Answer:
The woman's average velocity during the trip is 36.2 miles/hour.
Explanation:
Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.
i.e velocity = 
From the given question,
Displacement = 
= 
= 
= 425
The displacement of woman is 425 miles.
velocity = 
= 36.1702 miles/hour
The woman's average velocity during the trip is 36.2 miles/hour.
Distance and time, distance because that's how far and time because that's how long
Answer:
<h2> $1.50</h2>
Explanation:
Given data
power P= 2 kW
time t= 15 min to hours = 15/60= 1/4 h
cost of power consumption per kWh= 10 cent = $0.1
We are expected to compute the cost of operating the heater for 30 days
but let us computer the energy consumption for one day
Energy of heater for one day= 2* 1/4 = 0.5 kWh
the cost of operating the heater for 30 days= 0.5*0.1*30= $1.50
<u><em>Hence it will cost $1.50 for 30 days operation</em></u>

Answer:
As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.
