Answer:
Explanation:
well if its an electromagnetic current you would increase the battery voltage basically by using two batteries
The answer is D because i'm in the same studies right now.
Answer:
v = 134.06 m/s
Explanation:
Given that,
Radius of a circular track is 1,835 m
Time required to complete one lap around a perfectly circular track is 86 seconds
We need to find the car's velocity. Velocity is equal to,
v=d/t
On circular path,

So, car's velocity is 134.06 m/s.
Answer: A. vector
Explanation:
Movement is the change of position of a body at a certain time. The body that experiences this change of position is called mobile.
In this sense, the <u>displacement</u> is the distance in a straight line between the initial and final position of this mobile, which differentiates it from <u>the trajectory, </u> which is the <u>path followed by the body in its movement and a scalar magnitude.</u>
Hence, the displacement is a vector.
