What is the slowest type of mass movement?
LiRa [457]

Answer:

Creep

Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. The only way to detect soil creep is to observe the fences, buildings, and other surface objects that may be in that area. As the loosened soil moves slowly downslope, these objects will move along with the soil.

Q = smT
Effectus [21]

Answer:

The heat required is 1262.91 joules or 1.26 kilojoules.

Explanation:

The quantity of heat (Q) required to raise the temperature of a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of aluminum sample = 33.0g

C = 0.89 J/g℃

Φ = (Final temperature - Initial temperature)

= 68°C - 25°C = 43°C

Then, Q = MCΦ

Q = 33.0g x 0.89 J/g℃ x 43°C

Q = 1262.91 J

Since the heat in joules is 1262.91, obtain heat in kilojoules.

If 1000 joules = 1 kilojoules

1262.91 joules = Z

To get Z, cross multiply

Z x 1000 = 1262.91 x 1

1000Z = 1262.91

Z = 1262.91 / 1000

Z = 1.26291 kilojoules (when placed as 3 significant figures, Z is 1.26 kilojoules)

Thus, the heat required is 1262.91 joules or 1.26 kilojoules.
