It depends on the person.if you like the song then it loses your focus because you might start singing and that's how it affects your concentration.
What are the two sets? I only see the two answers?
As the climber climbs the mountain, he needs to over his or her own weight component along the slope of the mountains.
By Newton's second law: Net force = Mass x acceleration
Hence, greater the mass, greater will be the force required to move up the mountain. Hence, the climber will need to apply higher force to climb up as he or she has packed too much, which resulted in the increase in the mass. Hence, there is a increase in the force which will pull him or her downward.
It will decrease the capacitance because we know nothing about the charge.
