Please look at these videos first before you comment. I want
100% HONEST, truthful, genuine answers, not propaganda
or deceptions or lies that you have been told.

Remember that the melting point of steel is 1532 C. Virtually
all steel foundries need to use special equipment like a blast
furnace, induction furnace or arc furnace to create molten iron
(liquid steel), and these processes require a HUGE amount
of energy.

PLEASE BE SINCERE AND HONEST IN YOUR ANSWERS

I'll be in Destin for the Labor day weekend and was just wondering how the weather has been. The weather forecast says that it'll be thunderstorming all weekend, but I know that sometimes the storms just come either in the early morning or late at night and not during the day. At least in Georgia this past week anyway. I know the weather's always unpredictable, but I'd just like an idea of how it's gonna be like so that I can be more prepared. Thank you!

I'm probably gonna do this ruetnely, (a good chance for me to vote you for best answers).

pls do give full work responses, so that I may learn.

1) Convert 1.90 km/h to m/s.

2) (a) How many square centimeters are there in 2 square feet? (1 in = 2.54 cm.)

(b) How many square centimeters are there in 2 square meters?

(c) Using your answers to parts (a) and (b), roughly how many square feet are in 2 square meters?

3) The smallest "living" thing is probably a type of infectious agent know as a viroid. Viroids are plant pathogens that consist of a circular loop of single-stranded RNA, containing about 300 bases. (Think of the bases as beads strung on a circular RNA string.) The distance from one base to the next (measured along the circumference of the circular loop) is about 0.40 nm.

(a) What is the diameter of a viroid in m?

(b) What is the diameter of a viroid in µm?

(c) What is the diameter of a viroid in in.?

Your teachings are greately appreciated:)
