Answer:

2.in columns

Explanation:

The elements of the periodic table is distribute as in 7 periods and 18 groups. The element is distribute on base on increasing atomic number.
The period is called horizontal row and the group is called vertical column.
in periodic number of sphere around the nucleus remain the same, but as we move from left to right, the valence electrons continue to increase.
so correct option is 2.in columns

Answer:

equal

Explanation:

If all three corresponding sides are equal and all three corresponding angles are identical in measure, two triangles are said to be congruent. These triangles can be slides, rotated, flipped and turned to be looked identical. If repositioned, they coincide with each other. The symbol of congruence is' ≅'.

Which of the following objects is in dynamic equilibrium?

Vera_Pavlovna [14]

a. A car driving in a straight line at 20 m/s.

Explanation:

An object is in a state of equilibrium when no force is acting upon it. There are two types of equilibrium; static equilibrium and dynamic equilibrium.

Static equilibrium is a state when a body is at rest.

Dynamic equilibrium is an equilibrium state when a body is moving at a constant velocity. (Rectilinear Motion).

A car moving in a straight line at 20 m/s has a constant velocity and hence no force is acting on it. So, it is in dynamic equilibrium.

A book sitting on a table without moving is not is dynamic equilibrium but in static equilibrium.

A boy jumping off a diving board in not in equilibrium as gravitational force is acting upon him and he has a changing velocity.

A motorcycle going in a circle at a constant speed has changing velocity because the direction of the motion is constantly changing hence it is not in the state of motion.

Keywords: velocity, force, equilibrium, static equilibrium, dynamic equilibrium

goldenfox [79]

Answer:

D) ¼ as large

Explanation:

The magnitude of the electric force between two charges is

$F=k\frac{q_1 q_2}{r^2}$

where

k is the Coulomb's constant

q1 and q2 are the magnitudes of the two charges

r is the separation between them

From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.

In this problem, the distance is doubled:

$r'=2r$

So the new force will be

$F'=k\frac{q_1 q_2}{(2r)^2}=\frac{1}{4}k\frac{q_1 q_2}{r^2}=\frac{1}{4}F$

So the force will decrease to 1/4 of its original value.
