Answer:
The velocity 
of the cart with respect to the ground is
if we consider North the positive y-direction and East the positive x-direction.
Explanation:
We have for relative motion the following expression:
Where is the velocity of the cart with respect to the ground, 
is the velocity of the cart with respect to the plane and 
is the velocity of the plane with respect to the ground.
We find that:
Thus:

X-rays have shorter wavelength than visible light. But that's hardly the reason that they're used for medical imaging. xrays have much higher frequencies then visible light which means they have much greater penetrating ability. with xrays you can see inside the body. you can't do that with a visible flashlight no matter how bright and powerful it is.

Adaptation will mean taking action to minimize the negative effects of change. ... the use of new tools and techniques for decision-making, For example, projected increases in drought, fire, windstorms, and insect and disease outbreaks are expected to result in greater tree mortality. Fewer trees will reduce Canada’s timber supply, which in turn will affect the economic competitiveness of Canada’s forest industry. This would leave forestry-dependent communities vulnerable to job losses, closure of forestry processing facilities and an overall economic slump.
