why a magnetic compass is used to determine direction

Answers

Answer:

compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials.

This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south.

a 3205.5 m
b 1548.75 m
c 76.13 m
d 761.3 m

Answers

Explanation:

Using Equations of Motion :

(1) v = u + at

24 = 6.5 + a * 210

a (Acceleration) = 0.083 m/s^2

(2) v^2 = u^2 + 2aS

S = 576 - 42.25 / 0.166

S (Distance travelled) = 3215.3 m

A student lefts a bouncy ball to 1.2m, then releases the ball. The ball bounces back up to 0.86m. Construct an explanation as to what happened to the energy.

Answers

Answer:

the decrease in energy is due to a transformational in internal energy of the body in the rebound.

Explanation:

For this exercise we can calculate the initial and final mechanical energy

        Em₀ = U = m g y₁

        [tex]Em_{f}[/tex] = U = m g y₂

we look for the variation of the energy

       ΔEm = Em_{f} - Em₀

       ΔEm = m g (y_{f} -y₀)

       ΔEm = m g (0.86 -1.2)

       ΔEm = -3.332 m

We can see that there is a decrease in mechanical energy, this is transformed into internal energy of the ball during the impact with the ground, this energy can be formed by several factors such as a part of the friction with the surface, an increase in body temperature or a deformation of the body; there may be a contribution from several of these factors.

In conclusion the decrease in energy is due to a transformational in internal energy of the body in the rebound.

Answer:

Please find the answer in the explanation

Explanation:

Given that a student lefts a bouncy ball to 1.2m, then releases the ball. The ball bounces back up to 0.86m. To Construct an explanation as to what happened to the energy, let first consider the difference in the two height of the ball.

The initial height = 1.2 metres

Final height = 0.86 metres

There is a loss in elastic potential energy of the ball. And the loss energy is due to the difference in the height of the ball under the gravity.

The loss in elastic potential energy is being converted to the gravitational potential energy.

We need to find the comparison between  system of measurement in the united states from the English system to the international system of units

Advantage :

The most advantage of SI unit is that it has only one unit for each quantity. It means, it is never needed to change from one unit to another unit and here is no changing factors for students to memorize.

Disadvantage :

The most disadvantage of english system is that it has more unit for each quantity. It means, it is needed to change from one unit to another unit and here is changing factors most for students to memorize.

Hence, This is required answer.

Transitioning to the International System of Units (SI) offers global standardization, simplicity, and consistency in measurements, promoting scientific accuracy and ease of communication. However, the process involves costs, potential resistance to change, and considerations of cultural and practical factors that need to be carefully addressed for a successful conversion.

Here's a comparison:

Advantages of converting to the SI system:

1) Global Standardization: The SI system is the most widely used system of measurement worldwide, ensuring uniformity and ease of communication in international trade, science, and engineering.

2) Simplicity and Coherence: The SI system is based on a decimal system, making conversions between units straightforward and logical.

3) Consistency and Interchangeability: SI units are based on well-defined standards and physical constants, providing a consistent and unambiguous way to express quantities, and improving the accuracy and reliability of measurements.

4) Learning and Education: Adopting the SI system in education can simplify the learning process for students and facilitate the understanding of scientific concepts, promoting scientific literacy.

5) Compatibility with Technology: The SI system is compatible with modern technology and scientific instruments, enhancing the accuracy and precision of measurements.

Disadvantages of converting to the SI system:

1) Transition Costs: Implementing a change in the entire measurement system can be costly, requiring new standards, education, and recalibration of equipment and infrastructure.

2) Resistance to Change: People who are familiar with the English system may initially resist adopting the SI system, leading to a learning curve and potential confusion during the transition.

3) Cultural Factors: The English system has been ingrained in the culture and everyday life of the United States, and some may argue for preserving the historical tradition of the system.

4) Potential Loss of Precision: In some cases, the SI system may result in rounded or approximated measurements, leading to potential loss of precision compared to the English system.

5) Mixing Units: During the transition period, there might be a mix of both systems, leading to potential errors or misunderstandings when using different units.

In summary, transitioning to the International System of Units (SI) offers global standardization, simplicity, and consistency in measurements, promoting scientific accuracy and ease of communication.

A bus travels 210 km south along a straight

path with an average velocity of 85 km/h to

the south. The bus stops for 25 min, then it

travels 230 km south with an average velocity

of 73 km/h to the south.

How long does the total trip last?

Answer in units of h.

