Answer: the speedometer indicates the speed of a vehicle.
Answer:
The Frequency of the wave is 0.2Hertz
The period is 2seconds
Explanation:
We are asked to find the frequency and period
Frequency is the number of oscillations completed in one seconds
If five waves were made from the same source in 10 seconds, hence;
Frequency = number of oscillation/Time
Frequency = 5/10
Frequency = 0.5Hertz
Next is to get the period
Period = 1/Frequency
Period = 1/0.5
Period = 2seconds
Answer: symbol: R; unit: O
Explanation:
The total resistance of a section of wire can be calculated using the equation pL/a, where “p” represents the resistivity of the material, “L” represents the length, and “a” represents the cross-sectional area. For this problem, simply substitute and simplify
Rwire = pL/a
= (2.82x10^-8)(14,000 m)/(5.9x10^-4)
= 0.6692 ohms
The resistance of this wire under these conditions would be approximately 0.67 ohms.
Hope this helps!
