Answer:
The correct option is "Zero". A further explanation is given below.
Explanation:
As we know,
The capacitor is given by:
⇒
Rate of change with respect to the time will be:
⇒
Now,
It is mentioned in the question that the capacitor is completely charged, then
⇒
i.e.,
⇒
All other choices available aren't related to that same scenario in question. So the answer above is the perfect one.
Answer:
a) w= 6 rad/day b) v = 2 10² m
Explanation:
Let's use angular kinematic relationships
a) The angular velocity is
W = θ / t
t = 1 day (24 h / 1 day) (3600s / 1 h) = 86400 s
w = 2π / 86400
w = 7.27 10⁻⁵ rad / s
Reduce to rad / day
w = 7.27 rad / s (3600s / 1 h) (24 h / 1 day)
w = 6.28 rad / day
w= 6 rad/day
b) the linear velocity is
v = w r
Mercury radius is
r = 2.43 106 m
v = 7.27 10⁻⁵ 2.43 10⁶
v = 1.76661 10² m / s
v = 2 10² m
Answer:
velocity of mass when it slides of will be 1.36 m/sec
So option (b) will be correct option.
Explanation:
We have given mass of the slits m = 75 gram = 0.075 kg
Radius r = 75 cm = 0.75 m
Coefficient of kinetic friction
Acceleration due to gravity
When the mass slides of
So velocity of mass when it slides of will be 1.36 m/sec
So option (b) will be correct option.
Meselson and Stahl
<u>Explanation:</u>
<u></u>
The classic experiment that supported the semiconservative model of dna replication was performed by Matthew Meselson and Franklin W. Stahl. In this model, the two strands of DNA unwind from each other, and each acts as a template for synthesis of a new, complementary strand. This results in two DNA molecules with one original strand and one new strand. They used E. coli bacteria as a model system.
