Answer:
6.15 s
Explanation:
The period of a simple pendulum is given by the equation

where
L is the length of the pendulum
g is the acceleration of gravity
For the pendulum in this problem,
L = 1.5 m (length)
(acceleration due to gravity on Earth)
Therefore, its period is

And therefore, the time taken for the pendulum to complete 2.5 oscillations is equal to 2.5 times the period:

You make them strong for example if you rub a balloon in your hair the longer you do it the longer it sticks because of static
For one thing, an object that is not moving has no momentum, no matter how much mass it has. Fast objects are also difficult to stop. Bullets have a very small mass, but you wouldn't want to try and stop one! More speed means more momentum - momentum is directly proportional to velocity
The correct answer is a I hope that helped enjoy the rest of your weekend
