Answer:
The resultant velocity is <u>169.71 km/h at angle of 45° measured clockwise with the x-axis</u> or the east-west line.
Explanation:
Considering west direction along negative x-axis and north direction along positive y-axis
Given:
The car travels at a speed of 120 km/h in the west direction.
The car then travels at the same speed in the north direction.
Now, considering the given directions, the velocities are given as:
Velocity in west direction is,
Velocity in north direction is,
Now, since are perpendicular to each other, their resultant magnitude is given as:
Plug in the given values and solve for the magnitude of the resultant.This gives,
Let the angle made by the resultant be 'x' degree with the east-west line or the x-axis.
So, the direction is given as:
Therefore, the resultant velocity is 169.71 km/h at angle of 45° measured clockwise with the x-axis or the east-west line.
A chemical change. chemical changes could cause changes in shapes or sizes
In transistor,
Emitter current is equal to the sum of base current and collector current.

Answer:
It's actually (B).
Explanation:
because if there going at a constant speed you would being going the same distance as all the other and that's why the answer be is real event because of the Constance of the striate line going at a slow speed and then gaining speed again. Hope this did Help
