The next step is to calculate the flood recurrence intervals and rank flood events by their maximum discharge and their recurrence intervals. From this data, it is possible to calculate the probability of the flood recurring. Table 1 (page 7) lists nine years of maximum daily streamflow stage (cfs) for the Big Thompson River. (6 pts)
In the third column, rank this data by year from the largest amount (rank of 1) to the smallest (rank of 9).
In the fourth column, calculate the probability, in percent, of the flood recurring using the formula:
rank/( n + 1 ) × 100 ; where n = the number of years with available data
In column five, rank the recurrence intervals. This is determined by the following equation:
RI = (N + 1)/M
Where: RI = the recurrence interval
N is the number of years the floods are on record
M is the rank of the flooding event (largest flood M = 1)
Because there are nine year

Answer:

Neptune's atmosphere is made up predominately of hydrogen and helium, with some methane. The methane is part of what gives Neptune its brilliant blue tint, as it absorbs red light and reflects bluer colors. Uranus also has methane in its atmosphere, but has a duller shading.

Explanation:

The low temperatures of these distant planets allow for the formation of methane clouds that contribute to the blue color.

The electric potential energy of the three quarks is equal to the product of the charges of the quarks divided by 200, multiplied by the constant \(\frac{1}{4\pi\epsilon_0}\).

Potential energy is a kind of energy that depends on the relative positions of different system components.

The electric potential energy of three quarks with a separation distance of 200 m is given by the equation

\(U = \frac{1}{4\pi\epsilon_0} \frac{q_1q_2}{r}\)

where \(q_1\) and \(q_2\) are the charges of the quarks and r is the distance between them.

In this case, since all three quarks have the same distance, r is 200 m, and the electric potential energy is calculated as:

\(U = \frac{1}{4\pi\epsilon_0} \frac{q_1q_2}{200}\)

Although both Harry and Sue cycle at the same speed, the tires on Sue's bike will have a greater rotational speed due to their smaller diameter.

The rotational speed of a tire is determined by the number of rotations it completes in a given time. It is directly related to the distance traveled by a point on the tire's circumference.

Since Harry and Sue cycle at the same speed, their linear speeds (or the speeds at which they move forward) are equal. However, the tires on Harry's bike have a larger diameter than those on Sue's bike.

The rotational speed of a tire is inversely proportional to its diameter. A larger diameter tire covers more distance with each rotation compared to a smaller diameter tire.

Therefore, the tires on Sue's bike will have a greater rotational speed. This means that for every rotation of Sue's smaller diameter tires, a point on the circumference will cover a shorter distance compared to Harry's larger diameter tires.

Consequently, Sue's tires will rotate more times in the same amount of time compared to Harry's tires.

The average horizontal component of the force that the ground exerts on the runner’s shoes is 167N. and The work done on the particle system is 2500 J. So, the internal energy decreases by 2500 J.

Mass of the runner = m = 50 kg

Initial velocity = u = 0 m/s

Final velocity = v = 10 m/s

Time taken = t = 3 s

Acceleration, a = (v - u) / t= (10 - 0) / 3= 3.33 m/s²

Horizontal force = ma= 50 kg × 3.33 m/s²= 167 N

The average horizontal component of the force that the ground exerts on the runner’s shoes is 167N.b) There is no work done on the extended system due to zero displacement and the work done on the particle system is 2500 J.

Work done = Force x Displacement

But in this case, no displacement takes place because the runner doesn't move in the horizontal direction. So, work done on the extended system is zero.

Work done by the force, W = change in kinetic energy

W = (1/2)mv² - (1/2)mu²

Here, initial velocity, u = 0 m/s

Final velocity, v = 10 m/s

Mass, m = 50 kg.

W = (1/2) × 50 × (10)²= 2500 J

The work done on the point particle system by this force is 2500 J. c)

The increase in the kinetic energy of the runner is due to the work done by the ground. So, the kinetic energy increases at the expense of some other form of energy. By doing work, some internal energy gets dissipated due to friction. So, there is a decrease in the internal energy.

