Which best describes the electric field created by a positive charge?

Physics

Aloiza [94]3 years ago
5 0

Answer:

Its rays point away from the charge.

Explanation:

The electric field due to a point charge is given by :

E=\dfrac{kq]{r^2}

Where

k is the electrostatic constant

q is the point charge

r is the distance from charge particle

It is clear that the electric field is directly proportional to the charge and inversely proportional to the distance from charge particle.

There are two types of charged particle i.e. negative and positive charge. For a positive charge, the direction of electric field points away from it and for a negative charge, the direction of electric field points towards it.

Hence, the correct option is (c).

Electron grops could be considered which of the following
Maurinko [17]

Answer:

Electron groups could be considered as  Lone pair electrons and bonded pairs of electrons.

Answer: Option D & B

Explanation:

The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.

If a rock is dropped from the top of a tower at the front of it and takes 3.6 seconds to hit the ground. Calculate the final vel
expeople1 [14]

Answer:

35.28m/s; 63.50m

Explanation:

<u>Given the following data;</u>

Time, t = 3.6 secs

Since it's a free fall, acceleration due to gravity = 9.8m/s²

Initial velocity, u = 0

To find the final velocity, we would use the first equation of motion;

V = u + at

Substituting into the equation, we have;

V = 0 + 9.8 * 3.6

V = 35.28m/s

Therefore, the final velocity of the penny is 35.28m/s.

To find the height, we would use the second equation of motion;

S = ut + \frac {1}{2}at^{2}

Substituting the values into the equation;

S = 0(3.6) + \frac {1}{2}*9.8*(3.6)^{2}

S = 0 + 4.9*12.86

S = 0.5 *36

S = 63.50m

Therefore, the height of the tower is 63.50m.
