Answer:
divergent
Explanation:
When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
The answer would be a radio wave
Answer:
Below
Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s

Answer:
![a=\frac{mBg-mAgSin\theta}{mA+mB}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BmBg-mAgSin%5Ctheta%7D%7BmA%2BmB%7D)
Explanation:
Given two mass on an incline code
and
and an angle of inclination
.
. Assume that
is the weight being pulled up and
the hanging weight.
-The equations of motion from Newton's Second Law are:
where a is the acceleration.
#Substituting for
(tension) gives:
![mBg-mAsin\theta-mAa=mBa](https://tex.z-dn.net/?f=mBg-mAsin%5Ctheta-mAa%3DmBa)
#and solving for ![a:](https://tex.z-dn.net/?f=a%3A)
which is the system's acceleration.
