A joule is one Newton of force applied over a meter.
For every meter, the brakes put 240000N of force (N=Newtons).
For 40m, multiply the Newtons by 40.
240000N*40=9600000N
The air that was inside the balloon will expand to fill the room
Explanation:
Matter exists in three states:
- Solid: in a solid, the molecules are bound to each other by strong intermolecular bonds, so they are not able to move freely, but only to vibrate around their fixed position. As a result, solids have a definite shape and a definite volume.
- Liquid: in a liquid, the molecules are free to slide past each other, however there are still intermolecular forces acting between them that prevent them to move too far apart from each other. As a result, liquids have a definite volume, but not a definite shape.
- Gas: in a gas, intermolecular forces between molecules are negligible, and molecules can move freely. As a result, gases have no definite volume and no definite shape.
According to the definition of gas, this means that in this problem, when the air is released from the balloon, the molecules of air will move out of it and will try to fill the whole space available, which is the room.

Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
