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
<h3>
Answer: 7.74 newtons</h3>
========================================
Steps Shown:
Work = Force*Displacement
Power = Work/Time
Power = (Force*Displacement)/Time
900 W = (F*1000 m)/(8.6 sec)
900 = (F*1000)/8.6
900*8.6 = 1000F
7740 = 1000F
1000F = 7740
F = 7740/1000
F = 7.74 newtons
The Answer is D
Because you add all of them to equal 9 atoms
The Earth gets hotter as one travels towards the core, known as the geothermal gradient. The geothermal gradient is the amount that the Earth's temperature increases with depth. ... On average, the temperature increases by about 25°C for every kilometer of depth.
