How is the life cycle of a star similar to that of a human?

QveST [7]

Stars have a life cycle, just like people: they are born, grow, change over time, and eventually grow old and die. Most stars change in size, color, and class at least once in their lifetime.

What is the most likely result of the pollution of a fresh water resource?

Troyanec [42]

Answer:

Loss of biodiversity in the wetlands.

Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.

Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.

A compressor takes 0.50 m3 of a gas at 33°C and 760 mmHg and compresses it to 0.10 m3, cooling it to -55°C at the same time. Wha

vodomira [7]

Answer is C.

Converting temperatures to degrees K: 33 degrees C = 306 K and -55 = 218 degrees K.

By the ideal gas law:-

760 * 0.50 / 306 = P * 0.10 / 218

P = 760 * 0.50 * 218 / 306 * 0.10

= 2700 mm Hg answer

In 3–5 sentences, explain why electrical wires are often constructed from metal coated with rubber, and how that is similar to m

stich3 [128]

Answer:

Covering electrical wires in plastic guarantees that the electrons flowing through the wires will not flow through your body when the wire is touched.

Explanation:

"The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors."
