Answer:
Explanation:
As we know that the block of wood is suspended by spring
Now at equilibrium position we have net force balanced on it
so we have
so we will have
now the time period of the spring block system for one complete oscillation is given as
now plug in all values in it
Now total time to complete 3 cycles is given as
Answer:
Option A
Explanation:
Acceleration will be obviously zero when Force = 0
<u><em>That is how</em></u>:
Force = Mass * Acceleration
So, If force = 0
0 = Mass * Acceleration.
Dividing both sides by Mass
Acceleration = 0/Mass
Acceleration = 0 m/s²
The third bulb may take extra current from the 12V battery. and extra power
the answer should be 20 seconds
