Answer:
A velocity-time graph shows how velocity changes over time. The sprinter's velocity increases for the first 4 seconds of the race, it remains constant for the next 3 seconds, and it decreases during the last 3 seconds after she crosses the finish line.
Answer:Existen diversos tipos de energía: mecánica, sonora, luminosa, calorífica, eléctrica, química y nuclear. ... Algunas de las propiedades de la energía son que se transfiere de unos cuerpos a otros, se almacena, se transporta y se transforma de unos tipos en otros.
Explanation:
The theory about global warming will be most strongly affected by scientific studies that reveal how the earth’s temperature has fluctuated in the past. The answer is letter C. According to NASA, carbon dioxide levels have increase to
nearly 38 percent as of 2009 due to the burning of fossil fuels, cutting down
carbon-absorbing forests.

B. condenses is the answer
ANSER TO #11 Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries.
As the plates move away from the spreading centers, they cool, and the higher density basalt rocks that make up ocean crust get consumed at the ocean trenches/subduction zones. The crust is recycled back into the aesthenosphere.Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere.
The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km. It contrasts with the more rigid lithosphere, the outer shell of the Earth (0 ~ 70 km) that contains the continental crust (made up of less dense granitic rocks) and the oceanic crust (more dense basaltic rocks) that are broken up into more than a dozen rigid plates.
