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 given statement is false.
Explanation:
Weight :It is defined as the measure of force exerted upon the object by the gravity. It is measured in Newtons.
, where W= Weight , m = mass of the object , g = acceleration due to gravity = 
Here the given statement is False, the correct statement will be:
The density of a substance is defined as its mass divided by its volume.
Sodium Flouride
Magnesium Nitrate
Calcium Phosphate
Sodium Oxide
Lead Iodide
Copper Sulphate
