Convection of liquid in the metal core,
Evidence from safari to explain:
heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them.
Yes, that's correct. That's a big part of the reason why
the soap floats in water and the sponge sinks in it.
To solve this problem it is necessary to apply the concepts related to the relationship between tangential velocity and centripetal velocity, as well as the kinematic equations of angular motion. By definition we know that the direction of centripetal acceleration is perpendicular to the direction of tangential velocity, therefore:

Where,
V = the linear speed
r = Radius
Angular speed
The angular speed is given by


Replacing at our first equation we have that the centripetal acceleration would be



To transform it into multiples of the earth's gravity which is given as
the equivalent of 1g.


PART B) Now the linear speed would be subject to:



Therefore the linear speed of a point on its edge is 51.05m/s
The simplest compound of hydrocarbon is methane
- The formula is CH_4
- It belongs to alkane group and has single bonds.
The electron structure attached
The force exerted by each team is 30 N. The forces are in the direction opposite to each other.
Force exerted by team 1, 
Force exerted by team 2,
Net force, 

Therefore, net force on the rope is 0 N.
