Answer: SOLUTION
Explanation: A technological design is often adopted when there is a need to solve or find solution to a certain or identified problem. The technological design process is often required in other to develop technologically driven products which is capable of providing solution to a perceived problem. The steps involved includes;
Identifying the problem at hand, carrying out further and thorough research on them, proferring possible solutions out of which the best possible approach is selected. Then the solution is modeled, the model is tested and refinements are made depending on outcome of the test. Testing will have to be repeated upon refinement of the model before the final outcut is communicated.

Answer:
Volume of the tank = 3m³
Mass of total water = 3,000 kg
Explanation:
Given:
Measurement of tank = 2m × 1.5m × 1m
Density = 1,000 kg/m³
Find:
Volume of the tank.
Mass of total water.
Computation:
⇒ Volume of the tank = lbh
Volume of the tank = 2m × 1.5m × 1m
Volume of the tank = 3m³
⇒ Mass of total water = Volume of the tank × 1,000 kg/m³
Mass of total water = 3m³ × 1,000 kg/m³
Mass of total water = 3,000 kg
Answer:
length x width x height = volume
2 x 1.5 x 1 = 3m
3m^3 is the volume
1000 km/ m^3 x 3m^3 = 3000^3 km

Compute the conductivity of a conductor with a length of 2.0 cm and a cross-sectional area of 0.060 cm2, whose conductance is 3.5 x 103 ohms. σ = _____ ohm-1cm-1 A: 1.2 x 10 5 B: 2.9 x 10 -4 C: 1.1 x 10 2 D: 1.9 x 10 6
Answer: A
Explanation:
You are given the following parameters:
Length L = 2.0 cm and
cross-sectional area A = 0.060 cm^2
Conductance = 3.5×10^3 ohms
Conductance is a reciprocal of resistance R
Conductance = (σ × A)/L
Where σ = conductivity
Substitutes all the parameters into the formula
3.5×10^3 = (0.06 × σ)/2
Cross multiply
7×10^3 = 0.06σ
Make σ the subject of formula
σ = 7000/0.06
σ = 116666.67 ohm-1cm-1
σ = 1.2 ×10^5 ohm-1cm-1 approximately
Answer:
1.2 ×10^5

What is the slope of the line plotted below?
A. 1
B. -2
C. 2
D.-1
Answer:
B. -2
Explanation:
Since the line is coming from the top left to the bottom right, you know the line is going to be negative.
If you take two points, so (0,1) and (1,-1), and use the formula y2-y1/x2-x1, after substitution you should get -1-1/1-0. If you simplify, the answer should be -2/1 or -2.
what is the difference between LEO and GEO satellites? PLS ANSWER FAST
Answer: LEO satellites are low earth orbiting whereas GEO satellites are geostationary earth orbiting satellites.
Explanation: Satellites in low Earth orbit, or LEO, are the closest devices to Earth. You'll often hear the terms GEO and GSO used interchangeably, but they’re not always the same. Both types of satellites sit at roughly 22,300 miles above Earth’s surface, but the way they orbit is different.

A lens of focal length 15.0 cm is held 10.0 cm from a page (the object ). Find the magnification .
Answer:
Magnification, m = 3
Explanation:
It is given that,
Focal length of the lens, f = 15 cm
Object distance, u = -10 cm
Lens formula :
[tex]\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}[/tex]
v is image distance
[tex]\dfrac{1}{v}=\dfrac{1}{f}+\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{15}+\dfrac{1}{(-10)}\\\\v=-30\ cm[/tex]
Magnification,
[tex]m=\dfrac{v}{u}\\\\m=\dfrac{-30}{10}\\\\m=3[/tex]
So, the magnification of the lens is 3.
Answer:
3.00 - Magnification.

