Answer:
The helicopter uses 35 gallons to fly for 5 hours.
Explanation:
The amount of gas that a helicopter uses for flying varies directly proportional to the number of hours spent flying.
g ∝ T
where g represents amount of gas and T time of flight.
Then,
The helicopter files 4 hours and uses 28 gallons of fuel.
Here, g₁= 28 gallons, T₁=4 hours
g₂=?, T₂=5 hours.
⇒28×5= g₂×4
⇒ g₂×4=28×5
gallons
The helicopter uses 35 gallons to fly for 5 hours.
I don't know what " hm/h " means as a unit of speed. But if the bright red object is traveling in a straight line at a constant speed, then its acceleration is zero, and that means that the net force acting on it is zero. The same would be true of a car of any other color traveling with the same velocity.
Answer:
<u>True</u>
Explanation:
Many nuclear scientists believe that when fusion power is used in powering spacecraft, this will shorten the travel time to planetary bodies.
However, one may wonder: <em>what is fusion power? </em>In simple words, it is a form of energy that uses heat released when lighter elements combine together to form heavier elements. In this fusion process, a huge amount of energy is released which can be harnessed and termed fusion power.
