Find the equivalent resistance of this

Physics
1 answer:
frosja888 [35]3 years ago
7 0

Answer:

Re=160ohm

Explanation:

Step#1

Rt=R1+R2 ( because both are in series)

Rt=(100+220 ) ohm

Rt=320 ohm

Step#2

Rt and R3 are parallel so,

Re= (Rt× R3) ÷ (Rt+R3)

Re= (320×320)÷( 320+320)

Re = 102,400÷ 640

Re=160ohm

A car travels 240 miles south in 3 hours. find the velocity of the car in mi/hr and m/s
marshall27 [118]

We'll find the car's speed first, and then use that to find the velocity.

Speed = (distance covered) / (time to cover the distance)

Speed = (240 miles) / (3 hours)

Speed = (240/3) · (miles/hours)

Speed = 80 mile/hour

Now to convert the units, we'll use

-- 1 mile = 1,609 meters

-- 1 hour = 3,600 seconds

(80 miles/1 hour) · (1,609 meter/1 mile) · (1 hour/3,600 second) =

(80 · 1,609 · 1) / (1 · 1 · 3,600) (mile · meter · hour / hour · mile · second) =

35.76 meter/second

Now, to make a velocity, all we need to do is to add the direction to the speed.

So the car's <em>velocity</em> is <em>80 mi/hr south</em>, or <em>35.76 meter/sec south</em> .

What is Light ?<br> What are 7 spectrums of Light ?
kolbaska11 [484]

Answer:

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, between the infrared and the ultraviolet.

Here are the 7 from shortest to longest wavelength.

Violet - shortest wavelength, around 400-420 nanometers with highest frequency.  

Indigo - 420 - 440 nm.

Blue - 440 - 490 nm.

Green - 490 - 570 nm.

Yellow - 570 - 585 nm.

Orange - 585 - 620 nm.

Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency.

Which of the following is a measure of disorder or randomness
garri49 [273]

<u>Answer</u>:

D. Entropy is a measure of disorder or randomness

<u>Explanation</u>:

The answer is entropy. It is the method to measure any disorder or randomness of any system. Basically it is concept of physics and chemistry but can also be used in other subject matters as well. In formula terms, it is denoted by S and is measurement value is "Joule per kelvin". The values could be both positive and negative as well.

All the other options are incorrect as heat, energy and temperature are the different concepts of science which do not relates with any measurement.
