A STONE IS THROWN VERTICALLY UPWARD WITH THE VELOCITY 25/s HOW LONG DOES IT TAKES TO REACH THE MAXIMUM HEIGHT?

Answers

Answer:

time taken to reach maximum height is 2.548 sec and Maximum height is 31.855 m

Explanation:

Initial velocity U= 25 m/s

at maximum height velocity, V= 0 m/s

Let the time taken to reach maximum height be t and maximum height be H.

V= U-gt

so 25-9.81.t=0

therefore t= 25/9.81  = 2.548 sec

Now,

H= Ut-1/2(gt^2)

 =25x2.548-0.5x9.81x(2.548^2)

 =31.855 m

In two to three sentences, explain what conclusions could be drawn from this information.

Explanation:

It means that out of 20 students, 3 males and 1 female were digital screen addicts because they were getting dangerous amount of blue light. Thus couldn't feel calming sensation that a human feels while seeing blue light. The rest students were getting balanced blue light. So they were getting relaxed feeling while being exposed to blue light.

en and Karen are travelling for the weekend. They both leave from Jen's house and meet at their destination 250 miles away. Jen drives 45mph the whole way. Karen drives 60mph but leaves a half hour after Jen. How long does it take for Karen to catch up with Jen

Answers

Answer:

1 1/2 hours. for Karen to catch Jen.

Explanation:

Karen needs to make up 22.5 km which is the distance Jen travels in 1/2 hour.

The distance where they meet must be equal from the starting point.

Jen

Jen is out 1/2 hour longer.

Let the Karen's time  = t

d = r * t

d = 45 * (t + 1/2 hour)

Karen

d = 60 * t

The distances are equal

so

Meeting time

45*(t + 1/2 hour) = 60 * t

45t + 22.5 = 60t                   Subtract 45t from both sides

22.5 = 15t                              Divide by 15

t = 22.5 / 15

t = 1 1/2 hours = 1.5 hours.

Now you have to interpret the results.

Remember that Jen has travelled 1/2 hour more than Karen

Her time is 2  hours.

Karen's time is 1.5 hours.

Jen travels 2 hours which is 2 * 45 = 90 miles

Karen travels 1 1/2 hours which is 1.5 * 60 = 90 miles

Answers

The term which best describes the repeated arrangement of the same molecule is: D. extended structure.

An atom can be defined as the smallest unit which comprises the matter that forms all chemical elements. Thus, atoms are typically the fundamental building blocks of matter and as such determines (defines) the structure of a chemical element.

what colors are included in our visible spectrum?​

Answers

ALL colors are in the visible spectrum.

"Color" is a word we use to describe light that our eyes can detect.  If the light has a "color", that means we can see it, and somebody gave it a name.  If we can't see it, then we don't have a "color" to describe it.

Every color that has ever been perceived by human eyes is present in the humanly-visible spectrum, except "black".

There are at least hundreds of them. Probably thousands.  Maybe millions.

The Colours that are included in visible spectrum are - 7 Colours namely :

Red Orange yellowgreen blueindigoviolet

Explanation:

when white light passes through a prism , the violet light bends most and the red light bends the least.Dispersion of light is the phenomenon of splitting of white light into its constituent seven colours on passing through a glass prism.The band of seven Colours so obtained is called visible spectrum.

The seven Colours of white light are Violet, indigo , blue, green , yellow, orange and red . It is remembered by the acronym - VIBGYOR.

what occurs at the end of a negative cell if an electric cell is placed in a closed circuit?​

Answers

1. Current means flow of electrons and electrons are negative charged and so are attracted to the positive end of the battery and repelled by the negative end.

2. When battery is connected in a circuit that lets the electron flow through it, they flow from negative to positive.

3. When negative terminal of cell is connected to other negative terminal of the cell in a particular circuit then, current will not flow in circuit as electrons cannot flow from negative to negative terminal.

The acceleration of a particle is given by a = c1 + c2v, where a is in millimeters per second squared, the velocity v is in millimeters per second, and c1 and c2 are constants.
