Explanation:
Given mass of the object is 1200kg and it's placed at a height of 45m above the ground. As we know that potential energy is ,
where,
- m is the mass of the body .
- g is acceleration due to gravity.
- h is the height above the ground .
Substituting the respective values ,

Multiply ,
<u>Hence</u><u> the</u><u> </u><u>potential</u><u> energy</u><u> is</u><u> </u><u>5</u><u>4</u><u>0</u><u>0</u><u>0</u><u>0</u><u>J</u><u> </u><u>.</u>

1. Alpha
Number next to Th is 231
(because 231 + 4 = 235)
The other number below the 4 is 2 - helium
(because 90 + 2 = 92)
2. Beta
Missing numbers are zero and one. Same as the one below it.
3. Beta
11 is the number above the C
(because 11 + 0 = 11)
5 is the number next to the B
(because 5 + 1 = 6)
Basically, the missing numbers must balance on both side of the equation; creating the elements you've started of with, meaning if you where to add the right side of the equation up - you should end up with the same protons and mass numbers you began with.
Hope this helps!
Answer:
All 3 are CSS unit sizes which we can use for margins, fonts, borders etc.
Exp
CSS has four different unit sizes. These are:
Pixels (px)
Points (pt)
Ems (em)
Percentages(%)
These units are divided into two different groups. They are fixed and relative.
Pixels and points are fixed , whereas em and percentages are relative unit sizes. Relative unit sizes are good when creating scalable layouts.
Ems (em):
An em is a CSS unit that measures the size of a font. Originally, the em was equal to the width of the capital letter M, which is where its name originated.
It stands for "emphemeral unit" which is relative to the current font size.
The "em" is a scalable unit that is used in web document media. Ems have mobile-device-friendly nature.
Pixels (px):
Pixels are fixed-size units that are used in screen media. One pixel is equal to one dot in computer. The problem with pixel unit is that it is not relative .
Points (pt):
Point values are only for print. A point is a unit of measurement use for real-life ink on paper. Generally, 72pts= 1 inch which is one real-life inch like on a ruler. Point is not recommended to use in web pages.
Generally, 1em=16px=12pt=100% if the body size is 100%.
Relative unit sized fonts change and fixed unit sized fonts remain the same.
For example,
body { font-size: 100%}
p{font-size: 16px}

La velocidad del sonido en el aire (a una temperatura de 20 ºC) es de 343 m/s. La ecuación creada por Newton y posteriormente modificada por Laplace que permite obtener la velocidad del sonido en el aire teniendo en cuenta la variable de la temperatura es "331+(0,6 x Temperatura)".
