Compute the components of the given vectors. Let
denote the plane's velocity vector, and
the wind. Then



The resultant velocity (rounded) is

with magnitude
and direction
, or about 258 mi/hr at 47.7 degrees south of east.
Answer: the rider’s pedal force must be greater than friction and the force of gravity
Explanation:
This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.
Answer:
5.03 m
Explanation:
The wavelength of a wave is given by

where
v is the speed of the wave
f is the frequency of the wave
For the sonar signal in this problem,


Substituting into the equation, we find the wavelength:

Answer: 15.29
Explanation: there you go have a nice day (*^p^*)
Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis.
