The diagram shows a wave traveling through a medium. Identify point B.

Energy waves traveling at the speed of light are called _____.

RADIATION

There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles.<span>

A surface completely surrounds a 3.3 × 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphe

KengaRu [80]

Answer:

Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C

Explanation:

given,

surface charge (q) = 3.3 × 10⁻⁶ C

to calculate electric flux = ?

a) radius = 0.76 m

area of sphere = 4 π r²

electric flux = $\dfrac{q}{\varepsilon}$

$\varepsilon = 8.85 \times 10^{-12} C^2/Nm^2$

electric flux = $\dfrac{3.3 \times 10^{-6}}{8.85 \times 10^{-12} }$

flux = 0.373 × 10 ⁶ N m²/C

electric flux in the other two cases will also be same as electric flux is independent of area

so, Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C

two masses are kept 2 metre apart there is gravitational force of 2 Newton what is the gravitational force when they are kept at

sukhopar [10]

Answer: 0.5N

Explanation:

Gravitational force is calculated using the formula :

F = Gm1m2/r^2

Where G is the gravitational constant (6.67 × 10^-11)

At a distance 'r' of 2metres apart:

Mass of objects are m1 and m2

Gravitational force 'F1' = 2N

Inputting values into the formula :

2 = Gm1m2 / 2^2 - - - - - (1)

At a distance 'r' of 4meters apart:

Mass of objects are m1 and m2

Gravitational force 'F2' = y

Inputting values

F2 = Gm1m2 / 4^2 - - - - - (2)

Dividing equations 1 and 2

2 = Gm1m2 / 2^2 ÷ F2 = Gm1m2 / 4^2

2 / F2 = (Gm1m2 / 4) / (Gm1m2 / 16)

2 / F2 = (Gm1m2 / 4) × (16 / Gm1m2)

2/F2 = 16 / 4

Cross multiply

2 × 4 = 16 × F2

8 = 16F2

F2 = 8/16

F2 = 0.5N

Im stuck on this question, please help. :)

Pie

Light travels in waves, and light travels at about 3.0x10^8 m/s. and you call that this the 'speed of light' so your answer possible could be

A. It travels at the speed of light.

I might be wrong so double check.

Position (m)

Elina [12.6K]

Answer:

Image result for position (m) 80 60 40 20 - 20 -40 10 20 30 40 50 time (sec) What is the displacement from 15 to 40 sec? a 20 m b Оооо - 20 m -100 m с 100 m

The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
