Answer:

Explanation:

Near the earth's surface where gravity is approximately 10 m/s² downward

v = u + at

v = 5 + (-10)(1) = -5 m/s

so it has the same speed but in the opposite (downward) direction.

What dose fixed supply mean? Tell what a fixed supply curve looks like and heat it’s appearance means
devlian [24]

Answer:

The quantity of some goods or productive factors is totally fixed, whatever their price, for example, there is only one Mona Lisa from Da Vinci.

Explanation:

Nature's original endowment of land can also be considered fixed. A rise in the price offered for land cannot create yet another corner at the junction of 57th Street with Fifth Avenue in New York City. A rise in the pay of famous athletes is unlikely to alter their effort. When the quantity supplied is constant at all prices, what is paid to use such a factor of production is called economic rent or pure economic rent.

When supply is independent of price, the supply curve is vertical in the relevant interval. The land continues to contribute to production regardless of its price. The increase in demand for a fixed factor only affects the price. The quantity supplied does not vary and the rise in price is exactly the same as the upward shift in demand.

When a tax is applied to a fixed good or service, it is paid entirely by (or "transferred" to) the supplier (for example, by the landowner), who absorbs it in its entirety, losing part of its economic income. The consumer buys exactly the same amount as before the good or service without costing mor

The distance to the other planets in the Solar System from the Earth depends on where they are in their orbit. The closest that
Afina-wow [57]

Answer:

3.6 arcsec

Explanation:

 angular diameter = diameter / distance

diameter is constant

so angular diameter ∝ 1 / distance

angular diameter = k / distance

For first case ,

18 = k / .5

for second case let angular diameter be D .

D = k / 2.5

dividing ,

D / 18 = .5 / 2.5 = 1 / 5

D = 18 / 5 = 3.6 arcsec

3.6 arcsec is the answer .

frozen [14]

Answer:

Ionic.

Explanation:

To know the the correct answer to the question given above, let us define the terms covalent and ionic.

Covalent is the term used to characterise a compound which is formed by sharing of electrons between the atoms involved. Thus, the compound formed is called covalent compound.

Ionic is the term used to characterise a compound formed when there is a transfer of electron(s) from the metallic atom to the non-metallic atom. The compound formed is called ionic compound.

Considering the question given above, since the calcium atom transfer electron(s) to the carbon atom, it means the compound is an ionic compound.
