1) In first case, both the objects(hand & tea) are in direct contact, so heat will flow by the process of "Conduction"
2) In this case, objects are not in direct contact, and heat is transferring from one to another by "Convection"
3) Here, there is no contact between the objects (our body & sun), sun light with heat comes through the process of "Radiation"
In short, Your Answers would be:
1) Conduction
2) Convection
3) Radiation
Hope this helps!
Answer:
I don't know if it's fair for me to write an entire essay for you
but if you would like I can list some reasons you can incorporate into an essay.

-If you are joining a gang you are most likely going to have a greater chance of being targeted, even if it seems like you would be protected.
-Most of the time when someone joins a gang a child is being separated from a parent and will face most aggression.
-This can also cause academic failure in students, from lack of education and probably a pretty bad background.
-For teens when joining a gang they will do things that aren't suited for their age (I would list things but I'm not trying to get myself reported if you know what I mean)
-You will also have a great risk of being imprisoned and facing bad consequences, and these consequences can even be having the death penalty.

I hope this is good enough, sorry I didn't give you a full essay. I think this should help with that though.
Answer:
Work done, W = 5534.53 J
Explanation:
It is given that,
Force acting on the piano, F = 6157 N
It is pushed up a distance of 2.41 m friction less plank.
Let W is the work done in sliding the piano up the plank at a slow constant rate. It is given by :
Since, 
(in vertical direction)
W = 5534.53 J
So, the work done in sliding the piano up the plank is 5534.53 J. Hence, this is the required solution.
