In a physics lab, two identical vinyl wires are secured at both ends and stretched so that the first wire vibrates in the fifth harmonic while the second wire vibrates in the third harmonic. Given that the length of the first wire is 1.20 metres, calculate the required length of the second wire so that both strings can resonate in their respective harmonics under the same conditions of tension and linear density.a.
1.20 metres
b.
0.90 metres
c.
0.80 metres
d.
0.60 metres
e.
The length of the second string should be 0.72 metres.

In an industrial facility, a piping system is employed to transport water for cooling machinery. The primary pipe has an inner diameter of 0.5 meters, and the water moves at a steady speed of 4.0 m/s. At a certain junction, the main pipe divides into two branches: the first has a diameter of 0.3 meters, while the second has a diameter of 0.2 meters. Taking into account the continuity of the flow and assuming there are no losses in volume, calculate the water velocities in each branch after the split of the main pipe.

A solid object is fully submerged in a liquid with a density of 1200 kg/m³ at a depth of 8 metres. Given that the acceleration due to gravity is 9.81 m/s², let’s figure out how the pressure from the liquid on the object changes with depth and how this affects the total buoyant force acting on the object.
