Answer:
A The shorter the wavelength the higher the frequency the longer the lower, hope this helps, thanks.
Answer:
V at C is 3.6 m/s
Explanation:
At A kinetic energy is zero and potential energy=mgh=0.5*9.81*0.6=2.943 J
By conservation of energy.
KE+PE=Constant
At C PE=0.6 J
the KE=2.943-0.6=2.343 J
KE=0.5*m*v^2
v=√[KE/(0.5*m)]=3.06 m/s
Answer:
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Explanation:
Answer:
a) 100Hz
b) opened at both ends
c) 1.72m
Explanation:
Let fun be the nth Harmonic frequency organ. If pipe is opened at both ends.
L= length of pipe
Fyn =(n/x)
550hz= (n/2L)v 1
650hz=(n+1/2L)×v 2
Comparing 1 and 2
650hz= nv/2L + v/2L
550= 343/2L
L= 550×2/343 = 1.7m
c) fundamental frequency
Fo= nv/2L = 343/(2×1.7) = 100Hz
4 to 1
Explanation If you look at it as a fraction 160/40 and you reduce it down as far as you can you get 4/1
