Answer:
Period = 6 seconds.
Explanation:
Given the following data;
Number of oscillation, n = 10
Time = 1 minute to seconds = 60 seconds
To find the period;
A period is the number of revolutions in a minute.
Substituting into the equation, we have;
Period = 6 seconds.
ive been doing this type of stuff in my class.
so to find this you need to first:
multiply 40 * 2
and multiply 60 * 3
= 80
= 180
add 180 + 80 = 260
add the time together so 2 + 3 is 5
divide 260 / 5 = with an answer of 52km/h
i hope this helps, if incorrect or mis proper answer let me know :)

Answer:
Density of jacket will be 
Explanation:
We know that weight of water displaced= buoyant force=weight of man
Now volume of water displaced 
Density of water 
So weight of water displaced 
So weight of jacket = 98-75 = 23 kg
We have given volume of the jacket = 
So density of jacket
