Vectors and forces- tension of cables
The Christmas Star with a mass of 32 kg is suspended between two buildings ready for the Christmas parade of 2019. The buildings are slightly different heights and the cable on the shorter building is at an angle of 63° to the building wall, and the cable attached to the slightly higher building is at an angle of 57° to the building wall.
a) What is the tension in the cable connecting to the shorter building?
b) What is the tension in the cable connecting to the taller building?

What could we achieve, with all the harnessable energy on Earth?
"I know that's a broad question, not to mention involves a lot of speculating; but for example, if we were to gather up and store all the attainable energy, through all the means we have at our disposal, and convert it into one type of energy and fire it all at once, could we achieve time travel? Maybe my question is a little science fictional, but I was just wondering.
I don't know a lot about storing energy or even using it, other than plugging something in (it's on my to do list though), so I don't know a lot of the terms I could use here to paint a better picture. And again, this is a very broad question because I'm not even sure if we know precisely how much energy there actually is on the planet, not to mention solar energy. I mean, without completely breaking down everything including life and converting that into energy. Just pretty much everything we currently can generate or create, without destroying the planet :) What are your thoughts on this?"
