Answer:

21.89 g

Explanation:

i = 15 A

time = 80 minutes = 80 x 60 = 4800 second

Electro chemical equivalent of nickel, Z = 0.000304 gram per ampere second

Use the Faraday's law of electrolysis

m = z i t

where, m is the mass deposited, i be the current, z be the electro chemical equivalent and t be the time taken

m = 0.000304 x 15 x 4800

m = 21.89 g

Thus, the mass f nickel deposited is 21.89 g.

A river flows due south at 5 mi/h. A swimmer attempting to cross the river heads due east swimming at 3 mi/h relative to the wat
Dafna11 [192]

Answer:

<u>velocity of swimmer relative to ground = 3 i -5 j</u>

Explanation:

  • To cross a river the swimmer swims relative to river in perpendicular direction.

Velocity of river = -5 j (south)

Velocity of swimmer relative to river = 3 i(north)

So

<h2>Velocity of swimmer relative to ground = Velocity of swimmer relative to river + Velocity of river</h2>

Velocity of swimmer relative to ground = 3 i -5 j

So magnitude of total velocity is \sqrt{3^2+(-5)^2} =\sqrt{9+25} = \sqrt{34}

A multi-dimensional being reaches down to Earth and pulls you out of the universe. You are then thrown back into the universe at
Shkiper50 [21]

You are in an early universe.

In the study of the evolution of the universe, it has been determined before Plank time (before the big bang and right after it), the early universe had the following characteristics:

  • There was only one single force acting over all that existed.
  • The early universe was very hot and dense because all matter had contracted before the big bang.
  • Space and time were wrapped.

These characteristics match the ones described, based on this, we can conclude you are in an early universe.
