An object completes 2500 cycles in 25 s. a. What is the period of its rotation?
b. What is the frequency of its rotation?

a) 0.01s

b) 100Hz

Explanation:

Period is defined as the time taken by a wave to complete 1 oscillation.

Since the object completes 2500 cycles in 25secs, we can write

2500cycles = 25secs

1 cycle = x

Cross multiply

2500x = 25

x = 25/2500

x = 0.01secs

Hence the period of its rotation is 0.01secs

b)  is the reciprocal of the period

Frequency = 1/Period

Frequency = 1/0.01

Frequency = 100Hertz

Hence the frequency of rotation is 100Hz

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!
