Explanation:
It is given that,
Angular frequency, 
Maximum displacement, A = 0.5 m at t = 0 s
We need to find the time at which it reaches its maximum speed. Firstly, we will find the maximum velocity of the object that is exhibiting SHM.


............(1)
Acceleration of the object, 

...............(2)
Using first equation of motion we can calculate the time taken to reach maximum speed.



t = 0.25 s
So, the object will take 0.25 seconds to reach its maximum speed. Hence, this is the required solution.
<em>The main cause of twice-daily tides around the world are;</em>
Gravitational pull of the moon
<u>Tides are the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. </u>
<u>The moons gravity is large enough to actually pull water out of the ocean from space. Just enough to create motion of the tides.</u>
The circumference of a circle is (pi) x (diameter)
The circumference of the cupcake is (pi) x (5 cm)
Halfway around is (1/2) x (pi) x (5 cm) = (2.5 pi cm) = <em>about 7.85 cm</em>
The 'why' appears up above, in the first 2 lines of this solution.
Answer:
I hope 2 amperes of current passes
Answer:
v = 18.84 m/s
Explanation:
Given that,
The length of the string, r = 1.5 m (it will act as radius)
The rubber stopper makes 120 complete circles every minute.
Since, 1 minute = 60 seconds
It means, its frequency is 2 circles every second.
Let we need to find the average speed of the rubber stopper. It can be calculated as follows :

d is distance,
and 1/T = f (frequency)

So, the average speed of the rubber stopper is 18.84 m/s.
