Answer:
False
Explanation:
It is not necessary, that when the initial speed of the object is zero then it must be at origin.
It may be the object starts motion from the left of origin.
To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by
Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And
Therefore using the values given we can find the velocity through,
Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1
Therefore the cars goes to 145.3m/s
It is the energy an object has because of its motion.
The filter would need to absorb every color EXCEPT yellow. It would have to absorb red orange green blue and violet.
So if the formula for work is force times displacement times cosine(theta), you'd plug in the numbers
100x5 (since there's no angle in the problem, cosine(theta) isn't used
100x5 = 500
So the answer would be B.
Hope that helps!
