Answer:
25. Approximately 8.1 meters
26. North 1.31 km, and East 2.81 km
Explanation:
25.
Notice that the displacements: 6 meters east and 5.4 south create the legs of a right angle triangle. The hypotenuse of that triangle will be the distance (d) needed to cover in order to get the ball in the hole in one putt. That is:
\(d=\sqrt{6^2+5.4^2} =\sqrt{65.16} \approx 8.072\,\,\,m\)
which can be rounded to 8.1 m.
26.
Notice that the 3.1 km at an angle of 25 degrees north of east, is the hypotenuse of a right angle triangle that has for legs the east and north components of that distance.
We can find the leg corresponding to the east displacement using the cosine function (that relates adjacent side with hypotenuse):
\(east\,\, comp=3.1 * cos(25^o)\approx 2.809\,\,km\)
and we can calculate the north component using the sine function that relates the opposite side to the angle with the hypotenuse.
\(north\,\,component = 3.1 * sin(25^o) \approx 1.31 \,\,km\)

By separating actions that are motivated by obligation from those that are not, the first premise aids in the distinction between those actions that have moral value.
What is Mortality?The first involves a salesman who, even though he is aware of the customer's inexperience, does not overcharge them because he does not want to risk damaging his reputation by being found out.
Because the salesman was not driven by a sense of obligation to treat the consumer fairly, Kant claims that this is not a moral issue.
The second claim is that "an action performed out of obligation has its moral significance not in the goal that it is intended to achieve.

A train accelerates at a constant rate of 1 m/s2. It passes through a 24.5 m wide level crossing in a time of 2 s. After the train leaves the crossing, how much time is required until its speed reaches 31 m/s?.
Answers
A train accelerates at a constant rate of 1 m/s², then the velocity of the train after time t₁ will be equal to 15.25 m/s.
What is Velocity?Velocity is really the direction speed of an item in motion as a measure of the rate at which its location is changing as seen through a particular point of view and as determined by a specific unit of time. A key idea in kinematics, the area of classical physics that studies how bodies move, is velocity.
Acceleration, a = 1 m/s²
Distance, d = 24.5 m
Time, t = 2 s
Velocity, v₂ = 31 m/s
By the equation of motion,
v = u + at
v = v₁
t = t₁
v = v₁ - 4.2 (1)
24.5 = u(2) + 1/2(1)(2²)
u = 11.25 m/s
v₁ = u + 4
v₁ = 11.25 + 4
v₁ = 15.25 m/s.
Therefore, the velocity of the train after time t₁ is 15.25 m/s.

How are radio waves used on Earth?
Why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (Hint: What did the article say about the advantages of digital signals?)
Answers
2) Limitations of using electromagnetic waves in sending communication
communication is a process of transmitting and receiving information in the form of signals.high technology communication use electromagnetic waves,there are various types of electromagnetic waves which are used in communication which include radio-waves,microwaves,infrared e.t.c some of their limitations are
i)Because there is limited number of broadcast frequencies the use of transmitters must be restricted in some way or they will seriously interfere with each other.
ii)Through the air signals can be distorted by atmospheric conditions and signals from space are sometimes distorted by solar activity
iii)physical activities such as mountains and buildings can prevent or interfere with some transmissions
iv)Through the air signals are not private,so any tuned receiver within the range can pick up them.
3)Differences between digital and analogue signals
Analogue and digital signal are used to transmit information usually through electric signals.
An analogue signal is continuous wave denoted by sine wave and may varry in signal strength (amplitude) or frequency(time) an example is sound from human voice is analogue because waves are continuous..
A digital signal is a signal in which the original information is converted into a string of bits before being transmitted .example a must for computer processing where is described as using (0s and 1s)and therefore can not take any fractional value.
4)Advantages of using digital signals over analogue signals
one advantage of digital signals are inherently less susceptible than analog signals to interference caused by noise because with digital signal it is not necessary to evaluate precise amplitude,frequency or phase.
Another advantage based in capacity is that digital signals carry more information per second than analogue signals.
Digital signals maintain their quality over long distances better than analogue signals.
5)How we use digital and analogue signals in our everyday live
digital signal processing is the way of life of current generation
example is mobile phones do alot of digital signal processing .they process our our speech digitally to remove background noise,echo e.t.c
Television also do a lot of digital processing of video,audio signal to present them in a better way.
How radio telescopes are used to explore space
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.It has several main parts, a dish and antenna,a receiver,a detector and an analyzer.The dish collects the radio signals from space ad focuses them on the antenna.
6)How radio waves are used on earth
Radio waves are used to transmit television and radio programs They have longer wave lengths and are reflected by the ionosphere
7) Reasons why telescopes convert radio waves (analog) to electrical(digital) signals for analysis
This is because signals can be easily stored and transmitted in digital form.The analog is continuous in time and it is necessary to convert this to a flow of digital values.

