Question

1 cubic metre of concrete has a weight of 2400 kg.
15% of the concrete is water.

The rest of the ingredients of concrete are cement, sand and stone.
The weights of these ingredients are in the ratio 1 : 2 : 5
Work out the weight of cement, sand and stone in 1 cubic metre of concrete.
sand= ............kg
cement=..........kg
stone=............kg

Answer 1

Step-by-step explanation:

Therefore, the weight of cement in 1 cubic meter of concrete is 255 kg. Therefore, the weight of sand in 1 cubic meter of concrete is 510 kg. Therefore, the weight of stone in 1 cubic meter of concrete is 1275 kg.

Answer 2

Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).
