An airplane is flying north with an airspeed of 200 km/h when it encounters a crosswind of 70 km/h toward the east. which expression gives the resultant speed of airplane?

211.89 km/h

Explanation:

Given that,

The speed of an airplance in North direction = 200 km/h

Speed in East direction = 70 km/h

We need to find the resultant speed of the airplane. It can be calculated as the resultant of the two velocities as follows :

So, the required speed is 211.89 km/h.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
