Explanation:
(a) Formula to calculate the capacitance is as follows.
Now, putting the given values into the above formula as follows.
= 0.291
or, = ln (0.291)
= -1.23
C = 0.729 F
Hence, the value of capacitance is 0.729 F.
(b) Formula to calculate the constant of circuit is as follows.
T =
=
= 2.259 sec
Therefore, the time constant of the circuit is 2.259 sec.
The figure shows the arrangement of given data.
The displacement is considered along X direction and time along Y direction.
The slope of the graph is given by tan θ
So tan θ = Δx/Δt = Velocity between those two points considered for finding slope of graph.
So slope of position time is graph is equivalent to kinematic quantity Velocity.
The two forces of gravity are equal
Explanation:
We can answer this question by applying Newton's third law of motion, which states that:
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
In this problem, we can identify the Sun as object A and the Earth as object B. This means that the force of gravity exerted by the Sun on the Earth is the action, while the force of gravity exerted by the Earth on the Sun is the reaction: according to Newton's third law, these two forces are equal and opposite.
Therefore, the two forces of gravity are equal in magnitude, which is given by:
where
G is the gravitational constant
M is the mass of the Sun
m is the mass of the Earth
r is the separation between the Earth and the Sun
