This actually means that the object which is emitting light spectrum is moving away from us.. how do you know that ? well.. it is clearly mentioned that it is a red shift so the wavelengths will stretched more . and thus the spectrum turns more reddish as it has higher wavelengths .. hence so called red shifts
Answer:
There is a right angle and it has three sides.
Explanation:
There are two 45 degree angles and since a triangles sides ALWAYS add up to 180 we know the the other side has to be 90 degrees because 45+45+90=180. And we know that every triangle has three sides because "tri" means three.
(a)
The tangential acceleration component of the car is simply equal to the change of the tangential speed divided by the time taken:
This rate of change is already given by the problem, 0.800 m/s^2, so the tangential acceleration of the car is
(b)
The centripetal acceleration component is given by
where
v is the tangential speed
r is the radius of the trajectory
When the speed is v = 3.00 m/s, the centripetal acceleration is (the radius is r = 10.0 m):
(c)
The centripetal acceleration and the tangential acceleration are perpendicular to each other, so the magnitude of the total acceleration can be found by using Pythagorean's theorem:
and the direction is given by:
where the angle is measured with respect to the direction of the tangential acceleration.
Answer:
Capacitivie reactance is the angular frequency
