<h2>
Answer: 1.25 km</h2>
Explanation:
The velocity 
of a wave is given by:
(1)
Where:
is the wavelength of the wave
is the frequency of the wave. Its unit is Hertz (
)
So, we have to find from equation (1):
(2)
Finally we obtain the wavelength of the earthquake wave:

Answer:
The temperature of the windings are 60.61 °C
Explanation:
Step 1: Data given
Resistance = 50 Ω
Temperature = 20.0 °C
After the motor has run for several hours the resistance rises to 58Ω.
Step 2: Calculate the new temperature
Formula: R = Rref(1 + α(T-Tref))
⇒with α = temperature coëfficiënt of Cupper at 20 °C = 0.00394/°C
⇒with Tref = reference temperature = 20°C
⇒with T = end temperature = TO BE DETERMINED
⇒with R = resistance at end temperature = 58Ω
⇒with Rref = resistance at reference temperature = 50 Ω
==> T = (R/Rref - 1)/α + Tref
T = (58/50) - 1 )/ 0.00394 + 20
T = 60.61 °C
The temperature of the windings are 60.61 °C
There's not enough information in the question to calculate the answer.
Knowing the child's walking speed, we would need to know how often s/he takes a step in order to calculate the length of their legs.
