Answer: dry ice

Explanation:

Sublimation process where solid state changes to gaseous state by escaping liquid state.

$CO_2(s)\rightarrow CO_2(g)$

Deposition process where gaseous state changes to solid state by escaping liquid state.

$CO_2(g)\rightarrow CO_2(s)$

Solid carbon dioxide is also called as dry ice due to its similarity in appearance to ice and dry because the liquid state is not encountered.

This is a group of elements with few valence electrons that conducts heat and electricity.

k0ka [10]

Answer:

Metals

Explanation:

The group of elements with few valence electrons that conducts heat and electricity is known metals. Metals are good conductors of heat and electricity. The outer electrons in metals are loosely bound to the atom and are thus able to freely move around and conduct electricity and heat.

PlS help <br>I really need help.<br>very urgent<br><br>PLS help

Draw a freebody diagram, it will explain it really well

the boat is floating on top of the water, which means that the net acceleration in the y direction must be zero

the boat is not sinking (dominant downwards acceleration/force)
the boat is not flying (dominant upward acceleration/force)

that measn
$F_{net_y} =0$

now, if you drew the FBD, you only have 2 forces acting on the boat.
the upward bouyancy force on the boat and the downward force due to weight

$F_{net_y}= F_{bouyancy} - F_{weight}$

since the net force is equal to zero

$F_{bouyancy} - F_{weight} = 0$

and thus

$F_{bouyancy} = F_{weight}$

The speed of light is about 3.00 × 10 meters per second. What is the frequency of green light that has a wavelength about 500 na

RideAnS [48]

Answer:

The frequency of the green light is $6x10^{14}Hz$

Explanation:

The visible region is part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of $3.00x10^{8}m/s$ in the vacuum.

Green light is part of the visible region. Therefore, the frequency can be determined by the following equation:

$c = \lambda \cdot \nu$ (1)

Where c is the speed of light, $\lambda$ is the wavelength and $\nu$ is the frequency.

Notice that since it is electromagnetic radiation, equation 1 can be used. Remember that light propagates in the form of an electromagnetic wave (that is a magnetic field perpendicular to an electric field).

Then, $\nu$ can be isolated from equation 1

$\nu = \frac{c}{\lambda}$ (2)
