A sum of $500,000 will be invested by a firm two years from now. If money is worth 12%, what will be the worth of this investment 10 years from now?
Answer:
investment 10 years from now is $1,238,000 .
Explanation:
given data
sum = $500,000
rate = 12% =0.12
total time = 10 year
solution
as present value After 2 years from now is $500,000
so time period is now = 8 year ( 10 - 2 )
so we apply future value formula that is
Future value = present value × [tex](1+r)^{t}[/tex] ............1
put here value we get
Future value = $500,000 × [tex](1+0.12)^{8}[/tex]
Future value = $500,000 × 2.476
Future value = $1,238,000
so investment 10 years from now is $1,238,000 .

Find the amount of energy (Q) required to raise the temperature of the water in kilo joules (KJ).
Given mass of water m = 2kg = 2000g.
Temperature difference ΔΤ = T2 – T1 = 60 °C – 25 °C = 35 °C .
Specific heat of water = 4.18 J/g* °C .
Therefore, Q =
kilo joules.
Amount of energy required = 292.6 kJ
Explanation:
Amount of energy required is given by the equation ,
Q = m × C ×ΔT
where m is the mass of the water = 2000 g
C is the specific heat of water = 4.18 J/g°C
ΔT = Temperature difference = 60 - 25 = 35 °C
Applying these values in the above equation, we will get,
Q = 2000 g × 4.18 J/g°C × 35°C
= 292600 J
When joule is divided by 1000 we will get the amount of energy in kJ.
[tex]$ Q = \frac{292600}{1000} = 292.6 kJ[/tex]
So the energy required to raise the temperature of the water is 292.6 kJ.
A biotechnology company produced 225 doses of somatropin, including 11 which were defective. Quality control test 15 samples at random, and rejects the batch if any of the random samples are found defective. What is the probability that the batch gets rejected?
The problem is a hypergeometric distribution scenario, where we calculate the probability of a batch being rejected based on the presence of defective items in a random sample.
Explanation:The question is about calculating the probability that a batch of somatropin doses gets rejected based on a quality control sampling test. To find this probability, we need to consider the number of defective samples in the batch and the number of samples taken for the test. Given that there are 11 defective doses out of 225, we can calculate the probability that none of the 15 randomly chosen samples are defective (which means the batch is accepted) and subtract this probability from 1 to get the probability of the batch being rejected (due to finding at least one defective sample in the test).
Since this is an application of hypergeometric distribution, the exact calculation requires combinatorial analysis, which would provide the probability of picking 0 defective doses in a sample of 15 from a lot of 225 doses which includes 11 defects.

Explanation:
Given,
coefficient of kinetic friction = 0.1
Normal force on the hockey player = 800 N.
Frictional force acting on the hockey player = ?
Frictional force acting on the hockey player ca be calculated using the formula,
Frictional force = coefficient of kinetic friction x Normal force
substituting the values,
Frictional force = 0.1 x 800 = 80 Newtons.
Therefore, Frictional force acting on the Hockey player = 80 N.
2. Why are some constraints automatically applied by the software, but you must manually apply others?
Answer:
It is because constraints applied automatic by the software (CAD) are supposed to control relationships and geometry between lines, arcs and circles while those manually added are supposed to control the geometry to behave in the manner the user likes the sketch to appear when drawing.
Explanation:
CAD software enables creating sketches using the program by automatic allowing geometric constraints to perform the tasks.Geometry in lines, circles, and other geometric features show collaborating relation that facilitate sketching in the program.For example, two end points appear to make lines remain perpendicular.Other geometric constraints are parallel, and equal.However, the user can manually apply geometric constraints to a sketch to force the geometry in a manner that is suitable to the sketch drawn.That is why a user must manually apply others.

