The answers would be:
CONVERGENT boundary - Crust submerges into the mantle
TRANSFORM boundary - neither forms nor submerges
DIVERGENT boundary - new crust forms
If you'd like to know more about the different boundaries, read on:
Convergent boundaries occur when two plates move TOWARDS each other. The event where crust submerges into the mantle is called <em><u>subduction</u></em> and this occurs when an oceanic plate and a continental plate collide. The oceanic plate is more dense and thinner than the continental plate, so it slides under it.
Transform boundaries occur when two plates slide against each other. They move slide side by side, so nothing is formed nor do they go under each other. Although, this type of boundaries create strong earthquakes.
Lastly, divergent boundaries occur when two plates move apart. The separation creates a way for magma to come up. New crust is formed when the magma that seeps out is cooled by its cooler surroundings. This is observed in the mid oceanic ridge.
Answer:
4748.4
Explanation:
The first number after the decimal is the tenths place and when it says round it means look at the number after it and if it's above four then raise the tenths place by one.
Refraction: It is the phenomena of bending of light when it changes it medium. This can rarer to denser or denser to rarer. Refraction and Diffraction are just bending of light. Whereas, Reflection is getting back the light you've thrown from a source of light.
Answer:
The centripetal acceleration will be "21.785 m/s²".
Explanation:
The given values are:
Time,
t = 0.85 seconds
Length of rope,
r = 0.40 m
Mass of ball,
m = 0.80 kg
As we know,
⇒ ![w=\frac{2 \pi}{t}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%20%5Cpi%7D%7Bt%7D)
On substituting the values, we get
⇒ ![=\frac{2\times 3.14}{0.85}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%5Ctimes%203.14%7D%7B0.85%7D)
⇒ ![= \frac{6.28}{0.85}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B6.28%7D%7B0.85%7D)
⇒ ![=7.38 \ rad/s^2](https://tex.z-dn.net/?f=%3D7.38%20%5C%20rad%2Fs%5E2)
The centripetal acceleration will be:
⇒ ![a=r\times w^2](https://tex.z-dn.net/?f=a%3Dr%5Ctimes%20w%5E2)
⇒ ![=0.40\times (7.38)^2](https://tex.z-dn.net/?f=%3D0.40%5Ctimes%20%287.38%29%5E2)
⇒ ![=0.40\times 54.46](https://tex.z-dn.net/?f=%3D0.40%5Ctimes%2054.46)
⇒ ![=21.785 \ m/s^2](https://tex.z-dn.net/?f=%3D21.785%20%5C%20m%2Fs%5E2)
