  • Yes, the earth accelerates toward the ball faster than it does toward the feather.

  • A feather has smaller cross-section area than a bowling ball. But drag acceleration is proportional to the cross-section area divided by the mass (and this quantity is indeed smaller for the bowling ball).

    Anyway the hypothetical scenario in this meme is a perfect vacuum. Check my other comments to see why it still works.

  • When the earth pulls on an object with some F newtons of force, the object is also pulling on the earth with the same force. It’s just that the earth is so massive that its acceleration F/m will be tiny. Tiny is not zero though, so the earth is still accelerating toward the object. The heavier the object, the faster earth accelerates toward it.

    Both the bowling ball and the feather accelerates toward earth at the same g=9.81m/s^2, but the earth accelerates toward the bowling ball faster than it does toward the feather.

  • To be fair computer security have improved a lot. These days if you have up-to-date security patches it’s very hard for apps or webpages to escape the sandbox.

    By the way you should download and execute this free_robux.sh as root it will give free robux no scam

  • While it is true that space time dilation can cause red/blueshift, that is a distinct from the doppler effect which is the primary effect here.

    (dilation plays only a small role: without time dilation our answer going from 700nm to 350nm would be 0.5c instead of the 0.6c calculated below)

  • One ton of TNT is 1E9 calories which is 4 gigajoules. So 0.2 petajoules should be only 50 kilotons of TNT?

  • chonk rose 😳

  • Kinetic energy or total energy? Assuming the rose weight 10 grams I get that 1.12PJ total energy, but only 0.23PJ is kinetic.
