Answer:
The length is
and the angle is 
Explanation:
The period
of the pendulum is related to its length
by

where
is the acceleration due to gravity.
Solving for
we get

putting in
and
we get:


There are two forces acting on the pendulum: The gravitational force
and the
student's force. Therefore, the angular displacement
that these forces give is


putting in
,
, and
we get


Answer: a tadpole is the first or second step into the evolution for a frog
Explanation: a frog starts with the egg then it becomes a tadpole for 6 to 12 weeks before it can start going out the water.
Charles's <span>law is also known as the law of volumes explained the relation between the volume of gas and its temperature.
Charles's law states that: " At constant pressure, the volume of a certain mass of gas is directly proportional to its temperature in kelvin".
This means that:
V = T*constant
V/T = constant
Based on this, the correct choice is:
</span><span>a) V/T</span>
I believe the answer is C, 3
