It says about 360 degree by Thita Degree, which I did not understand. It gives a definition which is very difficult for me to understand. It says " The object and the image formed by the two mirrors will lie on the circumference of a circle with centre at the point of intersection of the two mirrors and radius equal to the distance of object from the point of intersection. ""
Please explain what that whole section means. As I find that the portions that you have put in this website does not cover everything. It just explains some basic things but does not explain as per the text we refer to.
Infact you should have referred to various books of ICSE syllabus and should have explained each and everything point without missing anything.
what is resistivity ? and what is resistance ? differentiate between the two..
Why does an iron nail sink in water but the ship made of iron floats?I am bit confused in what my teacher told me and what my friends. Help please?
What is the principle of screw gauge?
Derive the equation P=h.p.g
A ball is thrown vertically upwards from the top of a tower with an initial velocity of 19.5 m/s. The ball reaches the ground after 5 seconds. calculate :
1 - the height of the tower
2 - the velocity of ball reaching the ground. Take g=9.8m/s2
differentiate between acceleration and retardation
how to solve the numerical on vernier callipers ? question is:In a vernier callipers 19 main scale divisons concides with 20 vernier scale divisons. IF the main scale has 20 divisons in a centimetre,calculate 1) pitch 2) lest count of vernier callipers
Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
it is easier to lift heavier stone under water than air. why?
An object is placed between two plane mirrors inclined at an angle of 50o. Find the number of images formed.
weight is measured by spring balance then why gold is not weighed by spring balance?
Please explain this question -
Example 3:
The kinetic energy of a block of mass 3 kg is 150 J. Find its momentum.
Solution:
It is given that:
Kinetic energy (k) of the block = 150 J
Its mass,m= 3 kg
Let the velocity and momentum of the block bevandprespectively.
We know that:
k= 0.5mv2... (1)
p=mv... (2)
Using equation (1), we get:
two bodies A and B of same mass are moving with velocities v and 2v respectively .compare their (I) inertia and (iii) momentum
