Answer:
30m/s²
Explanation:
The acceleration of the motorcycle in section CD is the slope of the velocity - time graph.
Given that;
Initial velocity = 20m/s Time = 6s
Final velocity = 50m/s Time = 7s
The time interval = 7s - 6s = 1s
So;
Acceleration = 
= 
= 30m/s²
The answer is B tell me if I am wrong.
Answer:
Average velocity = 1.835 m/s
Explanation:
Detailed explanation and calculation is shown in the image below
When an atom becomes electrically charged the number of electrons or protons stops and they are not equal again. The "extra" electron or proton is not balanced by something inside the atom any longer and it starts attracting itself to othet protons or electrons in other atoms.
<h3>What is atomic structure?</h3>
An atomic structure comprises of positively charged nucleus which is surrounded by negatively charged particles called electron and neutron which is neutral charged.
Unlike charges attract each other while like charges repel each other.
Therefore, When an electron is fully charged, the number of electrons will stop to be unequal again.
