Answer:
0.125Hz
Explanation:
The relationship between period and frequency is given by
where f is the period and T is the frequency.
Given that T = 8.00s
The period of a swinging object is the time it takes to make one complete oscillation, it is measured in seconds (s) while the frequency is the number of complete oscillations made per unit time and it is measured in Hertz (Hz). Period and frequency are inverse of each other.

Answer:
qualitative observations.
Explanation:
In a qualitative observation, the data that is dealt with is one that has to do with the sense of touch, sight, smell, taste and also hearing. This type of observation does not have anything to do with measurements that involves numbers. Examples of qualitative observation includes shapes, color, gender, citizenship.
Answer:
36 N
Explanation:
The tension on the string :
T =mv²/r ------where
m= mass of object = 8 kg
v= tangential velocity = 3 m/s
r= length of the string = 2m
T= [ 8 * 3² ] / 2
T= 36 N
