Answer:
Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. <em><u>The light produced by the flame is energy, not matter.</u></em>
<em><u></u></em>
As per FBD while its accelerating upwards
we can say that

here normal force is given as


now mass is given as


now we will have


Now while accelerating downwards we can say by FBD

again plug in all values


Answer:
Option (a), (b) and (c)
Explanation:
The resistance of a conductor depends on the length of the conductor, area of crossection of the conductor and the nature of the conductor.
The formula for the resistance is given by
R = ρ x l / A
Where, ρ is the resistivity of the conductor, l be the length of the conductor and A be the area of crossection of the conductor.
So, It depends on the length, area and the type of material.
Explanation:
Work is the product of force and distance.
W = F×d
W = (22 N) × (16 m)
W = 352 J
Answer:Physics. Distance, the total distance an object travels dependent on its path through space. Optical path length, the product of the distance light travels and the refractive index of the medium it travels through. Mean free path, the average distance that a particle travels before scattering.
