Answer:
Option B:
A child sitting on a swing.
Explanation:
When we hear the word oscillator, a good example is the pendulum bob of a grandfather clock. We can picture the motion to get a perfect understanding of its path of motion and relate it to other systems of motion in our everyday life.
An oscillator is a system that moves in such a way that it reverses its direction after a period of time. It can be seen as a "to-and-fro" motion.
From the options, a child sitting on a swing is the perfect example of an oscillating system because the child will be moving forwards and backwards, alternately reversing the direction of motion with time.
Answer:
Explanation:
conversion of 2.5 days to seconds
2.5 days =2.5 days*24 hours*3600 seconds
2.5 days=216000seconds
b) conversion of 25 km to mm
1 km=1000000 mm
therefore
25 km=25*1000000=25000000 mm
c) conversion 22 g to kg
1000 g=1 kg
therefore
22 g=22/1000=0.022 kg
