Answer:  

Sand has a strong non-polar covalent connection, that prevents water to break it down.

Explanation:

Sand being composed of quartz and small particulars of minerals can only be dissolved in hot acids, unlike sugar which can easily be broken down by water, due to the large magnetic molecular property of water and the ability to evolve sugar in an Intermolecular manner.

s2008m [1.1K]

There are three things needed to be classified as a planet.

Pluto meets 2 of the 3.

The one it does not meet is it doesn’t “clear the neighborhood” which means a planet needs to be gravitationally dominant over all objects around it. Meaning smaller bodies ( asteroids) would either combine with the larger body making it bigger or pushing them away ( out of their orbit) so they do not collide with the larger body.

Susie rides down and to the right on a slide for a total displacement of -3m at an angle of 45 degrees above the ground. What wa
Svetlanka [38]

Susie's vertical displacement is 2.1 m

Explanation:

In order to solve this problem, we have to resolve the displacement vector along the vertical direction.

The vertical component of a vector is given by:

v_y = v sin \theta

where

v is the magnitude of the vector

\theta is the angle between the direction of the vector and the horizontal

Therefore, the vertical  component of the displacement in this problem is given by

d_y = d sin \theta

where

d = 3 m is the magnitude of the displacement

\theta=45^{\circ} is the angle between the  displacement and the horizontal

Substituting, we find

d_y = (3)(sin 45^{\circ})=2.1 m

What is the proper function of a linkage? *
Kryger [21]

Answer:

a) transferring energy

Explanation:

A linkage is an assembly of parts connected together to control forces and movement. The connections between links are called joints and are used for ensuring movement, pure rotation or sliding.

Linkages provides a means in which kinetic energy is being transferred in different directions within a system. This Linkages can be used to Change force  direction, size of force applied or the motion created by the force.

What device produces light by running an electric current through a gas
Andrej [43]

Answer:

fluorescent bulb

Explanation:

A fluorescent bulb is what produces light.

It produces light by passing electric current through a gas to

A fluorescent lamp, is a low-pressure mercury vapor and a gas-discharge lamp that uses fluorescence to produce visible light. like the ones we see.  An electric current in the gas excites mercury vapor, and that produces a short wave ultraviolet light and well that causes a phosphor coating on the inside of the lamp to glow. i tried making this sound as simple as possible.

i hope this really helps you !! thanks this and mark this as brainliest !!!
