Answer: be found in group 17 and be highly reactive

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.

Flourine, chlorine, bromine and iodine are elements which belong to Group 17. All of them contain 7 valence electrons each and need one electron to complete their octet.

The chemical reactivity of elements is governed by the valence electrons present in the element and thus all of them are highly reactive.

The answer would be conformity. This is a kind of social influence concerning a change in belief or conduct so one can fit in with a group. This alteration is in reply to real (physical occurrence of others) or fictional (pressure of social norms / prospects) group pressure.

Two metal balls are the same size, but one weighs twice as much as the other. The balls are dropped from the top of a two story
seropon [69]

The time taken by the metal balls of the same size but different weight, to reach the ground will be the same.

Reason behind:

Two metal balls are the same size, but one weighs twice as much as the other. The balls are dropped from the top of a two-story building at the same instant of time. It is required to find the time taken by the balls to reach the ground.

In free fall, all objects experience the same acceleration owing to gravity when they are close to the earth.

g=9.8 \text{ m/s}^2 is the measure of gravitational acceleration.

Because of this, the two metal balls are the same size but have different masses. The air resistance for both balls will be the same due to their similar sizes. Let, g' be the acceleration in the presence of air resistance. The balls are both discharged at once.

From a height of h, both balls descend due to gravity G'.

Therefore, the time taken by both balls is:

\begin{aligned}&s=u t+\frac{1}{2} g t^{2} \\&u=0, s=h \\&t=\sqrt{\frac{2 h}{g}}\end{aligned}

Therefore, the time is independent of mass. Thus the time taken by both the balls, will be about the same.
