The correct answer is C) towards the center of the circle.
Although the object is moving at a constant speed it is constantly accelerating due to the constant change in direction as it describes the circular path. This causes a constant change in velocity as velocity is a vector quantity.
For the object to maintain the circular path there has to be centripetal force acting on the object and this centripetal force is directed towards the center of the circle.
Answer:
I believe it's false. Why would it increase?
Explanation:
Answer:
Average speed equals distance / time
380 / 40 = 9.5 m/s.
Explanation:
Answer: 0.4 km/h
100 m = 0.1 km
15min./60min. = 0.25 hr
so, divide the total distance (100 m) by the total time (15 min)
0.1 km/0.25 hr = 0.4
Answer:
The period of the harmonic vibration is inversely proportional to its frequency
Explanation:
The period of the simple harmonic vibration is actually the inverse of its frequency.
This means that, to get the period, all you have to do is divide "1" by the frequency, in other words:
period = 1/frequency
From this formula, we can note that as the frequency increases, the period decreases and vice versa.
Based on this, the relation between the period and the frequency is an inversely proportional relation.
Hope this helps :)
