The interference is not destructive, the interference is constructive.

Interference can be constructive or destructive. When two waves pass through the same space at the same time, it is known as interference. If the amplitude of the sum of the waves is less than the amplitudes of the individual waves, then interference is destructive.

Hence, we have to determine whether the interference is destructive when signals modeled by y=20sin (3t+45∘) and y=20sin(3t+225∘) are combined.

In this case, the amplitude of both signals is the same. Hence, we can ignore the amplitude term and consider only the angle component.  

The two signals can be rewritten in terms of the angle component as follows:

y1=3t+45°y2=3t+225°

To find the resultant of the two signals, we add the two signals:

yR=y1+y2=y1=3t+45°+y2=3t+225°=6t+270°

We know that the sine function repeats itself every 360 degrees. Hence, we can rewrite the above equation as:

yR=6t+270°=6t+360°−90°=6t−90°

From the above equation, the resultant signal can be written as: yR=20sin(6t−90°)To determine whether the interference is destructive or not, we check if the amplitude of the resultant wave is less than the individual waves.

Since the amplitude of each signal is 20, the amplitude of the resultant wave is also 20. Hence, the interference is constructive. This is because the two signals are exactly out of phase, and they interfere to create a stronger signal. Therefore, the interference is not destructive.

note: gravitational field strength (g) = 10 N/Kg

55 x 15 x 10 = 8250

gpe = 8250j

Explanation:

a) The average annual evaporation from the catchment is approximately 180.29 mm/year.

b) The exact value of evapotranspiration from the irrigated area cannot be calculated due to missing information.

a) Average annual evaporation from the catchment in mm/year:

First, we calculate the total annual rainfall that is collected by the catchment area:

800,000,000 m² × 0.2 m = 160,000,000 m³/year

Since this is the only source of water for the catchment, the total amount of water available to the catchment area per year will be 160,000,000 m³/year.

We know that the average annual discharge at the outlet of a catchment is 0.5 m³/s, and since there are 31,536,000 seconds in a year, we can calculate the total volume of water that is discharged per year:

0.5 m³/s × 31,536,000 s = 15,768,000 m³/year

So, the total volume of water that is lost through evaporation per year will be:

160,000,000 m³/year - 15,768,000 m³/year = 144,232,000 m³/year

To convert this into millimeters, we need to divide this value by the area of the catchment in square meters, and then multiply by 1000 (since 1 m = 1000 mm):

144,232,000 m³/year ÷ 800,000,000 m² × 1000 mm/m = 180.29 mm/year

Therefore, the average annual evaporation from the catchment is approximately 180.29 mm/year.

b) Evapotranspiration from the irrigated area in mm/year:

Since we know that the size of the irrigated area is 10 km² = 10,000,000 m², we can calculate the total volume of water that is used for irrigation each year by multiplying this area by the amount of discharge that is lost as a result of the irrigation project:

10,000,000 m² × (0.5 m³/s - 0.175 m³/s) × 31,536,000 s/year = 4,422,480,000 m³/year

To calculate the amount of water that is lost through evapotranspiration from the irrigated area, we need to know the crop coefficient and the reference evapotranspiration (ET0) for the area. However, since this information is not provided in the question, we cannot calculate the exact value of evapotranspiration from the irrigated area.

Changing the vehicle balance or changing the weight from front to back is called weight transfer.

The vehicle's balance refers to the distribution of weight on the car's wheels. It's about finding the right amount of weight for each wheel so that the car can travel smoothly and safely. The balance is determined by the vehicle's weight, suspension, and wheel alignment.When a vehicle accelerates, decelerates, or turns, weight transfer occurs. Weight is transferred to the front wheels when a vehicle brakes, and it is transferred to the rear wheels when it accelerates. During a turn, the vehicle's weight is shifted from one side to the other. This shift of weight, or weight transfer, causes the vehicle's balance to shift.Weight transfer is critical since it affects a vehicle's handling and performance. Weight transfer can cause a car to understeer or oversteer if it is not properly managed. It can also cause the vehicle's wheels to lose traction if weight is shifted too far in one direction. As a result, weight transfer is a critical component of vehicle design and driving technique.

