Answer
a. These are objects in motion that have kinetic energy.
Explanation:
Answer:
35.55 ohm
Explanation:
C = 80 micro farad
F = 56 hertz
Reactance
Xc = 1 / (2 × pi × F × C)
Xc = 1 / ( 2 × 3.14 × 56 × 80 × 10^-6)
Xc = 35.55 ohm
Heya!!
For calculate velocity, lets applicate formula

<u>Δ Being Δ</u>
d = Distance = 3790 m
t = Time = 249 s
v = Velocity = ?
⇒ Let's replace according the formula and clear "v":

⇒ Resolving

Result:
The velocity is <u>15,22 meters per second.</u>
Good Luck!!
Explanation:
⠀
⠀
(a) <u>The</u><u> </u><u>segment</u><u> </u>A shows acceleration as velocity increases with the increase in time.
⠀
⠀
⠀
(b) <u>The</u><u> </u><u>segment</u><u> </u>C shows the object is slowing down as the time increases in segment C, the velocity decreases and afterwards it comes to rest.
⠀
⠀
⠀
(c) The velocity is segment B is <u>4</u><u>0</u><u>m</u><u>/</u><u>s</u><u>.</u> And in the diagram there is no change in velocity.
⠀
⠀
⠀
(d) The acceleration of segment B is <u>zero</u><u>.</u> As there in no change in curve and it is moving with uniform velocity.
