Answer:
d) is the same as when it started from rest
Explanation:
using equation of motion
v = u + at
second law of momentum defines
F = ma
a = F /m
the equation becomes
v = u + (F/m)t
from hear
since v is directly proportional to the force and the force remain the same, the increase in the cart speed will also remain the same.
Answer:
B. Cant stop things from going wrong.
Explanation:
To me it's the only reasonable answer...
Answer:
An object has the MOST kinetic energy when it's movement is the GREATEST.
Explanation:
Answer
given,
capacitance = C = 3.4-µF
inductance = L = 0.08 H
frequency is expressed as

time period

after time T/4 current reach maximum



t = 8.2 x 10⁻⁴ s
t = 0.82 ms
b) using law of conservation





I = 0.010 A
I = 10 mA
