What is the current in a 160V circuit if the resistance is 5Ω?

Chemistry
2 answers:
oee [108]3 years ago
5 0

Answer:

use v=IR

Explanation:

so, 160=I*5

I = 160/5

=32 ampere

The current = 32 A

<h3>Further explanation</h3>

Electric current is a ratio between the voltage and the amount of resistance at the conductor.  

Can be formulated  

\large{\boxed{\bold{I=\frac{V}{R}}}

V = Voltage (volts)  

R = resistance (ohms)  

This formula is also known as Ohm's Law, which states that  

<em>the amount of current flowing is directly proportional to the voltage and inversely proportional to the resistance.</em><em>  </em>

<em></em>

V=160 V

R=5Ω

\tt I=\dfrac{160}{5}=32~A

During action potential, positively charged ________ ions move inside the cell.
Tems11 [23]

During action potential, positively charged  sodium ions move inside the cell.

So option D is correct one.

The sodium ion moves inside the cell during a action potential. The stage of action potential is called depolarization . This open voltage gated sodium channel.

Action potentials ( those electrical impulse that send signals around body )  is nothing but more than temporary shift ( from negative to positive ) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.

It consists of phases:

  • Depolarization
  • overshoot
  • repolarization

An active potential propagates along the cell membrane of an axon until  it reaches the terminal button.

2. Classify the following solutions as acidic, basic, or neutral at 25OC.
PilotLPTM [1.2K]

Answer: a) pH = 13.00 : basic

b) [H_3O^+]=1.0\times 10^{-12}: basic

c) pOH = 5.00 : basic

d) [OH^-]=1.0\times 10^{-9}: acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

pH=-\log [H_3O^+]

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

a) pH = 13.00

As pH is more than 7, the solution is basic.

b)  [H_3O^+]=1.0\times 10^{-12}

Putting in the values:

pH=-\log[1.0\times 10^{-12}]

pH=12

As pH is more than 7, the solution is basic.

c) pOH = 5.00

pH+pOH=14.0

pH=14.0-5.00=9.00

As pH is more than 7, the solution is basic.

d) [OH^-]=1.0\times 10^{-9}

Putting in the values:

pOH=-\log[1.0\times 10^{-9}]

pOH=9.00

pH+pOH=14.0

pH=14.0-9.00=5.00

As pH is less than 7, the solution is acidic.

How many electrons does an element have if its atomic number is 20
olga55 [171]

Answer:

20 electrons

A neutral atom with atomic number 20 will have 20 electrons.

The atomic number is, by definiton, the number of protons in an atom's nucleus but for a neutral atom it's also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.

How do you know something is there if you can't see it?
aliina [53]

Answer:

Explanation:

Use your other senses such as touch or smell, does it react in different temperatures, is it then visible under a microscope, does it react with different elements or gases?   Think outside the box.
