Answer:
30.24m
Explanation:
When adding numbers together, we round to the smallest number of decimal places of the numbers, which is 2 decimal places in this case.
24.686m + 2.343m + 3.21m = 30.23<u>9</u> m
≈ 30.24m (round to 2 d.p.)
When you round numbers to a certain digit (hundredth in this case), you would want to look on the digit on its right (thousandth in this case). If that digit is 1-4, you round the digit down. If that digit is 5-9, you round the digit up. Since the digit in the thousandths place is 9, you round the hundredth digit up from 3 to 4.

Image result for If the world was not tilted, what would happen to the people living on Earth
If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant

Answer:
IT and science courses
Explanation:
As Health Information Management department requires a person who should have fair knowledge about science and medical so that he/she can deal with the data extracted from diseases. He/she should also have fair knowledge about IT so that the person can manage the files and data very well. The data should be managed accurately so different IT programs help in completing this goal. IT knowledge will help to keep data safe, accurate and complete. Due to IT knowledge they can upgrade and redesign programs according to their need.
Answer:
(a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
Explanation:
Given that,
Refractive index = 1.20
Wavelength = 496 nm
Next wavelength = 386 nm
We need to calculate the thickness of the glass
Using formula for constructive interference
Put the value into the formula
In first case,
.....(I)
In second case,
.....(II)
From equation (I) and (II)
Put the value of m in equation (I)
The thickness of the glass is 868 nm.
(b). We need to calculate the wavelength
Using formula of constructive interference
Put the value into the formula
Hence, (a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
