Answer: 1) Mass is a scalar quantity while weight is a vector quantity
2) Mass is measured in Gramma and kilogram while weight is measured in Newton.
Explanation:
Mass can be defined as the amount of matter that comprises an object. It is a scalar quantity, that is, it has magnitude. It is measured in kilogram with its unit in Kg. Mass is measured using an ordinary weighing scale.
Weight can be defined as the force acted upon an object due to gravity. Weight is a vector quantity, that is, it has both magnitude and direction towards the center of the earth. Weight can be measured with the use of a spring balance. Its unit is in Newton.

Answer:
0.32 s
Explanation:
Initial angular speed: 
Final angular speed: 
Angular rotation: 
The angular acceleration of the drill can be found by using the equation:
Re-arranging it, we find 
, the angular acceleration:
Now we want to know the time t the drill takes to accelerate from
to
This can be found by using the equation
where is the angular acceleration we found previously. Solving for t,
