Force is a physical phenomenon that can change an object's shape as well as its state of motion or rest. The SI unit of force is the Newton.

Jib, gantry, and overhead cranes are the three pieces of machinery used most frequently in the industry. Depending on the type of item to be moved, either a chain or wire rope hoist will be used. In the shipbuilding sector, material handling is the main use of overhead cranes during the assembly process.

Laboratory experiments on Earth have examined that each element in the periodic table emits photons only at definite wavelengths (determined by the excitation state of the atoms).

These photons are manifest as either emission or absorption lines in the spectrum of an astronomical object, and by observing the position of these spectral lines, we can detect which components are present in the object itself or along the line of sight.

although, when astronomers observe spectral lines in extragalactic objects (such as galaxies and quasars), they find that the wavelength of the notice spectral lines is different from the laboratory experiments.

In most cases, the wavelength of the spectral lines is longer and thus are shifted toward the red end of the spectrum they are redshifted.

Direction is characterized as the course that anything follows, the route that must be taken to go to a particular location, the direction in which something is beginning to take shape, or the direction you are facing. When you turn right instead of left, that is an illustration of direction.

Reactive power is the power in an AC circuit that is required to establish and maintain a voltage across a load. It is associated with the storage and release of energy in the form of electric and magnetic fields. Reactive power does not contribute to the actual work output of a system and is measured in Volt-amperes reactive (VARs). Power factor is a measure of reactive power relative to the total power in a system.

Source frequency = 60 Hz
Generator impedance = 0 W
Circuit:
Vg = 170 V
R1 = 10 Ω
R2 = 20 Ω
Zb = 20 + j10 Ω

The current flowing through the generator (Ig) and the branch (Ib) can be calculated from Ohm's Law:
Ig = Vg/R1 + Vg/R2 = 170/10 + 170/20 = 17 A
Ib = Ig - Vg/Zb = 17 - 170/(20 + j10) = 17 - 16.4 + j4.4 = 0.6 + j4.4 A
Since Ib is a complex number, we can find its magnitude (|Ib|) and angle (θ):
|Ib| = √(0.6² + 4.4²) = 4.46 A
θ = tan⁻¹(4.4/0.6) = 80.16°
The voltage across the branch (Vb-n) can be calculated using Ohm's Law:
Vb-n = Ib × Zb = (0.6 + j4.4) × (20 + j10) = -8.4 + j74.4 V
The apparent power of the branch (Sb) can be calculated from its voltage and current:
Sb = Vb-n × Ib* = (-8.4 + j74.4) × (0.6 - j4.4) = -45.48 + j367.04 VA
The real power of the branch (Pb) can be calculated from its voltage and current:

A 10 cm radius Styrofoam sphere is submerged in water. So is a 10 cm radius lead sphere. The buoyant force exerted by the water on the Styrofoam sphere is greater than the force exerted on the lead sphere is true.

2.Hot air balloons could be improved by filling them with hydrogen instead of heated air is ta true statement.

Case I- Styrofoam sphere

The buoyant force exerted by a fluid on an object is equal to the weight of the fluid that the object displaces. This means that the buoyant force exerted on the Styrofoam sphere and the lead sphere will be determined by the amount of water that each sphere displaces when it is submerged.

The Styrofoam sphere has a lower density than water, so it will displace a greater volume of water than the lead sphere, which has a higher density than water. This means that the buoyant force exerted on the Styrofoam sphere will be greater than the force exerted on the lead sphere.

To calculate the buoyant force on each sphere, you can use the following formula:

Buoyant force = weight of displaced fluid

The weight of the displaced fluid is equal to the volume of the fluid displaced multiplied by the fluid's density. You can use the formula for the volume of a sphere (V = 4/3πr^³) to calculate the volume of water displaced by each sphere.

For example, if the density of water is 1 g/cm^³ and the radius of each sphere is 10 cm, the volume of water displaced by the Styrofoam sphere would be:

4/3π(10 cm)^³

= 4/3π1000 cm^³

= 4347.19 cm^³

The weight of the displaced water would be:

4347.19 cm^³ * 1 g/cm^³

= 4347.19 g.

The buoyant force on the Styrofoam sphere would therefore be 4347.19 g.

The volume of water displaced by the lead sphere would be the same as the Styrofoam sphere (4347.19 cm^3), but the weight of the displaced water would be greater, due to the higher density of lead.

The weight of the displaced water for the lead sphere would be:

4347.19 cm^³  * 11.34 g/cm^³

= 49359.93 g,

The buoyant force on the lead sphere would be:

49359.93 g.

Therefore, the buoyant force on the Styrofoam sphere would be less than the force on the lead sphere, as stated in the original statement.

Case 2-Hot air balloons

Hydrogen is a lighter-than-air gas, which means that it is less dense than air and has a lower molecular weight. This makes it a potential alternative to heated air as a lifting gas for hot air balloons.

One advantage of using hydrogen as a lifting gas is that it is more buoyant than air, so a hot air balloon filled with hydrogen would be able to lift a greater payload than a balloon filled with air. This could make it possible to design hot air balloons that are larger or carry more passengers or cargo.

However, there are also some significant drawbacks to using hydrogen as a lifting gas for hot air balloons. One concern is the flammability of hydrogen, which is highly explosive and can ignite easily. This makes it potentially dangerous to use in a hot air balloon, as any leaks or accidents could result in a fire or explosion.

Overall, while hydrogen has some potential advantages as a lifting gas for hot air balloons, the risks and costs associated with its use may make it less practical than other options.

= mgdcosФ(-j × i)

= -mgdcosФ(j × i)

= -mgdcosФ(-k)

= (mgdcosФ)k

Given that

Substituting the values of the variables into the equation, we have

τ = (mgdcosФ)k

= (0.05 kg × 9.8 m/s² × 0.75 m × cos60°)k

= (0.05 kg × 9.8 m/s² × 0.75 m × cos60°)k

= (0.3675 kgm²/s² × 0.5)k

= (0.18375 kgm²/s²)k

= (0.18375 Nm)k

≅ (0.1838 Nm)k

So, the torque is (0.1838 Nm)k

The final velocity of the two balls after collision is 1.7 m/s and the direction is 45⁰.

The given parameters;

   mass of the first clay ball, m₁ = 20 g = 0.02 kg

   initial velocity of the first clay ball, u₁ = 3 m/s

   mass of the second clay ball, m₂ = 30 g = 0.03 kg

   initial velocity of the second ball, u₂ = 2 m/s

The initial momentum of the fist ball is calculated as follows;

                               P₁ = m₁u₁

                                  P₁ = (0.02)(3)

                                 P₁ = 0.06 kg.m/s

The initial momentum of the second ball is calculated as follows

                                      P₂ = m₂u₂

                                        P₂ = (0.03)(2)

                                         P₂ = 0.06 kg.m/s

The resultant initial momentum of the two balls is calculated as follows;

Apply the principle of conservation of momentum, to determine the final velocity of the two balls;

A inaccessible object is a dynamic variable on the free store without any pointer pointing to it.

Utilize the sextant's arc to determine the angle. By dividing the object's distance from the point of observation by the tan of the angle you calculated, you may use a scientific calculator to get the object's height.

The measuring of heights and distances that are unreachable is made easier by right-triangle trigonometry. By drawing a right triangle with the unknown height or distance as one of its sides and a known side and angle on the other, it is possible to determine the unknown height or distance.