The chloroplasts are therefore known as the kitchen of the cell.
c) Lysosomes are known as the suicidal bag of the cell because it is capable of destroying its own cell in which it is present. It contains many hydrolytic enzymes which are responsible for the destruction process. This happens when either the cell is aged or gets infected by foreign agents like any bacteria or virus.
d) Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule. ... In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product.
e) In Hydra, the cells are arranged in two germinal layers—outer ectoderm and inner endoderm. Between these two layers is a layer of undifferentiated cells called mesoglea. Such kind of pattern of embryonic layers is seen in diploblastic animals. Hence, Hydra is a diploblastic animal.

) The graph in the figure shows the position of a particle as a function of time as it travels along the x-axis.
What is the average velocity of the particle between t = 2.0 s and t = 4.0 s?
Answers
The average velocity of the particle between t = 2.0 s and t = 4.0 s is 4 m/2.0 s = 2.0 m/s.
What is average velocity?Average velocity is the rate of change of an object's position, expressed as a vector quantity that tells both the speed and direction of the object's motion.
The average velocity of the particle between t = 2.0 s and t = 4.0 s can be calculated by taking the difference in the x-position of the particle at t = 4.0 s and t = 2.0 s, and dividing it by the difference in the time.
The x-position of the particle at t = 2.0 s is 4 m and the x-position of the particle at t = 4.0 s is 8 m.
Therefore, the difference in the x-position is 8 m - 4 m = 4 m.
The difference in time is 4.0 s - 2.0 s = 2.0 s. Therefore, the average velocity of the particle between t = 2.0 s and t = 4.0 s is 4 m/2.0 s = 2.0 m/s.

define microgravity and a condition under which it can be produced.
Answers
Answer:
see below
Explanation:
Microgravity is a condition in which the gravitational force experienced by an object is very weak. It is characterized by a very small gravitational acceleration, typically less than one thousandth of that experienced on Earth's surface. The gravitational force experienced in microgravity is so small that it is often neglected in many physical phenomena.
A condition under which microgravity can be produced is by placing an object in a state of freefall. Freefall is the state in which an object is falling under the influence of gravity, but it is not in contact with a solid surface. When an object is in freefall, it experiences a condition of weightlessness, which is similar to microgravity.
One of the ways to produce microgravity is by being in orbit around the Earth, at an altitude of around 200 miles or more, the gravitational pull is weak enough to be considered as microgravity. This can be achieved by using spacecrafts or high-altitude balloons, where the object is in a state of free fall around the Earth, and it experiences microgravity.
Another way to achieve microgravity is by using aircrafts, such as the "vomit comet" that flies in parabolic trajectory, allowing the passengers to experience weightlessness for a few minutes during the flight.

What is the difference between special relativity and general relativity? Briefly describe each theory and cite one piece of evidence supporting each theory.
Answers
Special relativity and general relativity are both theories proposed by Albert Einstein. Special relativity deals with the laws of physics in the absence of gravity, while general relativity extends special relativity to include gravity and explains the curvature of spacetime caused by mass and energy.
Special relativity, proposed in 1905, deals with the laws of physics in the absence of gravitational fields. It introduces the concepts of time dilation and length contraction, stating that the laws of physics are the same for all observers moving at constant speeds relative to each other.
One piece of evidence supporting special relativity is the famous Michelson-Morley experiment, which failed to detect the existence of the hypothetical luminiferous aether.
On the other hand, general relativity, formulated in 1915, is an extension of special relativity that incorporates gravity. It postulates that gravity arises from the curvature of spacetime caused by mass and energy. General relativity explains the motion of celestial bodies, the bending of light in the presence of massive objects, and phenomena like black holes.
One piece of evidence supporting general relativity is the observed gravitational redshift, where light emitted from a source in a strong gravitational field is shifted to longer wavelengths.