A box sliding on a frictionless surface collides and sticks to a second identical box which is initially at rest. Compare the initial kinetic energy Kinitial and final kinetic energy Kfinal of the system, we have  Kinitial = Kfinal.

The initial kinetic energy (Kinitial) of a box sliding on a frictionless surface is the sum of the kinetic energy of the box and the velocity of the box before the collision. The final kinetic energy (Kfinal) of the system is the sum of the kinetic energy of the two boxes after the collision, and any additional energy that is created during the collision. When the two boxes collide and stick together, the kinetic energy of the system is conserved.

This means that the total kinetic energy of the system remains the same, and thus Kinitial = Kfinal. Since Kinitial = Kfinal, the velocity of the two boxes must also be the same after the collision. This is due to the conservation of momentum, which states that the total momentum of a system must remain the same before and after a collision. Therefore, the final velocity of the two boxes after the collision must be the same as the initial velocity of the box that was sliding on the frictionless surface.

In other words, the total energy of the system remains the same, but the energy is distributed differently among the two boxes. The situation changes when the two boxes have different masses. In this case, the momentum of the system is conserved, but the total energy of the system is not. This is because the kinetic energy of the system is determined by the total mass of the system and the square of its velocity.

Since the masses of the two boxes are different, the kinetic energy of the system is not the same before and after the collision. Therefore,  K initial = K final.

Explanation:

Sum of the forces in the first 6.00 s:

∑F = ma

F − mg = ma

35.0 N − (0.800 kg) (10 m/s²) = (0.800 kg) a

a = 33.75 m/s²

The height it reaches during this time is:

Δy = v₀ t + ½ at²

Δy = (0 m/s) (6.00 s) + ½ (33.75 m/s²) (6.00 s)²

Δy = 607.5 m

The velocity it reaches is:

v = at + v₀

v = (33.75 m/s²) (6.00 s) + 0 m/s

v = 202.5 m/s

After the battery runs out, the drone is in free fall.  At the highest point, the velocity is 0.  The height at this point is:

v² = v₀² + 2aΔy

(0 m/s)² = (202.5 m/s)² + 2 (-10 m/s²) (h − 607.5)

Particle 1 and Particle 2, two particles are observed to have the same centripetal force. Correct options are (A) and (B).

A centripetal force is any force that shifts the direction of motion in the direction of the centre of a circular motion. The portion of the force that is perpendicular to the velocity creates the centripetal force.  

The formula for centripetal acceleration is a = v²/r.

For particle 1: a₁ = v²/r

For particle 2; a₂ = (2v)²/2r = 2v²/r

For particle 3; a₃ = (v/2)²/r = v²/4r

For particle 4; a₄ = (2v)²/3r = 4v²/3r

Centripetal force (F) = ma

Distance apart (r) = 0.05 m

Electric field constant (K) = 9×10⁹ N•m²/C²

Electron (e) = 1.6×10¯¹⁹ C.

Electric Force (F) =..?

Next, we shall determine the value of the two charges.

This is illustrated below:

Charge 1 (q1) = - 4e

Charge 1 (- q1) = 4e

Electron (e) = 1.6×10¯¹⁹ C.

Charge 1 (- q1) = 4 × 1.6×10¯¹⁹ C.

Charge 1 (- q1) = 6.4×10¯¹⁹ C.

Charge 2 (q2) = + 3e

Electron (e) = 1.6×10¯¹⁹ C.

Charge 2 (q2) = 3 × 1.6×10¯¹⁹ C.

Charge 2 (q2) = 4.8×10¯¹⁹ C.

