stiv31 [10]

Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.

Explanation:

Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.

Zero acceleration is implied on the bikes and the net force is BALANCED.

When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.

Scrat [10]

Complete question:

The San Marcos salamander, Eurycea nana, is a light reddish-brown

translucent salamander about 2-5 cm in length. E. nana is found only in

Spring Lake and a portion of the San Marcos River.

Which human activity would most likely decrease the ability of the

salamanders to survive?

The addition of a new food source into the river that limits competition for

resources

Tourism that helps fund the educational programs related to river ecosystem

conservation

Public transportation that reduces the number of automobiles that contribute to

pollution runoff into the river

Increasing water consumption that decreases the flow of clean water from the

springs that feed the river

Answer:

Increasing water consumption that decreases the flow of clean water from the springs that feed the river

Explanation:

In this question we are required to state the human activity that may likely cause the reduction in the survival rate of the salamander.

the first three options in the question are not the answer to this question. this is because options 1,2,3 would have positive impacts on the Salamander. these positive impacts would increase the ability of the salamander to survive and not decrease it as the question says.

the correct answer is the last option. that is the 4th option. because it has to do with decreasing the amount of water that flows in to the Salamanders habitat by human activities. if humans increase water consumption, then the flow of clean water would reduce. This would then have a negative effect on the Salamander.

What is the largest suspected environmental problem associated with the burning of fossil fuels? A) global warming B) depletion

zysi [14]

The correct answer is option A

The burning of fossil fuel releases carbon dioxide in the environment. Carbon dioxide is the main green house gas. The green house gases work by trapping the heat that comes inside the earth from the sun.

The carbon dioxide is the green house gas that traps maximum heat coming from the sun. If the carbon dioxide would not have been there then the temperature of the earth would have been very low and the atmosphere would have been colder.

But the global temperature is rising due to lost of carbon dioxide present in the environment as the burning of fossil fuels is increasing day by day.
