Answer:
44.71 mi/h
11.17 mi
Explanation:
To express the velocity in the S.I. you use the following equality:
then, by replacing you obtain:
When the car has traveled while 15 minutes you have:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
TRANSLATION:
Para expresar la velocidad en el S.I., utiliza la siguiente igualdad:
entonces, al reemplazar, obtienes:
Cuando el automóvil ha viajado durante 15 minutos, tiene:
Nickel = Ni
It's # 28 in the periodic table and it's Atomic Weight is 58.69
To solve this problem it is necessary to apply the concepts related to pressure as a unit that measures the force applied in a specific area as well as pressure as a measurement of the density of the liquid to which it is subjected, its depth and the respective gravity.
The two definitions of pressure can be enclosed under the following equations
Where
F= Force
A = Area
Where,
Density
g = Gravity
h = Height
Our values are given as,
If we make a comparison between the lid and the tube, the diameter of the tube becomes negligible.
Matching the two previous expressions we have to
Re-arrange to find h
Therefore the height of water in the tube is 7.9cm
