A research historian is interested in finding a sunken treasure in the Atlantic Ocean. She knows that her equipment is only good enough to recover items that are at a depth of 5 000 m or less. The speed of sound through the water is 1 530 m/s. While working, the sonar equipment detects a reflection that is of interest. The echo from the item takes 6.2 s to return to the sonar detector. Will she be able to retrieve this item?

Answers

Yes, she will be able to retrieve the item

An echo is the repetition of sound formed due to the reflection of the sound wave.

From the question, we are given the following;

Speed of sound through water v = 530m/s

The time it takes the echo to reach the sonar detector t = 6.2s

First, we need to know how far the echo can travel using the formula;

2x = vt

x is the distance from the source of the sound to the reflector

v is the speed of sound

t is the time

Substituting the given values into the formula:

[tex]x=\frac{vt}{2}\\x=\frac{530*6.2}{2} \\x=530*3.1\\x= 1643m[/tex]

Since the research historian knows that her equipment is only good enough to recover items that are at a depth of 5 000 m or less and 1643m is less than 5000m, hence she will be able to retrieve the item.

Learn more about echo here: https://brainly.com/question/23127522

The research historian can retrieve the item.

Sound is a form of mechanical waves, which is a kind of waves that needs a medium to propagate itself and whose kinematic is representative of motion at constant speed. The maximum echo time ([tex]t_{e}[/tex]), in seconds, is the distance travelled by waves ([tex]s[/tex]), in meters, divided by velocity of sound through the medium ([tex]v_{s}[/tex]), in meters per second:

[tex]t_{e} = \frac{s}{v_{s}}[/tex] (1)

Please notice that distance travelled by sound is twice the depth of the sunken object.

If we know that [tex]s = 10000\,m[/tex] and [tex]v_{s} = 1530\,\frac{m}{s}[/tex], then the maximum echo time is:

[tex]t_{e} = \frac{10000\,m}{1530\,\frac{m}{s} }[/tex]

[tex]t_{e} = 6.535\,s[/tex]

Any sunken object whose echo time is less than 6.535 seconds can be retrieved. As the echo time related to the item was 6.2 seconds, the research historian can be able to retrieve the object.

How is the mass defect determined? A. The mass defect is determined by measuring the mass of emitted alpha particles B. The parent nuclear mass is divided by the daughter nuclear mass. C. The mass of a nucleus is subtracted from the mass of its components. OD. The loss of mass of a nucleus is determined by looking at its line spectrum.​

Answers

Answer:

C. The mass of a nucleus is subtracted from the mass of its components.

Explanation:

The difference in the mass of a stable nucleus and the combined masses of its constituents (i.e. nucleons) is called “Mass Defect” or “Mass Deficit”. It is denoted by Δm.

Symbolically,

[tex]\Delta m = (Zm_p+Nm_n)-m[/tex]

where,

Δm = mass defect

Z = Atomic Number

[tex]m_p[/tex] = mass of Proton

N = Neutron Number

[tex]m_n[/tex] = mass of Neutron

m = mass of Nucleus

Hence, the correct option is:

C. The mass of a nucleus is subtracted from the mass of its components.

A man is running on the straight road with the uniform velocity of 3m/s. Calculate acceleration.​

Answers

Answer:

Answer is zero

Explanation:

Acceleration is defined as the rate of change in velocity. If there’s no change in velocity, then the rate of change is zero, hence the acceleration is zero. The question says the man is running at a uniform velocity (i.e. he’s running at a steady speed in a fixed direction). This means his velocity is constant, or unchanging. Hence, his acceleration is zero.

Statement:

A man is running on the straight road with the uniform velocity of 3 m/s.

To find out:

Acceleration produced by the man.

Solution:Given, the man is running with uniform velocity of 3 m/s.So the velocity did not change.It remains constant.We know, acceleration is the change of velocity per unit time.Since there is no change in velocity in this case, so there will be no acceleration.So, the acceleration produced by the man is zero.Answer:The acceleration produced by the man is zero.

how can you say that joule and Newton are derived units​

Answers

Answer:

F = M a    where M is acceleration and a is acceleration

a = x / s^2 = distance / time squared

The Newton is derived because mass, distance, and time are all fundamental units One would have to look at the fundamental requirements for these definitions, but they can all be repeated in a laboratory.

