Answer:
There are different ways to investigate density. In this required practical activity, it is important to:
record the mass accurately
measure and observe the mass and the volume of the different objects
use appropriate apparatus and methods to measure volume and mass and use that to investigate density
Explanation:
Answer:

Answer:
Maximum acceleration will be equal to
Explanation:
We have given coefficient of kinetic friction
And coefficient of static friction
Acceleration due to gravity
When truck moves maximum force will be equal to
It is given that half of the weight is supported by its drive wheels
So force required
From newtons law maximum acceleration will be equal to
