Answer:
Answer choice D!
Explanation:
When it comes to running during a hot day, the human body responds to extensive periods of heat by producing sweat. Sweat is necessary in order of cooling down the body, so that is why I figured it would be that answer. I hope this helped!
Answer:
80.6 N/m
Explanation:
mass (m) = 63 kg
time (s) = 44 s
number of oscillations (n) = 8
stretched length of the cord (L) = 23 m
we can calculate the spring constant of the cord from the formula below
f =
x
...equation 1
where
f = frequency
k = spring constant
m = mass
frequency =
frequency =
= 0.18
now we can input all the required values into the equation 1
0.18 =
x 
0.18 x 2π = 
1.13 = 
= 
k = 63 x 1.28 = 80.6 N/m
its B 0.225kPa using the formula p=f/A then change the pascals into kpa
