Speed is the rate of change <span>of distance.</span>
Answer:
a coil rotating in a magnetic field to change its flux
To find ohms or R is R=V/I
I=RxV
V=I/R
I is the amperage and V is the Voltage.
I hope this helped.
Answer:
714s
Explanation:
t=H/v=500000m/700m/s=714s
Answer:
i) b. 14.3 Hz
ii) d. 0.4625 m/s
Explanation:
f = c / λ
f = frequency
c = speed
λ = wavelength
first question:
the given values,
λ = 2.17 m
c = 31 m/s
f = c / λ
f = 31 / 2.17
f = 14.28
∴ f = 14.3 Hz
second question:
given,
λ = 0.25 m
f = 1.85 Hz
f = c / λ
rearranging,
c = f × λ
c = 1.85 × 0.25
c = 0.4625
∴ c = 0.4625 m/s
