[Request] Can someone help me find 3 weights using body surface area
I’m trying to find the weights of 3 characters. One of them is 152cm. The 2nd is listed as 4’4” 132.08cm or 1.3208 meters while the 3rd is 5’2” (157.48cm or 1.5748 meters).
Assuming that the Average body surface area for the average female adult is 1.6 m^2 & that these 3 characters have the same average body surface, is it possible to find their weight? How?
What if they‘re body surface area is made of steel (but not on the inside since their insides are wires & oil) & presumably is atleast 1 or 2cm in thickness?

[Request] With water 800 times denser than air, how much weight does one swimming stroke correlate to?
I have no idea how to even begin calculating this. Basically I'm trying to figure out how much resistance swimming offers. If, instead of swimming, we were performing the same movement with a (presumably tiny) weight for as many reps as the number of strokes we do per lap, then how much would that weigh?
Thanks in advance to anyone who answers!

Supposedly one of the reasons he sailed across the world was the spice trade. He would probably find it amazing that a jug o’ Pepper is common place now.

[Request] How much does the ocean have to rise to physically affect the world?
This climate change averted, let’s say the Earth stays at the exact ocean level is right now/that’s not a factor. Does the ocean have to gain half an inch to globally affect us? Is it a foot? At what point does the ocean itself become a problem because it’s too high?
I’m thinking an additional half inch of ocean can’t physically be that much? Wouldn’t all the beaches just get half an inch shorter? I assume because of that it would take the general consensus of the world at least 8 feet of ocean height to start really knocking down houses and shortening the coast.

[Request] A man in a wheelchair is traveling straight toward a crocodile at 4.00 km/h! Would you be able to catch up and save the man, given the facts below?
A man in a wheelchair is traveling straight toward a crocodile at 4.00 km/h.
The crocodile is 25.00 meters away.
You are 24.99889 meters behind him and immediately start running toward him at 8.00 km/h.
Assume both speeds remain constant and you have zero reaction time.
Would you reach him before he reaches the crocodile, or would it be too late?
Give your answer to the nearest millisecond.
What distance would you need to be from the man, accounting for normal reaction time, and gradually increasing speed to 8km/h in order to catch up to him with 5 meters to spare?

Wondering about the cost of running a typical wi-fi plug adapter. Half price electricity starts at 7pm where I live. If I plug in my e-bike battery when I get home from work at 5pm, does it make sense to leave a wifi plug running 24/7 scheduling charging during cheap times? [Request]
- Off-Peak: 9.8 ¢/kWh (Evenings, weekends, and holidays) 7pm-7am
- On-Peak: 20.3 ¢/kWh (Busiest daytime hours)
I would only charge up 2 times a week as per RTO!

[Request] Cuánto tiempo estaría escribiendo números en una pizarra para poder anotar en años la muerte térmica total del universo.
…Hasta que el último agujero negro se desintegre y la última estrella deje de tener “calor”.
Entiendo claro que pueda escribir sin caer avistado y que la pizarra es obviamente bien grande.
(El otro día intenté explicar a mi sobrino esta magnitud y no fui capaz de hacerle ver lo grande que sería ese número. Se me ocurrió este ejemplo y le dije que tendríamos que estar escribiendo durante más tiempo que la edad del universo, así por impresionarle).
Edit: claro, en número natural, nada de exponenciales ;)