#1 runs at 6 m/s. Player #2 runs at 8 m/s. How long does it take them to run into each other, and
where are they when it happens? (hint: set one end of the soccer field as "x = 0")
Answers
Answer:
See below
Explanation:
Closing speed is 6 + 8 = 14 m/s
for a 100 m field , they will cover this distance in 100 m / 14 m/s = 7.14 s
From the end of the field where #1 (6 m/s) starts this will be:
6 m/s * 7.14 s = 42.86 m
( player # 2 (8 m/s) will be 100- 42.86 = 57.14 m from his end of the field)
They meet each other after about 7.14 seconds, and they are both 42.84 meters from Player 1's starting point when it happens.
Let t be the time it takes for them to meet, and x₁ and x₂ be their positions at that time.
For Player 1:
x₁ = 0 + 6t
For Player 2:
x₂ = 100 - 8t
Since they meet at the same position (x₁ = x₂) and time (t),
0 + 6t = 100 - 8t
6t + 8t = 100
14t = 100
t = 100 ÷ 14
t = 7.14 sec
Now it takes 7.14 seconds for them to meet.
For Player 1:
x₁ = 0 + 6 × 7.14
x₁ = 42.84 m
For Player 2:
x₂ = 100 - 8 × 7.14
x₂ = 42.84 m
So, they meet each other after about 7.14 seconds, and they are both 42.84 meters from Player 1's starting point when it happens.

The Eiffel Tower in Paris weighs 9,000 tons and stands on an area of 450 m2. Find the pressure it exerts on the ground.
Answers
Answer: The question asks us to find the pressure exerted by the Eiffel Tower on the ground. To answer this question we use the formula
pressure=Force/Area
and obtain the answer Pressure exerted by Eiffel Tower on the ground =\(196000 Pa\)
Explanation: To find the pressure exerted by the Eiffel Tower on the ground we use the formula
\(pressure = \frac{force}{area}\)
Given in the problem, the weight of the Eiffel Tower= 9000 tons= 9000000 kg. Ton or kilogram(kg) is a unit of mass and we have to convert it into force
\(force = mass * acceleration\)
acceleration due to gravity \(g\) =9.8 m/\(s^{2}\)
mass = 9000 tons = 9000\(*\)1000 kg\(= 9000000 kg\) ∵\((1 ton = 1000 kg)\)
∴ \(force =\) \(9000000* 9.8\) = 88200000 N \((1 N(newton) = 1 kg.m/s^{2})\)
Given \(area = 450 m^{2}\)
∴\(pressure =\frac{force}{area}= \frac{88200000}{450} =196000 N/m^{2} = 196000 pascal= 196000 Pa\)
Thus the pressure exerted by the Eiffel Tower on the ground is 196000Pa

Identify the error(s) in the following proof: (Select all that apply:) wL is defined to be the set of all vectors in Rn that are orthogonal to every vector in W. Assume that W 0 WL {0}. Ifw ewn wL then w = 0. But this means that w 0. Thus 0 is only element of W n WL. We cannot assume W n WL = {0}_ WL is defined to be the set of all vectors in B" that are orthogonal to some vectors in W, not every vector. We cannot say w eWn WL U w = 0 does not imply w = 0

Since the first statement contains error, we must demonstrate that w intersect and w p equal only 0; hence, we cannot just assume that it is true.
How do you prove that a set is a subspace of RN?To prove that a set is a subspace of RN by check the closure of any arbitrary vectors x1 and xs when added to and multiplied by scalars. In other words, you simply need to determine whether a set is closed under addition and scalar multiplication to determine if it is a subspace of a vector space. Easy!.Since the first statement contains error, we must demonstrate that w intersect and w p equal only 0; hence, we cannot just assume that it is true. Therefore, the first statement is close to having a mistake. That is the mistake, then.To learn more about subspace refer to:
