MArishka [77]

Answer:

<u>Copper ( II ) chloride </u>

Explanation:

<em>According to the nomenclature , </em>

  • <em>The metal ion name is followed by the non-metal ion</em>
  • <em>The oxidation state of the metal is to be mentioned in the brackets .</em>
  • <em>As CuCl_{2} has two Cl^- ions , and the net charge on the compound is zero , the charge on copper is :</em>

Cu^{x}+2Cl^-=0\\x-2=0\\x=2+

thus ,

⇒Cu^{2+}

∴ ,

The proper nomenclature is :

Copper ( II ) chloride

Increasing the mass attached to a spring will decrease the angular frequency of its vibrations. True or False
Scrat [10]

Answer:

decreases

Explanation:

The angular frequency of the mass is given by

\omega =\sqrt{\frac{k}{m}}

where, k is the spring constant and m be the mass of the body which is doing oscillations.

if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.

g As observed on earth, a certain type of bacteria is known to double in number every 24 hours. Two cultures of these bacteria a
tangare [24]

Answer:

86.4 hrs

Explanation:

The amount of bacteria is initially 1

It doubles every 24 hrs.

After first 24 hrs, the amount = 2

After next 24 hrs = 4

After next 24 hrs = 8

After next 24 hrs = 16

After next 24 hrs = 32

After next 24 hrs = 64

After next 24 hrs = 128

After next 24 hrs = 256

Total time taken to reach 256 = 24 x 8 = 192 hrs

For the bacteria culture on the rocket that travels at a speed of 0.893c relative to the earth, this time is contracted by the relationship

t = t'(1 - ¥^2)^0.5

Where t is the contracted time =?

t' is the time on earth

¥ = v/c

Where v is the speed of the rocket

c is the speed of light

since v = 0.893c

¥ = 0.893

Substituting, we have

t = 192 x (1 - 0.893^2)^0.5

t = 192 x 0.2025^0.5

t = 192 x 0.45 = 86.4 hrs

Object A is negatively Charged. object A and Object B attract. Object B and Object C repel. Object C and Object D attract. What
3241004551 [841]

Remember opposites attract and same charges repel each other.

Object A= negatively charged.

Object A and B attract so B must be positively charged.

Object B and C repel so because B is positively charged C must also be positively charged.

Object C and D attract and because C is positively charged, D must be negatively charged.
