Answer 2

material of the object

Question 3

what is the dependent variable in this practical?

Answer 3

the density of the object

Question 4

what is the control variable in this practical?

Answer 4

the gravitational field strength

Question 5

what is the first step in the method for finding the density of a regular object?

Answer 5

measure the mass of the object using a balance

Question 6

what is the second step in the method for finding the density of a regular object?

Answer 6

measure the length, width and height of the object with a ruler

Question 7

what is the third step in the method for finding the density of a regular object?

Answer 7

calculate its volume ( volume = length x width x height )

Question 8

what is the final step in the method for finding the density of a regular object?

Answer 8

calculate its density ( density = mass divided by volume )

Question 9

what is the first step in the method for finding the density of an IRregular object?

Answer 9

measure the mass of the object using a balance

Question 10

what is the second step in the method for finding the density of an IRregular object?

Answer 10

fill a displacement can up to the spout with water

Question 11
