No it does not have a timing belt
Answer:
Explanation:
As we know that the rate of heat transfer due to temperature difference is given by the formula
here we know that
A = 4 m x 7 m
thickness = 30 cm
temperature difference is given as
now we have
Blue-violet light on the visible light spectrum can cause damage to retina cells, increasing one's risk of developing age-related macular degeneration, explains Essilor.
Answer:
A) Gravitational Force is greater in S.
B) Time taken to fall a given distance in air will be greater for F.
C) Both will take same time to fall in a vacuum.
D) Total force is greater in S.
Explanation:
(a) In this case, the gravitational force of S will be greater, because Newton's Second Law states that - F = ma, or weight =mg. g is constant. And mass of the solid metal is heavier.
(b) In this case, the time it will take for F to fall from a given distance in air will be greater than that of S, since the air resistance is not negligible (as in the case of S).
(c) In this, It will take same time for S and F because in a vacuum, there are no air particles, so there is no air resistance and gravity is the only force acting and so objects fall at the same rate in a vacuum.
(d) The total force will be greater in S than F because Force=ma and S is of heavier mass than F.
