Hurricanes are predicted using a Saffir-Simpson Scale. This scale is used to measure the intensity of hurricane most often than not. However, it may be used to identify a hurricane as well. A hurricane is categorised based on the wind speeds.
74 - 95 mph --> category 1
96 -110 mph --> category 2
111 - 129 mph --> category 3
130 - 156 mph --> category 4
157 mph + --> category 5
Typically, the formation of a hurricane occurs when moist warm air if absorbed from the Atlantic or Pacific Ocean and rises. The moisture will then evaporate further rising and heating until the moist air is twisted and circulation high in the atmosphere.
Answer:
1. Polytheism 2. Monotheism
Explanation:
from Greek πολυθεϊσμός, polytheismos) is the worship of or belief in multiple deities, which are usually assembled into a pantheon of gods and goddesses, along with their own religions and rituals.Monotheism is the belief in one god. A narrower definition of monotheism is the belief in the existence of only one god that created the world, is all-powerful and intervenes in the world.hope this helps ♡
Purdah or pardah (from Persian: پرده, meaning "curtain") is a religious and social practice of female seclusion prevalent among some Muslim and Hindu communities in South Asia.[1] It takes two forms: physical segregation of the sexes and the requirement that women cover their bodies so as to cover their skin and conceal their form. A woman who practices purdah can be referred to as pardanashin or purdahnishan.
Answer: the answer is D i think
Explanation:
The doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the detector.
Doppler effect in light is actually a relativistic effect (caused due to relativistic time dilaton and can be explained by special theory of relativity) but somewhat similar to the one which happens in sound waves. This effect has nothing to do with the bending in spacetime.
When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector (think of a wave being stretched), as a result the frequency decreases (since, speed of light is constant in all frames). Due to this decrease in frequency the light emitted from the source appears more red (since red color is on low frequency side in the electromagnetic spectrum) compared to the situation when source was at rest.
Vice versa for the source moving towards the detector
This shift in frequency is also known as doppler shift.
The shift in frequency when the source is moving away is known as redshift and the opposite one is known as blueshift.
