The ONLY way to change the volume of a sample of gas is to transfer it to a container with different volume.
Simply changing its temperature or pressure in the same jar won't do it. Any amount of gas always fills whatever container you keep it in.
I say that the answere would be B
Answer:
Explanation:
The speed of light is 3.0 x 10⁸ m/s
We need to find the distance traveled by it in one day.
1 day = 24 hours
1 day = 24 × 3600 seconds
= 86400 s
Now, using the formula of speed to find the distance covered as follows :
Putting all the values, we get :
Hence, light will cover of distance in one day.
Answer:
Technically, humans are causing global warming.
Explanation:
There's some research done into this (sadly not enough), some of which can be found here, https://www.nationalgeographic.com/environment/global-warming/global-warming-causes/ and here, https://climate.nasa.gov/causes/ . The basics are as follows: Earth is a greenhouse. Sunlight comes towards us, and while some is reflected out, most is absorbed through greenhouse gasses, like Carbon Dioxide. Because of humanity, the amount of carbon dioxide in the air has increased, leading to more warmth from the sun to be absorbed. Therefore, the earth is getting warmer because of us.
