1.Use the balance to find the mass of the object. Record the value on the "Density Data Chart."
2.Pour water into a graduated cylinder up to an easily-read value, such as 50 milliliters and record the number.
3.Drop the object into the cylinder and record the new value in millimeters.
4.The difference between the two numbers is the object's volume. Remember that 1 milliliter is equal to 1 cubic centimeter. Record the volume on the data chart.
5.Compute the density of the object by dividing the mass value by the volume value. Record the density on the data chart.
Answer:
The tension in the rope is 262.88 N
Explanation:
Given:
Weight 
N
Length of rope 
m
Initial speed of ball 
For finding the tension in the rope,
First find the mass of rod,
( 
)
kg
Tension in the rope is,
N
Therefore, the tension in the rope is 262.88 N
3.75kmper squ hr
acc = (v - u) /t
=(54-32)/8
=22/8
= 3.75kmhr^-2
