El peso de un cuerpo es de 392.2 N ¿Cuál es su masa?
alexandr1967 [171]

Answer:

⇒ To find the mass, we apply the following formula:

                         \boxed{ \boxed{\mathbf{m=\dfrac{w}{g} }}}

<u>Data</u>:

➢  \textrm{Weight(w) = 392.2 Newtons}

➢  \mathrm{Gravity(g) = \ 9,81\ m/s^{2} }

➢  \textrm{Mass(m) =\ ?}

∴ We replace and develop:

\mathrm{m=\dfrac{w}{g} }

\mathrm{Mass=\dfrac{392.2}{9.81} }

\mathrm{Mass =39.9\ kg }

<h2>Body mass is 39.9 kg</h2>

Un automovil de 900 kg toma una curva de radio de 40 m con una rapidez constante de 50 km/h. Cual es la fuerza neta necesaria pa
Llana [10]

Answer:

Fc = 4340,93 Newton

Explanation:

Dados los siguientes datos;

Masa = 900 kg

Velocidad, V = 50 km/h a metros por segundo = (50 * 1000)/(60 * 60) = 50000/3600 = 13,89 m/s

Radio, r = 40 m

Para encontrar la fuerza centrípeta;

Fc = mv² / r

Fc = (900 * 13,89²)/40

Fc = (900 * 192,93)/40

Fc = 173637/40

Fc = 4340,93 Newton

Describe what happens to the energy of a wave if the frequency decreases and the frequency increased
Nata [24]

"As frequency increases, wavelength decreases. Frequency and wavelength are inversely proportional. This basically means that when the wavelength is increased, the frequency decreases and vice versa. Wavelength is described as the distance between a trough to a trough or a crest to a crest."

I'd recommend paraphrasing it tho.

If Mercury, moved two orbital paths closer to the sun: what would be different? List serval differences, ideas.......
elena-14-01-66 [18.8K]
Well first of all, when it comes to orbits of the planets around
the sun, there's no such thing as "orbital paths", in the sense
of definite ("quantized") distances that the planets can occupy
but not in between.  That's the case with the electrons in an atom,
but a planet's orbit can be any old distance from the sun at all. 

If Mercury, or any planet, were somehow moved to an orbit closer
to the sun, then ...

-- its speed in orbit would be greater,

-- the distance around its orbit would be shorter,

-- its orbital period ("year") would be shorter,

-- the temperature everywhere on its surface would be higher,

-- if it has an atmosphere now, then its atmosphere would become
less dense, and might soon disappear entirely,

-- the intensity of x-rays, charged particles, and other forms of
solar radiation arriving at its surface would be greater.
