How are “ride-able explosions” made just right so that they’ll generate the kind of thrust that sends a rocket up, up, up?
If we know that stars are massive spheres of hot gases, then why do we draw them with lots of twinkly points? Minute Physics: Why are Stars Star-Shaped?
There are 13 dominoes in this sequence. If Professor Morris used 29 dominoes in total, with the next one always being 1.5x larger, the last domino would be the height of the Empire State Building.
When a magnetic field moves through a conductor a current called an Eddy current is induced in the conductor due to the magnetic field’s movement. The flow of electrons in the conductor creates an opposing magnetic field to the magnet which results in damping of the magnet and causes heating inside of the conductor similar to heat buildup inside of power cords. The loss of energy used to heat up the conductor is equal to the loss of kinetic energy by the magnet.
Who better than a talking oscilloscope to explain what frequency is and why it’s so important for radio and sound waves.
