Answer:
Step-by-step explanation:
Given
Position of particle is
i.e. distance from x axis is
Distance from y axis at
velocity is given by
Similarly acceleration is given by
Magnitude of acceleration is
From 1 and 2 we can see that
Magnitude of acceleration is proportional to distance from x axis
Answer:
B
Step-by-step explanation:7 is greater than 2
No graph, so cannot be precise.
But you can apply rotation 270 CCW = rotation -90 CCW
r_[90] : (x,y) -> (y,-x)
Answer:
60 degrees
Step-by-step explanation:
We know that a right triangle is 90 degrees
We have one angle given of 30 degrees
90 degrees - 30 degrees (known angle) = 60 degrees (unknown angle)
Therefore the unknown angle is 60
