It is a parabola, or a curve. Hope this helps!
Answer: 324m
Explanation:
Speed (v) = 2.7m/s
t= 2 min
Convert time in minutes to seconds
t = 2 x 60 = 120s
Distance (s) = ?
Speed(v)= distance(s)/time(t)
v = s / t
Distance(s) = speed x time
Distance(s) = 2.7 x 120
Distance(s) = 324m
The distance is 324m
The following apply:
Sound is a LONGITUDINAL wave.
Sound is a PRESSURE wave.
Longitudinal waves are waves in which the displacement of the medium is in the same direction as or opposite direction to the direction of wave propagation. An example of longitudinal wave is sound wave. Sound wave is also considered as a pressure wave as the result of the presence of repeating patterns of high and low pressure regions moving through a medium.
Answer:
Inductance of a coil(L) = 0.44 H (Approx)
Explanation:
Given:
coil produces emf = 2.40 V
Old current = -27 mA
New current = 33 mA
Time taken = 11 mS
Find:
Inductance of a coil(L)
Computation:
Inductance of a coil(L) = -emf / [Δi / Δt]
Inductance of a coil(L) = -2.4 / [(-33 - 27) / 11]
Inductance of a coil(L) = -2.4 / [-5.4545]
Inductance of a coil(L) = 0.44 H (Approx)
