Answer: option D. 4
Reasoning:
Assuming that the time elapsed between any two consecutive dots is the same, and that the second dot marks second 1, the column with 3 dots marks second 2, and the dot right most marks second 3, the motorcycle has positive acceleration after 4 seconds.
That is because:
1) from the first dot to the second dot: the velocity the lenght of the arrow that models the velocity decrases, which means that the acceleration is negative.
2) In the nex group of dots the length of the arrow remains equal, which means that the velocity is constant and the acceleration is 0.
3) For the last dot, the length of the arrow is greater, which means that the velocity increases, and so the acceleration is positive.
I think that the importance of time is to allow there to be order. People need to be somewhere at a certain time and not just whenever they want. It allows people to get things done more efficiently. <span />
<h3>Answer: 22.48°</h3><h3 /><h3>Explanation:</h3>
refractive index = sin i / sin e
where i is the angle of incidence
e is the angle of refraction
1.5 = sin 35 / sin e
1.5 = 0.5736/sin e
sin e = 0.5736/ 1.5
sin e = 0.3824
e = 22.48°

Answer:if the object is in motion it will continue its constant velocity and if it is in rest it will remain in rest
Explanation:
Answer:
The inductance of the inductor is 3.2 mH.
Explanation:
Given that,
Current = 0.560 A
Angular frequency = 280 rad/s
Voltage = 0.500 V
We need to calculate the inductance
Using formula of inductance
Put the value into the formula
Hence, The inductance of the inductor is 3.2 mH.
