Physics

Question 1

How to Calculate Electric Field

Answer 1

Or, Volts/Meter (V/M)

or V/d

Question 2

Frequency?

Answer 2

f=c/lamda

or

frequency= speed of light/ wavelength (in meters)

Question 3

destructive intereference

Answer 3

waves are 180 degrees apart, they cancel each other out

Question 4

Period?

Answer 4

T=1/f

Question 5

voltage?

Answer 5

V=IR

Question 6

Change of U of a system

Answer 6

U= Q-W_{by gas}

Question 7

work?

Answer 7

W=P(deltaV)

Question 8

adiabatic

Answer 8

q=0

U=q-W_by

Question 9

isothermal

Answer 9

U=0

U=q-w_by
