determine the metacentric height of a cylinder of 4 m diameter and height of 4m floating in water with its axis vertical, if period of oscillation is 6 seconds

Answers

Answer:

-0.383 m

Explanation:

Diameter of cylinder = 4m  therefore  r = 2

height of cylinder ( H ) = 4 m

specific gravity = 0.6 ( assumed )

depth of immersion = 'h'

Determine the metacentric height

weight of cylinder in water = water displaced

= 0.6 * 1000 * πr^2* H = 1000 * πr^2* h

= 0.6 * 4 = h

∴ h = 2.4 m

hence the depth of center of buoyancy from free space = h /2 = 1.2 m

The metacentric height can be calculated using the formula below

Gm = Io / Vsubmerged  - BG

attached below is the remaining solution

A convex mirror of radius of curvature 1.6 m has an object placed at a distance of 1.0 m from it. Find the position of image and the magnification.​

Answers

Answer:

The image is formed at 0.44 m in front of the mirror

magnification (M) = 0.44

Explanation:

Applying, mirror formular

1/f = (1/u)+(1/v).................... Equation 1

Where f = Focal length of the convex mirror, u = object distance, v = image distance.

Using the real is positive convection,

From the question,

Given: f = -1.6/2 = -0.8 m( The focal length of a convex mirror is vitual), u = 1.0 m

Substitute these values into equation 1

-1/0.8 = (1/v)+(1/1)

Solve for v

1/v = 1.25+1

1/v = 2.25

v = 1/2.25

v = 0.44 m

Hence the image is formed at 0.44 m in front of the mirror

Magnification (M) = v/u

m = 0.44/1

m = 0.44

Cuando una persona sube y baja una escalera, Cuanto vale su desplazamiento y cual es la medida de su trayectoria.

Answers

Answer:

Primero, definimos el desplazamiento como la distancia entre la posición final y la posición inicial.

Así, si comenzamos abajo, luego subimos la escalera, y luego bajamos, la posición final y la posición inicial serán la misma

por lo que el desplazamiento es igual a cero.

La medida recorrida es el espacio total recorrido.

Es decir, si entre el principio y el final de la escalera hay una distancia D.

La persona que sube y baja, recorre esta distancia dos veces.

Entonces cuando una persona sube y baja la escalera, la medida de su trayectoria será 2*D.

A train covers 450 km in 5 hr. between Station A and Station B.
What is the average speed of train in km/h and m/s.

Answers

Answer:

90 km/h

50 m/s

Explanation:

Distance = 450 km

Time = 5hrs

Speed = Distance/Time

450/5 = 90 km/h

1 km = 1,000 m

1 hr = 60m = 60 x 60 = 3,600 sec

but since it's 5hrs = 60 x 300m = 18,000

90 x 1,000 = 90,000/18,000 = 50 m/s

An upright image which reduced in size 10 times occurred in a mirror. If the radius of
curvature of the mirror is 2 m, bow far is the object from the mirror?​

Answers

Answer:

-10/9 m

Explanation:

Radius of curvature, R=2 m

Focal length of mirror, f=R/2=2/2=1 m

Let height of object=h

Height of image, h'=h-10h=-9h

We have to find the distance of object from the mirror.

Magnification, m= [tex]\frac{h'}{h}=-\frac{v}{u}[/tex]

[tex]m=\frac{-9h}{h}=-9[/tex]

Image is upright and small in size it means the mirror is convex.

Focal length of convex mirror is negative.

f=-1m

[tex]-9=-\frac{v}{u}[/tex]

[tex]v=9u[/tex]

Now, mirror formula

[tex]\frac{1}{v}+\frac{1}{u}=-\frac{1}{f}[/tex]

[tex]\frac{1}{9u}+\frac{1}{u}=\frac{1}{1}[/tex]

[tex]\frac{1+9}{9u}=-1[/tex]

[tex]10=-9u[/tex]

[tex]u=-\frac{10}{9} m[/tex]

Hence, the distance of object  from the mirror is -10/9 m

Solve this question for 5 points

Answers

Answer:

M_b = 2M_a

Explanation:

From gravity equation, we know that;

g = GM/R²

Where;

g is acceleration due to gravity

G is the gravitational constant

M is mass

Thus, making mass(M) the subject, we have;

M = gR²/G

Since we want to find the mass of B so that value of g on B is half that of its value on A.

Thus;

> g_b = ½g_a

> g_b/g_a = ½

Also, we are told that;

> R_a = ½R_b

> R_b/R_a = 2

If M_a = g_a•R_a²/G

And M_b = g_b•R_b²/G

Thus;

M_b/M_a = (g_b•R_b²/G)/(g_a•R_a²/G)

G will cancel out to give;

M_b/M_a = (g_b•R_b²)/(g_a•R_a²)

Rearranging for ease of simplification, we have;

M_b/M_a = (g_b/g_a) × (R_b/R_a)²

Plugging in the relevant ratios gives;

M_b/M_a = ½ × 2²

M_b/M_a = 2

M_b = 2M_a

If the mass of the Jupiter is 1.9*10 kg and radius is fbx loom what is acclerallon due to gravity on the supiter ?​

Answers

Answer:

Explanation:

Given that,

The mass of the Jupiter,[tex]M=1.9\times 10^{27}\ kg[/tex]

The radius of Jupiter,[tex]r=69,911\ km=69911\times 10^3 km[/tex]

We need to find the acceleration due to gravity on Jupiter. The formula is

[tex]g=G\dfrac{M}{r^2}[/tex]

Put all the values,

[tex]g=6.67\times 10^{-11}\times \dfrac{1.9\times 10^{27}}{(69911\times 10^3)^2}\\\\g=25.92\ m/s^2[/tex]

The Indianapolis speedway consists of a 2.5 mile track having four turns, each 0.25 mile long and banked at 9 12'

Answers

Answer: Your question is missing below is the question

Question : What is the no-friction needed speed (in m/s ) for these turns?

answer:

20.1 m/s

Explanation:

2.5 mile track

number of turns = 4

length of each turn = 0.25 mile

banked at 9 12'

Determine the no-friction needed speed

First step : calculate the value of R

2πR / 4 =  πR / 2

note : πR / 2 = 0.25 mile

∴ R = ( 0.25 * 2 ) / π

      = 0.159 mile ≈ 256 m

Finally no-friction needed speed

tan θ = v^2 / gR

∴ v^2 = gR * tan θ

 v = √9.81 * 256 * tan(9.2°)  = 20.1 m/s

C. James accepts additional tasks at work as a way to show he can handle greater responsibility.

D. James turns down additional tasks at work because he doesn't want more responsibility.

Answer:

C. James accepts additional tasks at work as a way to show he can handle greater responsibility.

Explanation:

An employee can be defined as an individual who is employed by an employer of labor to perform specific tasks, duties or functions in an organization.

Basically, an employee is saddled with the responsibility of providing specific services to the organization or company where he is currently employed while being paid a certain amount of money hourly, daily, weekly, or monthly depending on the contractual agreement between the two parties (employer and employee).

A productive employee is a kind of person that is highly effective and efficient in the performance of his or her duties, especially through the use of their skills, knowledge, competence and expertise (experience). Also, a positive attitude or attribute are ethical and morally right characteristics  (qualities) that a person exhibits.

Typically, there exist a strong relationship between a positive attitude and the level of productivity of an employee.

Hence, an example of the correlation of productivity and a positive attitude would be James accepting additional tasks at work as a way to show he can handle greater responsibility. Thus, he is more focused on challenging himself to handle greater responsibility by accepting additional tasks at his work place.
