The answer is d! I’m happy to help :)
Answer:
The First is an example of acceleration, the second is an example of velocity
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.
The car's rate of acceleration : a = 2.04 m/s²
<h3>Further explanation</h3>
Given
speed = 110 km/hr
time = 15 s
Required
The acceleration
Solution
110 km/hr⇒30.56 m/s
Acceleration is the change in velocity over time
a = Δv : Δt
Input the value :
a = 30.56 m/s : 15 s
a = 2.04 m/s²
Answer:
Here ball and rod will repel each other as they are of similar charges
Explanation:
As we know that the two charges attract or repel each other by electrostatic force
This force is given as
so we know if two charges are similar in nature then they will repel each other and if the two charges are opposite in nature then they will attract each other
So here when rod touch the ball then it transfer its charge to the ball and due to similar charges in ball and rod they both repel each other
