Answer: Calculate the work input in a pulley by using the previous readings in the correct mathematical equation. : Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h).
Explanation:
Mechanical weathering is actually breaking down of rocks into smaller pieces by natural forces. Any weathering processes that can cause the physical breakdown of rocks without any type of change in the chemical composition of rocks, called mechanical weathering.
So, looking at each of the definitions in the options, we can easily choose:
1. Hydration : It's a process of absorbing water by substance.
2. Carbonation: It's a process of Carbon Dioxide dissolving in liquid (mostly water).
3. Oxidation : It's a process of oxygen reacting with some element.
4. <span>Exfoliation: It's a process where the rocks erodes by peeling off in sheets or layer by layer rather than grain by grain.
As you can see the last one </span><span>Exfoliation matches with the definition of mechanical weathering. It's one of its types.</span>
Answer:
mass: The quantity of matter which a body contains, irrespective of its bulk or volume. It is one of four fundamental properties of matter. It is measured in kilograms in the SI system of measurement.
Explanation:

Matter the same thing is gas or come dioxide
Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= ( kg-m/s ) I use the subscript "t" for tennis. Momentum of Soccer ball Ps= 0.43 x 13m/s = ( km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.
