Acar is stopped at a red light. the light turns green, and the car begins to move. after 6 seconds, the car traveling at 20m/s. how far did the car travel?

60 m

Explanation:

From the set of kinematics equations you can use,

s = [(u+v)/2]×t

  = [ (0+20)/2 ]×6 = 60 m

where all terms in usual meaning.

here u = 0 as initially car is at rest.

as technology advances, new experiments often expose problems in accepted theories. c

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
