What is the dominating heat transfer mechanism within solid materials?
The dominating mechanism of heat transfer within solids is called conduction.
How to obtain the acceleration of an object from its velocity equation?
To obtain the the acceleration, you need to take a first order derivative of your velocity equation with respect to time.
Subject: Differential Equations
How many conditions do you need to solve a time-dependent second order differential equation?
To solve a second order differential equation, say in x and y direction, you would need to boundary conditions in each direction. For the temporal term in your equation, you need an initial condition. Therefore, a total of maximum 5 conditions are needed.
