Answer:
250 m
Explanation:
The car in this problem is moving of uniform accelerated motion, so we can use the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time
a is the acceleration
Assuming the car starts from rest,
u = 0
Also we know that
a = 5 m/s^2 (acceleration of the car)
t = 10 s
Substituting, we find the distance covered:
Explanation:
The given data is as follows.
Voltage = 2.50 V
Hence, calculate the equivalence capacitor as follows.
=
C =
Now, we will calculate the charge across each capacitance as follows.
Q = CV
=
=
=
Thus, we can conclude that is the charge stored on each given capacitor.
Answer:
The third choice:
Explanation:
The cork is positively charged, therefore we know tat there must be excess of positively charged protons present.
The charge of a proton is
;
therefore, the number that makes up a charge of
is
which is the 3rd choice.
