Answer:
The average speed is 8.0 km/h
Explanation:
We use the data for the return journey to calculate the distance travelled using the constant velocity equation:
s = v t =6*4=24km
Note I didn't change any units so the answer comes out in kilometres.
Now use the distance and time taken to travel to Guam to find the average speed:
v=st=24/3=8.0km/h
Answer:
Tech A is right.
Explanation:
Its the ability of quartz crystal that if we apply a mechanical stress on them by an applied force then they can produce the electricity or voltage. This phenomenon of producing electricity by squeezing a crystal is termed as piezoelectricity or a piezoelectric effect.
<span>The outermost energy level of an element are called the valence shell, that holds the valence electrons. they consist of the highest energy level. In aluminum, the valence electrons are 3. </span>
<h2>
Answer:</h2>
The distance will be 1800 m
<h2>
Explanation</h2>
As in question
Time = 15 min
Time = 15 x 60 sec = 900 sec
Speed = 2 m/s
We know that



So, the answer is 1800 m
