C.the acceleration is doubled
Answer:
The pitch will progressively lower
Explanation:
If i were bungee jumping from a bridge while blowing a hand-held air horn and someone who remains on the bridge will hear a decreased pitch or frequency as the source is moving away from the stationary listener as per the Dooplers effect. Hence, the pitch will progressively lower as the source is moving away from the observer.
Answer:
Wait, that can happen? I'm sorry.
Explanation:
Since, the options are not given the question is incomplete the complete question is as follows.:
Which of the following is a major way in which oceans contribute to weather systems?
provide a diverse habitat for many organisms
experience changes in amounts of dissolved salts
store and transport the Sun's heat energy
reach depths that can be as much as 12000 meters
Answer: Store and transport the Sun's heat energy.
Explanation:
Oceanic currents are just like a conveyor belt. It helps in transportation of the warm water and the precipitation from the equator to the poles and the cold water in the poles towards the tropics. This way the oceans counteract the uneven distribution of the radiation of sun that reaches upto the surface earth. This will regulate the global climate.
Answer:
The acceleration is ![a =51945 \ km/h^2](https://tex.z-dn.net/?f=a%20%3D51945%20%5C%20km%2Fh%5E2)
Explanation:
From the question we are told that
The lift up speed is ![v = 147 \ km/h](https://tex.z-dn.net/?f=v%20%20%3D%20147%20%5C%20%20km%2Fh)
The distance covered for the take off run is ![s = 208 m = 0.208 \ km](https://tex.z-dn.net/?f=s%20%3D%20%20208%20m%20%3D%200.208%20%5C%20km)
Generally from kinematic equation we have that
![v^2 = u^2 + 2as](https://tex.z-dn.net/?f=v%5E2%20%3D%20u%5E2%20%2B%202as)
Here u is the initial speed of the aircraft with value 0 m/ s give that the aircraft started from rest
So
![147^2 = 0^2 + 2* a* 0.208](https://tex.z-dn.net/?f=147%5E2%20%3D%200%5E2%20%2B%202%2A%20a%2A%200.208)
=> ![a =51945 \ km/h^2](https://tex.z-dn.net/?f=a%20%3D51945%20%5C%20km%2Fh%5E2)
