A string (with uniform mass density) is attached to a wave generator with variable frequency to create standing wave patterns. The string goes over a pulley and is connected to a mass (which can be varied) to create tension in the string.1) If the frequency is changed (while the mass is held fixed), what else will change? a) The wavelength of the wave will change.
b) The speed of propogation of the wave will change.
c) Both the wavelength and speed of propogation of the wave will change.
d) Neither the wavelength nor speed of propogation of the wave will change.
2) If the hanging mass is changed (while the frequency is held fixed), what else will change?
a) The wavelength of the wave will change.
b) The speed of propogation of the wave will change.
c) Both the wavelength and speed of propogation of the wave will change.
d) Neither the wavelength nor speed of propogation of the wave will change.

Which notation is used to represent an alpha particle? a. b. c. d.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
