Answer:

"What is the best advice a parent can give a child?"

Explanation:

The other answers have one clear response. Ex: Orange popsicles melt faster than grape popsicles. That would be a fact.

But parental advice can vary, depending on your opinion. I may say that all parents must teach their children not to talk to strangers, while someone else may say that parents should advice their kids to treat everyone fairly. Nothing can be proven as the only appropriate response.

Hope this helps!

What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?

OLEGan [10]

This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.

A particle whose speed is 50 m/sec moves along the line from A(2,1) to B (9,25)

WINSTONCH [101]

First, calculate for the distance between the given points A and B by using the equation,

<span> D = sqrt ((x2 – x1)2 + (y2 – y1)2)</span>

Substitute the known values:

<span> D = sqrt((9 – 2)2 + (25 – 1)2)</span>

<span> D = 25 m</span>

I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.

<span> t = (25 m)/ (50 m/s) = 0.5 s</span>

<span>Thus, it will take 0.5s for the particle to complete the route. </span>
