Answer:
A) because wave speed remains constant.
Explanation:
The wave speed of a wave in a medium depends on the nature of the medium.
For transverse waves in a string given by,
, T = tension , m = linear density
For longitudinal waves in a solid,
, ξ = modulus of elasticity, ρ = density
Like wise for different media, different properties and parameters govern the speed of waves moving through them.
It is important to mind in v = fλ ,f or λ does not influence on speed of wave in a medium but shows how f and λ varies as a wave propagate in a medium(/media).
A the entropy of the reaction I think ion know if that’s correct
Answer:
A the type of dog food because it was different and every other thing was the same.
Answer:
d = V/E
Explanation:
From the definition, we can say that the electric field strength between the plates of a parallel plate capacitor is
E = v/d
where
E = electric field strength
V = potential difference
d = distance between the plates
On rearranging the equation and making d subject of the formula, we have
d = V/E
From the question, we're given that
V = 112 V
E = 1.12 kV/cm converting to V/m, we have 110000 V/cm
d = 112 / 110000
d = 0.00102 m
d = 1.02*10^-3 m
