1) Force is a quantity that is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N." To say "10.0 N" means 10.0 Newton of force. One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. 2) The Principle of Moment states that when a system is in equilibrium the sum of its CLOCKWISE MOMENTS equals the sum of its ANTICLOCKWISE MOMENTS. Some examples where moments (turning effect) are applied involve levers, like seesaws, opening and closing doors, nutcrackers, can openers, and crowbars. 3) the size of the force applied.
the perpendicular distance from the pivot to the line of action of the force. 4) The principle of moments states that when in equilibrium the total sum of the anti clockwise moment is equal to the total sum of the clockwise moment. When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out. 5) Force is equal to mass times acceleration. Force is measured in Newtons. You can use the force equation to also find the mass or acceleration of an object. To calculate the net force acting on an object, it helps to draw a free body diagram.
Hi!
14. Star clusters are held together by gravity. It really depends how old a star in the cluster is - it could be just born, or could have been born hundreds of billions of years ago. Astronomers categorize them by different colors, temperatures, sizes, brightness, etc.
15. Open clusters eventually disperse to form field stars.
16. Our sun is not part of a cluster (although it used to be).
17. Globular clusters<span> </span>are<span> found in the ring of a galaxy and usually contain more stars and </span>are<span> much older than the </span>open clusters.
18. Omega Centuari and M13.
Hope this helps!
Answer:
Explanation:
- Oceanic Plate
- Subduction Zone
- Convection Currents
- Asthenosphere
- Continental Plate
The Oceanic Plate is located near the ocean ridge. Which represents where magma creates new oceanic crust.
The Subduction Zone is where the tectonic plates meet. These are called plate boundaries.
Convection Currents are what drives the movement of rigid tectonic plates in Earth's molten mantle.
The Asthenosphere is the upper layer of the mantle. Which is below the lithosphere (Continental Plates).
Continental Plates are the outer shell of the mantle.
