The candle flame releases hot gases, which directly go in upwards directions. Due to which the air near the flame of the candle is very hot and dense. The particles along with vapour move up. And since the sideways, the air is not very dense and hot, we are able to hold the candle. In anti-gravity region, there will be no density differences and also, the convection process wont occur. So, the candle quickly snuffs off.

A! Good luck on your test!
Answer:
a) v = 0
b) The aceleration is 1.41 
c) The block is accelerating away from the wall.
Explanation:
First, you need to think about the effect this constant force is causing in the spring: it causes a displacement in the equilibrium point of the system, therefore we need to know where it sits now:
At equilibrium no movement is present reducing friction to 0:




This means that the spring can be compressed with the single force up to 68 cm, Any further compression will cause an unbalanced system and the occilation of the mass.
The spring can't be compressed by the given force to 80 cm, therefore it must have been compressed by another force and then released.
In this case, the instantanous speed is 0, since the block has just been released.
In the same instant we can stimate the free body diagram of forces by the next two equations:

For the y axis:

To calculate the force of friction:

Therefore for x axis:
