If the mass on an oscillating spring is doubled, the time period, T, will ???

• Increase

• Decrease

• Stay the same

In an atom, an orbital represents

• the most probably location of a proton

• the most probable location of an electron

• the least probably location of a neutron

• photons emitted as electrons move to lower energy levels

Which statement accurately describes particles of an ideal gas, according to the kinetic molecular theory?

• The distance between the gas particles is much greater than the size of the particles

• As the gas particles collide, the total energy of the system increases

• The gas particles have strong intermolecular forces

• The gas particles move in a circular motion

Under which conditions does a gas behave least like an ideal gas?

• high temperature and low pressure

• high temperature and high pressure

• low temperature and low pressure

• low temperature and high pressure

Which of the following statements is true about both the gravitational force and the electrostatic force?

• The force can attract for opposite types of (mass or charge), and repel for like types.

• The force is inverseley related to the square of the distance.

• The force only shows up when objects are in contact, i.e. touching.

• The gravitational force and electrostatic are about equally strong.

Which of these is the best definition of polarization?

• The object gains a positive or negative charge from another object.

• The charges in a neutral object separate due to a nearby charged object.

• Charges on a neutral object jump off onto a charged object due to attraction of opposite charges.

• Two objects attract each other because they are both charged.
