A student wishes to measure the speed of a toy car at the bottom of an inclined plane. Which information is needed to calculate speed? O A the mass of the car and the height of the inclined plane the friction of the surface of the inclined plane and the mass of the car the length of the inclined plane and the time for the car to descend the inclined plane the length of the car and the time for the car to descend the inclined plane
Answer:
Distance/time
Explanation:
=speed

Dependant: Their heart rate and pulse
Explanation: Control group: is the one that sat in silence
The one that listened to music is the Experimental Group
The independent variable is the thing that they change, the music
And the dependant variable is what is being measured, their pulse and heart rate

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

A habitat that receives little or no precipitation will most likely be suitable for organisms that -
spend most of the day in the sunlight.
are covered in thick fur to keep warm.
store large quantities of water internally.
hibernate for long periods of time.
Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.
What is Precipitation?Any liquid or frozen water that condenses in the atmosphere and falls to the ground is referred to as precipitation. Rain, sleet, and snow are only a few of its various manifestations.
Precipitation is one of the three main processes that make up the global water cycle, together with evaporation and condensation.
Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. The drips hit the ground when they are sufficiently hefty. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations.
Therefore, Sunlight is not always a requirement- but less water = more water that needs stored. Think - succulents, for example. Succulents live in mid - low shade and store water because they live in an environment with little precipitation.
