True. Series resistance will add up and high total resistance means less current
Explanation:
Given that,
Position of the particle at t = 0,

Velocity of the particle at t = 0

Acceleration of the particle,

Solution,
(a) Let v is the velocity at t = 10 s. Using the equation of kinematics as :



(b) Let y' is the position at t = 1 s. Again using second equation of kinematics as :



(c) Magnitude of y',

|y'| = 21.69 meters
Direction of the y',



Hence, this is the required solution.
Answer:
According to your question although I think an object undergoing uniform circular motion is moving with a constant speed. Nevertheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards,therefore a force perpendicular to an objects velocity change the direction of the velocity but not its magnitude.
The answer might be B because the value is negative, and negative could mean slowing down.
