Hey there,
Density = Mass/Valume
D= 3.1/0.35
D= 8.86 g/cm3
Answer:
In a global convection cell less –dense air at the equator rises and flows towards the poles. And from pole, the dense air sinks down and flows back towards the equator.... This movement of air is also supported by the Earth's rotation known as Coriolis Effect.
Average speed = total distance / time ⇒ total distance = average speed * time
Average speed = 270 km / p hours
distance = d
hours = x
d = 270/p * x
Answer:
D
Explanation:
Option A, B and C are true about energy conversion devices, only option D is NOT true about energy conversion devices.
