The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the lithosphere are still considered elastic, they are not viscous
The molecular geometry of both F2 and HF is linear.There are only two atoms which are covalently bonded and thus, the bonding scheme with the atoms looks like this;
F --- F
H---F
So, both are linear.
Answer:
To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.
From the definition of acceleration,
a = (velocity change)/(time required)
In this case you know that a = 5.0 m/s^2, so
time = (10.0 m/s)/(5.0 m/s^2)
= 2.0 seconds
Answer:
36°C
Explanation:
Heat gained by the cold water = heat lost by the warm water
mCΔT = mCΔT
(1000 g) (4.184 J/g/K) (T − 20°C) = (4000 g) (4.184 J/g/K) (40°C − T)
1000 (T − 20°C) = 4000 (40°C − T)
T − 20°C = 4 (40°C − T)
T − 20°C = 160°C − 4T
5T = 180°C
T = 36°C
