Answer: b. deposition

Explanation:

Erosion is a phenomenon in which there is movement of rocks, sediment, or soil as a result of human activities or by the force of moving wind.

Deposition is a phenomenon when the movement of the transported materials slow down and are dropped in a new location.

Weathering is a phenomenon in which the rocks are broken by physical or chemical factors.

Compaction is a phenomenon in which there is formation of a solid specimen of defined geometry due to association of particles generally caused by compression.

Mademuasel [1]

Answer:

(a) $a=2m/sec^2$

(b) 5220 j

(d) 3446.66 watt

Explanation:

We have given mass m = 290 kg

Initial velocity u = 0 m/sec

Final velocity v = 6 m/sec

Time t = 3 sec

From first equation of motion

v = u+at

So $a=\frac{v-u}{t}=\frac{6-0}{3}=2m/sec^2$

(a) We know that force is given by

F = ma

So force will be $F=290\times 2=580N$

(b) From second equation of motion we know that

$s=ut+\frac{1}{2}at^2=0\times 3+\frac{1}{2}\times 2\times 3^2=9m$

We know that work done is given by

W = F s = 580×9 =5220 j

We know that power is given as

$P=\frac{W}{t}=\frac{5220}{3}=1740Watt$

(d) Time t = 1.5 sec

So $P=\frac{W}{t}=\frac{5220}{1.5}=3466.66Watt$
