Ionic compounds form crystal structures. molecular structures. pure elements. neutral elements
Naddik [55]

Answer: Option (a) is the correct answer.

Explanation:

Ionic compounds are the compounds whose atoms are combined together by transfer of electrons.

An ionic compound has partial positive charge on the cation and partial negative charge on anion.

For example, NaCl is an ionic compound whose atoms are arranged orderly due to the opposite charges on its atoms.

So, an ionic compound forms a neutral compound but not a neutral element.

Thus, we can conclude that ionic compounds form crystal structures.

How is newtons third law of motion demonstrated on a roller coaster?
butalik [34]
<span>Newton's Third Law of Action-Reaction is that for each and every action that happens, there is an equal and opposite reaction to it. In the scenario of a roller coaster, this is when you push down on the seat of the roller coaster as it flies along and the seat pushes back against you.</span>

A 91.5 kg football player running east at 2.73 m/s tackles a 63.5 kg player running east at 3.09 m/s. what is their velocity aft
vivado [14]

Their velocity afterwards is 2.88 m/s east

Explanation:

We can solve this problem by using the law of conservation of momentum. In fact, for an isolated system (= no external force), the total momentum must be conserved before and after the collision. So we can write:

p_i = p_f\\m_1 u_1 + m_2 u_2 = (m_1 + m_2)v

where: in this case:

m_1 = 91.5 kg is the mass of the first player

u_1 = 2.73 m/s is the initial velocity of the first player (choosing east as positive direction)

m_2 = 63.5 kg is the mass of the second player

u_2 = 3.09 m/s is the initial velocity of the second player

v is their combined velocity afterwards

Solving for v, we find:

v = \frac{m_1 u_1+m_2 u_2}{m_1+m_2}=\frac{(91.5)(2.73)+(63.5)(3.09)}{91.5+63.5}=2.88 m/s

And the sign is positive, so the direction is east.
