The gravitational energy of a swimmer on a driving board at different heights is shown in the table below. What is the driver's gravitational energy at 5m high? (A) 5500 J (B) 2750 J (C) 8800 J (D) 3300 J

E = 2750 J at h = 5 m

Explanation:

The gravitational potential energy is given by :

In this case, m is the mass of swimmer is constant at every heights. So,

At h = 1 m, E = 550 J

So, at h = 5 m, gravitational potential energy is given by :

So, the correct option is (B).

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
