Answer:
Explanation:
The two triangles are similar what is the length of DE
Answer:
Velocity formulae should be used in order to know the answer
Answer:

Explanation:
The period of a simple pendulum is given by:

where
L is the length of the pendulum
g is the acceleration of gravity
From this equation we can write

Taking the square of this equation, we get:

So we see that
is proportional to L and inversely proportional to g. So, we can write:

So the only correct option is
