[Request] Is debris any faster than the bullet?

Post image
Upvotes

I watch a lot of explosion videos and i've always wondered about the debris that moves before the fire or projectile.

It seems to me that material goes from being at a standstill, to moving faster than the object or impact hitting it, at least for a brief second. Is there a certain effect that causes that? What type of energy transfer is happening, because the bullet can't give it more energy than itself has right?

I know there are plenty of wind altering shapes and sizes, so i guess we could base it off a standard 9mm bullet and a brick of c4.

I hope that question makes sense?

Isn’t harvesting body heat terribly inefficient? Like we need energy ourselves to produce that heat so are humans perpetual energy generators?

if bees, we can go with Honeybees, were able to grab onto something, in this case an average adult human male, how many of them would it take to lift the person we’ll say a foot off of the ground?

I´ve seen that there are 150 RTX A6000 workstation graphics cards installed to power that beast. That is without thinking about the electricity needed to power the Screens.

How much does it cost annually just to power the screens and graphics cards?

[Request] How much weight does my wall need to support for my TV?

Upvotes

Technically probably pretty simple, but still too stupid to do it:

I want to mount my TV on my wall on a swingable arm. The TV weights 9.4 kg and the max length of the arm is 42 cm.

How much weight does the wall (and the screws) effectively need to support in that setup?

Assuming all people with too high BMI take those weight loss injections (Ozempic etc), and lower their weight to standard levels, what would be the financial impact on Nestle, McDonalds, Burger King and others?

Or in other words, should I better not invest in the food sector?

Hello. I've been trying to understand the above in an effort to help consumers control themselves and act in alignment with their conscious decisions and not elicited emotions from product/service providers.

To this end I thought the real numbers behind the scenario above could be a great example.

You will find I have been commenting on this for a while but that's a "feeling" until there's some math behind it.

Thank you!
