What's scientific notation

Answer:

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.

Explanation:

The hydraulic system works on the principle of Pascal's law which says that the pressure in an enclosed fluid is uniform in all the directions. ... As the pressure is same in all the direction, the smaller piston feels a smaller force and a large piston feels a large force.

         The relationship between electric current and potential difference is stated by Ohm's law. Most conductors' current is directly inversely proportional to the voltage applied to them. German physicist Georg Simon Ohm was the first to empirically confirm Ohm's law.

The expression for Ohm's law is V I. As a result, V = RI, where R is the resistance constant. R is influenced by the conductor's material, size, and other factors. Ohm () is its SI unit.

      Ohms to volts conversion using the formula watts volts = watts ohms. or.

V = √W × Ω Example.

Given that,

  Voltage (v) = 250 V          

  Resistance (R) = 25 Ω,

   Determine current (I) =?

 We know that from ohm's law

 V = I R    

  I = V/R

  I = 250 / 25

  I = 10 A

Current in the circuit is 10 Amps.

multiplication of two vectors yields a vector oroduy

Answer:

a)   i₈ = 0.5 i₄,  b)   i₁₀ = 0.3 i₃,    i₁₀ = 0.8 i₈

Explanation:

For this exercise we use ohm's law

       V = i R

        i = V / R

we assume that the applied voltage is the same in all cases

let's find the current for each resistance

R = 4 Ω

         i₄ = V / 4

R = 8 Ω

         i₈ = V / 8

we look for the relationship between these two currents

         i₈ /i₄ = 4/8 = ½

         i₈ = 0.5 i₄

R = 3 Ω

        i₃ = V3

R = 10 Ω

        i₁₀ = V / 10

we look for relationships

       i₁₀ / 1₃ = 3/10

       i₁₀ = 0.3 i₃

       i₁₀ / 1₈ = 8/10

       i₁₀ = 0.8 i₈

          q / q₀ = 1 - e^{-t/  \tau }

in this exercise they indicate that

          q / q₀ = ½

for a time t = 25 10⁻³ s

we substitute

          ½ = 1 - [tex]e^{- 25 \ 10^{-3} / \tau}[/tex]

          e^{- 25 \ 10^{-3} /  \tau} =  1 -½

         - 25 10⁻³ /τ = ln 0.5

         -25 10⁻³ / ln 0.5 = τ

Answer:

The current through R2 is 0.078125 amperes.

Explanation:

Ohm's law is the relationship between electrical conductors and their resistance, which establishes that the current that passes through the conductors is proportional to the voltage applied to them.

Ohm's Law relates the magnitudes of voltage, resistance, and intensity as follows:

V=I*R

where V is the electric potential in volts, I is the current in amperes, and R is the resistance in ohms.

R1 has a 0.200 amperes current  flowing through it and a resistante of 25 ohms.

So:

V=0.200 amperes* 25 ohms

Solving:

V=5 volts

Now, for resistance R2 you know the value of the voltage (5 volts) and the value of its resistance R2 = 64 ohms. So:

5 volts= I* 64 ohms

Solving:

[tex]I=\frac{5 volts}{64 ohms}[/tex]

I= 0.078125 amperes

The current through R2 is 0.078125 amperes.

Answer:

the current through R₂ is 0.078 A

Explanation:

Given;

resistance of the first resistor, r₁ = 25 ohms

resistance of the second resistor, r₂ = 64 ohms

current through the first resistor, I₁ = 0.2 A

The voltage passing through each resistor is constant since they are connected parallel to each other.

V = I₁R₁ = I₂R₂

[tex]I_2 = \frac{I_1R_1}{R_2} \\\\I_2 = \frac{0.2 \times 25}{64} \\\\I_2 = 0.078 \ A[/tex]

Therefore, the current through R₂ is 0.078 A

Answer:

v = 6295.55 m/s

Explanation:

Given that,

The radius of a planet, [tex]r=5.32\times 10^6\ m[/tex]

The free fall acceleration of the planet, a = 7.45 m/s²

We need to find the tangential speed of a person standing at the equator.

Also, the centripetal acceleration was equal to the gravitational acceleration at the equator.

We know that,

Centri[etal acceleration,

[tex]a=\dfrac{v^2}{r}\\\\v=\sqrt{ar}\\\\v=\sqrt{5.32\times10^6\times 7.45}\\\\v=6295.55\ m/s[/tex]

So, the tangential speed of the person is equal to 6295.55 m/s.

Answer:

a. 86.80 m

b. i. The mass of the bob

ii. The length of the pendulum

Explanation:

a. Determine the height of the smokestack.

Using T = 2π√(L/g) where T = period of pendulum = 18.7 s, L = length of pendulum = height of smokestack and g = acceleration due to gravity = 9.8 m/s².

So, making L subject of the formula, we have

T = 2π√(L/g)

T/2π = √(L/g)

squaring both sides, we have

(T/2π)² = L/g

L = (T/2π)²g

Substituting the values of the variables into the equation, we have

L = (T/2π)²g

L = (18.7 s/2π)²(9.8 m/s²)

L = (2.976 s)²(9.8 m/s²)

L = 8.857 s² × 9.8 m/s²

L = 86.796 m

L ≅ 86.80 m
