Explain the process on how the conditions for lightning to strike occurs?

Answers

Answer 1
Answer: "A cloud-to-ground lightning strike starts as a channel of negative charges makes its path towards the ground. This occurrence is known as a stepped leader. The stepped leader continues towards the ground in a series of steps that are each about 50 to 100 metres in length. This stepped leader can branch out in many directions. A lightning strike refers to as a lightning flash, is usually made up of more than one stroke of lightning. After the initial strongest stroke, subsequent weaker strokes can follow which usually (but not always) follow the same path of the initial stroke. "

0.5 grams of sodium chloride is dissolved to make 0.05 liters of solution. How do I solve this?

Answers

The concentration of the solution has been 0.17 M.

The molarity has been defined as the moles of solute that has been dissolved in a liter of solution. The molarity of the solution has been expressed as:

\rm Molarity=(Mass)/(Molar\;mass)\;*\;(1)/(Volume\;(L))

Computation for Molarity of the solution

The molar mass of sodium chloride solution has been 58.5 g/mol.

The given mass of NaCl in the solution has been 0.5 grams.

The volume of NaCl solution has been 0.05 L.

Substituting the values for molarity of the solution:

\rm Molarity=(0.5)/(58.5)\;*\;(1)/(0.05\;L)\n\nMolarity=0.17 M

The concentration of the solution has been 0.17 M. The solution has been prepared by dissolving 0.5 g NaCl in minimal water, and makeup the volume to 0.05 L.

If you are trying to find the molarity of this solution you first need to find the number of moles of sodium chloride that are present in the 0.5g sample.  To do this you need to divide the mass of sodium chloride (0.5g) by its molar mass (58.45g/mol) to get 0.00855mol of sodium chloride.  Then you divide the number of moles (0.00855mol) by the volume of solution (0.05L) to get 0.171M (The units for molarity is mol/L).  Therefore the solution has a concentration of 0.171M.

A balloon is a sphere with a radius of 5.0 m. The force of air against the walls of the balloon is 45 N. What is the air pressure inside the balloon? (surface area = 12.56 x radius^2; 1 Pa = 1 N/m^2)A. 1.4 x 10^3 Pa

B. 3.6 x 10^2 Pa

C. 1.4 x 10^-1 Pa

D. 3.6 x 10^-2 Pa

***Idk how to solve this... pls explain?? thx :)

Answers

Pressure is the force exerted on an object per unit area. The equation is expressed as:

P = F / A

From the given above, we substitute the values to the equation.

P = F/A
P= F / (12.56r²)
P = 45 N / (12.56 x 5²
P = 0.143 N/m²

Therefore, the correct answer is option C, 1.4 x 10^-1 Pa.
