Answer:

I think it does not have a specific shape

Explanation:

Irregular galaxies have no definite shape, which means that the second option is correct. They are definitely not round.

The "spiral galaxy" is the type of galaxy that has arms that extend from the center. These arms look "spiral," which influenced its name.  

They are actually smaller than the other types of galaxies. This makes them prone to collisions.

A 97.6-kg baseball player slides into second base. The coefficient of kinetic friction between the player and the ground is μk =
Mila [183]

Answer:

v=6.65m/sec

Explanation:

From the Question we are told that:

Mass m=97.6

Coefficient of kinetic friction  \mu k=0.555

Generally the equation for Frictional force is mathematically given by

 F=\mu mg

 F=0.555*97.6*9.8

 F=531.388N

Generally the  Newton's equation for Acceleration due to Friction force is mathematically given by

 a_f=-\mu g

 a_f=-0.555 *9.81

 a_f=-54455m/sec^2

Therefore

 v=u-at

 v=0+5.45*1.22

 v=6.65m/sec

How is heat transfer involved in the movement of tectonic plates?
Simora [160]

Mantle convection

Explanation:

The driver of moving plates is the mantle convection.

Convection is a heat transfer process that involves the movement of fluids from one place to another.

How does convection occur in the mantle?

  • Part of the mantle known as the asthenosphere is a hot liquid. It moves slowly and does not readily flow.
  • Over riding the asthenosphere is the brittle lithosphere made up of the upper mantle and the entirety of the crust.
  • The asthenosphere is at a higher temperature compared to the lithosphere on top.
  • In order to achieve stability and thermal equilibrium, the asthenosphere rises to the surface whereas the dense and cold lithosphere sinks down.
  • This way a convective cell is set up.
  • Hot materials rises to the surface because they are light whereas cold materials on the surface sinks into the asthenosphere.
  • Through this the plates moves.
