Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous plan

Elan Coil [88]

Answer:

Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous planet increases linearly with the height of the atmosphere as measured from the top of a visible boundary layer, defined as 0 kilometers in altitude. The instruments on board can withstand a temperature of 601 K. At what altitude will the probe's instruments fail? A. 50 kilometers B. 80 kilometers C. 83 kilometers D. 100 kilometers E. 111 kilometers

Explanation:

A. 50 kilometers

Which of the following is a definition of glass transition temperature?

aleksandr82 [10.1K]

Answer:

c. The temperature at which a glass transforms from a solid to liquid.

Explanation:

The glass transition temperature is said to be a temperature range when a polymer structure transition from a glass or hardy(solid) material to a rubber like or viscous liquid material.

The glass transition temperature is an important property that is critical in product design.

How does the cell membrane work to protect the cell?

LenKa [72]

It forms a protective and adaptive barrier around a cell and this keeps various bacterial and viral intruders out. They also help in keeping cell systems inside the cell. The shell absorbs viruses and bacteria for nutrients when they do not have a certain strand to get inside the cell or trick it otherwise. Hope this helped!

Pls answer I will make brainlist and 20 point

Vladimir [108]

Answer:

Reflection:

The phenomenon of a propagating wave (light or sound) being thrown back from a surface

Sentence: Your reflection is what you see in the mirror. Other things that bounce back at you are also reflections — light waves, sound waves, even your thoughts.

Refraction:

Definition: The change in direction of a propagating wave (light or sound) when passing from one medium to another

Sentence: Refraction is the bending of light or sound as it passes through something like a wall (sound) or a window (light).

Diffraction:

Definition: When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands

Sentence: Diffraction is the process of light bending around an obstacle or spreading out after it moves through a small space. If you study physics, you'll learn about the diffraction of light waves.

Absorption:

Definition: (chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid

Sentence: Absorption describes the process of absorbing or soaking up something: Sponges are good at water absorption; dark colors are better for heat absorption.

Interference:

Definition: The act of hindering or obstructing or impeding

Sentence: Interference is something that is in your way. If the sound of your sister's band practicing keeps you from getting your homework done, that’s interference.

Standing wave:

Definition: A wave (as a sound wave in a chamber or an electromagnetic wave in a transmission line) in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time

Sentence: A bubble, trapped and held in a fixed position by an acoustic standing wave, begins to move erratically if a threshold wave amplitude is exceeded. The longitudinal standing wave is synchronously forced and resonated while the cross-wave is not resonant and is of higher order in amplitude.

Resonance:

Definition: Having the character of a loud deep sound; the quality of being resonant

Sentence: If you have a loud, deep voice, then your voice has resonance, and if your words are powerful and meaningful, then your words have resonance, too. Something with resonance has a deep tone or a powerful lasting effect.

I hope this helps! :)
