One important relationship between chemical and mechanical weathering is . 1. mechanical weathering forms more brittle materials that are easily broken down by chemical weathering.2. mechanical weathering can produce smaller pieces of rock that have more surface area for chemical weathering to work on. 3. chemical weathering can produce smaller pieces of rock that can then be modified by mechanical weathering 4. chemical weathering can form brittle materials that are easily broken into smaller pieces by mechanical weathering

The metric unit of electrical power is the watt volt ampere ohm

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
