The four girls settled down in the Physics class. They all sat in a row, one behind another. Rebecca sat in front. Behind her sat Tia then Ian and then Ash.
Mr.Adrian, apperead from the door, and at once got busy in giving lectures.
"Please be with me. Physics course is always alot to cover so I will be going fast. I request you all, do not hesitate in asking questions. Is that clear ?" He demanded
The whole class answered in a chorus. Giving a stiff nod, Mr. Adrian turned towards the board and continued.
"How do we, unlock this app ?" Ash asked tapping Ian on her shoulder.
Ian turned around to face her.
"Try the back button." She whispered.
"Back button ? There is no backing thing. Just only one middle placed and nothing else." Ash hissed.
"Then pressed that. We will see after the class." Ian said.
Ash leaned back, tucking her phone in her pocket whispering some angry words.
"Ok class. Copy the question........,If a ball is travelling in a circle of diameter 10m with velocity 20m/s, find the angular velocity of the ball ?" Mr.Adrian announced
"I hate numericals," Ian murmured.
Tia gave her thumbs up.
"So do I. Don't worry. I am with you." She said making Ian smile.
Rebecca took no notice except her fingers running on the calculator and one hand grazing down her lecture copy.
And within a minute, her hand was shot in the air.
"Yes Miss Immanuel ?"
"Sir, the answer is 4" Rebecca suggested confidently.
"And how did you find this ? Explain."
Rebecca took a deep breath then I continue
"Sir, using the equation, ω=vr .
In this case the radius is 5 which is half of the diameter and linear velocity is 20 m/s. We can divide 20 by 5 and the answer is 4." She said.
"Weldone. Excellent job, Miss Immanuel !" The teacher exclaimed gleefully.
Rebecca grinned and a happy large balloon swelling inside her.
"Next question class !" He barked marching in the middle of the rows with a book in his hands.
"Suppose a car tire rotates 8 times a second. The tire has a diameter of 8 inches. Find the angular velocity in radians per second. ?" He said.
There was again the rush of students running through thier copies and calculators. Mr. Adrian waited patiently for them to finished.
Within two minutes, Rebecca shot up this time another girl raised her arm who was sitting in the corner.
"Yes, Miss...? "
"Kate DeMelo." The girl said.
"Your answer ?"
"16π sir."
Mr. Adrian ceaded his forehead.
"16. Can you explain ?"
"Sir," Kate gulped, going through her copy. " We are taking pie for calculating anguler speed velocity."
"But how did you find out the answer 16. It is correct but any explanation ?"
