As velocity at t = 2 s is v = 2*2i + 2*2j = 4i + 4j Now momentum p = mv = 8i + 8j

How many physical dimensions do we have?
In everyday life, we inhabit a space of three dimensions. but Generally, there are 4 dimensions (x,y,z:t) 3 axis and 4th is time. Mathematically there is N dimensions.

Force of 16N and 12N are acting on a mass of 200kg in mutually perpendicular directions. Find the magnitude of the acceleration produced.
Resultant force F= sqrt (16^2+12^2) => F=20N So F=ma => a=F/m=20/200 => a=0.1 ms-2

According to principle of conservation of energy, the total momentum of a system of masses in any direction remains constant unless acted upon by an external force in that direction. A. True B. False
This is not principle of conservation of energy but it is principle of conservation of momentum.

will gravity will be quantized or not ? if not then universe will be still probablistic ifquantum mechanics already introduces randomness ? so if gravity wont quantized still universe will be probabilisitc ?
Gravity is the force with which all objects attracted to the Earth. This force is expressed in terms of G that is universal gravitational constant This conveys that Earth's force of gravity can be quantized....