Finally, we shall determine the value of the electric force. This can be obtained as shown below:

Charge 1 (- q1) = 6.4×10¯¹⁹ C.

Charge 2 (q2) = 4.8×10¯¹⁹ C.

Electric field constant (K) = 9×10⁹ N•m²/C².

Distance apart (r) = 0.05 m

Electric Force (F) =..?

F = Kq1q2 /r²

F = (9×10⁹× 6.4×10¯¹⁹× 4.8×10¯¹⁹)/(0.05)²

Work is the energy transferred to or from an object when a force is applied over a distance. In other words, work is done when a force moves an object.

To calculate the work done by air resistance on the feather, we need to know the change in kinetic energy of the feather due to air resistance. The initial kinetic energy of the feather at the top is zero, and the final kinetic energy of the feather just before it hits the ground is given by:

Kf = (1/2) * m * v^2

where m is the mass of the feather, v is the final velocity of the feather just before it hits the ground.

Kf = (1/2) * 0.002 kg * (0.20 m/s)^2 = 0.00002 J

The work done by air resistance is equal to the change in kinetic energy of the feather:

W = Kf - Ki

where Ki is the initial kinetic energy of the feather at the top, which is zero.

W = Kf - Ki = 0.00002 J - 0 J = 0.00002 J

The statement declaring that there can be no perfect heat engines is attributed to the Kelvin-Planck statement.

According to this principle, it is impossible to create a heat engine that operates with 100% efficiency, where all the input heat energy is converted into useful work output without any waste heat. This statement forms one of the cornerstones of thermodynamics and has significant implications for the design and performance of real-world heat engines.

The Kelvin-Planck statement is named after William Thomson, also known as Lord Kelvin, and Rudolf Clausius, who independently formulated the principle. It states that it is impossible for a heat engine to produce a net amount of work by exchanging heat solely with a single heat reservoir. In other words, in any heat engine cycle, there must be at least one heat reservoir at a lower temperature where waste heat is expelled. This principle is a consequence of the second law of thermodynamics, which states that heat naturally flows from hot to cold regions and cannot spontaneously flow in the opposite direction. Therefore, achieving perfect efficiency in a heat engine is unattainable due to the limitations imposed by the Kelvin-Planck statement.

The average power delivered to the circuit is 7.84 W. To calculate the average power delivered to the circuit, we can use the formula:

Pavg = (1/2) * Vrms² / R

Where Pavg is the average power, Vrms is the root mean square voltage, and R is the resistance in the circuit.

First, we need to find the root mean square voltage (Vrms) using the given AC voltage equation:

Vrms = Δv / √2

Δv = 90.0 V (given)

Vrms = 90.0 V / √2 ≈ 63.64 V

Now, substituting the values into the average power formula:

Pavg = (1/2) * (63.64 V)² / 50.0 Ω

Pavg ≈ 7.84 W

Therefore, the average power delivered to the circuit is approximately 7.84 W.

In an AC circuit with a series R L C configuration, the average power delivered can be calculated using the formula Pavg = (1/2) * Vrms² / R. In this scenario, we are given the AC voltage equation Δv = 90.0 sin 350 t, where Δv is in volts and t is in seconds. Additionally, the resistance (R), capacitance (C), and inductance (L) values are provided.

To calculate the average power, we first need to find the root mean square voltage (Vrms) by dividing the given voltage amplitude by √2. This gives us Vrms = 90.0 V / √2 ≈ 63.64 V.

Substituting the values into the average power formula, we have Pavg = (1/2) * (63.64 V)² / 50.0 Ω. Simplifying this equation, we find Pavg ≈ 7.84 W.

The average power delivered to the circuit represents the average rate at which energy is transferred to the components in the circuit. It is important in determining the efficiency and performance of the circuit. In this case, the average power delivered is approximately 7.84 W, indicating the average amount of power dissipated in the circuit due to the combined effects of resistance, inductance, and capacitance.
