Answer:
Explanation:
a ) y = A sin(B) ; here B is the phase of the wave which moves so that it remains constant
ωt - kx = constant
differentiating on both sides
ωdt - kdx =0
ωdt = kdx
dx / dt = ω / k
wave velocity = ω / k
b ) ω = 14.5 rad / s ,
k = 18 rad / m
wave velocity = ω / k
= 14.5 / 18
= .805 m /s
80.5 cm / s
c )
Amplitude = A
= 9.5 m
The higher the voltage, the lower the current. ... The lower current that accompanies high voltage transmission reduces resistance in the conductors as electricity flows along the cables. This means that thin, light-weight wires can be used in long-distance transmission.
Answer:
4. genetics set a range for the level of shyness and environmental influences will interact with that range.
Explanation:
4. genetics set a range for the level of shyness and environmental influences will interact with that range.
Environmental changes determine to which range certain traits work. e.g the eggs hatch but only when certain heat is provided to them. similarly genetics work in all behaviuors but it shows when conditions are most favourable.
Every child is born with an ability to learn but only those learn who are given the environment to do so.
