Eratosthenes lived in Alexandria of Egypt in BC 240.. He found out the diameter of Earth thorough geometry and mathematics. Hope this helps .. :)
Market economic system would promote people to buy more products and technology.
Explanation:
An economy in which demand and supply drives economic decision, like the investments, production and distribution of goods or services, and pricing is a market economy. A market is a central space of exchange through which people are able to buy or trade goods and services. A market economy develops free competition among the participants. The significant merits of the market economy are improved production, efficiency, and innovation.
Answer:
D. two objects, when touching, will exert forces on each other that are equal in strength but opposite in direction
Explanation:
The three Newton's Laws have to do with force interaction in bodies. Option A follows other laws that are not from Newton. Option B has more to do with energy conservation, not forces. Option C is actually one Newton's Law, but it's the second one. It describes how an object with certain mass changes its force as long as the body is in certain type of acceleration.
Finally, option D is Newton's Third Law and describes how two bodies with mass interact each other when they touch. Ine very body interaction, there al always 2 forces that meet, and depending on which angles they encounter, the resultant force can vary.
For example, when a person sits down, there's a force coming from him towards the chair; but at the same time, the chair pushes the body back with exactly the same force. There's no movement at all from the 2 bodies because the whole system is in equilibrium or the resultant force is equall to 0.
He made. a lot of money add that up from when de Guzman paid
Answer:
optical
Explanation:
Polarization fall under optical property of material.
Polarization is a property of certain electromagnetic waves in which the direction and the magnitude of electric field are related in some way. Plane polarized light consist of waves in which direction of vibration of waves is same for all waves. Light may be polarized by reflection or by passing it through filters.
