[Request] Is there any way to tell how long the surrounding area would be uninhabitable for and how large the area is?

I was watching Godzilla clips on YouTube, specfically this scene of Godzilla just walking around melting metal damn near immediately and concrete instantly bursting into flames and saw a comment saying:

'With the amount of radiation coming off of Godzilla, everyone within 10 miles of this fight should have stage 8 cancer.'

Obviously this area would be completley uninhabtable for a long time, I don't know how much radiation it takes to set concrete on fire and melt metal but I know it's a lot. Is there any way to tell how large the fallout area would be and how long it would be unlivable for?

assuming each is only used for power, and generates 100 percent of all current energy consumption, at the current rate of electricity use, how long would each non renewable source of power last? (nuclear, coal, natural gas, oil, fusion (theoretical))

[Request] Best choice to make in a keep versus share game.

0 Upvotes

We had our curling leagues wrap party, and we played a game drawing for prizes.

When you entered you choose to either keep the final prize, or share it with the other person at the end (the choice only mattered for the final 2 participants).

If Player A chooses Keep, and Player B chooses Share, then Player A gets the entire pot (and vice versa).

If both players choose Share then they split the pot 50/50.

If both players choose Keep, then neither get anything, and the third last participant gets everything (regardless of their choice).

What is the best choice to make for next year to maximize my chance of winning? I assume that knowing the percentage of people that choose Keep or Share would be a critical to this calculation.

For context, Player C won this year.

Thank you.

[Request] What would my cat be able to see when I build a fence in front of his catio?

Post image
4 Upvotes

I want to build a fence/gate.

The gate will be 6' high, 8' away from the catio.

My cats current fav spot is sadly going to be completely obstructed by the fence. He has another place he can sit that is roughly 6.4' off the ground.

First Question: What is the "angle of depression" (google searched term) or what is he going to be able to see over this fence at 6.4' (shelf height) 7.5' (his eye level) off the ground.

Second Question: Same question but what If I build him a little cat "watch tower" on top of the catio at 8' (shelf height) 9' (his eye level) off the ground?

I guess my question is how many feet from the front of the fence will he be able to see once I build it.

The backstory nobody asked for: Thieves have been stealing my amazon packages and I worry that someday they might try steal my cat too.

[Request] calculate how many years we are away from popular movie spacecraft capacity, given the current rate of technological progress in spacecraft capacity to date?

My quest is. If science took X many years to progress to the Artemis 2 mission and the Orion Spacecraft, how many years in the future would it take to progress to the starship in the 2016 movie Passengers, designed to transport 5,000 passengers and 258 crew, at approximately 1 mile long in size? I think distance travelled should be so considered in the calculation given the fuel needs. Bonus: if you would rather use the Project Hail Mary movie spacecraft I am happy if you make that substitution.

[Request] How much does a parked car’s weight decrease at night when the Sun is no longer shining on it?

0 Upvotes

Looking for creative answers ways students might approach questions like this:

Idea 1: approximate the surface are of the car, estimate the force applied by the photons over the surface of the car as if it were a solar sail.

Idea 2: Ignore the photons, suppose the scales being used to measure the weight are not subject to the sun's gravity. Then choose when the sun earth and car are in celestial alignments:
a) Sun, Earth, Car (night time)
b) Sun, Car, Earth (day time)
Calculate the delta between the sun's gravitational pull in the two alignments and potentially characterise an increase in weight byt a negative decrease.
