Answer:

a. endothermic

Explanation:

The reaction shown is an endothermic reaction. In such reaction, they require an input of energy.

  • Endothermic changes involves absorption of heat from the surrounding.
  • The surrounding becomes colder at the end of the reaction.
  • When heat is on the reactant side, it suggests a reaction that requires a considerable input of energy.

Match each characteristic with the type of wave it corresponds to. Longitudinal waves Transverse waves The direction the wave tr
zubka84 [21]

Answer:The direction the wave travels is parallel to the displacement of the medium.LW.

Electromagnetic waves are an example of this type of wave. TW

Sound waves are an example of this type of wave.LW

Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW

If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW

The direction the wave travels is perpendicular to the displacement of the medium.TW

Explanación:

the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.

In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.

What is the amount of heat, in Sl units, necessary to melt 1 lb of ice?
likoan [24]

Answer:

Heat required to melt 1 lb of ice is 151.469 KJ

Explanation:

We have given mass of ice = 1 lb

We know that 1 lb = 0.4535 kg

Latent heat of fusion for ice =334 KJ/kg

Amount if heat for fusion of ice is given by

Q=mL, here m is mass of ice and L is latent heat of fusion

So heat Q=mL=0.4535\times 334=151.469kj

So heat required to melt 1 lb of ice is equal to 151.469 KJ

The weight of an object on a planet depends not only on its mass but also on its distance from the planets center this table lis
Korvikt [17]

You just pointed out that the gravitational force also depends
on the distance from the planet's center. The radius of Uranus
is about 4 times the Earth's radius.  That fact alone means that
the gravitational force on the surface is 1/4² = 1/16 its value on
Earth's surface.  So increasing the planet's mass by a factor of
14 doesn't compensate for the 1/16 reduction, and the gravitational
force on Uranus is less than on Earth.
