Answer:

D

Explanation:

I think it is D. Think about it- if a human jumps, they are less than the gravitational force. But, if you are greater than the gravitational force, I think you will go into space.

34. Explain how dimensional analysis is used to solve<br> problems.
alisha [4.7K]

Answer: By understanding conversion factors and how they are related to each other

Explanation:

Dimensional Analysis is a step by step approach to solving problems in Physics, Chemistry , and Mathematics. It involves having a clear knowledge and understanding to be able to convert a given unit to another in the same dimension using  conversion factors and knowing how they are related to each other.

For instance, In Chemistry, we want to Convert 120mL to L.(note that ml stands for millilitres and ;L stands for litres)

Or first approach will be to write out the conversion factor related to our problem which is

1000ml =1L

such that 120ml = (we cross multiply))

giving us  120ml x 1L/1000ml =0.12L

This same process is applied to convert any type of dimensional analysis problems be it physics or mathematics.

Please help!!!!!!!!!!
STatiana [176]
Phosphorus - P - Protons = 15, Electrons = 15, Neutrons = 16 - Non-Metal

Lithium - Li - Protons = 3, Electrons = 3, Neutrons = 4 - Metal

Nitrogen - N - Protons = 7, Electrons = 7, Neutrons = 7 - Non-Metal

Copper - Cu - Protons = 29, Electrons = 29, Neutrons = 34 - Metal

Neon - Ne - Protons = 10, Electrons = 10, Neutrons = 10 - Non-Metal

sorry i don’t know about the other questions but i thought i could help with the table!

Additional Info:

number of protons = atomic number

number of electrons = atomic number

number of neutrons = mass number - atomic number

a solution of KCl in water has a concentration of 0.243 M. The solution has a volume of 0.580 L. How many grams of KCl are prese
Novosadov [1.4K]

Answer:

10.5 g

Explanation:

Step 1: Given data

  • Molar concentration of the solution (C): 0.243 M
  • Volume of solution (V): 0.580 L

Step 2: Calculate the moles of solute (n)

Molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

n = M × V

n = 0.243 mol/L × 0.580 L = 0.141 mol

Step 3: Calculate the mass corresponding to 0.141 moles of KCl

The molar mass of KCl is 74.55 g/mol.

0.141 mol × 74.55 g/mol = 10.5 g
