Hawaiian term for lava that has a rough surface made of broken lava blocks?
A'a' pronounced ah ah
ʻAʻā lava - (the word is Hawaiian and means "stony rough lava").
Naturally it will break with a rough surface, before it is used it is often polished to a smooth surface, large blocks are removed from quarries that have smooth surfaces from the saw.
it's called 'a'Ä (often written as aa)
aa (pronounced ah-ah)
Why are the cooling fins at the back of the refrigerator usually painted black and have a rough surface?
Usually it is rough so anything in there or by the inside can be broken up, I think.
They are faster on the rough surface.
The rough endoplasmic reticulum has ribosomes on its surface. This is what make is "rough"
Its surface is rough because of all the rock's and crater's in its surface.
The rough surface is better than the smooth surface for the frictional force to act.
when light hits a rough surface it scattters.
The Rough Endoplasmic Reticulum (Rough ER) has ribosomes on its surface.
The rough endoplasmic reticulum has ribosomes embedded on its surface. This is why it is called the rough endoplasmic reticulum.
A rough surface has more surface area which allows more heat to be transferred.
Reflection of light from a rough surface is known as "Diffused" or "Irregular" reflection, because the light rays are barely seen after the reflection of light from a rough surface.
as we know that suction pump stick on a smooth non-porous surface but rough surface contains pores due to which suction pump is not able to maintain grip with the rough surface.
When light hits a rough surface it is scattered according to the refractive index of the surface. The rougher the surface, the duller that it will seem.
The moon's surface is rough - due to numerous impacts from meteorites
Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.
No because an object is much more easily pushed on a smooth surface than a rough because the rough surface will take more effort and energy because of it harsh surface
A rough surface is said to have a "diffuse" reflection. This means that light hitting the surface is scattered in a bunch of different directions.
the rough surface creates more friction as to that of soft surfaced ones
The rough surface is there to prevent people slipping over, especially if wet.
I would say, very rough since meteors and other things have crash onto the moon's surface, so it would be very rough
no zinc is not rough it's surface is smooth
Rough surfaces have more friction than the smooth surfaces. For ex: Carpet is a rough surface, ice is a smooth surface so carpet surface have more friction and ice surface have less friction.
It can reflect off a rough surface but the image is not clear ,causing an irregular reflection.
True, but only to a point. If the surface is too rough debris can get lodged between the wheels causing them to lock up. Which generally will lead to your face meeting the previously mentioned rough surface. However if the surface is not rough enough then it is difficult for the wheels to get a grip on the surface. Which usually will also lead to a meeting between the very smooth surface and your face.
Rough surfaces form irregular surface increase the surface area. Catalytic action is directly proportional to the area of contact.
on a smooth surface
mars is rough because of it craters
The ribosomes on the surface of the ER.
True. Ribosomes stud the surface of rough endoplasmic reticulum.
There are ribosomes on the surface of the rough endoplasmic reticulum - these are ovular in shape and so make the surface appear 'rough'. Ribosomes are the site of protein synthesis - so this the rough ER is involved in the production of protein.
Rough endoplasmic reticulum(RER), called "rough" because of the ribosomes on its surface. On the surface where the ribosomes are absent its called Smooth Endoplasmic Reticulum (SER)
Plutos surface is rough blue.
Depends on the surface, sandpaper usually.
The rough endoplasmic reticulum has ribosomes attached to its surface, giving it a studded, "rough" appearance. Ribosomes are small organelles that manufacture proteins in a cell. Conversely, the smooth endoplasmic reticulum has no ribosomes attached to its surface.
The Rough ER has a surface covered by mitochondria - which appear as small circles, and make the surface "rough" in appearance. The Smooth ER does not have these ribosomes, and so the surface is just one smooth line.
No, the name Rough Endoplasmic Reticulum comes from the 'rough' appearance when seen under an electron microscope. The 'rough' bits are ribosomes which stud the surface. Smooth Endoplasmic Reticulum has no 'rough' bits ie. no ribosomes.
The light rays are deflected off at the same angles as the angles on the rough surface.
Why are images reflected from a rough surface not as clear as those reflected from a smooth surface?
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.
howercraft can move on rough surface
Ribosomes attached to the rough ER make the surface appear bumpy.
Yes, rough surfaces absorb more light than smooth surfaces. A rough surface has more surface area, which allows more light to be transferred.
What produces more heat rough surface and a smooth or surface two smooth surfaces or two rough surfaces or two surfaces with oil between them?
two rough ones - there will be more friction xx
