Since momentum is a vector quantity, take any direction as positive and other as negative. Answer won't change.
Answer:
Time period, 
Explanation:
Given that,
The quartz crystal used in an electric watch vibrates with a frequency of 32,768 Hz, f = 32768 Hz
We need to find the period of the crystal's motion. The relationship between the frequency and the time period is given by :

T is the time period of the crystal's motion.
Time period is given by :

So, the time period of the crystal's motion is
. Hence, this is the required solution.
Answer:
a battery, wires, and a switch.
Explanation:
All circuits include?
B- Same force
It’s b because force always acts in equal but opposite pairs.
