Which statement is true about a falling object? (Assume no

Physics

5 0

I would say the answer is 3 because by falling technically the ball would be kind of moving in the air. Plus potential energy is when for example a soccer ball isnt moving

As a transverse wave travels through a rope from left to right, the parts of the rope _______.
kupik [55]
<h3><u>Answer;</u></h3>

Are moving up and down.

As a transverse wave travels through a rope from left to right, the parts of the rope <u>are moving up and down</u>.

<h3><u>Explanation;</u></h3>
  • Transverse waves occur when a disturbance causes oscillations perpendicular to the propagation, that is the direction of energy transfer.
  • <em><u>Particles of the medium move perpendicular to the direction the transverse wave itself is moving.  For example, if the wave is moving to the right, the particles of the medium are moving up and down.</u></em>
  • <em><u>Therefore, as a transverse wave travels through a rope from left to right, the parts of the rope are moving up and down.</u></em>

Simple diffusion and facilitated diffusion are related in that both
kaheart [24]

Answer:

allow the downward movement of the concentration gradient by passive transport

Explanation:

Passive transport is a process of substance transport, which is carried out spontaneously, without energy expenditure and in favor of the concentration gradient, that is, from a medium where the molecules are more concentrated towards a medium where their concentration is lower.

Three types of passive transport are distinguished: osmosis, simple diffusion and facilitated diffusion

<u>Simple diffusion</u>

It is the passage, through the plasma membrane, of small molecules without charge soluble in the lipid bilayer, such as some gases (oxygen and carbon dioxide). For a molecule to diffuse through the membrane it is necessary that there is a difference in concentration between the external and the internal environment.

<u>Diffusion facilitated </u>

There are molecules such as amino acids, glucose and small ions that, due to their chemical and size characteristics, cannot diffuse through the lipid bilayer and require transport proteins for diffusion.

The transport proteins are immersed in the plasma membrane and can be of two types: protein channels, formed by proteins that generate a channel in the membrane, and permeases, which are proteins that, when joined to the molecule to be transported, change their shape by carrying them into the cell.

16 grams of ice at –32°C is to be changed to steam at 172°C. The entire process requires _____ cal. Round your answer to the nea
inysia [295]

Answer:12,352 cal

Explanation:

Given

to change 16 gm ice at -32^{\circ}C to 172^{\circ}C

First we need to take ice to 0^{\circ}Cthen change its state to water and then raises water temperature from 0 to 100^{\circ}C .

After it change water phase to steam and then raise its temperature to 172^{\circ}C

heat required(Q)=16\times 0.5\times \left ( 0+32\right )+16\times 80+16\times 1\times \left ( 100-0\right )+16\times 540+16\times 0.5\times \left ( 172-100\right )

Q=12,352 cal
