What’s the difference between mechanical and chemical weathering
vampirchik [111]

Answer:

Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.

Explanation:

Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals, in just the same proportions as the original rock.

Chemical weathering is the other important type of weathering. Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition Chemical weathering works through chemical reactions that cause changes in the minerals.

A dock worker applies a constant horizontal force of 81.0 N to a block of ice on a smooth horizontal floor. The frictional force
AnnZ [28]

Answer:

The correct answer is:

(a) 84.240 kg

(b) 24.038 m

Explanation:

The given values are:

Force,

F = 81.0 N

Distance,

S = 13.0 m

Time,

t = 5.20 s

As we know,

The acceleration of mass will be:

⇒  a=\frac{2S}{t^2}

On substituting the given values, we get

⇒     =\frac{2\times 13.0}{(5.20)^2}

⇒     =\frac{26}{27.04}

⇒     =0.961538 \ m/s^2

(a)

The mass of the block will be:

⇒  m=\frac{F}{a}

On substituting the given values, we get

⇒       =\frac{81.0}{0.961538}

⇒       =84.240 \ kg

(b)

The final velocity after a given time i.e.,

t = 5.00 s

⇒  v=at

On substituting the values, we get

⇒     =0.961538\times 5.00

⇒     =4.8076 \ m/s

In time, t = 5.00 s

The distance moved by the block will be:

⇒  d=vt

On putting the values, we get

⇒     =4.8076\times 5.00

⇒     =24.038 \ m
