Answer:

A puck hovers and glides across an air track at constant velocity is the scenario where a non-conservative force acts(air friction)

Explanation:

Conservative forces are the forces which are path-independent.

so, total work done by conservative forces in a closed loop is zero

Now, non-conservative forces are path-dependent forces.

These are dissipative forces in nature, so total work done by non-conservative forces is not zero.

Option a) A puck hovers and glides across an air track at constant velocity.

Even though puck moves with constant velocity there will air drag force which is friction and non-conservative in nature. so, to keep puck to move with constant velocity we need to compensate this friction.

Option b) A dishwasher was pulled up to a window by a rope using a pulley system.

Here, work is done against gravitational force which is conservative in nature.

Option c) A feather falls from one end of a tube to the other inside a vacuum.

Here, there are no forces. feather just moves in vacuum, so, the work done is also zero.

Option d) A charged particle was pushed away by another charged particle.

here, these are forces generated by electric charges, which are similar to gravitational force. so, these are also conservative forces.

ivolga24 [154]

Michelle must give Luis a sixty-day written notice of the lease termination because he has lived in the property for more than one year.

Explanation:

The landlord must send a 30-day notice of termination in writing with the occupant at the cost of his will, unless the owner stays in the house for more than one year, which includes a notice of 60 days.

The 60 Days Lease Termination Letter is an appointment for a residential property owner to use when he wishes to vacate a tenant for at least a year or more after residing in the house.

In California, a landlord can terminate a rental after a tenant has spent a year or more on the property and has provided the tenant with a notice of sixty days.

Both the Onus ferry operator in the monopoly market and each of the Yuri ferry operators in the perfectly competitive market wil
Lisa [10]

Answer: Please refer to Explanation.

Explanation:

Monopoly.

The 2 reasons why the monopoly’s marginal revenue will always be less than its price are;

a) Even though Monopolies have very large influence on the prices of goods and services they offer, for a Monopoly to sell more goods, they generally have to lower their prices. This will lead to a situation where Marginal Revenue, which is the additional revenue made per additional unit sold will be less than Price because additional revenue for a new unit will be less than the last one because prices are dropped .

b) A Monopoly's demand schedule is downward sloping. This means that demand rises as prices drop. As prices drop therefore, more goods will be sold but the marginal revenue will be less because prices had to be dropped to get an additional unit to be sold. That unit therefore will bring in less revenue than the last unit.

Perfectly Competitive Market

In such a market, the seller is a Price Taker. This means that sellers in this market do not sell at a price that they want but rather at a price the market has established to be the Equilibrium. This is because of the high competition in the market. Since they are all selling at the same price, this means that every additional revenue they get is the same as the price the market charges. This means that Price equals Marginal Revenue in this market.

laiz [17]

Answer:

E. Ursula is likely to prevail because an enforceable unilateral contract exists based on her provision of information leading to the capture of Victor.

Explanation:

A unilateral contract is in existence because safe bank has made an offer to pay $10,000. And in a unilateral contract when an offerer like safe bank makes an offer, the offer is accepted through actual performance which Ted has done through information Ursula provided. Therefore Ursula would prevail because unilateral contracts are enforceable by the law.

PilotLPTM [1.2K]

Answer:

An increase in your income causes you to buy more hamburgers.

Explanation:

An increase in your income causes you to buy more hamburgers.

Option "A" is correct because the increase in income exhibits an increase in purchasing power. Moreover, there is a positive relationship between the income the demand for normal goods which means if the income rises, then the demand rises. If the income falls, then demand for goods also falls. Therefore, option "a" is right.
