Read the information below for Question no. 6 & 7.

Nimra has made some sherbet. She followed this recipe: Sherbet Recipe

She found that citric acid reacted with sodium bicarbonate when it was mixed with water. This reaction produced carbon dioxide in the form of bubbles. She decided to try different amounts of ingredients to see what would happen. Here are the mixtures she tried and the time each mixture bubbled.

In order to have a fair test, the amount of only one ingredient should be changed in each experiment. Between experiment

1 and experiment 2, the amount of which ingredient was changed?

What did Nimra find about the mixtures? The mixture makes more carbon dioxide when

A) there is more citric acid than sodium bicarbonate.

B) there is less icing sugar than sodium bicarbonate.

C) the amount of citric acid and icing sugar is the same.

D) the amount of sodium bicarbonate and citric acid is the same.

Rashid and Khalid threw one ball each. The boys are the same height and both threw the ball at the same angle. Rashid

threw the ball harder than Khalid. Which of the following correctly describes what happened to the two balls?

A lever is a simple machine. A lever consists of a bar which is supported by a fulcrum (F) upon which it turns. An effort

force (E) is applied to the bar to move the resistance force or load (L). There are three classes of lever. They are determined

by the positions of the fulcrum, effort force and load as shown in the diagram. The arrows show the direction of the forces.

The photograph shows a shovel being used to lift a load. At which position along the shovel is the fulcrum located during

this task?
