let the plane is flying at some angle theta with west towards north
Now we can use the components


now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say



so plane has to fly in direction 14.5 degree North of west
Explanation:
what?? do you please say clearly
Answer:
925.04 J/s
Explanation:
T = 80 C = 80 + 273 = 353 K
To = 20 c = 20 + 273 = 293 K
A = 2 m^2
Use the formula for Stefan's law
Energy radiated per second


E = 925.04 J/s
Answer:
If you add the 2 velocity vectors you get the velocity of the third vector which is the (change in) velocity of the cue ball after striking the cushion
V * 2 * cos 45 = 4 * cos 45 = 2.83 m/s