Therefore, The work done on the particle system is 2500 J. So, the internal energy decreases by 2500 J. The work done on the particle system is 2500 J. So, the internal energy decreases by 2500 J. and The average horizontal component of the force that the ground exerts on the runner’s shoes is 167N.

A). To move the bar to the right with a constant speed of 6.00 m/s, we need to find the force required. The force required is the force of the magnetic field that acts on the bar. The power dissipated in the resistor is 6.98 W.

This force is given by the formula: F = BILsinθwhere,F is the force B is the magnetic field I is the current L is the length of the conductorθ is the angle between the magnetic field and the current direction Now, the current in the bar is given by: I = V/R where, V is the voltage applied across the resistor R is the resistance of the resistor Given, V = BLV/Rsinθwhere,L = 1.6 m B = 2.20 T, and R = 4.00 ?θ = 90° = π/2 radians So, V = 2.20 × 1.6 × 6.00/4.00  = 5.28 V The current in the circuit is, I = V/R = 5.28/4.00 = 1.32 A  

Therefore, the force required is: F = BILsinθ = 2.20 × 1.6 × 1.32 × 1 = 4.3872 N(b) The power dissipated in the resistor is given by: P = VI where, V is the voltage applied across the resistor I is the current in the circuit From the above calculations, V = 5.28 VI = 1.32 AP = VI = 5.28 × 1.32 = 6.98 W

d = ut + 0.5 at^2

v^2 = u^2 + 2 ad

initial velocity u = 25 m/s

acceleration a = - 1 m/s^2

V is equal to zero in the end.

Diabetes mellitus is characterized by glucose in the urine, excess urine production, and dehydration. The answer is (d).

Diabetes mellitus is a chronic disease that affects how your body turns food into energy. When you have diabetes, your body either doesn't make enough insulin or can't use the insulin it makes as well as it should.

Insulin is a hormone that helps move glucose from the bloodstream into the cells of the body to be used for energy. Without enough insulin, glucose builds up in the bloodstream, causing high blood sugar.

Diabetes mellitus is characterized by all of the following:

Glucose in the urine. When blood sugar levels are high, the kidneys can't reabsorb all of the glucose in the urine. This results in glucose being passed into the urine.

Excess urine production. When there is glucose in the urine, it draws water with it, causing excess urine production.

Dehydration. Excess urine production can lead to dehydration.

Increased thirst. Dehydration can lead to increased thirst.

Answer:

We can use the impulse-momentum theorem to solve this problem, which states that the change in momentum of an object is equal to the impulse applied to it. The impulse is given by the area under the force vs. time graph, which is shown in the figure.

First, we need to find the initial momentum of the car. Since the car is moving only in the x-direction, we can use the equation:

p_initial = m*v_initial

where p_initial is the initial momentum, m is the mass of the car, and v_initial is the initial velocity of the car. Plugging in the given values, we get:

p_initial = (0.250 kg)(0.860 m/s) = 0.215 kgm/s

Next, we need to find the change in momentum of the car, which is equal to the area under the force vs. time graph. We can approximate this area by dividing it into two triangles and a rectangle, as shown in the figure. The total area can be found as follows:

area = (1/2)(20 N)(0.002 s) + (20 N)(0.004 s) + (1/2)(10 N)(0.002 s)

= 0.06 Ns

Finally, we can use the impulse-momentum theorem to find the final momentum of the car, which is given by:

p_final = p_initial + impulse

where impulse is the area under the force vs. time graph. Plugging in the values, we get:

p_final = 0.215 kgm/s + 0.06 Ns = 0.275 kg*m/s

Since the mass of the car doesn't change during the collision, we can use the equation for momentum to find the final velocity of the car:

p_final = m*v_final

Solving for v_final, we get:

v_final = p_final / m = 0.275 kg*m/s / 0.250 kg = 1.1 m/s

Therefore, the magnitude of the velocity, or final speed of the car in the collision, is 1.1 m/s.

This energy can be calculated using the value of the charges along with the distance between them with the formula Energy = \(k\frac{q1q2}{r}\) in which q represents the charges whilst r represents the distance of separation. As we can see these values are inversely proportional to one another.
