Answer:
Explanation:
The frequency equation for waves is
where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
so
v = .26(25) and
v = 6.5 meters/second
Answer:
1)force:- force is an external affert by any body on an object.
2) force and motion are related to each other. force helps to create motion in any object.
3) frictional force
4) Newton
6. fuel is needed in space to power certain things like engines.
7. It couldn't, as the lowest speed acceptable to get into space is 7.9 km per second (28,440 km per hour). This is because to break into the barrier that no longer contains oxygen, you would need to be going at an extremely fast rate.
8. It involves Newton's 3rd law. The movement requires that same thrust to be thrown back, also.
9. There is no gravity. So, basically, you just float.
<u>Answer:
</u>
Earth convection occurs at the mantle layer
<u>Explanation:
</u>
The movement of less dense material above the more dense material is called as convection. The mantle is the layer that lies between the core and the crust of the earth. The mantle is composed of rocks containing silicon, magnesium, oxygen, aluminium, iron and other minerals.
The heat energy of the core is transmitted to the rock in the lower mantle. This makes the rock with less temperature that lies in upper mantle to move down slowly. Now the rocks that are pushed up is eventually cooled and again pushed down by the hotter rock from the lower mantle. This is called as convection in earth’s mantle .
