Answer:
C. Electricity heats up the filament in the bulb to a very high temperature. At that temperature, the metal becomes bright and gives off light.
Explanation:
The incandescent light bulb turns electricity into light by sending the electric current through a thin wire called a filament. Electrical filaments are made up mostly of tungsten metal. The resistance of the filament heats the bulb. Eventually the filament gets so hot that it glows, producing light.

answer:
a.magma rises into the spaces where tectonic plates pull away from one another
explanation:
seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. the mid-atlantic ridge, for instance, separates the north american plate from the eurasian plate, and the south american plate from the african plate.
good luck :)

1. explain why mid-sized cars and SUVs have different rollover fatality rates.
2.explain why mid-sized cars and SUVs have the same fixed-object fatality rates.
Plz answer these questions im begging you to answer both will report if u only answer one.
Answer:
1: Their higher center of gravity increases their risk of rollovers. Their larger mass increases their braking radius, reduces visibility, and increases damage to other road users in collisions. Their higher front-end profile makes them at least twice as likely to kill pedestrians they hit.
2: In recent years automakers have reduced the threat SUVs and pickups pose by more closely aligning their energy-absorbing structures with those of cars. Fuel economy can be improved without sacrificing safety.

what characteristic of a wave is related to the intensity of loudness of a sound?
1. Amplitude
2. Frequency
3. Wavelength
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.

Does it take more force to accelerate a dump truck or a car from 0 m/s/s to 10 m/s/s? Explain.
Answer:
It takes more force to accelerate a dump truck
Explanation:
Because a dump truck has more mass so it would also have more friction and accelerate slower.

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.

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

1. explain why mid-sized cars and SUVs have different rollover fatality rates.
2.explain why mid-sized cars and SUVs have the same fixed-object fatality rates.
Plz answer these questions im begging you to answer both will report if u only answer one.
Answer:
1. They generally have poorer fuel efficiency and require more resources to manufacture than smaller vehicles, thus contributing more to climate change and environmental degradation. Their higher center of gravity increases their risk of rollovers.
2. Mid-sized cars and SUVs both have a fixed object fatality rate of 2.6/BVM. This is most likely because they have a similar mass and inertia. The force of the crash is likely to have about the same deceleration in both vehicles.

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
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.
If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?
The climate would get colder and drier as you go up the mountain.
The climate would get warmer and wetter as you go up the mountain.
The climate would stay the same because you are in the same climate zone.
The climate would be similar to a tropical climate zone as you go up the mountain.
Answer:
A is the anser
Explanation:
because as u go up the moutain u fell it getting more cold and dryer as u go up the moutain
The climate would get colder and drier as you go up the mountain. The correct option is A.
What is the effect of altitude on the atmosphere?The amount of gas molecules in the air decreases as altitude increases—the air becomes less dense than air closer to sea level. Thin air, as defined by meteorologists and mountaineers, exerts less pressure than air at a lower altitude.
The temperature drops as you ascend into the troposphere and mesosphere. The climate would get colder and drier as you go up the mountain.
Therefore, option A will be the correct answer for climate change.

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
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.

6. C: static electricity
The opposite charges stick to each other, a battery again is an example of this.

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.

Metamorphic
Volcanic
Igneous
Sedimentary
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.
