The answer is 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Given,
The center of the school's basketball team is 6 ft 10 inches tall.
We have to convert the height of the player from feet and inches to feet.
Using the conversion factor,
1 ft = 12 inches
or, 12inches/ 1 ft
Converting 6ft 10 inches to ft, we get;
10 inches × 1 ft/ 12inches
= 0.833 ft
Therefore 6 ft 10 inches in millimeters (mm) is 0.833 ft.
Unit conversion is a method in which we multiply or divide with a particular numerical factor and then finally round off to the nearest significant digits.

#SPJ4
Answer:
Explanation:
3.
Knowns: 100mL of solution; concentration of 0.7M
Unknown: number of moles
Equation: number of moles = volume * concentration
Plug and Chug: number of moles = 100/1000 * 0.7 = 0.07 mole
Final Answer: 0.07mole
2.
Knowns: 5.50L of solution; concentration of 0.400M
Unknown: number of moles
Equation: number of moles = volume * concentration
Plug and Chug: number of moles = 5.5 * 0.4 = 2.20 mole
Final Answer: 2.20 mole
Answer:
FALSE
Since 0.385 < 0.526, the value for week 3 is accepted.
Explanation:
Qexp = (|Xq - Xₙ₋₁|)/w
where Xq is the suspected outlier; Xₙ₋₁ is the next nearest data point; w is the range of data
First, the data are arranged in decreasing order, from highest to lowest:
3. 5.6
2. 5.1
8. 5.1
1. 4.9
6. 4.9
5. 4.7
7. 4.5
4. 4.3
Xq = 5.6; Xₙ₋₁ = 5.1; w = 5.6 - 4.3 = 1.3
Qexp = (|5.6 - 5.1|)/1.3 = 0.385
From tables, at 95% confidence level, for n = 8, Qcrit = 0.526
Since 0.385 < 0.526, the value for week 3 is accepted.
Van der waals force
Explanation:
The intermoleclular forces are attraction between molecules. Interatomic forces are attraction between atoms in a compound.
In most hydrocarbons the weak Van der waals attraction are known.
- These forces are weak attraction joining non-polar and polar molecules together.
- These forces can also be found in layers of graphite.
- They are of two types;
London dispersion forces are attraction that exists between non-polar molecules and the noble gas.
Dipole - Dipole attractions are forces of attraction existing in polar molecules.
In hydrocarbons, we have non-polar molecules and intermolecular attraction is london dispersion forces.
