Component Addition of vector
We learned in which vectors oriented at right angles to one another could be added together by using the Pythagorean Theorem. For example, two displacement vectors along with magnitude and direction of 11 km, north and 11 km, East can be added together to generates a resultant vector which is directed both north and east. While the two vectors are added head-to-tail as display below,
c). at what speed does it hit the ground? d). what total length of time is the ball in the air
Motion of an object in a plane is called two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be explained by two elements in any two mutually perpendicular d

Explain the working of a refrigerator A refrigerator is the reverse of a heat engine. Here the working substance extracts heat Q2 from the cold reservoir at temperature T2, som
Explain the Merits of Vacuum Diode over Semiconductor Diode (i) Vacuum Diodes can withstand high reverse voltages (ii) Vacuum Diodes can operate at fairly high temperature
Surface gravity on Mars is roughly 1/3 that of the Earth. Consider you drop a rock initially at rest from a height Hm on Mars and it takes a time tg to hit the ground. From what he
(i) X-rays are electromagnetic waves with wavelength lie among 0.1Å - 100Å. (ii) X-rays is invisible. (iii) They always go in a straight line with speed of light. (iv) X
Ammeters : Ammeters are used to measure current flow, as such they need to be inserted in series with the circuit under test so that the current to be measured flows through th
