NOAA Scienctist

Explanation:

The stakeholder who expressed concern over the removal of the Bloede dam was the NOAA Scientist. So, option C.

A stakeholder is a person, group, or organization that has a vested interest in the choices made and the actions taken by a company, organization, or business initiative.

Here,

Stakeholders are important because, there wouldn't be any projects without them. The project can gain a lot from including its stakeholders.

They can participate in the decision-making process and have an impact on the organization's actions in a way that benefits the project management team.

The dismantling of Bloede Dam was long overdue given the environmental and safety concerns.

The difficulties caused by Bloede Dam are not unusual. Our nation's dams are increasingly hazardous to the environment and dangerous to people, with more than 90,000 dams blocking rivers around the country, including at least 659 in Maryland alone.

Hence,

The stakeholder who expressed concern over the removal of the Bloede dam was the NOAA Scientist. So, option C.

Answer:

Satellite D

Explanation:

It has more mass

Answer:

Explanation:

F = ma and

[tex]a=\frac{v}{t}[/tex]

We have F, we have m, but in order to solve for v, we need a.

30.0 = 3.00a so

a = 10.0 m/s/s. Plug that in for a in the second equation and solve for v:

[tex]10.0=\frac{v}{3.00}[/tex] so

v = 10.0(3.00) so

v = 30.0 m/s

Answer:

I. Weight = 490 Newton

II. Newton's Second Law of Motion

III. Force = 100 Newton

Explanation:

Given the following data;

Mass = 50 kg

Acceleration = 2 m/s²

I. To find the weight of the gymnast;

Weight = mass * acceleration due to gravity

We know that acceleration due to gravity is equal to 9.8 m/s².

Weight = 50 * 9.8

Weight = 490 Newton

II. Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] F = ma[/tex]

III. To find the force, we would use the following formula;

[tex] F = ma [/tex]

[tex] F = 50 * 2[/tex]

Force = 100 Newton

Answer:

Explanation:

Use the one-dimensional equation

[tex]v_f=v_0+at[/tex] where v is the final velocity, v0 is the initial velocity, a is the acceleration, and t is the time it takes to reach that final velocity. We are solving for t. Filling in the other values:

0 = 28 + (-6.4)t and

-28 = -6.4t so

t = 4.4 seconds

Answer:

Explanation:

We need 2 different equations for this problem: first the velocity of sound equation, then the frequency of the sound equation.

The velocity of sound is found in:

v = 331.5 + .606T

We need to find that first in order to fill it into the frequency equation which is

[tex]f=\frac{v}{\lambda}[/tex] where v is the velocity we will find the part a, f is frequency and lambda is the wavelength. Starting with the velocity of the sound:

v = 331.5 + .606(25) and

v = 331.5 + 15 and rounding correctly using the rules for sig fig when adding:

v = 347 m/s

Filling that into the frequency equation:

[tex]75=\frac{347}{\lambda}[/tex] and

[tex]\lambda=\frac{347}{75}[/tex] so

[tex]\lambda=4.6m[/tex]

Answer:

oxygen concentration

Explanation:

Answer:

Explanation:

this is a simple application of Newton's 2nd Law: F = ma.

F = .019(23) so

F = .44 N

You would need to apply a force of 0.437 Newtons to the ball in order to achieve the desired acceleration of 23 m/s².

Force is a physical quantity that describes the interaction between objects or systems and their ability to change motion or shape. It is a vector quantity, meaning it has both magnitude and direction. Force can cause an object to accelerate, decelerate, or change direction.

According to Newton's second law of motion, force is directly proportional to the mass of an object and the acceleration it experiences. The equation F = m × a represents this relationship, where F is the force, m is the mass of the object, and a is the acceleration.

Force can be measured in various units, such as Newtons (N) in the International System of Units (SI) or pounds (lb) in the US customary system. Common examples of forces include gravity, friction, tension, compression, and applied forces like pushing or pulling an object.

According to Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a):

F = m × a

In this case, the mass of the ball is given as 0.019 kg, and the desired acceleration is 23 m/s². Plugging these values into the equation, we can calculate the force:

F = 0.019 kg × 23 m/s²

F = 0.437 kg m/s²

Explanation:

An oven thermostat regulates the temperature inside an oven. The thermostat's temperature-sensitive probe measures the oven's warmth, switching the heat on and off as necessary to maintain the correct temperature.

Answer:

The answer is below

Explanation:

Given that the volume (V) = 0.4 m³, temperature difference (ΔT) = 270 K - 350 K = -80 K, pressure (P) = 60 kPa = 60000 Pa, R = 8.314 J/molK

Since we have constant volume, we can use the final state parameters to calculate the number of moles using the ideal gas law:

[tex]PV=nRT\\\\n=\frac{PV}{RT} =\frac{60000*0.4}{8.314*270} =10.69\ moles[/tex]

Given that the molar heat capacity at constant volume ([tex]C_v[/tex]) = 28.0 J/(mol K), the heat absorbed (Q) is:

[tex]Q=nC_v\Delta T=10.69*28*(-80) = -23945.6\ J\\\\Q=-23.95\ kJ[/tex]

Q ≈ -24 kJ

Answer:

its si unit is joule

Answer:

4.4 seconds

Explanation:

use the equation

v(final)=v(initial)+a(t)

what we know:

v(initial)=28mps

v(final)=0 because it comes to a stop

a= -6.4    it is negative because the 6.4 is resisting forward motion

using these you get

0= 28 + (-6.4)t

6.4(t)=28

t=4.375 sec

Your answer is 37.5 N

Explanation:

Force, F = BIL

F = 15 x 5 x 0.5 = 37.5 N

Answer:

72 N

Explanation:

Applying,

F = (m'+m)a..................... Equation 1

Where F = Force, m' = First mass, m = second mass, a = acceleration.

From the question,

m' = 2 kg, m = 4 kg, a = 12 m/s²

Substitute these values into equation 1

F = 12(2+4)

F = 12×6

F = 72 N
