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.
Answer:
a= 1.59 m/s² : Magnitude of the acceleration
β = 65.22° (north of east) : Direction of the acceleration
Explanation:
Conceptual analysis
We apply Newton's second law:
∑F = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Problem development
The acceleration is presented in the direction of the resultant force applied .
Calculation of the resultant forces (R)
R= 429.5 N
We apply the formula (1) to calculate the magnitude of the acceleration(a) :
∑F = m*a , m= 270 kg
R= m*a
429.5 =270*a
a= 1.59 m/s²
Calculation of the direction of the acceleration (β)
β = 65.22° (north of east)
Answer:
A) the liquid particals move slower
Explanation:
vapor has a higher temp and have more energy than liquid so it's not c or d. and liquid has a lower boiling point than vapor
B. 500ft. If you are driving at night with high beams on you must dim them within 500 feet of an oncoming vehicle.
