The Floridan aquifer system's approximate Velocity flow rate in this area

1. in feet/hour - 440 feet/hour

2. in miles/hour - 0.083 miles/hour

3. in meters/hour - 134.11 meters/hour

According to the computer display:

1 mile on the ground equals 1.2 cm on the map.

Distance between Blue sinks (as marked by you) and Sulphur springs = 2.8 cm

Then, 2.8 cm on the map = (1/1.2)*2.8 miles = 2.33 miles

Now,  

The velocity of flow in Floridan Aquifer = distance/time = 2.33 miles/ 28 hours = 0.083 miles per hour

Velocity in feet per hour = 0.083*5280 feet/hour = 440 feet/hour

The flow rate of the faucet is 127.23 cm²/s and diameter below the faucet is 1.88 cm.

For calculating the flow rate, we will use the formula -

Q = Ar

A = πr², were Q is flow rate, A is area and r is radius.

Also, radius = diameter/2

Radius = 1.8/2

Radius = 0.9 cm

Speed = 50 cm/s

Q = πr²v

Q = 3.14×0.9²×50

Q = 127.23 cm²/s

The diameter of stream will be calculated by the formula -

[tex] v_{f}[/tex]² - [tex] v_{i}[/tex]² = 2gy, where [tex] v_{f}[/tex] is final velocity, [tex] v_{f}[/tex] is initial velocity, g is acceleration due to gravity and y is diameter of stream.

[tex] v_{f}[/tex] = ✓2500 - 392

[tex] v_{f}[/tex] = ✓2108

[tex] v_{f}[/tex] = 45.9 cm/s

r = ✓Q/πv

r = ✓127.23/3.14 × 45.9

r = ✓127.23/144.2

The nuclear fusion reaction occurs at temperatures approximately 107 degrees Celsius. It takes this high temperature for the nuclei to begin travelling at high speeds, increasing their kinetic energy.

Nuclear fusion is a nuclear reaction that occurs when two light nuclei collide to form a single, heavier nucleus. Because the mass of the new nucleus is smaller than the sum of the original masses, fusion releases energy. According to the concept of mass-energy equivalence, this mass difference indicates that some of the "lost" mass has been turned into energy. Fusion necessitates both extremely high temperatures in order to provide enough energy to hydrogen atoms to overcome proton repulsion.

To find the change in temperature of the strut, we need to use the equation for the heat capacity of a solid:

q = C * m * ΔT

Where q is the amount of thermal energy absorbed by the strut, C is the specific heat capacity of steel, m is the mass of the strut, and ΔT is the change in temperature of the strut. Substituting the given values into the equation, we get:

2.50 105 j = 0.47 J/g*C * 1.67 kg * ΔT

Solving for ΔT, we get:

ΔT = (2.50 105 j) / (0.47 J/gC * 1.67 kg) = 461.37 gC

The change in temperature of the strut is 461.37 g*C.

To find the expansion of the strut due to the absorption of thermal energy, we need to use the equation for thermal expansion:

ΔL = L * α * ΔT

Where ΔL is the change in length of the strut, L is the original length of the strut, α is the coefficient of thermal expansion of steel, and ΔT is the change in temperature of the strut. Substituting the given values into the equation, we get:

ΔL = 1.90 m * 1.2 10-5/C * 461.37 g*C = 0.0011 m

The expansion of the strut due to the absorption of thermal energy is 0.0011 m.

To find the compressive stress on the strut, we need to use the equation for stress:

σ = F / A

Where σ is the compressive stress on the strut, F is the compressive force on the strut, and A is the cross-sectional area of the strut. Since the strut is attached at both ends and is not allowed to move, the compressive force on the strut is equal to the force due to the thermal expansion of the strut:

F = k * ΔL

Where k is the spring constant of the strut, which is determined by the stiffness of the strut and its attachment points. Substituting this expression for F into the equation for stress, we get:

σ = (k * ΔL) / A

Substituting the given values into the equation, we get:

σ = (k * 0.0011 m) / (1.00 10-4 m2) = 11.00 kN/m2

The compressive stress on the strut is 11.00 kN/m2.

The smallest expansion of a substance due to the absorption of a given amount of thermal energy will occur when the substance has a small specific heat capacity and a small coefficient of thermal expansion.

This is because a small specific heat capacity means that the substance requires less thermal energy to raise its temperature by a given amount, and a small coefficient of thermal expansion means that the substance will experience less expansion per unit increase in temperature.

What is velocity?

A body's or an object's motion's direction. Speed is fundamentally a scalar quantity. Velocity is a vector quantity in its purest form. It refers to the rate at which distance varies. It is the rate of displacement change.

What is height?

Height is a measurement of vertical distance, or how high something or someone is (how tall they are) (how "high" a point is).

The range ( X) of cannon ball is equal to height (h) of the cliff, which is initial height of cannon ball.

∴ X= h

Therefore, the angle which final velocity vector of the cannon ball makes with and below horizontal is given by

On the ground, there is a known separation between the telescopes. As a result, the radio waves from the source will reach each telescope at a little different time. The waves appear slightly differently, with one arriving a little bit later than the other. The difference is a shift in the wave's phase over time.

Due to their phase shift, the two offset waves will not precisely overlap when combined, leading to interference fringes. The angles of their observations shift as the Earth rotates and the telescopes tilt to continue monitoring their source setting.

Similar to how shadows are longer when the Sun is lower, this tracking movement of the telescopes alters the distances that radio light travels from the source to each telescope.
