Explain the formation of a lateral moraine

The rocky material used to construct a lateral moraine is usually a result of freeze-thaw weathering. Water gets into cracks in rocks on the mountain slopes when the temperature is above zero and subsequentl...

What is a nerve synapse, and how does it transfer information?

Synapses are junctions between nerves. They allow information (impulses) to be transferred from one nerve to the next. The first nerve conducts an electrical impulse across its length, which causes it to rel...

What is Determinism, in the context of freewill?

Determinism is the belief that humans have no freewill to choose to do as they wish, due to the influence of external forces upon us. Such external forces may, for example, be how we have been conditioned by...

Photons with 605 THz frequency strike metal of 1.2eV work function. Calculate the maximum energy of photoelectrons and their velocity. What amount of energy is necessary to stop all photoelectrons? (Planck's constant. electron mass and charge are given)

Start off by converting all given data into SI units to avoid confusion later on. The photoelectric effect happens when photons with energy larger than work function strike metal, thus releasing the electron...

The amplitude of a simple harmonic oscillator has decreased from 40cm to 38cm. What percentage of energy did the harmonic oscillator lose?

It is recommended to start off by converting all given data into SI units to avoid confusion later on. Write down the total energy of the system and that it is conserved: E(tot)= KE+PE and KE=(mv^2)/2; PE=(k...