So the Newton is determined from these fundamental units and since the Joule equals Newton * Distance it is also derived from the fundamental units.

If one has the three fundamental units then one can derive the Joule and Newton.

1. How much heat energy ( Q ) is required to heat 2.0 kg of copper from 30.0 oC to 80.0 oC?

Answers

Answer:

Heat capacity, Q = 38500 Joules

Explanation:

Given the following data;

Mass = 2 kg

Initial temperature, T1 = 30°C

Final temperature, T2 = 80°C

Specific heat capacity of copper = 385 J/Kg°C

To find the quantity of heat required;

Mathematically, heat capacity is given by the formula;

[tex] Q = mcdt [/tex]

Where;

Q represents the heat capacity or quantity of heat.

M represents the mass of an object.

C represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 80 - 30

dt = 50°C

Substituting the values into the formula, we have;

[tex] Q = 2 * 385*50[/tex]

Heat capacity, Q = 38500 Joules

a ball is kicked and follows a parabolic trajectory. in mid flight, what is the net horizontal force of the ball?

Answers

Answer:

The net horizontal force is zero.

Explanation:

When an object is in the air, the primary force acting on the object will be the gravitational force, which pulls the object down to the ground.

There is also air resistance, a force that depends on the shape and velocity of the object, and can be ignored.

So, once the ball is already kicked and is in the air, the only force acting on the ball will be the gravitational force, which is a vertical force.

Thus, there is not a horizontal force.

Then the net horizontal force is zero, if we are ignoring the air resistance.

• A car is initially traveling at 50.0 km/h. The brakes are applied and
the car stops over a distance of 35 m. What was magnitude of the
car's acceleration while it was braking?

Answers

Answer:

Explanation:

The equation for acceleration is

[tex]a=\frac{v_f-v_0}{t}[/tex] where vf is final velocity, v0 is initial velocity and t is time in seconds. But we have a problem here because the initial velocity is given in km/hr while the distance is given in meters. We are going to change 50.0 km/hr to m/sec:

[tex]50\frac{km}{y\hr}*\frac{1000m}{1km}*\frac{1hr}{3600s}[/tex] which gives us an initial velocity of

v = 13.9 m/s

But that still doesn't give us anything for the time, which is the denominator of the acceleration equation. We have to find it. Since this is one-dimensional travel, use d = rt to find the time it took for the car to travel 35 meters at a rate of 13.9 m/s:

35 = 13.9t and

t = 2.5 seconds. Now we can use that in the acceleration equation:

[tex]a=\frac{0-13.9}{2.5}[/tex] so

a = -5.6 m/s/s The negative sign tells us that the car is slowing down, as we would expect it to be when it is traveling at a certain rate and eventually stops.

M1=1kg,m2=2kg,khi chuyển động cùng chiều có vận tốc lần lượt là v1=5m/s và v2 =6m/s động lượng của 2 vật bằng

Answers

Answer:

Total momentum is 17 kg m/s.

Explanation:

M1 = 1 kg, m2 = 2 kg, when moving in the same direction with speeds v1 = 5 m/s and v2 = 6 m/s, the momentum of the two bodies is equal to

The momentum is defined as the product of mass and the velocity of body.

Momentum of first body. p' = M1 v1 = 1 x 5 = 5 kg m/s

Momentum of second body, p'' = M2 v2 = 2 x 6 = 12 kg m/s

As they both are moving in the same direction so the net momentum is

p = p' + p''

p = 5 + 12 = 17 kg m/s

B. James does some of his coworkers' work because he wants to be popular.

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.

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

Given that,

Magnetic force acting on an electron, [tex]F=12.8\times 10^{-19}\ N[/tex]

The magnitude of the magnetic field,[tex]B=8\times 10^{-5}\ T[/tex]

We need to find the magnitude of the velocity. We know that the magnetic force is given by :

[tex]F=qvB[/tex]

Where

v is the velocity

So,

[tex]v=\dfrac{F}{qB}\\\\v=\dfrac{12.8\times 10^{-19}}{1.6\times 10^{-19}\times 8\times 10^{-5}}\\\\v=10^5\ m/s[/tex]

So, the magnitude of velocity is[tex]10^5\ m/s[/tex].
