Answer:
The neck, Tongue, Heart and circulation and Lungs.
Explanation:
The Neck: The total length of the giraffe's neck is 6 feet and carries the muscles of about 550 pounds. But the unique characteristics is that it has same vertebrae as humans have i.e. 7. And to support these heavy muscles at the base of the neck spines are there projecting upwards.
The Tongue: Giraffe has a very avaricious long tongue that helps it to gets different vegetation.
Heart: Surprisingly the heart of the giraffe is small in structure yet powerful. And the blood pressure is quite high, double relatively to human so to pump the blood to its brain along with the long neck.
Okey so 1st find the moles of F2 which is :
n = 15/22.4 = 0.667mol
Then according to stoichiometric values, F2 and NaCl, they are to a ratio of 1 : 2
So take the twice value of the calculated moles.
Use the moles to find the mass using the equation :
m = n×M
Where m is the mass
n is moles
M is molar mass (of NaCl)
Therefore m = 1.334×57.5
(given the molar mass of Na 22gmol^-1 and CL 35.5gmol^-1)
m = 76.705g
Please be rightly informed that the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).
<h3>Fundamental quantities</h3>
These are quantities which forms the basic unit of measurement. The units of fundamental quantities are called fundamental units.
The three major fundamental quantities are:
Other fundamental quantities are:
- Temperature
- Amount of substance
- Magnetic flux
- Electric current
So therefore, the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).

Answer:
Frequency
Explanation:
When we talk about crests, we are referring to the high points of a wave.
We measure wave frequency by counting out the the number of crests (or high points) of a given wave that pass by a given point in a set amount of time. Thus, the higher the number of crests, the greater the frequency of the wave and vice versa.
We define the frequency of a wave as the number of waves that passes by a fixed point within a given period of time.