Answers

Answer:

6.04 hr

Explanation:

The bus first travels a distance of 210 km south at an average velocity of 85 km/h. The time, t it takes to cover this distance is gotten from d = vt and t = d/v where d = distance and v = velocity.

So, t = 210 km/85 km/h = 2.47 h

The bus then stops for 25 min. We convert 25 min to hours by dividing by 60.

So 25 min = 25/60 hr = 5/12 h = 0.42 h

The bus then travels 230 km south at an average velocity of 73 km/h.

The time it takes to cover this distance is t = 230 km/73 km/h = 3.15 h

So, the total time for the trip is the sum of each individual time, which is 2.47 h + 0.42 h + 3.15 h = 6.04 hr

So, it takes 6.04 hr for  the total trip

Answers

Answer:

100m/s

Explanation:

velocity = displacement/time

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.

What is Average Velocity?

Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.

It is expressed as;

Velocity = displacement / time

It can also be expressed as;

Velocity = circumference / time = 2πr / t

Given the data in the question;

Radius of the track r = 500mTime elapsed t = 50sAverage velocity V = ?

To determine the average velocity, we substitute our values into the expression above.

V = 2πr / t

V = ( 2 × 3.14 × 500m ) / 50s

V = 3140m / 50s

V = 62.8m/s

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.

A ball is thrown upward. The total time the ball remains in the air is 14 s. a) With what speed was the ball thrown upward? b) What is the maximum height reached by the ball?

Answers

Answer:

a) Vi = 137.2 m/s

b) h = 960.4 m

Explanation:

a)

In order to find the initial speed we will use first equation of motion:

Vf = Vi + gt

where,

Vf = Final velocity = 0 m/s (since ball stops at highest point)

Vi = Initial Velocity = ?

g = - 9.8 m/s² (negative sign for upward moyion)

t = time interval = 14 s

Therefore,

0 m/s = Vi + (-9.8 m/s²)(14 s)

Vi = 137.2 m/s

b)

Now, we use second equation of motion to find height (h):

h = Vi t + (1/2)gt²

h = (137.2 m/s)(14 s) + (1/2)(-9.8 m/s²)(14 s)²

h = 1920.8 m - 960.4 m

h = 960.4 m

A boy standing on the bridge kicks a stone into the water below. He kicks the stone with a horizontal velocity of 6.59 m/s. It lands in the water 10.92 m away from the bridge. How high is the bridge?

Answers

The stone travels a horizontal distance of

x = (6.59 m/s) * t

after time t. For the stone to have covered 10.92 m, it would have traveled for

10.92 m = (6.59 m/s) * t

t = (10.92 m) / (6.59 m/s)

t ≈ 1.66 s

The stone's altitude at time t is

y = h - g/2 * t²

where g = 9.80 m/s² is the acceleration due to gravity, and h is the height of the bridge. The stone reaches the ground after about 1.66 s, so at that point y = 0 and we solve for h :

0 = h - 1/2 * (9.80 m/s²) * (1.66 s)²

h = 1/2 * (9.80 m/s²) * (1.66 s)²

h13.5 m

D

TE=TM

Answers

The relationship between the two times is [tex]TE = TM\sqrt{\frac{gM}{gE} }[/tex]

The given parameters:

the acceleration due to gravity on the Moon = gM

height from which the object was dropped on moon, =  H

time taken for the object to reach the moon surface, = TM

height from which the object was dropped on Earth, =  H

the acceleration due to gravity on the Earth = gE

time taken for the object to reach the Earth's surface = TE

To find:

The relationship between the two times:

Apply the following kinematic equation:

[tex]H = ut + \frac{1}{2} gt^2\\\\we \ know \ nothing \ about \ the \ initial \ velocity \ u , let \ u = 0\\\\H = \frac{1}{2} gt^2\\\\[/tex]

Height equation for the object on the moon:

[tex]H = \frac{(gM) TM^2}{2}[/tex]

Height equation for the object on the Earth:

[tex]H = \frac{(gE) TE^2}{2}[/tex]

Since the two heights are equal, set the two equation to be equal to each other to determine the relationship between the two times:

[tex]\frac{(gE)TE^2}{2} = \frac{(gM)TM^2}{2} \\\\(gE)TE^2 = (gM)TM^2\\\\make \ TE \ the \ subject \ of \ the \ formula;\\\\ TE^2 = \frac{(gM)TM^2}{gE} \\\\TE= \sqrt{\frac{(gM)TM^2}{gE} } \\\\TE = TM\sqrt{\frac{gM}{gE} }[/tex]
