Answer:
a) humidity
Explanation:
asia is known for miserable humid weather
Answer:
0.87 m
70.6 Hz
Explanation:
= length of the rope = 1.30 m
= order of the harmonic = 3
= Wavelength
Wavelength is given as
= 0.87 m
= Speed of transverse wave = 61.4 m/s
= frequency of the third harmonic
frequency is given as
= 70.6 Hz
This is how far I got:
put equation 3. into 1. together with h = 5:
4.
when I double m₁ the ratio becomes:
5.
when I put these to ratios back into equation nr 1 and nr2, I find the ratio:
and new v₁ = 2.95
I'm not sure this is correct.
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
The forces are the same however at the moment to determinate the acceleration
are constant because they make the same motion however the difference of mass make the acceleration difference
Answer:
LHS=RHS=[L]
Explanation:
Given mathematical expression:
where: dimension:
s = displacement length
u = initial velocity
t = time
a = acceleration
now using dimensional analysis:
we know that the ratio and constants have no dimension.
as we know that only similar dimensions can be added or subtracted therefore we get a correct conclusion.
<em>However we can deduce the operators between the equations and can neither check for the validity of the constants. We can only check for the dimension of the terms involved.</em>
