Maths and Physics Quiz

Please complete the following questions to the best of your ability (use your Maths GCSE notes if you are having difficulties !)

1. Express the following quantities in Standard Form:
e.g. The speed of light in free space is 300,000,000 m/s or 3x10⁸ m/s in standard form.

• 23,000 Kg
• 876,000,000 m
• 0.000123 F
• 1/1000 C
• 20⁵ Km
  

2. Light travels at 3x10⁸ m/s. How far will it have travelled in 16x10¹⁵ s ?

3. The reading on a scale is 35.346 Kg. The scale is only accurate to 3 Significant Figures. Write the reading to the correct degree of accuracy.

4. A bottle contains 500 cm³ of a liquid. Write this volume in m³.

5. If k=100 N/m and m=4 Kg then calculate frequency, f

using the equation

6. An experiment on a metal-filament lamp gave the following values of resistance R (ohms) at various voltages V (volts):

Plot a graph of R (y-axis) against V (x-axis).

Draw a line of best-fit and calculate

• the gradient of the graph
• the intercept on the y-axis.

7. John’s car travels a distance of 750 m in a straight line up a hill. The angle of inclination of the hill is 14 degrees to the horizontal AC. Calculate the vertical height BC.

8. Rearrange the formula v²=u² + 2as so that a is the subject.
