A) c = 3 x 10^8 m/s 
f = 7.15 x 10^14 Hz 
c = λ x f (=) λ = 3 x 10^8 / 7.15 x 10^14 = 4.19 x 10^-7 m = 419.6 nm 

B) E = h  f 
H = Planck's constant = 6.63 x 10^-34 J/s 
E = 6.63 x 10^-34 x 7.15 x 10^14 = 4.74 x 10^-19 J

magine that an uncharged pith ball is brought into the electrostatic field of a charged rod. The side of the pith ball closest t
ivanzaharov [21]
Answer: option <span>D. be given a positive charge produced by the movement of electrons to the other end of the ball.
</span>

Explanation:


This phenomenon is called electrostatic induction.


The excess of negative charge on the end of the rod will repel the electrons on the side of the pith ball that have been approached to it.

Then the electrons on the pith ball will move far away from this end with it will be left an excess of positive charge.

In this way the rod has induced that the ball acquires a positive charge on one end and a negative charge on the other end.

What is the molarity of a solution formed when you add 200. Ml of water to 50. Ml of 5. 0 m hcl
Gnesinka [82]

The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.

<h3>How to calculate molarity?</h3>

The molarity of a solution can be calculated using the following formula:

M1V1 = M2V2

Where;

  • M1 = molarity of a base
  • M2 = molarity of acid
  • V1 = volume of base
  • V2 = volume of acid

M1 × 200 = 50 × 5

200M1 = 250

M1 = 250/200

M1 = 1.25M

Therefore, the molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
