22) Draw a diagram. This is similar to an example we did in class. a) Label the 3 forces acting on the mass.
b) Write down the (x, y) components of the electric force, Fe.
c) Write down the equations for F(x, y) = 0.
d) Solve the y equation for the magnitude of E (remember to
change gm - kg). First, solve for Ey then find E.
Ilsina x equation, solve for the tension T in the string.

c)as speed changes, wavelength and frequency change.

everything changes!

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

no simpler subs form complex ones. synthesise = make

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
