An example of the law of conservation of energy is a roller coaster.

The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This means that the total amount of energy in a closed system remains constant over time.

A roller coaster car gains kinetic energy as it moves down the track, but it also loses potential energy. At the bottom of the track, the car has the most kinetic energy and the least potential energy, while at the top of the track, it has the most potential energy and the least kinetic energy. However, the total amount of energy in the system remains constant.

The net charge on the inner surface of the conductor is 7Q, while the net charge on the outer surface of the conductor is -5Q.

In electrostatic equilibrium, charges distribute themselves on the surface of a conductor in such a way that the electric field inside the conductor is zero. Based on this principle, we can analyze the situation step by step:

1. Initially, when the point charge of 7Q is placed inside the cavity of the conductor, the charge redistributes itself on the inner and outer surfaces of the conductor. In order to achieve electrostatic equilibrium, the charges on the inner and outer surfaces of the conductor must be such that the electric field inside the conductor is zero.

2. Since the conductor is electrically neutral, the net charge on the outer surface of the conductor will be equal in magnitude but opposite in sign to the charge inside the cavity. Therefore, the net charge on the outer surface is -7Q.

3. When an additional charge of -5Q is placed on the surface of the inner cavity, the charge redistributes again to achieve electrostatic equilibrium. The charge on the inner surface of the conductor will now be equal in magnitude but opposite in sign to the additional charge placed on the inner cavity. Hence, the net charge on the inner surface is -(-5Q), which simplifies to +5Q.

The net charge on the inner surface of the conductor is 5Q, while the net charge on the outer surface of the conductor is -7Q.

Aerodynamics is a way to reduce drag that uses car manufacturers.

Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.

Aerodynamics is the study of forces that are resulted by motion of the air.

To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.

cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

The values of all sub-parts have been obtained.

(1).  The maximum factored load the beam can withstand is 45.2 kN/m.

(2).  The moment resistance of the cross-section is 291735.65 Nm.

(3).  The factored moment demand is 27939.6 Nm

1) To draw the governing shear and bending moment diagram for the factored load, we need to first calculate the maximum factored load that the beam can withstand.

The maximum factored load on the beam is given by:

Dead Load = 20 kN/m + 15 kN

                   = 35 kN/m.

Live Load = 2 kN/m + 1 kN

                = 3 kN/m.

Total Factored Load = 1.2 x Dead Load + 1.6 x Live Load

                                  = 1.2 x 35 kN/m + 1.6 x 3 kN/m

                                  = 45.2 kN/m.

The maximum factored load the beam can withstand is 45.2 kN/m.

The shear force and bending moment diagrams for the given factored load can be obtained as shown below:

Shear Force Diagram:

Bending Moment Diagram:

2) To calculate the moment resistance of the cross-section, we can use the formula:

MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)

Where, σst = yield stress of tension steel [σst = fy / γst],

γst = safety factor for tension steel [γst = 1.15A']

A' = area of tension steel, [A'' = b(d - a)].

Where,

b = width of the beam [b = 600 mm],  

d = total height of the beam [d= 1000 mm],

a = effective depth of tension steel [a = 920 mm]

f'c = compressive strength of concrete [f'c = 25 MPa],

MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)

MR = (400 / 1.15) x 10 x (1000 - 920/2) + 0.85 x 25 x 590 x (1000 - 920/2)

MR = 291735.65 Nm

The moment resistance of the cross-section is 291735.65 Nm.

3) To check if this cross-section is adequately designed to resist the factored bending moment (LRFD), we need to calculate the factored moment demand and compare it with the moment resistance.

The factored moment demand is given by:

MF = ϕ x Mu

Where,ϕ = resistance factor = 0.9, Mu = factored bending moment

Mu = 1.2 x Dead Load x L2 / 8 + 1.6 x Live Load x L2 / 8 + 1.2 x (Dead Load + Live Load) x L2 / 2

   = 1.2 x 35 x 152 / 8 + 1.6 x 3 x 152 / 8 + 1.2 x 38 x 152 / 2

   = 31044 Nm

MF = ϕ x Mu

     = 0.9 x 31044

    = 27939.6 Nm

The factored moment demand is 27939.6 Nm, which is less than the moment resistance of the cross-section, i.e., 291735.65 Nm.

Therefore, this cross-section is adequately designed to resist the factored bending moment.

The energy required to escape an orbit is dependent on the mass of the object and the velocity at which it orbits.

Therefore, the mass that would require the most energy to escape from its orbit is the one with the greatest mass and the fastest velocity.

In this case, we know that there are five masses orbiting a central mass. Assuming that they are all at the same distance from the central mass, the mass that would require the most energy to escape its orbit would be the one with the greatest mass.

This is because the gravitational force between two masses is proportional to the product of their masses. The greater the mass of an object, the greater the gravitational force it exerts on other objects.

Therefore, the object with the greatest mass would require the most energy to overcome its gravitational pull and escape its orbit.

The direction of acceleration in uniform circular motion is towards the center of the circle. The acceleration is always perpendicular to the velocity and is constantly changing the direction of motion.

The acceleration in uniform circular motion is constant in magnitude but changes its direction with the change in direction of velocity. It acts towards the center of the circle. The net force responsible for this acceleration is known as the centripetal force. The direction of centripetal force is always towards the center of the circle.

In uniform circular motion, the velocity vector of an object moving along a circular path changes continuously. However, the magnitude of velocity remains constant, i.e., it moves with constant speed. The direction of velocity changes because the direction of the object's motion changes. The acceleration in uniform circular motion is given by the equation:

a = v² / r

Where, v is the velocity of the object and r is the radius of the circular path. This equation implies that the magnitude of acceleration increases as the speed of the object increases or the radius of the circular path decreases. But the direction of acceleration is always towards the center of the circle.

The conclusion is that acceleration in uniform circular motion is towards the center of the circle. It is constant in magnitude but changes its direction with the change in direction of velocity. The net force responsible for this acceleration is known as the centripetal force. The direction of centripetal force is always towards the center of the circle.

MA  = 4

VR = 3

e = 0.75 or 75%

work = 12000 [J]

Explanation:

The mechanical advantage in an inclined plane is defined as the relationship between the length of the inclined plane and the height of the plane with respect to the ground.

MA = L/h

MA = 12/3 = 4

Now the real advantage can be calculated as the relationship between the weight of the body and the force being applied.

VR = W/F

VR = 3000/1000

VR = 3

Efficiency can be calculated as the relationship between the real mechanical advantage over the ideal mechanical advantage.

e = VR/MA

e = 3/4

e = 0.75 or 75%

The work is defined as the product of the force by the distance, therefore we have:

work = F*d

work = 1000*12

work = 12000 [J]

If the lead can be extracted with 92.5 efficiency, the mass of ore is required to make a lead sphere with a 7.00 cm radius is 17.707 kg.

To find the mass of ore, the given values are,

The radius of the lead sphere is r = 7.0 cm,

The lead can be extracted with, η = 92.5% = 0.925 efficiency.

Density is the substance's mass per unit of volume.

We know the density of lead as,

⇒ p = 11.4 g/cm³ .

The volume of the lead sphere is,

V = 4/3πr³

   = 4/3π(7)³

V = 1436.7 cm³.

Mass of the lead present in the lead sphere is,

m = p . V

    = 11.4  × 1436.7

    = 16379 g

m = 16.379 kg

From the expression of efficiency, we calculate the mass of the ore,

η = Mass of lead obtained / Mass of the ore to be taken

0.925 = 16.379 kg / Mass of the ore to be taken

Mass of the ore to be taken = 17.707 kg
