B. eating the right amount of calories each day
for a, you need proteins,veggies and calories to survive, as each does a specific job such as glucose and protein being created, etc.
For c, you can have at least 1 item from each food group each day, but you can still have too much of something and thats harmful.
For d,getting 100% calcium only works with calcium, and you can do anything with the other foods.
For b(which is correct), people usually eat an excess of calories, and that mainly controls your weight. Now other food groups can also affect you if you have too much, but people tend to have too much calories, so getting the right amount of calories is the best choice

Consider the following types of electromagnetic radiation:

liq [111]

Explanation:

Electromagnetic wave Wavelength

(1) Microwave = 1 m to 1 mm = $10^9 nm$ to $10^6 nm$

(2) Ultraviolet = 10 nm to 400 nm

(3) Radio waves = 1 mm to 100 km = $10^6 nm$ to $10^{14}nm$

(4) Infrared = 700 nm to 1 mm

(5) X-ray = 0.01 nm to 10 nm

(6) Visible = 400 nm t0 700 nm

a) In order of increasing wavelength:

: 5 < 2 < 6 < 4 < 1 < 3

b) Frequency of the electromagnetic wave given as:

$\nu=\frac{c}{\lambda }$

$\nu$ = frequency

$\lambda$ = Wavelength

c = speed of light

$\nu \propto \frac{1}{\lambda }$

So, the increasing order of frequency:

: 3 < 1 < 4 < 6 < 2 < 5

c) Energy(E) of the electromagnetic wave is given by Planck's equation :

$E=h\nu$

$E\propto \nu$

So, the increasing order of energy:

: 3 < 1 < 4 < 6 < 2 < 5

What are fluids? Why are they so called?

navik [9.2K]

Answer:

Liquids and gases are called fluids because they can be made to flow, or move.

 In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container. So that they're called fluids.
