The statement that the running time of a dynamic programming algorithm to fill in an M-by-N table is O(MN) is true.
The algorithm fills in each cell of the table one at a time, resulting in M*N operations, and the time complexity of the algorithm is proportional to the size of the table being filled.
When using a dynamic programming algorithm to fill in an M-by-N table, the running time of the algorithm is O(MN). This is because the algorithm fills in each cell of the table one at a time, which requires M*N operations. Since each operation takes a constant amount of time, the running time of the algorithm can be expressed as O(MN). Therefore, the time complexity of this dynamic programming algorithm is proportional to the size of the table being filled, which is M*N.

A rocket is launched from rest with a constant upwards acceleration of 18 m/s2. Determine its velocity after 25 seconds
Answer:
The final velocity of the rocket is 450 m/s.
Explanation:
Given;
initial velocity of the rocket, u = 0
constant upward acceleration of the rocket, a = 18 m/s²
time of motion of the rocket, t = 25 s
The final velocity of the rocket is calculated with the following kinematic equation;
v = u + at
where;
v is the final velocity of the rocket after 25 s
Substitute the given values in the equation above;
v = 0 + 18 x 25
v = 450 m/s
Therefore, the final velocity of the rocket is 450 m/s.

Surveying: If you're going to check for alignment of an earth

True or False
It is false that if you're going to check for alignment of an earth retaining system use of secondary horizontal control is sufficient
The use of secondary horizontal control alone is insufficient to verify the alignment of an earth retaining system.
Secondary horizontal control refers to reference points or control points that are set up far from where the retention system is immediately present.
Secondary control may not precisely reflect the precise alignment and geometry of the holding system, even if it can offer some information about the general alignment.
Establishing primary horizontal control on or near the retaining system is important to guarantee accurate alignment.

.If aligned and continuous carbon fibers with a diameter of 6.90 micron are embedded within an epoxy, such that the bond strength across the fiber-epoxy interface is 17 MPa, and the shear yield strength of the epoxy is 68 MPa, compute the minimum fiber length, in millimeters, to guarantee that the fibers are conveying an optimum fraction of force that is applied to the composite. The tensile strength of these carbon fibers is 3960 MPa.
Answer:
the required minimum fiber length is 0.80365 mm
Explanation:
Given the data in the question;
Diameter D = 6.90 microns = 6.90 × 10⁻⁶ m
Bond strength ζ = 17 MPa
Shear yield strength ζ\(_y\) = 68 Mpa
tensile strength of carbon fibers \(6t_{fiber\) = 3960 MPa.
To determine the minimum fiber length we make use of the following relation;
L = (\(6t_{fiber\) × D) / 2ζ
we substitute our given values into the equation;
L = ( 3960 × 6.90 × 10⁻⁶) / (2 × 17 )
L = 0.027324 / 34
L = 0.000803647 m
L = 0.000803647 × (1000) mm
L = 0.80365 mm
Therefore, the required minimum fiber length is 0.80365 mm

if the wall shear stress in a horizontal 50 m run of 400 mm diameter pipeline is 7.0 pa, what is the associated pressure drop in units of kpa? assume fully developed flow.
The pressure drop in a 50 m run of a 400 mm diameter pipeline with a wall shear stress of 7.0 Pa is 8.75 kPa.
To calculate the pressure drop, first, we need to find the friction factor (f) for fully developed flow.
Using the Darcy-Weisbach equation, we can relate wall shear stress (τ) to friction factor as follows:
τ = (1/2)ρv²f, where ρ is fluid density and v is fluid velocity.
Next, we can use the pressure drop equation: ΔP = f(L/D)(ρv²/2), where L is the pipeline length and D is the pipeline diameter.
Rearrange the equation for ΔP and substitute the known values, ΔP = (τ/ρ)(2L/D).
For simplicity, we'll assume a fluid density (ρ) of 1000 kg/m³.
Convert the diameter to meters (0.4 m) and calculate,
ΔP: (7.0 Pa / 1000 kg/m³)(2 * 50 m / 0.4 m) = 8.75 kPa.

Liquid methanol is pumped from a large storage tank through a 1-in.ID pipe at a rate of 3.00gal/mm.
(a) At what rate in (i) ft · lbf/s and (ii) hp is kinetic energy being transported by the methanol in the pipe?
(b) The electrical power input to the pump transporting the methanol must be greater than the amount you calculated in part (a). What would you guess becomes of the additional energy? (There are several possible answers.)
a) (i) The kinetic energy rate in ft.lbf/s is 0.00771
(ii) kinetic energy being transported by the methanol in the pipe is 1.40 x 10⁻⁵ hp
b) Additional energy is dissipated into other forms. The larger part is heat energy, but also dissipated in light, sound and vibrations.
What is kinetic energy?
The ability of an object to do work by virtue of its motion.
The mass flow rate expressed as
m= 3.00 gal.mm x 1000/264.17L/gal x 0.792 kg/L x 2.20462 / 60= 0.330 lb/s
The velocity is determined by the continuity equation
u= Q/A =[ 3.00 x 35.3145/(264.17x60) ] / π (1/12)²/4
u = 1.225 ft/s
The rate of kinetic energy transport is
K.E = 1/2 x (0.330) x (1.225)² = 0.00771 ft-lb/s
Thus, the kinetic energy rate in ft.lbf/s is 0.00771
The rate of kinetic energy in hp is
K.E = 0.00771 x 1.341 x 10⁻³ /0.7376
K.E = 1.40 x 10⁻⁵ hp
The kinetic energy being transported by the methanol in the pipe is 1.40 x 10⁻⁵ hp

From the producers, the energy flows to the consumers (primary consumers, secondary consumers, tertiary consumers.) Then the energy exits the ecosystem when an organism dies, and the energy is passed to decomposers.
The statement given "From the producers, the energy flows to the consumers (primary consumers, secondary consumers, tertiary consumers.) Then the energy exits the ecosystem when an organism dies, and the energy is passed to decomposers." is false because energy does not exit the ecosystem when an organism dies.
Instead, when an organism dies, the energy contained in its body is transferred to decomposers, such as bacteria and fungi, through the process of decomposition. Decomposers break down the organic matter of dead organisms and release the stored energy back into the ecosystem in the form of nutrients. These nutrients can then be taken up by producers (plants) through nutrient cycling, restarting the flow of energy through the ecosystem. This process ensures that the energy remains within the ecosystem and is continually recycled rather than exiting the system.

When the direct shear test is performed, what shear strength can be expected if the normal stress is 3000 lb/ft2
Answer:
shear strength = 2682.31 Ib/ft^2
