All follow an elliptical path that has two foci, rather than a circular path.
Kepler found paths are elliptical, not circular
Answer:
L = 3.51
Explanation:
Pendulum equation is T = 2pi
T = 1.5 and we are solving for L
1.5=2
square both sides to get 2.25 = 2
multiply both sides by 9.81 then divide by 2 and 3.14 as a substitue for pi. The answer should be about 3.51 in length
L = 3.51

Emotional stimuli is the answer to your question.
Answer:
what is your question?..... .
Your answer is 5000 J
when W(work) = F X when F= the force and X= the displacment
and F(g) = M a(g) when M= mass and a = the acceleration and in our question
, the force is the gravitational force and a= 9.8 m/S2 we can assume as 10 m/s2
and when we have M= 50 Kg
so by substitution:
F= 50 x 10 = 500 N
and by substitution in work equation: when x = 10 m
∴ W = 500 x 10 = 5000 j
