Light ... and all other forms of electromagnetic radiation ... behaves
as if it were a stream of 'packets' that we call 'photons', each one
carrying a specific amount of energy.

Light  ... and all other forms of electromagnetic radiation ... is
characterized by its wavelength.  That is, once you state its wavelength,
you've stated everything there is to know about the light, including its
frequency, and the energy carried by each photon.

What is the amount of electric field passing through a surface called? A. Electric flux.B. Gauss’s law.C. Electricity.D. Charge
rjkz [21]

Answer:

A. Electric flux

Explanation:

Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.

Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1.

(20 points) Pressure is a measure of force per unit area or P=F/A. A student is checking the amount of pressure their car exerts
Gala2k [10]

Answer:

35.2 ps

Explanation:

Hello!

A US short ton is equal to 2 000 pounds, therefore:

2.25 tons = 4500 pounds

Now lets convert the area of each tire footprint:

1 cm = 0.393701 in

12.5 cm = 4.92126 in

16.5 cm = 6.49607 in

Therefore, the area of the footprint is:   31.9688 in^2

Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :

4500 /(4 * 31.9688)  psi = 35.1906 psi

Rounding to the first tenth

35.2 psi

If the density of a diamond is 3.5 /cm^ 3 what would be the mass of a diamond whose volume is 0.5 cm ^ 3 ?
Elan Coil [88]

Answer:

1.75g

Explanation:

Given parameters:

Density  = 3.5g/cm³

Volume  = 0.5cm³  

Unknown:

Mass of the diamond  = ?

Solution:

Density is the mass per unit volume of a substance

  Density  = \frac{mass}{volume}  

So;

  Mass  = 3.5 x 0.5  = 1.75g
