Answer:

a. Air fuel Ratio = 19.76 kg air/kg fuel

b. % Theoretical air used = 131%

c. Amount of H2O that condenses as the products are cooled to 25°C at 100kPa = 6.59 kmol

The Acceleration of the system is 6.41 m/s².

Given,

α= 15°, m₁ = 7kg

β= 65°, m₂ = 11 kg

Let, a be the acceleration and T is the tensions at the end it's the cord.

Let, the mass m₂ be coming down along the inclined plane along the inclined surface towards downward m₂g sin β and the tension in the upward direction,

Resultant force, m₂a=m₂g sin β -T

11a=((11) ×g sin 65°) -T  ...(i)

Now, considering the motion of m₁ which moves downwards, the forces are m₁g sinα, and T both are acting downwards.

Resultant force m₁a = m₁g sin α+T

7a =7g sin 15°+T  ...(ii)

Solving both the equations by adding them,

18a=11gsin 65°+7g sin 15°-T+T

18a=11gsin 65°+7g sin 15°=115.45

a=115.45/18=6.41 m/s²

Hence, the Acceleration of the system is 6.41 m/s².

A student moves a horseshoe magnet by hand across a tabletop to varying distances from an electromagnet, as shown in the diagram
Sloan [31]

The closer together they are the harder it is to hold on to because the magnetic field is stronger as it gets closer.


Answer:

D. The electromagnet's magnetic field is stronger close to it than far from it.​

A merry-go-round can be modeled as a solid disk of radius R and mass M. Initially, it is rotating on a sturdy frictionless axle
Crazy boy [7]

Answer:

w = w₀ M / (M + 2m)

Explanation:

This exercise can be solved using the concepts of conservation of angular momentum

          L = I w

Let's write in angular momentum in two points

Initial. Before impact

        L₀ = I w₀

Final. After the rock has stuck

        L_{f} = I w + (m r²) w

The system is formed by the disk and the rock, so that the forces and moments during the crash are internal and the angular momentum is preserved

        L₀ =  L_{f}

        I w₀ = (I + m r²) w

       w = w₀ I / (I + m r²)

The roundabout is a disk so its moment of inertia is

         I = ½ M r²

        w = w₀ ½ Mr² / (½ M r² + mr²)

        w = w₀ ½ M / (½ M + m)

        w = w₀ ½ M2 / (M + 2m)

        w = w₀ M / (M + 2m)
