Question

The construction of a ∆ABC in which AB=5cm, angleA=60°is not possible when difference of BC and AC is equal to​

Answer 1

Step-by-step explanation:

Derivation of Conservation of Momentum

Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)

Answer 2

$\huge\underline\bold\orange{Ans}$

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat:

"the final transfer of energy to the surface is by convection"
