- In an experiment, a student burns 25 g of a solid fuel. Its mass decreases by 23% Calculate the mass of the solid after the experiment.
- A student recorded the acceleration of a trolley down a ramp. 0.7m/s^2, 0.6m/s^2, 0.8m/s^2, 0.8m/s^2 Calculate the mean acceleration to 1 decimal place.
- Venn diagrams are used for comparing and contrasting topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. This Venn diagram is comparing mechanical and electromagnetic waves. What could be put into the center section of this Venn diagram? "Carry energy through space" and "Follow a pattern" "Carry energy" and "Follow a pattern" "Carry energy through space" and "Can be heard" "Carry energy" and "Can be heard"
- The mass of an organism increases from 50 g to 95 g. Calculate the percentage change in mass. Use the equation: percentage change=(final value - original value)/(original value)times 100
