Suppose we have two rock samples, A and B. If rock A was subject to both physical and chemical weathering while rock B was subje

hammer [34]

Answer:

Rock A because after physical weather and chemical weathering it more likely for Rock A to experience more chemical weathering.

Explanation: Weathering: This is a geological term used to describe the various processes and Activities involved in the breaking down of rocks either through physical,mechanical,chemical etc actions into smaller particles.

ROCK A WILL HAVE MORE CHEMICAL WEATHERING BECAUSE THE PHYSICAL WEATHERING MUST HAVE BROKEN DOWN THE PARTICLES FOR EASY WATER AND OTHER SUBSTANCE NEEDED FOR EASIER CHEMICAL REACTION OR WEATHERING.

An object on top of a building has a GPE of 23,048j and a mass of 39kg, What is the height of the object

kirill115 [55]

Answer:

<h2>59.1 m</h2>

Explanation:

The height of the object can be found by using the formula

$h = \frac{p}{mg } \\$

where

p is the potential energy

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

$h = \frac{23048}{39 \times 10} = \frac{23048}{390} \\ = 59.0974...$

We have the final answer as

<h3>59.1 m</h3>

Hope this helps you
