A metal alloy bolt is initially at 100.0°C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperat

ure of 20.0°C. After stirring, the final temperature of both bolt and water is 25.0°C. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g ∙ K), what is the heat capacity of the bolt in J/K?

Answer:

the heat capacity of the bolt is 13.9 J/K

Explanation:

J/K is short of " joule per kelvin", is the international system unit of heat capacity

heat energy = (mass of substance)(specific heat)(change in temperature)

Q = mc∆T

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆ is a symbol meaning "the change in"

∆T = change in temperature (Kelvins, K)

Heat gained by water = heat lost by copper  = Q = mC∆T = (50 g)(4.18 J/g/deg)(5 deg) = 1045 J   = C x ∆T

C = 1045 J/75 = 13.9 J/deg

1. Under a shipment contract, the seller is required only to the goods into the hands of a carrier and title passes to the buyer
taurus [48]

Answer:

<h2>1) The answer is option a) or True.</h2><h2>2) Generally all contracts are assumed to be <u>Shipment </u> contracts if nothing to the contrary is stated in the contract.</h2><h2>3) The seller is required to deliver the goods to a particular destination in a destination contract,usually directly to the <u>buyer</u><u>.</u></h2><h2>4) The answer is option a) or True.</h2><h2 />

Explanation:

  1. A shipment contract mandates that the seller of any good or service is obligated to deliver the specified shipment to a common carrier for delivery to the buyer but not directly to the buyer's destination.Under  the shipment contracts,the seller is not responsible for the condition of the shipment or package during the delivery point and time to the buyer.
  2. If nothing is specifically mentioned in the contract regarding the delivery of the shipment,it assumably qualifies as a shipment contract and the seller is only liable to dispatch the shipment to the transportation carrier and not obligated to send it directly to the buyer's destination.
  3. Under a destination contract,the seller is officially obligated to dispatch the concerned goods or shipment directly to the buyer's actual destination.Hence,the seller's obligation is incomplete until the shipment subsequently reaches the buyer's destination.
  4. For destination contract,at the point of delivery,the burden of risk and title associated with the condition and ownership of the specified shipment is passed onto the buyer and seller is not officially or legally liable regarding the same.

Oscar has negotiated a lease for his sporting goods store in which he is required to pay $2,500 per month in rent. Oscar pays hi
AfilCa [17]

Answer:

The Oscar's fixed costs per month is $2,500

Explanation:

Fixed cost: The fixed cost is that cost in which the amount is remain fixed whether production level change or not, that means it does not have any effect on the production level.

In the given question,

Monthly rent is $2,500 which is fixed so, it would be considered as fixed cost

The per hour pay and electrical bill depend upon the total hours of operation which means if the more hours, the workers are engaged so more pay will be give to them, and more electricity bill come.

And if they are working few hours, than less rate and less electrical bill will be there which reflects the variable cost. So, these cost are considered variable cost. Thu, it would not be included in the fixed cost.

Hence, Oscar's fixed costs per month is $2,500

At December 31, Gill Co. reported accounts receivable of $238,000 and an allowance for uncollectible accounts of $600 (credit) b
Firlakuza [10]

Answer: $7,740

Explanation:

Given, At December 31, Accounts receivable = $238,000

Allowance for uncollectible accounts = 3% of (accounts receivable)

∴ Allowance for uncollectible accounts = 3% of ($238,000 )

=$(0.03 ×238,000)                [3% = 0.03]

= $ (7140)

= $7,140

Allowance for uncollectible accounts (credit) before any adjustments= $600

The amount of the adjustment for uncollectible accounts = Allowance for uncollectible accounts +  $600

= $7,140 +  $600

= $7,740

Hence, The amount of the adjustment for uncollectible accounts would be: <u>$7,740.</u>
