Questions that can be answered by doing the experiment and making observations scientifically:

1).  How long will it take to perform the complete experiment ?

2). Will it be daytime or night-time when the experiment begins ?

3). What will be the range of outdoor temperatures during the experiment ?

4). How many times will progress of the experiment be suspended in order to take phone calls ?

Blizzard [7]

Answer:

0.2 J

Explanation:

The pendulum forms a right triangle, with hypotenuse of 50 cm and base of 30 cm.  The height of this triangle can be found with Pythagorean theorem:

c² = a² + b²

(50 cm)² = a² + (30 cm)²

a = 40 cm

The height of the triangle is 40 cm.  The height of the pendulum when it is at the bottom is 50 cm.  So the end of the pendulum is lifted by 10 cm.  Assuming the mass is concentrated at the end of the pendulum, the potential energy is:

PE = mgh

PE = (0.200 kg) (9.8 N/kg) (0.10 m)

PE = 0.196 J

Rounding to one significant figure, the potential energy is 0.2 J.
