Biography

I am a PhD level physicist who is actively working on research and engineering projects in rock mechanics. I have continuously and passionately been involved with tutoring since I was a student and teaching in graduate school. I would love to be able to share my experience and knowledge to help make this difficult subject more accessible, enjoyable, and understandable to everyone.

The intensity due to a number of independent sound sources is the sum of the individual intensities. (a) When four quadruplets cry simultaneously, how many decibels greater is the sound intensity level than when a single one cries? (b) To increase the sound intensity level again by the same number of decibels as in part (a), how many more crying babies are required?

Engineering Mechanics: Dynamics

The acceleration of a particle is given by $a=2 t-10$ where $a$ is in meters per second squared and $t$ is in seconds. Determine the velocity and displacement as functions of time. The initial displacement at $t=0$ is $s_{0}=-4 \mathrm{m},$ and the initial velocity is $v_{0}=3 \mathrm{m} / \mathrm{s}$

An important concern in the study of heat transfer is to determine the steady-state temperature distribution of a thin plate when the temperature around the boundary is known. Assume the plate shown in the figure represents a cross section of a metal beam, with negligible heat flow in the direction perpendicular to the plate. Let T1, ... , T4 denote the temperatures at the four interior nodes of the mesh in the figure. The temperature at a node is approximately equal to the average of the four nearest nodes-to the left, above, to the right, and below. For instance,

What current is drawn from the household circuit by a 2000 W
electric heater? What is the resistance of the electric heater? If the resistance of
the cables is 0.3 ohm, what is the power lost in the cables? (Symbolic answers are
necessary! The voltage is 240 V)

Four charged particles are placed at the corners of a square of side a. The
charges are the following: -2Q (left top), 3Q (right top), 3Q (left bottom), -2Q
(right bottom), Q > 0. Calculate the forces acting on each charge. Indicate the
direction of these forces on the graph. Evaluate the formulas for the forces for
Q = 1 uC.
