Answer: If the Sun had an even greater mass then it currently does, it would have a larger gravitational pull and since it's heat would be closer to Earth, both by magnitude and gravity, life on Earth wouldn't be possible and life on Mars would be reality. Also, when the sun would explode, it would have a larger supernova and possibly create a white dwarf (something that only happens to red supergiant stars when they die), with a gravitational force so strong it wold have two beams of light coming out it's north and south poles (like a black hole).
I hope this helps!
Answer:
Electricity is made at a generating station by huge generators. The current is sent through transformers to increase the voltage to push the power long distances. The electrical charge goes through high-voltage transmission lines that stretch across the country.
Answer:
Temperature and volume are directly related.
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure. :)
Time t=2.4 minutes=2.4×60=144 seconds
distance s=1.2 miles=1.2×1609=1930.8 meters
speed v=s/t=1930.8÷144=[tex] \frac{1930.8}{144} = \frac{160.9}{12} =[/13.408m/s ~nearly]
Answer:
1. light is made up of energy
2. light travels in a straight line
3. the speed of light is exactly 299 792 km per second
4. this is the speed when light is traveling in a vacuum and not obstructed by the atmosphere 5. traveling at the speed of light you could go around the earth seven and a half times in a second
6. light can move super fast super slow and not at all
7. we can use light to weigh Stars
8. we can use light as tweezers
9. bubbles can turn sound into light
10. lasers can make things cold
