In order to make the athletic shoe to slide faster of a given surface you had to reduce the friction coefficient of the shoe with the surface.
One way to do that is to put some grease of the sole of the shoe, which undoubtedly would reduce the friction coefficient drastically and the shoe would slide more easily.
Also, if you make the sole smoother the shoe the friction coefficient would decrease and, again, the show would slide mor easily.
When the switch is open then no current can flow, on the other hand, when it is closed, current will pass through. When only “bulb a” is connected to the battery then more current is flowing to “bulb a” causing it to be bright. So the light of “bulb a” will be dimmer.

Answer:
The value of acceleration of the balloon a = 2.9 
Explanation:
Diameter = 8 m
Mass = 400 kg
Speed V = 50
= 13.89 
Coefficient of drag 
= 0.2 for air
Area = 
= 50.24 
We know that force on the balloon is given by
Put all the values in above equation we get
× 0.2
F = 1163.15 N
Now acceleration of the balloon is given by
a = 2.9
This is the value of acceleration of the balloon.
