Acceleration of a particle is given by is equal to 3 + 23 + 2 where t is in seconds if the particle starts with velocity V is equal to 2 metre per second at x is equal to zero then find the velocity at the end of 2 secondsdefine relative velocity deduce an expression for relative velocity of one object with respect to another in terms of velocity is relative to the earth ​

the reference material is water then a substance with a relative density (or specific gravity) less than 1 will float in water. For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink.

To calculate the expression of relative atomic mass and relative molecular masses, you need to consider the mass of each individual atoms in the molecules of the element.

=> Relative molecular mass or molecular weight is the mass of a molecule. It is calculated as the sum of the relative atomic masses of each constituent element multiplied by the number of atoms of that element in the molecular formula. HOPE IT HELPS U. Mark me as Brainlist

a.

the relative velocity is defined as the velocity of moving body with respect to another moving body in a certain direction .

b.

the expression of relative velocity are going two bodies are moving in the opposite direction I went to bodies move in the same direction

answer:

Let the two object are A and B

Defination: The relative velocity of an opbject A with respect to anolther object B is the velocity that object A would appear to have to an observer situated on object B moving along with it.

Explanation:

(a) Relative velocity  of body A with respect to body B is defined as the time rate of change of position of A wrt. B.  (b) (i) When two objects move in the same direction   (ii) When two objects move in the opposite direction  (c) Velocity of the Jet plane VJ =500km/hr velocity of gases wrt. Jet plane VgJ = - 1500km/hr (direction is opposite)  Velocity of the Vg = -1500 + 500 = -1000km/hr   (As hot gases also comes out in opposite direction of the Jet plane)
