A 2 kg hammer is used to nail a 0.002 kg nail with a force of 10 N. How much force is applied to the hammer?
Answer:
10 N
Explanation:
Given that,
A 2 kg hammer is used to nail a 0.002 kg nail with a force of 10 N.
We need to find how much force is applied to the hammer.
We know that, every action has an equal and opposite reaction. Both the action and reaction occurs in two different objects.
Hence, the force applied to the hammer is equal to 10 N.
You hear a tone and recognized it to me 512 Hz and you know that the speed of sound
is 340 m/s at the surface of the earth. What is the wavelength of the sound?
Answer with three significant figures.
Answer:
Explanation:
The frequency equation is
[tex]f=\frac{v}{\lambda}[/tex] where f is frequency measured in Hz, v is velocity of sound measured in m/s and [tex]\lambda[/tex] is wavelength measured in meters. Filling in our given info:
[tex]512=\frac{340}{\lambda}[/tex] and
[tex]\lambda=\frac{340}{512}[/tex] so
[tex]\lambda=.664 m[/tex] (That is the incorrect number of sig dig's by the way. It should only be 2 since the number 340 only has 2 sig dig's)
100 J OF HEAT IS PRODUCED EACH SECOND IN A 4 COULUMB RESISTER. THE POTENTIAL DIFFERANCE ACROSS THE RESISTER WILL BE
Answer:
The correct answer is "20 Volts".
Explanation:
Given:
Heat,
H = 100 J
Resistance,
R = 4 Ω
As we know,
⇒ [tex]P=\frac{v^2}{R}[/tex]
By putting the values, we get
⇒ [tex]100=\frac{v^2}{4}[/tex]
⇒ [tex]v^2=100\times 4[/tex]
⇒ [tex]=400[/tex]
⇒ [tex]v=\sqrt{400}[/tex]
⇒ [tex]=20 \ volts[/tex]
Si un movil parte del reposo logrando una aceleracion de 5 metros por segundo al cuadrado durante 8 segundos calcular la velocidad final
Answer:
Velocidad final, V = 40 m/s
Explanation:
Dados los siguientes datos;
Aceleración = 5 m/s²
Velocidad inicial = 0 m/s (ya que comienza desde el reposo)
Tiempo = 8 segundos
Para encontrar la velocidad final, usaríamos la primera ecuación de movimiento;
[tex] V = U + at[/tex]
Dónde;
V es la velocidad final. U es la velocidad inicial. a es la aceleración. t es el tiempo medido en segundos.Sustituyendo en la fórmula, tenemos;
[tex] V = 0 + 5*8 [/tex]
[tex] V = 0 + 40 [/tex]
[tex] V = 40 [/tex]
Velocidad final, V = 40 m/s

Which of the following stakeholders (who) expressed concern over the removal of the Bloede dam?
A Park Ranger
B Historian
C NOAA Scientist
Answer:
NOAA Scienctist
Explanation:
The stakeholder who expressed concern over the removal of the Bloede dam was the NOAA Scientist. So, option C.
What is meant by stakeholders ?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.

Una persona pesa 700 N al nivel del mar. ¿Cuándo sube a un avión a
10000 m de altura pesará más, igual o menos? Bien explicado por favor
Answer:
The weight of the person decreases.
Explanation:
Weight of person at sea level = 700 N
height = 10000m
We know that the weight is given by product of mass and the acceleration due to gravity.
The acceleration due to gravity at height is given by
[tex]g' =g\times \left ( \frac{R}{R+h} \right )^2[/tex]
Where, R is the radius of earth and h is the height.
Now, as we go on heights , the acceleration due to gravity decreases, so the weight also decreases as we go on heights.
Una mochila tiene una masa de 5.9 Kg y se mueve con una aceleración de: 0.53 m/ seg2. ¿ Cuál es la fuerza que debe aplicar ?.
Answer:
3,13 N
Explanation:
Del enunciado de la segunda ley del movimiento de Newton;
F = ma
Dónde;
F = Fuerza aplicada
m = masa del cuerpo
a = aceleración del cuerpo
Sustitución de valores;
F = 5,9 kg * 0,53 m / seg2 = 3,13 N
Por tanto, la fuerza aplicada es 3,13 N

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
how do i get a negative cube when i calculate density
Answer:
density should always be positive, you must have missed a sign somewhere

If the rotation of a planet of radius 5.32 × 106 m and free-fall acceleration 7.45 m/s 2 increased to the point that the centripetal acceleration was equal to the gravitational acceleration at the equator, what would be the tangential speed of a person standing at the equator?
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.

Two resistors, R1 = 25.0 ohms and
R2 = 64.0 ohms, are connected in
parallel. R1 has a 0.200 A current
flowing through it. What is the current
through R2?
Domomhor resistors in norollal
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

A 2kg mass and a 4kg mass on a horizontal frictionless surface are connected by a massless string A. They are pulled horizontally across the surface by a second string B with a constant acceleration of 12 m/s^2. What is the magnitude of the force of string B on the 2kg mass?
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

A certain capacitor, in series with a resistor, is being charged. At the end of 25 ms its charge is half the final value. The time constant for the process is about:
Answer:
τ = 36 10⁻³ s
Explanation:
The charge of a circuit Rc is given by the expression
q = q₀ (1 - [tex]e^{-t/ \tau }[/tex])
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
τ = 36 10⁻³ s
