In solids, heat is move from conduction. We will study conduction of heat energy by a solid bar in the following section.
Given a solid bar of thickness and area of cross-section A. The left side of the bar is get at a temperature ΦA and right side at ΦB.
Let us consider that ΦA > ΦB.
Heat moves from high to low temperature i.e., from left side to right side, as given in fig.
After some time, temperature of each section becomes constant with time. This is called as steady state.
Like the centre of mass, the moment of inertia is a function of a body that is concurrent to its mass distribution. Moment of inertia gives a measurement of the resistance of a bod
Vibratory and Oscillatory Motion : To and fro or back and forth motion of an object is known as vibratory and oscillatory motion.
What is a hypothesis for a Hooke''s Law experiment which was completed with a single, series and parallel spring arrangement?
1). A ring of outer diameter 80 cm is made from square of cross -section steel bar size(8 *8 cm) . If relative permeability 1200 for steel . calculate the current needed to produce
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
Characteristics of a Transmitted Pulse The below animation depicts the boundary behavior of a pulse that is moving along a less dense incident and medium towards that is approa

Twin paradox: One of the most popular "paradoxes" in history, predicted trhough A. Einstein's special theory of relativity. Take two twins, born on the similar date on Earth.
