Option a; Electric field can accelerate an electron, but never change its speed

An electric field (also known as an E-field) is a physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It can also refer to the physical field of a charged particle system. Electric fields are created by electric charges and time-varying electric currents. Electric and magnetic fields are both aspects of the electromagnetic field, one of nature's four fundamental interactions (also known as forces). Electric fields are significant in many areas of physics and are used in electrical technology. In atomic physics and chemistry, for example, the electric field is the attractive force that holds the atomic nucleus and electrons together in atoms. It is also the driving force behind chemical bonds between atoms.

In a 2-dimensional coordinate system, which of these is an example of an object's position?
Serjik [45]

' B ' is the only choice on the list that tells you a definite place, where you could go to pick up the object or meet somebody.

But in order to use it, you also have to know where the origin of coordinates is ... the point (0, 0) .

__________

No, I'm wrong about that.  You have to know where SOME other point is, but that doesn't have to be (0, 0).

A quantity of N2 occupies a volume of 1.4 L at 290 K and 1.0 atm. The gas expands to a volume of 3.3 L as the result of a change
lions [1.4K]

Answer:

\rho = 0.50 g/L

Explanation:

As we know that

PV = nRT

here we have

P = 1.0 atm

P = 1.013 \times 10^5 Pa

so we have

V = 1.4 \times 10^{-3} m^3

T = 290 K

now we have

(1.013 \times 10^5)(1.4 \times 10^{-3}) = n(8.31)(290)

n = 0.06

now the mass of gas is given as

m = n M

m = (0.06)(28)

m = 1.65 g

now density of gas when its volume is increased to 3.3 L

so we will have

\rho = \frac{m}{V}

\rho = \frac{1.65 g}{3.3 L}

\rho = 0.50 g/L

Determine the number of ways the faces of a regular tetrahedron can be colored with three colors
GREYUIT [131]
Tetrahedron is a geometrical figure or solid that is formed in similar manner as a pyramid. The faces of the formed pyramid are triangles. Also is the base. 

By the statement above, it can be deduced that the figure has four sides. The number of ways in which the sides can be colored by any of the three (3) colors is,
             3 x 3 x 3 x 3 = 81

Since the sides can still have the same colors, we deduct this value by 3 in order to eliminate the uniform colors of the four sides.
             = 81 - 3 = 78

Also, we can eliminate the concern on only two colors can mix,
              = 3 x 2 = 6
 Subtracting,
                      78 - 6 = 72

Hence, the answer is 72.
