Chemistry

Answer:

(a) A sled sliding down a hill has more kinetic than a sled resting at the top of the hill

(b) water falling over the dam has more kinetic than water above a dam

Explanation:

Kinetic energy is a type of energy that is related to the movement of bodies. The result of kinetic energy is intrinsically linked to the mass value of the object and its velocity of movement.

In short, kinetic energy is generated through movement. For this reason, we can prove that a sled down a hill has more kinetics than a sled resting on the top of the hill just as the water falling on the dam has more kinetics than the water above the dam.

Explanation:

Kinetic energy is defined as the energy obtained by an object due to its motion. Whereas energy obtained by an object due to its position is known as potential energy.

(a)   When a sled is resting at the top of a hill then it means the sled in not moving. Hence, then it has only potential energy. But when a sled sliding down the hill  then it is moving from its initial position.

Hence, when a sled is sliding down the hill then it has higher kinetic energy.

(b)    When water is above the dam then it only has potential energy but when the water falls over the dam then it has higher kinetic energy.

Which of the following sites has volcanoes related to subduction? A is on an island arc, B is in the Andes, C is near Hawaii, D
scoray [572]

Answer:

A is on an island arc,

B is in the Andes

Explanation:

The subduction region is referred to as the subduction zone. When a plate slips underneath another, it forms a trench. Earthquakes resulting from the plate panelling often result in magma spilling across the underwater volcano trench. Island arcs are vast chains of active volcanoes with strong seismicity located along the converging tectonic plate borders. Much of the islands arcs emerge from the oceanic crust and also have originated from fall of the lithosphere into the mantle across the subduction zone. In the Andes mountain range, Under the South American plate the Nazca plate is subducting.

Which compound is a saturated hydrocarbon?
mojhsa [17]
<span>Saturated hydrocarbons are organic compounds that contain only single bonds between the carbon atoms. They are known to be the simplest organic compounds. They are termed as such because they are saturated with water. Examples are the alkanes (ethane, methane, propane, butane, etc.).</span>

Calculate the number of joules needed to change 20.0 g of ice at 0.00 °C to liquid water at 42.8 °C
tigry1 [53]

Answer:

7509.6j

Explanation:

I asked if the temperature of the ice but since it doesn't that means the temperature of the ice is at 0°c and latent heat of fusion [ML] will take place when it changes to water at 0°c also, then the temperature of the water rises to 10°c MCΘ will be used.

Now in the application, using the formula;

mL+MCΘ

Where;

m=20    L=334     M=4.148    Θ=10

Inputting the values we should have;

334×20+4.148×20×10

6680+829.6

7509.6j

What is the process where frost forms​
Alex17521 [72]
Answer: Sublimation

Explanation:
Frost forms when an outside surface cools past the dew point. The dew point is the point where the air gets so cold, the water vapor in the atmosphere turns into liquid. As cool air collects in valleys, frost forms. Frost usually forms at night, when the air temperature is cooler.

I hope this helped! :)

What should i do if there is more than 1 curve on a graph
Elanso [62]

Answer:

Image result for what should i do if there is more than 1 curve on a graph

In a multiple line graph, there are two or more lines in the graph connecting two or more sets of data points. The independent variable is listed along the horizontal, or x, axis and the quantity or value of the data is listed along the vertical, or y, axis. Lastly, the legend, or key, states what each line represents.
