Newtons (N) measure force
The bob passes the lowest point <em><u>twice</u></em> during every complete swing.
The period of this pendulum is <em>0.2 seconds</em>.
Frequency = 1/period
Frequency = 1/0.2 sec
<em>Frequency = 5 Hz.</em> (A very very very short, fast pendulum.)
Note:
The mass of the bob, the angle from the vertical (as long as it's small), the color of the string, and the day of the week have no effect on the period. Only the length of the string has.
Solution :
Given data is :
Density of the milk in the tank, 
Length of the tank, x = 9 m
Height of the tank, z = 3 m
Acceleration of the tank, 
Therefore, the pressure difference between the two points is given by :

Since the tank is completely filled with milk, the vertical acceleration is 

Therefore substituting, we get




Therefore the maximum pressure difference in the tank is Δp = 47.87 kPa and is located at the bottom of the tank.
Answer:
this kind of force is proportional directly to the speed of the object and inversely to the radius of the curved path. Therefore, Hence, the force becomes 2.25 times the original force.
Explanation:
Look on a periodic table and it will be the one that is in the middle that is in big letters like carbon is C and gold is AU
