Presentation transcript:

Go Back > A cube has length 2cm. Its mass is 4g. What is its density? Question 1 = 0.5g/cm 3 ?

= 13.33m/s Question 2 Go Back > Paul the Bobcat runs from one tree to another (100m away) at a speed of 20m/s, and then 10m/s coming back. What was his average speed? ?

Question 3 Go Back > A fish tank leaks water at a rate of 500 litres per hour. How many litres per second is this? Rate = l/s ? 1 gallon = 3.79 litres

Question 4 Go Back > Mass = 14.61kg ? A uranium rod in a cylindrical shape has diameter 10cm and length 30cm. Its density is 6.2g/cm 3. What is its mass? (in kg, to 2dp)

Question 5 Go Back > Depth = 55cm A swimming pool is 20m x 30m. Given that that the density of water is 1000kg/m 3 and it is filled with 330,000kg of water, what is the depth of water? ?

Question 6 Go Back > NO QUESTION HERE YET! TURN BACK! Honestly, do this now! Quick!
