Answer:

Work done=50J

Heat removed=29J

Now

\\ \sf\longmapsto \Delta E=-50+29

\\ \sf\longmapsto \Delta E=-21J

Hence the internal energy would decrease by 21J

aleksley [76]

Answer:

V ∝ abc

Explanation:

This task is a joint variation task involving only direct proportionality:

Direct variation is one in which two variables are in direct proportionality to each other. This means that as one increases, the other variable also increases and vice - versa.

Joint variation is one in which one variable is dependent on two or more variables and varies directly as each of them.

In this exercise:

If a ∝ b and a ∝ c, then a ∝ bc

Taking the above three proportionalities,

V ∝ a ∝ b ∝ c

V ∝ a ∝ bc

V ∝ abc

"High-intensity" storms produce larger drops that fall faster than those of "low-intensity"storms and therefore have greater ability to destroy and dislodge particles from the soil matrix.
