Answer:
c)The gases have the same average kinetic energy.
Explanation:
As we know that the kinetic energy of gas is given as
here we know that
so we have
now we have
now mean kinetic energy per molecule is given as
so this is independent of the mass of the gas
so average kinetic energy will remain same for both the gas molecules
Answer:
The direction will be and the distance 250.75km.
Explanation:
Let's say A is the displacement vector which represents the first 170km and B the one for the next 230km. Then the components of these vector will be:
The vector which point from the origin to the final position of the plane will be R=A+B. We sum components on <em>x </em>and <em>y </em>independetly (vector property):
If is the direction of R then:
⇒
⇒
.
The distance will be given by the magnitud of the vector R:
⇒
.
