Edwin Hubble used the Doppler effect to determine that the universe is expanding. After years of scientific research and observation of different celestial bodies through a telescope, Hubble found that the light from distant galaxies was shifted towards the red end of the spectrum. This red shift indicates that stars are moving away from us and from each other. This phenomenon is called the 'expansion of the universe', also known as the big band theory.
Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.
Answer:
Object A but not object B
Answer:
550 milliliters of water is needed.
Explanation:
the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
