Answer:
Private jet is 200 mph
Commercial jet is 225 mph
Explanation:
Let the speed of private jet be x mph therefore the speed of commercial jet will be 2x-175 mph
The distance is the same
Speed is distance per unit time hence distance is product of speed and time
Distance by private jet is 9x
Distance by commercial jet is 8(2x-175)
Since the distance is the same
9x=8(2x-175)
9x=16x-1400
7x=1400
X=200
Then 2x-175= 400-175=225
Speed of private jet is 200 mph while commercial jet is 225 mph
Answer:
The recipe for a hurricane is a combination of warm, humid wind over tropical waters. The temperature of tropical waters must be at least 80 degrees F for up to 165 feet below the ocean’s surface. As this warm water meets the wind that blows west from Africa across the ocean, it causes the water to vaporize. The water vapor then rises into the atmosphere, where it cools and liquefies.

The energy absorbed by photon is 1.24 eV.
This is the perfect answer.
Answer: C) the energy gained by an electron in moving through a potential difference of 1 volt
Explanation: In order to explain this response we have to consider that the potential energy for any charge is given by:
Up=q*ΔV then if we consider an electron accelerate by a difference potential of 1V, we have:
Up=e*V ( energy UNITS, which is equal to 1.6*10^-19 J).
The option A) and B) are wrong because elentron Volt has units of energy not force.
The option D) is also wrong because the the work done to move un electron one meter also depends of the magnitud of the potential difference ( electric field) where the electron is moving .
Finally the option D) is false because the one C*V is one J, is huge quantity of energy compared to the electron Volt (eV).
