Potential energy<span> is the </span>energy<span> that is stored in an object due to its position relative to some zero position. It is calculated by the expression as follows:
PE = mgh
PE = 25 (9.8) (3)
PE = 735 J
Hope this answers the question. Have a nice day.</span>
The correct answer is a rodent that sleeps underground during day
A desert rodent such as kangaroo rat well adapted to live in dessert. It can survive without drinking water. Rodents make underground burrows at the base of shrub or small bush. It spends most of its day sleeping in the burrow underground to avoid intense heat and comes out to feed at night when temperature falls and desert becomes cooler.
Wind ,ice,and water eroded it over years
The appropriate answer is c. the solid phase, liquid phase and gas phase of a substance. A phase diagram is used to represent the phase or physical state of a substance at a given temperature or pressure. Pressure is represented on the y axis while temperature is represented on the x axis. Phase diagrams are used in areas such as Physics, Chemistry, Engineering, Mineralogy and Material Science.
