Work formula:
W = F * d
F 1 = 40 N, d 1 = 6 m;
F 2 = 30 N; d 2 = 6 m.
W ( Cindy ) = 40 * 6 = 240 Nm
W ( Andy ) = 30 * 6 = 180 Nm
The difference of their amounts if work:
240 Nm - 180 Nm = 60 nm
hope it helps!
#1
For closed pipe the fundamental frequency will be given as




#2
For open pipe the wavelength for Nth harmonic will be given as


#3
for a closed pipe the frequency is given as

here for third harmonic n = 3

now plug in all values



#10
since in the given figure there are three complete loops
so in this case the <em>number of harmonics are THREE</em>

Answer:
0.275 m/s²
Explanation:
The acceleration of an object is defined as the change in velocity over the change in time.
We are given the initial velocity, 0.75 m/s. The final velocity of the user in question is 3.5 m/s.
The time it takes for us to catch the train is 10 seconds. Using these variables, let's substitute into our equation.
- a = (3.5 - 0.75)/10
- a = 2.75/10
- a = 0.275 m/s²
Our acceleration over that time was 0.275 m/s² in order to catch the train.
