Answer:
B)154 J
Explanation:
Mass of bowling ball=m=6.55kg
Height of bowling ball from ground=h=2.4m
Acceleration due to gravity=
We know that
Potential energy=mgh
Where m=Mass of object
g=Acceleration due to gravity
h=Height of object from ground
Substitute the values then we get
Potential energy=
Hence, the increase in the ball's potential energy=154J
Answer:
The friction of the string and its pivotal anchor point cannot be eliminated. The precise measurement of the length of the pendulum is difficult to take by using meter sticks or rulers. The value of the acceleration due to gravity g in the locality is not constant and must be obtained from reliable sources.
It would be B because it makes science to the topic
