1- A simple pendulum oscillates with a period of 2.05s. What is the length of this pendulum in units of meters? Note: In the space below, please enter you numerical answer. Do not enter any units. If you enter units, your answer will be marked as incorrect.

3-A small choir is preparing to sing. If we approximate that each person sings with sound intensity level of 45 dB at a distance of 10 meters, and we start with a single singer, what will the new sound intensity level be if 7 more people join in (in decibels)? Note: In the space below, please enter you numerical answer. Do not enter any units. If you enter units, your answer will be marked as incorrect

5-Suppose you have 0.32 moles of an ideal gas. What is the average kinetic energy of that gas (in units of kJ) if the temperature of the gas is 296.9K? Note: It is understood that the unit of your answer is some number of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.

6-Two charges, q₁=-3.91mC and q₂=--1.96mC are placed 8.11m apart from one another (mC stand for "milli-Coulomb"). What is the the electric force that q₂experiences due to the presence of q₁? Note, if the force direction is "to the left" be sure to include a negative sign. If the direction of the force is "to the right", the force should be positive in sign.

Note: It is understood that the unit of your answer is in Newtons, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

7-If the battery in the circuit below is 3.53V, resistor R₁=69.44, and resistor R₂=61.16, what is the magnitude of the potential drop across resistor R₂? Please give your answer in units of Volts (V).

Note: It is understood that the unit of your answer is in Volts (V), however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

8-A 11.38m wire carries a current of 96.39mA perpendicular to a uniform magnetic field of magnitude 1.22T. What is the magnitude of the force the wire experiences due to the presence of the magnetic field?

Note: It is understood that the unit of your answer is in Newtons, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong

9-Suppose a 5.8mC charge moves with velocity 571.95 m/s at an angle of 26.18relative to the direction of a uniform magnetic field of magnitude 2.43T exists. What is the magnitude of the magnetic force this charge experiences?

Note: It is understood that the unit of your answer is in Newtons, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.
