Making a drawing of the system, we will have two forces which are tension and the weight of the object. Balancing the forces present, we do as follows:
T = W
W = 30 N
Therefore, weight is equal to 30 N. Hope this answers the question. Have a nice day. Feel free to ask more questions.
The average speed is the ratio between the total space and the total time of the motion:

The total space is

while the total time is

So, the average velocity is

We can also rewrite it in m/s. The total space is

, while the time is

, and so
C.) chemical to electrical to light
Answer:
C
Explanation:
Usually when you are at the bottom you are at peak speed. It also shows that Kinetic Energy is the green bar and in picture C the green bar is highest.
