Magnetic fields don’t do work directly, but they still hold energy, given by $$ u_B = \frac{B^2}{2\mu_0} $$. When the field changes, it can create electric fields that do the work, like what happens in inductors. That’s how the energy gets transferred around.

Hi, so you should know that pi sign is used more in physics than chemistry :oldbiggrin:

Smooth walls and easy bends help air move better through the duct. Tapering it a bit can speed up the airflow to cool the brakes more. Spinning the air sounds cool but it usually just makes things messy... so straight and simple works best.

The second method is pretty common for windlass setups. Even with just two strands through the link, the load spreads out fine if it’s spliced right.

Add this to the end of the script: input("Press Enter to exit...") Or run the script from an open command prompt instead of double clicking: python your_script.py That way, the window stays open and the error messages won’t disappear right away. Another trick...run it like this: python -i...

His Scaring hissing.. :oldfrown:

Modern subs run quiet because of electric drives, most probably with PMS motors. Some could use gearboxes to slow the prop, others go direct.

Isopentane boils around 82°F so it's a good pick for low temp setups. You can change the boiling point a bit with salt or by messing with pressure. Keep safety in mind...it’s flammable!!

Water moves up trees mainly because of transpiration, cohesion, and adhesion in the xylem, not because of the nodes and internodes. Those parts help support the plant but it’s the transpiration pull that gets water to the leaves.

How important early social interaction is...without it, even healthy kids can end with serious, lasting delays.

Please ask from that person how is this incorrect interpretation...

Raise the standpipe and mess with the pipe sizes.

If you put the photon counter at a dark node, it's not likely to pick up any photons because of the destructive interference. But there could be a tiny chance it detects something due to noise or imperfections in the setup. The experiment might still show some weird stuff in those dark areas...

Surface tension is like pulling to make less contact. It pulls up at the bubble liquid interface and down at the air bubble one, and it balances everything out vertically. Basically it’s just trying to shrink the exposed surface area.

Hi eveyone!!. I am new here, and i know (not much) about physics so maybe I could help anyone. And I may post physics questions that I can't solve so you can help me out.
