Como surgiu a capoeira?
xz_007 [3.2K]
La capoeira se desarrolló en Brasil, derivada de las tradiciones traídas a través del Océano Atlántico por africanos esclavizados y alimentadas por el ardiente deseo de libertad. Pronto se practicó ampliamente en las plantaciones como un medio para romper los lazos de la esclavitud, tanto física como mentalmente.

A person in bare feet is standing under a tree during a thunderstorm, seeking shelter from the rain. A lightning strike hits the
Anni [7]

Answer:

I=38.181\ A is the current through the body of the man.

E=34.5\ J energy dissipated.

Explanation:

Given:

  • time for which the current lasted, t=43\times 10^{-6}\ s
  • potential difference between the feet, V=21000\ V
  • resistance between the feet, R=550\ \Omega

<u>Now, from the Ohm's law we have:</u>

I=\frac{V}{R}

I=\frac{21000}{550}

I=38.181\ A is the current through the body of the man.

<u>Energy dissipated in the body:</u>

E=I^2.R.t

E=38.181^2\times 550\times 43\times 10^{-6}

E=34.5\ J

What can you infer about the density of two objects if they object remains suspended in the liquid?
ZanzabumX [31]

Answer:

Equal Densities

Explanation:

if the density of the object was greater than that of the liquid, it would sink to the bottom. if the density od the object was lesser than the liquid, it would float :)

HELP PLEASE 
-BARSIC- [3]
Angel !  You have a formula, and you have an example that's
completely worked out.  The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.

I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.

Write the formula on the wall:

                                   °F  =  (9/5) °C  +  32°

A).  Convert 35° C        °F  =  (9/5)(35°) + 32°

(9/5)(35) = 63              °F  =      63°      + 32°

                                     °F  =  95°
____________________________________

B).  Convert 80°F to °C 
                         The formula:    °F  =  (9/5) °C  +  32°

°F = 80                                     80  =  (9/5)°C  +  32

Subtract 32 from each side:      48 = (9/5)°C

Multiply each side by  5 :        240  =  (9) C

Now you take over:
_________________________________________

C).  Convert 15°C to °F.
                         The formula:    °F  =  (9/5) °C  +  32°

°C = 15                                      °F = (9/5) 15° + 32

(9/5) (15) = 27     
                             Go !              °F  =
