 1 + 2 = 3
then that gives us 3 "Ca's" on both sides

How does the amount of water in a glass affect the pitch of the sound it produces?
Answer:
the more water the higher the pitch the less water the lower it is
Answer:
The glass with the most water has the lowest pitch. The glass with the least amount of water has the highest pitch.
Explanation:Tapping the glasses causes the air to vibrate. When the air column is shorter, the air vibrates faster and the pitch is higher.
Jim ran 200 meters in 30.4 seconds. Mac ran 100 meters in 30.4 seconds. Who ran faster?
Jim, because his distance divided by time is less
Jim, because he ran a greater distance in the same time

What is a diaphragm? What does it do?
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.
Explanation:
Diaphragm contracts and expands when you breathe air
Answer:
A diaphragm on a microscope is the piece that enables the user to adjust the amount of light that is focused under the specimen being observed. A diaphragm is typically found on higher-power microscopes versus less expensive or toy models. The diaphragm is located directly under the stage or platform where user places the specimen or slide.

Match the part of the wave to its description
Answer:
Crest Highest Point of the wave
Trough Lowest Point of the wave
Amplitude the height from mid point to the crest or trough
Wavelength Distance from one crest to another
The match of the wave is
Crest ⇒ Highest point of the wave.
Trough ⇒ Lowest point of the wave.
Amplitude ⇒ Height from mid point to the crest or trough
Wavelength ⇒ Distance from one crest to another.
What is wavelength?Wavelength the distance a wave travels in the time it takes a medium particle to complete one vibration. The letter k stands for it. The meter is its SI unit.
What is amplitude?
Amplitude can be referred to as the maximum displacement caused by the vibrating particle. A is the symbol for it. The meter is its SI unit.

Which of Newton's 3 Laws explains a rocket lifting off? *
Law of inertia
Law of Acceleration
Law of Action-Reaction
Answer:
Newton's Third Law of Motion
Explanation:
A rocket expels hot gases at a very high pressure very quickly, and these gases have lots of energy, and according to Newton's third law, every action has an equal and opposite reaction. So, expel lots of gas at a high rate, and the energy of the gases being pushed out propels the rocket upward. Hope that helps!
