Biography

I am a student turned educator! After completing two degrees, B. Sc. in Math and Physics and M. Sc. in Physics and Astronomy, I have pursued anything and everything teaching. I currently work for a charity organization called Scientists in School - an organization that provides half day science workshops to elementary aged children. I also work for an online teaching company called VIPKID teaching English as a Second Language to young Chinese learners. I also work for a company called the Princeton Review. I teach first year level physics for students studying for the MCAT.

University Physics with Modern Physics

(a) Calculate the magnitude of the angular momentum of the earth in a circular orbit around the sun. Is it reasonable to model it as a particle? (b) Calculate the magnitude of the angular momentum of the earth due to its rotation around an axis through the north and south poles, modeling it as a uniform sphere. Consult Appendix E and the astronomical data in Appendix F.

University Physics with Modern Physics

A hot-air balloon stays aloft because hot air at atmospheric pressure is less dense than cooler air at the same pressure. If the volume of the balloon is 500.0 m$^3$ and the surrounding air is at 15.0$^\circ$C, what must the temperature of the air in the balloon be for it to lift a total load of 290 kg (in addition to the mass of the hot air)? The density of air at 15.0$^\circ$C and atmospheric pressure is 1.23 kg/m$^3$.

A cylinder 1.00 m tall with inside diameter 0.120 m is used to hold propane gas (molar mass 44.1 g/mol) for use in a barbecue. It is initially filled with gas until the gauge pressure is 1.30 $\times$ 10$^6$ Pa at 22.0$^\circ$C. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure is 3.40 $\times$ 10$^5$ Pa. Calculate the mass of propane that has been used.

(II) In Fig. 35 the coefficient of static friction between mass
$m_{\mathrm{A}}$ and the table is $0.40,$ whereas the coefficient of kinetic
friction is 0.30$(a)$ What
minimum value of $m_{A}$
will keep the system
from starting to move?
(b) What value(s) of $m_{A}$
will keep the system
moving at constant
speed?

(II) An object moving vertically has $\vec{\mathbf{v}}=\vec{\mathbf{v}}_{0}$ at $t=0$ .
Determine a formula for its velocity as a function of time
assuming a resistive force $F=-b v$ as well as gravity for
two cases: $(a) \vec{\mathbf{v}}_{0}$ is downward and $(b) \vec{\mathbf{v}}_{0}$ is upward.
