Answer:
The new speed is 1230.28 m/h
Explanation:
The jet airliner moving initially at 503 mph to the east
The wind is blowing at 855 mph in a direction 52° north of east
At first let us distribute the velocity of the wind into east component
and north component
→ The east component is 855 cos(52) m/h
→ The north component is 855 sin(52) m/h
Now we have two components of velocity in the east direction
and one component of velocity in the north direction
The new speed is the resultant of the east and north components
→ The east components are 503 m/h and 855 cos(52) m/h
→ The north component is 855 sin(52) m/h
Add the components of the speeds in direction of east
→ The east component = 503 + 855 cos(52) = 1029.39 m/h
→ The north component = 855 sin(52) = 673.75 m/h
Now we can find the new speed as a resultant speed of the east and
north components
→ The new speed =
→ The new speed = 1230.28 m/h
<em>The new speed is 1230.28 m/h</em>
Mendeleev watched that tellurium has compound properties like different components in its gathering, and he didn't realize that neutrons cause the more noteworthy nuclear mass. Mendeleev expressed that he anticipated that tellurium would have a lower nuclear mass than iodine.
A. because ecosystem can be like hot, humid, cold, exc.
