A "C" flute creates the note C4 when it is played at its resonance frequency, that is 261 Hz on the evenly tempered scale. Flute frequencies are changed by opening holes in its tube, creating a node at that hole and effectively shortening the 66 cm long tube. The flute and the guitar make a good instrumental combination, and for that they must be tuned together. You have seen that a guitar's 6 strings are usually tuned to (E) 329.63 Hz E4 (B) 246.94 Hz B3 (G) 196.00 Hz G3 (D) 146.83 Hz D3 (A) 110.00 Hz A2 (E) 82.41 Hz E2

1. Is there a way to lower the frequency of the flute so that it matches one of these open strings at resonance? Explain your answer.

2. Given the length of its tube and the frequency of the flute sound, what is the speed of sound in air it has been made for?

3. At what temperature would the air be in °C to give this speed? What is that in °F?

4. At this temperature, what is the most probable speed of a nitrogen molecule in m/s?

Q4. A restaurant in Suwaiq requires 85000 Whr of heat during winter season for the month of January to March to retain a constant inside temperature of 295 K. If the solar heating system has 40 % efficiency, design a storage tank and collector with appropriate size based on the given data. Assume the temperature of the hot water at the outlet of the storage tank is 69 0C. Represent the space heating setup with a neat sketch. Under which category this type of space heating falls? justify your answer. Also, discuss and analyze the effects on the collector area and the mass of water, when the solar radiation changes from every month by considering the suitable global solar radiation data?

John imagines himself on the beach playing some volleyball once Memorial Day comes around. After a victorious game, John always dreams of a cold cup of water but as his future holds he only has 40.0 g of water at room temperature (25°C).

a. How much heat will be released if all the water, 40 g at 25°C, is converted to ice at 0°C.

b. If John still has his original cup of 40.0 g of water at room temperature (25°C), determine the composition and temperature of the mixture if John adds 30.0 g of ice at -10.0°C into the liquid water? Show how you arrived to this conclusion.

Describe how to differentiate from rod shaped particles, disk shaped particles, and a detector background signal in Small Angle X - Ray Scattering (SAXS).

A parallel-plate capacitor with plates of area 590 cm2 and is connected across the terminals of a battery. After some time has passed, the capacitor is disconnected from the battery. When the plates are then moved 0.48 cm farther apart, the charge on each plate remains constant but the potential difference between the plates increases by 100 V.

(a) What is the magnitude of the charge on each plate?

(b) Do you expect the energy stored in the capacitor to increase, decrease, or remain constant as the plates are moved this way? Explain your answer.
(c) Support your answer to Part (b) by determining the change in stored energy in the capacitor due to the movement of the plates.

Write a short account (400 words) on the properties of the three main types of ionising radiation.

(b) (2 points) What is the magnetic field B⃗w at the location of the electron due to the wire. Give your answer in terms of x, y and z components.

(c) (2 points) What is the total magnetic field B⃗ at the location of the electron. Give your answer in terms of x, y and z components.

(d) (2 points) What is the Lorentz force experienced by the electron? Give your answer in terms of x, y and z

Will they have exactly the same fundamental (lowest) frequency? Explain

Youre a student in the General Physics 1 course. Your friend the lawyer, contacts you to consult the case of a client of his who has been injured in a traffic accident. The car of the client was rear-ended by another vehicle while stopped. The judge who is taking the case, argues that, if the vehicle of the affected had been in movement, the injuries would not have been as severe. Is the judge correct? Or do you think can I win this case? Investigate and make an argument based on the concepts studied in physics class (especially energy and momentum) and support your arguments with a development of mathematical equations that demonstrate their answer

Calculate the terminal velocity in free fall of a bowling ball (mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of 0.51 kg, diameter of 23.85 cm). The bowling ball can be considered a smooth sphere (Cd = 0.1), while the basketball can be considered a rough sphere (Cd = 0.4). What would be the terminal velocity of the basketball if we considered it a smooth sphere?
