The major financial flop that led to the end of the Sega Dreamcast and ultimately caused Sega to stop making game consoles altogether is:

3: A game called Shenmue, that cost more than $70 million to make, meant that everyone who owned a Dreamcast needed to buy two copies of the game just for Sega to make back the money they had spent to develop it-which didn't happen.

Explanation:

Shenmue, released on December 29, 1999, was created for Dreamcast by Suzuki.  It was widely described as the most expensive video game ever produced.  It had an estimated production and marketing cost of between US$47 and $70 million, according to the latest available data.

The order of evaluation in expressions with different types of operators is determined by operator precedence.

Operator precedence is a set of rules that dictate the order in which operations are performed in an expression. The operators with higher precedence are evaluated before those with lower precedence. For example, multiplication and division have higher precedence than addition and subtraction, so they are performed first in an expression. The order of evaluation can also be affected by parentheses, which have the highest precedence and can be used to override the default order of evaluation. Additionally, the short circuit operators (&& and ||) have special rules for evaluation, in which the second operand is only evaluated if necessary. The assignment operator (=) has the lowest precedence and is always performed last. The placement and data types of operands do not affect the order of evaluation.

The work done by a 10 HP motor when it raises a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

Define work. Explain the rate of doing work.

Work is the energy that is moved to or from an item by applying force along a displacement in physics. For a constant force acting in the same direction as the motion, work is easiest expressed as the product of force magnitude and distance traveled.

Since the force transfers one unit of energy for every unit of work it performs, the rate at which work is done and energy is used are equal.

Solution Explained:

Given,

Weight = 1000N and distance = 5m

A/Q, the work here is done in lifting then

Work = (weight) × (distance moved)

         = 1000 X 5

         = 5000Nm or 5000J = 5kJ

Therefore, the work done in lifting a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

Answer:

It only detects errors if an odd number of bit flips have occurred.

Explanation:

Parity is a measure of how even or odd a string of digits (for example, a string of binary units is).  It is obtained by calculating the value of all the bits. Parity is used in error detection. A parity error is detected when the parity and the odd number of bits are incorrectly propagated.

A problem commonly associated with the parity bits is that they can only detect an odd number of bit errors. This means that if a digit is corrupted in the even binary digits there would be an incorrect detection of errors.

The probability that one telephone call passes through the switchboard in three minutes is 1.49%.

Using the Poisson probability formula, we can calculate the probability of exactly one call passing through the switchboard in 3 minutes as follows:

P(X = 1) = (e^(-6) * 6^1) / 1!

Where

6 = 2 per minute * 3 minute

X is the number of calls passing through the switchboard in 3 minutes.

So, we have

P(X = 1) = (e^(-6) * 6^1) / 1!

= (0.00248 * 6) / 1

= 0.0149

Therefore, the probability that one telephone call passes through is approximately 0.0149, or about 1.49%.

The change in structural efficiency for both bending stiffness and strength when a solid flat panel of unit area and thickness t is foamed to give a foam panel of unit area and thickness h, at constant mass, can be calculated using (Offe*(p/Ps)^1/2)/(Ofs*(p/Ps)^1/2)

To calculate the change in structural efficiency for both bending stiffness and strength when a solid flat panel of unit area and thickness t is foamed to give a foam panel of unit area and thickness h, at constant mass, we need to use the given equation for the modulus E and strength Oy of foams which scale with relative density p/Ps as 3/2 Eles and offe) Ofis where E, of and p are the modulus, strength and density of the foam and Es, ofs and pathose of the solid panel.

First, let's consider the bending stiffness of the panels. The bending stiffness of a panel is proportional to its modulus of elasticity (E) and its moment of inertia (I). The moment of inertia is proportional to the thickness cubed (t^3) for a solid flat panel and (h^3) for a foamed panel. So, the bending stiffness of the solid flat panel is given by E*t^3 and the bending stiffness of the foamed panel is given by (3/2)*Eles*(p/Ps)*h^3.

Now, we can calculate the change in bending stiffness by dividing the bending stiffness of the foamed panel by the bending stiffness of the solid flat panel:

Change in bending stiffness = ((3/2)*Eles*(p/Ps)*h^3)/(E*t^3)

Next, let's consider the strength of the panels. The strength of a panel is proportional to its yield stress (Oy) and its cross-sectional area (A). The cross-sectional area is the same for both panels (unit area), so we only need to consider the yield stress. The yield stress is proportional to the relative density (p/Ps) to the power of 1/2 for both solid and foamed panels. So, the yield stress of the solid flat panel is given by Ofs*(p/Ps)^1/2 and the yield stress of the foamed panel is given by Offe*(p/Ps)^1/2.

The statement "If you drill below the potentiometric surface into a confined aquifer, any water found there can be artesian" is true.

An artesian well is one that does not require a pump to bring water to the surface. The water flows under its own pressure up to the surface level.

Aquifers are water-bearing geological formations that are of economic value to mankind because they contain a significant quantity of water. Aquifers are confined, semi-confined, and unconfined, depending on their location and the pressure exerted on them by other rock formations or soil.

The potentiometric surface of an aquifer is the imaginary surface to which water will rise in a well that taps a confined aquifer. The artesian water table is equivalent to the potentiometric surface.

A confined aquifer is one in which a less permeable layer of soil or rock, such as shale, clay, or igneous rock, covers the water-bearing formation. This layer is referred to as an aquitard. The water is confined by the aquitard's impervious nature and can only move through the confining layer via small channels.

When a well is drilled into a confined aquifer, the water that is encountered can be artesian. This means that the water is under enough pressure to flow freely to the surface without the use of a pump. A well drilled into an artesian aquifer can be an excellent source of high-quality water.

2,400 volt-amperes (20 x 120 = 2,400) can be carried by a 20-ampere, 120-volt branch circuit. A 20-amp branch circuit can support a maximum of three devices (2,400 x 750 = 3.2 = 3).

Each outlet for a heavy-duty lamp holder must be estimated at a minimum of 600 volt-amperes in line with Section 220.14(E). Multiply 600 volt-amperes by 125 percent because the load is continuous (600 x 125 percent Equals 750 volt-amperes). 2,400 volt-amperes (20 x 120 = 2,400) can be carried by a 20-ampere, 120-volt branch circuit. A 20-amp branch circuit can support a maximum of three devices (2,400 x 750 = 3.2 = 3). For 16 outlets with heavy-duty lamp holders, six 20-ampere branch circuits are needed.

An inaccurate result can be obtained by first determining the total volt-amperes of all the heavy-duty lamp holders and then dividing that number by the number of volt-amperes in each 20-ampere branch circuit. For instance, 16, multiplied by 600 volt-amperes, is 9,600 volt-amperes (16, multiplied by 600 = 9,600 volt-amperes).
