2) Stored mechanical energy is converted to mechanical energy.
3) Stored chemical energy is converted to thermal energy.
4) Stored chemical energy is converted to mechanical energy.

Answers

Answer:

  4) Stored chemical energy is converted to mechanical energy.

Step-by-step explanation:

The battery represents energy stored in the form of chemical compounds. The motion represents mechanical energy. The transfer occurs between these forms of energy.

  4) Stored chemical energy is converted to mechanical energy.

Se sabe que los catetos de un triangulo rectangulo miden 0,4 cm y 0,3 cm. Micaela dice que su perimetro es igual a 1,2 cm ¿Sera cierto? De no ser asi , determina el valor del perimetro correcto

Answers

Answer:

El perímetro es de 1.2 cm

Step-by-step explanation:

La formula del perímetro de un triángulo rectángulo es:

p = cateto1 + cateto2 + hipotenusa

Para determinar el valor de la hipotenusa usamos el Teorema de Pitágoras:

hipotenusa² = cateto1² + cateto2²

hipotenusa² = 0.4² + 0.3²

hipotenusa² = 0.16 + 0.09

hipotenusa² = 0.25

√hipotenusa² = √0.25

hipotenusa = 0.5

entonces, el perímetro es:

p = 0.4 + 0.3 + 0.5

p = 1.2cm

por tanto

Micaela tiene razón, el perímetro es de:

1.2 cm

-1/2x+3=-x+7 what does x equal

Answers

Answer:

x = 8

Step-by-step explanation:

-1/2x+3=-x+7

Add x to each side

-1/2x+x+3=-x+x+7

1/2x +3 = 7

Subtract 3 from each side

1/2x +3-3 = 7-3

1/2x = 4

Multiply each side by 2

1/2x *2 = 4*2

x = 8

Step-by-step explanation:[tex]x^{2}[/tex]

6([tex]x[/tex]-3)([tex]x^{2}[/tex]+4)([tex]x[/tex]+1) = 0

6([tex]x[/tex]-3)([tex]x[/tex]+2)([tex]x[/tex]-2)([tex]x[/tex]+1) = 0

Using the fact that ([tex]x^{2}[/tex]+4) = ([tex]x[/tex]-2)([tex]x[/tex]+2) - known as the difference of two squares rule

Thus solve by inserting values of [tex]x[/tex] that will result in the equation equating to 0.

three friends all live on the same street that runs west to east. Beth lives 6 blocks from Al. Carol lives 2 blocks from Beth. If the street is represented by a number line and Al’s house is located at 0, what are the possible locations for Carol’s house?

Answers

Answer:2, -2, 6 or -6

Step-by-step explanation:

Given,

The location of Ann's house in the number line = 0,

∵ Ben lives 4 blocks from Ann.

So, the possible location of Ben's house =  4 ( right of ann's house ) or - 4 ( left of ann's house )

Now, Carl lives 2 blocks from Ben,

So, the possible location of Carl's house

Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )

Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )

14. The diameter of carbon atom is about 3.4 x 10-7 millimeter. Is it more appropriate to report the diameter of carbon atom
as 3.4 x 10-7 millimeter or 3.4 x 10-13 kilometer? Explain your reasoning.
I

Answers

Answer:

  it depends

Step-by-step explanation:

I like to choose the units to be compatible with the use of the number.

In Engineering, we often choose units so the number itself is between 1 and 1000. Here, that means 3.4×10^-7 mm would be better expressed as 3.4 angstroms or 340 pm (picometers). (The purpose of SI prefixes is to facilitate this way of representing metric measures.)

If you're comparing the length to something measured in km, then the representation as 3.4×10^-13 km might be the most useful

If you're comparing the distance to something measured in mm, then 3.4×10^-7 mm would be more appropriate than 3.4×10^-13 km.

Ann Clair and josh collect sticker one week Ann collects 7 more sticker then josh josh collect twice as many stickers as Claire. If they collect a total of 157 stickers how many sticker did each collect

Answers

Answer:

Ann: 67Clair: 30Josh: 60

Step-by-step explanation:

If we let A, C, and J represent the number of stickers collected by Ann, Clair, and Josh. respectively, then we have the relations ...

  A = J +7

  J = 2C

  A + C + J = 157

__

Substituting the first equation into the last, we have ...

  J +7 + C + J = 157

  C +2J = 150 . . . . . . . collect terms, subtract 7

Substituting the second equation into this one, we have ...

  C +2(2C) = 150

  C = 150/5 = 30 . . . .  divide by the coefficient of C

  J = 2·30 = 60

  A = 60 +7 = 67

Ann collected 67 stickers, Clair collected 30, and Josh collected 60 stickers.

Answer:

Ann has 67

Josh has 60

Claire has 30
