Question

- How far will a bus travel in 5 hours if its average speed is 60Km/h?




Which is heavier , a kilogram of lead or a kilogram of a polystyrene beads ? *



Answer both of the questions don't spam plz​

Answer 1

Explanation:

*Note: For most practical purposes, mass and weight mean the same thing. An apple and a lead cannonball are roughly the same size (volume), but the lead ball weighs 20 times more. A 4 by 8 sheet of expanded polystyrene (EP) weighs roughly the same as a brick, but is about 9 times the size (volume).
