A balloon filled with helium gas has an average density of
1 answer:
Average density is defined by following formula
here in order to find out the average density of helium we can fill a balloon of helium gas and then we can find it's volume and its mass.
The ratio of mass and volume of that balloon will help us to find the average density of helium
So by the above experiment the average density of helium is approx 0.179 kg/m^3.

The work done on the Puck by the applied force from the most positive to the most negative is c, b, a respectively.
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
The force applied to an object increases with increases in the velocity of the object.
In the given diagram, the resultant velocity of the puck is calculated as follows;
Figure a:
Figure b:
Figure c:
