You are to create a design for a Welder to run efficiently at 20amps. It runs off of 220volts. What type of breaker would you need if you wanted to
work above 35 amps? How many watts is your welder pushing at 20 amps
and at 35 amps? you will need many 9v
batteries and resistance etc. please write answer in a schematic drawing

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

Abeam of electrons with of wavelength of 7.5 x 10-6 m is incident on a pair of narrow rectangular slits separated by 0.75 mm. the resulting interference pattern is projected onto a screen 10.0 m from the slits. what is the separation of the interference maxima in the resulting interference pattern?

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.
