Answer:
966 mph
Explanation:
Using as convention:
- East --> positive x-direction
- North --> Positive y-direction
The x- and y- components of the initial velocity of the jet can be written as
![v_{1x} = 406 mph\\v_{1y} = 0](https://tex.z-dn.net/?f=v_%7B1x%7D%20%3D%20406%20mph%5C%5Cv_%7B1y%7D%20%3D%200)
While the components of the velocity of the wind are
![v_{2x} = (568)(cos 15^{\circ})=548.6 mph\\v_{2y} = (568)(sin 15^{\circ})=147.0 mph](https://tex.z-dn.net/?f=v_%7B2x%7D%20%3D%20%28568%29%28cos%2015%5E%7B%5Ccirc%7D%29%3D548.6%20mph%5C%5Cv_%7B2y%7D%20%3D%20%28568%29%28sin%2015%5E%7B%5Ccirc%7D%29%3D147.0%20mph)
So the components of the resultant velocity of the jet are
![v_x = v_{1x}+v_{2x}=406+548.6=954.6 mph\\v_y = v_{1y}+v_{2y}=0+147.0=147.0 mph](https://tex.z-dn.net/?f=v_x%20%3D%20v_%7B1x%7D%2Bv_%7B2x%7D%3D406%2B548.6%3D954.6%20mph%5C%5Cv_y%20%3D%20v_%7B1y%7D%2Bv_%7B2y%7D%3D0%2B147.0%3D147.0%20mph)
And the new speed is the magnitude of the resultant velocity:
![v=\sqrt{v_x^2+v_y^2}=\sqrt{(954.6)^2+(147.0)^2}=965.8 mph \sim 966 mph](https://tex.z-dn.net/?f=v%3D%5Csqrt%7Bv_x%5E2%2Bv_y%5E2%7D%3D%5Csqrt%7B%28954.6%29%5E2%2B%28147.0%29%5E2%7D%3D965.8%20mph%20%5Csim%20966%20mph)
Answer:
When it’s gravitational
Explanation:
I’m pretty sure that’s the answer
Heat, like sound, is kinetic energy. Molecules at higher temperatures heave more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
So the answer is A.
B acid rain in an area kills fish in a lake
Answer:
yes
it does you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles. These forces change right back when you return to your original latitude.
