Which are electromagnetic waves? Check all that apply.

Scrat [10]

Answer:

infrared waves

radio waves

ultraviolet waves

Explanation:

Radio waves are used for communication such as television and radio.

Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark.

Ultraviolet radiation can kill bacteria that are present in water - this sterilises the water and makes it safe to drink.

At what distance (in m) is the electrostatic force between two electrons equal to the weight of one?

Ksivusya [100]

Answer:

Explanation:

Given

Electrostatic force between two electrons is equal to weight of one electron

i.e.

$\frac{kq_1q_2}{r^2}=m_e\cdot g$

where $q_1,q_2$ are the charge of particles

$m_e=$ mass of electron

r=distance between them

$\frac{9\times 10^{9}\times 1.6\times 10^{-19}\times 1.6\times 10^{-19}}{r^2}=9.11\times 10^{-31}\times 9.8$

$r=5.08\ m$

Hi people; there's a question that has been so confusing for me and a friend of mine.

Alborosie

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

$y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32$

In our case x = 0, then y will be:

$(0^{\circ}C * \frac{9}{5})+32=32$

$y=32^{\circ}F$

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

$0^{\circ}C+0^{\circ}C=32^{\circ}F$

I hope it helps you!

What is the colour of third band of a coded resistor having resistance equal equal to 2.3*10`2

Helen [10]

Color of third band of a coded resistor is Brown.

What is Resistance:

Resistance is a measure of the opposition to current flow in an electrical circuit.
Resistance is measured in ohms, omega (Ω)

The color code specify the resistance value, the tolerance, and sometimes the reliability or failure rate.

How to identify resistor's color codes:

Look at the resistor so the group of 3 or 4 color bands are on the left side
Read the color bands from left to right.
Read the color on the last color band, which is farthest right.
compare the colors to the resistance code table

Here,

the value of resistance is 2.3x10^2 Ω

R = 23x10^1 Ω

here power of 10 is 1

so, the color of third band of a color coded resistor will be related to number 1

Hence,

color of third band of a coded resistor is Brown.
