To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.
He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.
A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.
Answers
Answer:
Black Final: 38; Change: 16
White Final: 24; Change: 2
Green Final: 29; Change: 7
Red Final: 31: Change: 9
Blue: 33: Change: 11
Explanation:
Black Final: 38
Black Change: 38 - 22 = 16
White Final: 24
White Change: 24 - 22 = 2
Green Final: 29
Green Change: 29 - 22 = 7
Red Final: 31
Red Change: 31 - 22 = 9
Blue Final: 33
Blue Change: 33 - 22 = 11

An object with little mass won't require a lot of force to move.
Group of answer choices
A. False
B. True
C. Only sometimes
Answers
Answer:
True
Explanation:
Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.

Answers
Answer:
sedimentary i think
Explanation:
Answer:
Rock A sedimentary
Rock B Metamorphic
Explanation:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

The others dont make sense for energy.
2. C: Lamp
A lamp uses the electric current to light up a room, or area.
3. B: foil will bend away
The same charges repel each other that is why a magnet is repelled by the same pole of another magnet.
4. A: Sound
You can’t hear light or any of the other options.
5. A: gravity
Gravity is a force of nature that pulls on everything.
6. C: static electricity
The opposite charges stick to each other, a battery again is an example of this.
7. B: a copper nail
Metal is one of the best electric conductors.
8. C: closed circuit
This is because if a circuit is closed the electricity flows through perfectly but for example an open one would not work or it would leak energy.

what characteristic of a wave is related to the intensity of loudness of a sound?
1. Amplitude
2. Frequency
3. Wavelength
Answers
Th characteristic of a wave related to the intensity of loudness of a sound is amplitude. Amplitude is a measure of the intensity of waves.
What is amplitude of a wave ?Amplitude of a transverse wave is the height to the crest or trough from the base line. Amplitude of a wave is directly proportional to its frequency. Amplitude is measure of intensity of the wave.
Sound waves are longitudinal waves. Longitudinal waves are composed of compressions and rarefactions. The amplitude of a sound wave is the distance between the particles in compressions.
Amplitude is a frequency depended factor. As the frequency increases, amplitude of the wave also increases, making the wave energetic and sound louder. Hence, option 1 is correct.

Write a scientific explanation that explains the most likely reason why Mercury and Venus do not have moons. CER.
Due in 1 hour pls helppppp
Answers
Answer:
Mercury and Venus do not have moons. This is because any moon orbiting around them would be in an unstable orbit and would most likely be swallowed by the mammoth gravitational pull of our solar system’s mighty Sun. Whenever we look up at the night sky, we see a greyish-white object hung brightly among thousands of other visible stars.
Answer:
Most likely because they are too close to the Sun. Any moon with too great a distance from these planets would be in an unstable orbit and be captured by the Sun. If they were too close to these planets they would be destroyed by tidal gravitational forces.
