1. Momentum (P) is a equal to mass (M) times velocity (V). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (triangleP) over the change in Time (triangleT). And the change in momentum (triangleP) is also equal to the impulse (J)

Typically during thunderstorms most lightning strikes carry a negative electric charge; only a few carry a positive charge. Thun
Ierofanga [76]

Answer:<em> Option (D) is correct.</em>

Explanation:

Considering the hypothesis elaborated in this comprehension, it's given that areas that tend to lie near forest fires usually have extra positive strikes since smoke carries positively charged particles. In rudimentary term, this states that occurrence of positively charged particles will result in extra positive strikes.

Option (D) states that occurrence of extra positive strikes will be there even weeks after the charge of smoke particles have been dissociated.

Therefore this option, most seriously undermines the hypothesis.

12. Why do you think afternoons are much warmer than the mornings or evenings? ​
Darya [45]

Answer:

Afternoons are much warmer than the mornings or evenings is explained below in complete detail.

Explanation:

Because in the afternoon the sun is on the head and the beams of sunshine arrive straight to the earth so we exhibit warmer and in daylight and evening the sun is sparse to the earth so we observe colder than an afternoon. However, in the evening, when the sun is weak, I don't sense or experienced loads of heat and sunburn on body parts that are viewing the sun directly.

mote1985 [20]

Answer:

Read this entry from a blog about service dogs.

Lexie, an eight-month-old black Labrador retriever, is sleeping quietly at my feet. I can’t help but think that her soft, velvety ears and alert brown eyes would make her the perfect “doggie model” for pet magazines and pet store ads. However, Lexie will soon have a much more important job to do. In a few months, she will become the loyal companion and service dog for a young man who has been blind since birth. She will help him board public transportation, such as buses, subways, and trains, and she will help him safely cross busy intersections. Lexie will even help the young man avoid obstacles, such as high curbs and low overhangs. Like all dogs in our organization, Lexie has undergone months of specialized training to help a visually impaired person lead an active and independent life.

What is the secondary purpose of this blog?

to inform readers about seeing-eye dogs

to entertain readers with details about Lexie

to persuade readers to train service dogs

to convince readers to adopt Labrador retrievers
