Answer: amount = 2466.95L
Explanation:
given that the speed is = 1900./kmh i.e. 1hr/900km
distance = 1050km
the fuel burns at a rate of 74.4 L/min
therefore the amount of fuel that the jet consumes on a 1050.km becomes;
total fuel used = time × fuel burning rate
where time = distance / speed
∴ total fuel used (consumed) = time × fuel burning rate
total fuel consumed = (1050km × 1hr/1900km) × (60min/ 1hr × 74.4L/1min)
total fuel consumed = 2466.95L
Answer:
The most mass of an atom is found in its nucleus(proton + neutron) since the mass of the electrons is negligible
to give you an estimate, protons are pretty small and electrons weigh about 1/2000 the mass of a proton
Answer:-
(iv) (i) + (II)
Explanation:-
Hydrogen bonds Occur between Hydrogen and an element with high electronegativity like N or O.
DNA base pairs are arranged such that they are complimentary. Hence hydrogen bonding will occur between both the amide carbonyl and NH2 as well as the amide NH and Nitrogen of the cyclic C=N-C group.
