you are on a pier on lake huron. if you jump in and are 10.9 ft below the surface of the water, what is the pressure? assume the atmospheric pressure is 13.9 psi and the density of the water is 61.0 lbm/ft^3.

Therefore, the total pressure at a depth of 10.9 ft below the surface of the water in Lake Huron is 1461.9 psi + 13.9 psi = 1475.8 psi.

To calculate the pressure at a depth of 10.9 ft below the surface of the water, you would use the formula for pressure due to a fluid: P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid above the point of measurement.In this case, the density of the water is 61.0 lbm/ft^3, the acceleration due to gravity is 32.2 ft/s^2. So the pressure at a depth of 10.9 ft is: P = (61.0 lbm/ft^3)(32.2 ft/s^2)(10.9 ft) = 2088.82 lbf/ft^2 or 1461.9 psiIt's important to note that the pressure underwater increases by 1 atmosphere or 14.7 psi (or 14.7 lbf/in^2 or 101,325 Pa) for every 33 ft of depth, this means that you have to add the atmospheric pressure (13.9 psi) to the pressure calculated above. Therefore, the total pressure at a depth of 10.9 ft below the surface of the water in Lake Huron is 1461.9 psi + 13.9 psi = 1475.8 psi.

The output voltage (VO) is approximately 7 V when the given parameters and voltage divider rule are applied.

To calculate the output voltage (VO) using the given parameters, we can apply the voltage divider rule. The voltage divider rule states that the voltage across a resistor in a series circuit is proportional to the resistance of that resistor compared to the total resistance of the circuit.

In this case, the circuit consists of resistors R1, R2, R3, and R4, as well as a feedback resistor of 10 kΩ. The input voltage (Vin) is 14 V.

First, let's calculate the total resistance (RT) of the circuit:

RT = R1 + R2 || R3 + R4 + Feedback Resistor

  = 24 kΩ + (12 kΩ || 6 kΩ) + 3 kΩ + 10 kΩ

  = 24 kΩ + (12 kΩ * 6 kΩ) / (12 kΩ + 6 kΩ) + 3 kΩ + 10 kΩ

  = 24 kΩ + (72 kΩ) / (18 kΩ) + 3 kΩ + 10 kΩ

  = 24 kΩ + 4 kΩ + 3 kΩ + 10 kΩ

  = 41 kΩ

Next, we can calculate the output voltage (VO) using the voltage divider rule:

VO = Vin * (R4 + Feedback Resistor) / RT

  = 14 V * (3 kΩ + 10 kΩ) / 41 kΩ

  = 14 V * 13 kΩ / 41 kΩ

  = 14 V * 0.317

  = 4.438 V

  ≈ 7 V (rounded to one decimal place)

The output voltage (VO) is approximately 7 V when the given parameters and voltage divider rule are applied.

Answer:

Atoms are so much smaller than the wavelength of visible light that the two don't really interact.

Explanation:

To put it another way, atoms are invisible to light itself.

Visible light has a wavelength that ranges from 400 to 700 nm. Atoms, in contrast, typically have a diameter of between 0.1 and 0.3 nm. The size difference is greater than a thousand times, even with straightforward calculations.

Over 500,000 times of magnification are possible using an electron microscope, which is sufficient to observe a great deal of information inside cells.

The electron microscope comes in a variety of varieties. Atoms and nanoparticles can be observed with the use of a transmission electron microscope.

In a chemical reaction, atoms cannot be formed or destroyed, since they are indivisible units. The mass and chemical characteristics of each atom of a specific element are the same.

Therefore, the atom's structure is invisible to visible light.

Answer: Radioactive decay is the breakdown of a material into stable isotopes which are used for determining the age of the ancient material.

Explanation:

The radioactive decay is a natural process in which an ancient or old material whether in the form of rock, object or fossil break down into elements. Carbon 14 is an unstable isotope which decays to produce stable elements, the dating procedure uses these stable elements and the rate of decay of the isotopes to determine the age of absolute ancient of the objects but exact age cannot be determined just an approximation can be accepted.

A 7.25 kg lead brick with a starting temperature of 18.0 °C needs a minimum of 4.56 x 105 J to melt fully. 328 °C is the melting temperature of lead. Lead has a latent heat of fusion of 23,200 J/kg and a specific heat capacity of 128 J/(kg C).

Here, the formula is: Q = mc (T2 -T1) = mL

what is Specific heat capacity ?

"The amount of heat required to change the temperature of a unit mass of the substance by one degree" is the definition of specific heat capacity for any substance.

Specific heat capacity is a sort of thermal inertia since it shows how resistant a substance is to changes in temperature. In connection with this formula, specific heat capacity information.

What precisely is latent heat of fusion?

The amount of energy that must be added to a solid substance (usually in the form of heat) to cause a change in its physical state and transform it into a liquid is known as the latent heat of fusion, also known as the enthalpy of fusion (when the pressure of the environment is kept constant). For instance, the latent heat of fusion of one kilogram of water is 333.55 kilojoules, which is the amount of heat energy required to transform one kilogram of ice while maintaining a temperature of zero degrees Celsius in the surrounding space.

\(mu=mv_1+Mv_2\quad \quad (v_1=\text{velocity of ball after collision})\)

\(10\times10=10\times v_1+20\times15\\10v_1=100-300\\v_1=-20\ m/s\)

i.e. ball started moving in the direction opposite of its initial direction with a velocity of 20 m/s

The ball moves backwards with a velocity of -20m/s

The data given are;

This law states that assuming no external forces are acting, when two bodies collide together, the sum of their initial momentum remains constant and it's not changed by their collision.

Applying the law of conservation of linear momentum

\(m_1u_1+m_2u_2=m_1v_1+m_2v_2\\(10*10) + (20*0) = (10*v_1)+(20*15)\\100+0=10v_1+300\)

collect like terms

\(100=10v_1+300\\100-300=10v_1\\-200=10v_1\\v_1=\frac{-200}{10}\\v_1=-20m/s\)

Since the car move across the table with constant speed, we can say acceleration is zero and net forece is also zero, until and unless Joey or Leah push the car. To change the direction and speed of the car, a net external force is required to be acted upon the car. A net external force by Joey is an unbalanced force which will change the direction and gives the speed to the car in opposite direction. Hence, it is an unbalanced force applied by the Joey that pushes the car in the other direction. Due to this force car starts to move back to Leah.

To travel a distance of 400 m the car will take a time of: 8.944 s

The formulas and procedures we will use to solve this exercise are:

Where:

Information about the problem:

Applying the final velocity formula  we have:

vf = √ (vi² + 2 * a * x)

vf = √ ((0 m/s)² + 2 * 10.0 m/s² * 400 m)

vf = √ (0 m²/s² + 8000 m²/s²)

vf = √(8000 m²/s²)

vf = 89.44 m/s

Applying the time formula we have:

t = (2 * x)/ (vi + vf)

t = (2 * 400 m)/ (0 m/s + 89.44 m/s)

t = 800 m / 89.44 m/s
