Explain Scalars and Vectors
This is one of the harder ideas to get used to when you start learning physics. The trick is to see that there is one basic difference between a scalar and a vector.
A scalar can be described by only a number and a unit, sometimes, these two are lumped together and called the magnitude.
Here are some scalar quantities:
Vectors are a scalar quantity plus another part which tells the direction. To wrote a vector you need the number and unit part, magnitude plus a direction. When vectors are being represented by letters the letters appear in bold face like x, a, and i, and scalars will be standard letters like x, a, and i.
Example: your position from a certain point on a map is a vector, needs size and direction included, whereas your temperature only needs a size. Don't sweat this now just refer to it later when it comes up.
Focal length of convex lens is 0.1 m. A liquid lens is formed between a plane surface and one face of this lens of radius of curvature 0.12m. The converging combination formed is f
An aereplane has velocity 500m/s with respect to air. Wind blows with velocity 20m/s along north. Then in what direction pilot should be heading so as to go along North-east direct

When is the combination of cells advantageous and why? (Mar 2009) What do you mean by internal resistance of a cell? Write down the value of internal resistance of an ideal cell
The temperature co-efficient of resistance: The temperature co-efficient of resistance is defined as; The Fractional change in resistance from 0ºC, per degree temp
Direct Current (DC): Such a current can be getting by connecting the two ends of a conductor to the terminals of the battery. This current doesn't change the direction

There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "cent
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
If W is atomic weight and N is the atomic number of an element, then: (1) Number of e -1 = W- N (2) Number of 0 n 1 = W- N (3) Number of 1 H 1 = W-N (4) Number of 0