Becky has a younger sister. If the sister was half Becky's age when Becky was 6, and Becky is now 70, how old is Becky's sister?
Answer:
67
Explanation:
Answer:
35
Explanation:
It's a trick question!
Because the younger sister was half the age of Becky when she was 6. She also has to be half the age of Becky today.
So, 70 ÷ 2 = 35

A 24.8 tall object is placed in front of a lens, which creates a -3.09 cm tall image. What is the magnification?
Answer: 0.125
Explanation:
Given that the
Object height U = 24.8 cm
Image height V = 3.09 cm
Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.
M = V/U
Substitute V and U into the formula above.
M = 3.09/24.8
M = 0.125
Magnification is therefore equal to 0.125 approximately
Answer:
-0.125.
Explanation:
The previous explanation is right except for that it doesn't take into account that the -3.09 is negative – therefore, the positive answer is incorrect.
-0.125 is correct on Acellus.

Which statement is true for objects in dynamic equilibrium?
Answer:
The correct answer to the question is objects have zero acceleration.
Explanation:
Before answering the question, first we have to understand dynamic equilibrium .
A body moving with uniform velocity is said to be in dynamic equilibrium if the net external forces acting on the body is zero. Hence, the body is under balanced forces.
If the external forces acting on a body is not balanced, then the body will accelerate which will destroy its equilibrium condition. Hence, the necessary and sufficient condition for a body to be in dynamic equilibrium is that the forces are balanced.
When a body is in dynamic equilibrium, the body moves with uniform velocity along a straight line unless and until it is compelled by some external unbalanced forces.
Hence, the rate of change of velocity or acceleration of the body will be zero.
Answer:
objects have zero acceleration.

Which of the following is an example of heat convection?
Answer:
Liquid inside a beaker on a hot Bunsen burner circulates and heats through constant motion.
Explanation:
Transmission of heat by convection requires the movement of a liquid or gas. An example would be liquid in a beaker heating up as hot and cold parts of the liquid constantly circulate, which further heats the liquid. Heat from the sun is considered radiation, and the other two answers are examples of conduction.
What is the resultant force?
8 NA
14 N
3N
3N
22 N
Answer:
option will be ''B'' 0N
Explanation:
There are two forces acting upward 8N and 14N which is equal to 22N(upward force)
since, 22N is also acting downwards
both the forces will cancel each other and the the outcome will be zero.
Now, there is a 3N force acting on the left and right. So, they too, will cancel each other and the result will be zero.

What happens to the gravitational force between two objects as the distance between them decreases?
Answer:
gravitational force increases
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are brought closer to each other, the force of gravitational attraction between them also increases.
Resistance and resistivity are related by a:
A: factor that is dependent on the length of the material
B: proportionality constant dependent on the source of the material
C: factor that is dependent on the area of the material
D: proportionality constant dependent on the identity of the material
Answer: D
Explanation: Resistance of current in a wire is directly proportional to the length of the wire and inversely proportional to the cross - sectional area of the wire. That is,
R = (rho × L)/A
Where
L = length of the wire
A = cross sectional Area of the wire
rho = resistivity = proportionality constant which depends on the quality of the wire.
Therefore, Resistance and resistivity are related by a:
proportionality constant dependent on the identity of the material.
The diagram illustrates the evolution of the universe, starting from the big bang. Each concentric circle represents a stage in the evolution as stated by the big bang theory. The arrows illustrate the changes that happened after the big bang and leading up to the stage where gases were formed that later led to the formation of stars and galaxies. Choose the inaccurate statements on the diagram.
Answer: The two correct answers are Universe became more dense and universe became less transparent.
Explanation: I took the test and those are correct
The incorrect statements on the diagram universe became more dense Universe became less transparent.
What is the universe?The universe is the whole cosmic system of matter and energy. The Earth, the Sun, the Moon, the planets, and the stars along with the dust, gases, and rocks form the universe.
The big bang is the theory that explains how the universe began. It says that the universe began with just a single point. It went on expanding and stretched to grow as large as possible. It is still now expanding.