1. Consider the steady flow in a water pipe joint shown in the diagram. The areas are:
A1=0.2 m², A2=0.2 m², and Az=0.15 m². In addition, Fluid is lost out of a hole at
section 4, estimated at a rate of 0.1m/s. The average speed at section 1 and 3 are
Vi=5m/s and V3=12m/s, respectively. Find the velocity at section 2.
Answer:
-4.5 m/s
Explanation:
Assuming steady and incompressible flow and uniform properties at each section
[tex]V_1A_1+V_2A_2+A_3V_3+Q_4=0[/tex]
Here V is velocity of flow and A is area, Q is flow rate out of the leak, subscript 1-4 represent different sections
At the surface, is negative hence the equation above will be
[tex]-V_1A_1+V_2A_2+A_3V_3+Q_4=0[/tex]
Making the subject of the formula then
[tex]V_2=\frac {V_1A_1-A_3V_3-Q_4}{A_2}[/tex]
Substituting the given values then
[tex]V_2=\frac {(5\times 0.2)-(12\times 0.15)-0.1}{0.2}=-4.5 m/s\\V_2=-4.5m/s[/tex]
Introduce the systems found on an electric car, and on an internal combustion engine car.
The systems found on Electric car are- battery pack, Electric motors, Differentials etc.
The systems found on internal combustion vvehicles include- Engine, Flywheel, Propeller shaft, Governor, Pistons and Crankshaft among several other components.
Explanation:
Electrical cars are associated with an electric motor, battery pack and other car accessories. Their propulsive power sets them apart from conventional vehicles. They are driven by a battery pack which is rechargeable and in turn drives the electric motors connected to each of the wheels.
These cars are also conspicuous with the absence of a propeller shaft which provides the power to conventional gasoline vehicles. Instead of the shaft, individual motors present side by the wheels drive them. Depending on the car’s drive ratio (either 2*4 or 4*4), the electric motors present them with sufficient power. Other equipment such as differentials, steering and control unit remains more or less same.
Internal Combustion car- They are the class of conventional vehicles powered by the burning of gasoline in the sealed engine of the car. They are either petrol, diesel variant or gas-powered. The working can be explained as follows-
Gasoline fuel with high calorific value burns in a controlled environment to produce gas which drives the piston which is in turn connected to the crankshaft. The crankshaft is responsible for turning the vertical motion of the piston to the rotatory motion of a ball lever.
Several mechanical components such as spark plugs, differentials, flywheel, governors etc make up for the controlled environment in which the fuel is allowed to burn.

A city engineer knows that she will need $25 million in 3 years to replace toll booths on a toll road in the city. Traffic on the road is estimated to be 20 million vehicles per year. How much per vehicle should the toll be to cover the cost of the toll booth replacement project? Interest is 10%.
Answer:
$1.38
Explanation:
She will spend $25 million in 3 years at 10% interest is a case of Future Value of Annuity.
Therefore,
FV = A*((1+r)^n-1)/r
Where A = 25,000,000
r=10%=0.1
n=3
FV= 25000000*((1+0.1)^3-1)/0.1
FV=25000000*(1.331-1)/0.1
FV=25000000*(0.331/0.1)
FV=25000000*3.31
FV=$82,750,000
So it is estimated that 20million cars passes through the toll per year
Therefore,
Toll per vehicle per year = 82750000/2000000
=$4.14
Toll for the duration of the project
=4.14/3 =$1.38

During world war 1 what process replaced riveting for ship repair
During World War I, riveting remained the primary method for ship construction and repair, with no clear indication that it was replaced during the conflict. Advances post-war led to welding becoming the preferred technique due to its stronger joints and efficiencies.
Explanation:During World War I, the process that began to replace riveting for ship repair was not explicitly mentioned in the provided text, indicating that riveting remained a significant method of construction and repair during this period. However, industrial and technological advancements during and following World War I led to the development and adoption of welding techniques which eventually became more prominent in shipbuilding and repair. Welding offered advantages over riveting, such as stronger joints and a reduction in labor and materials. Nevertheless, during World War I itself, the text highlights the intensive use of riveting, with contests to speed up production and techniques to ensure parts made in different locations could be assembled efficiently on site.
The contribution of riveting to shipbuilding during World War I is underscored by the record set by John Omir and the detailed planning required to assemble ships like the SS Agawam, with parts prefabricated and riveted in various locations before assembly. This period marked a significant effort to boost production in the face of enemy threats, laying the groundwork for future shifts towards welding in ship construction and repair.
