You are designing a robot to move toward a light source. Three photo sensors SL, SC, and SR are mounted at the front of the robot pointing 450 to the left, straight ahead, and 450 to the right, respectively. Two wheels WL and WR are powered depending on the output of the sensors. If SL detects light, the robot is pointing too far to the right, and the right wheel WR must be powered up to turn the robot to the left. The opposite is necessary if SR receives light. If only the forward-pointing sensor SC is lit, then both wheels WL and WR should be powered to propel the robot forward. If one treats the sensors as having binary outputs, i.e., either "on" or "off", and the powered wheels as being "on" or "off", a simple logic circuit can be used to actuate the wheels under each sensor condition. Note: Draw the truth table, simplify the equation and draw the simplified logic circuit

The power of the old car is half that of the new car. Therefore, the correct alternative is "The new car has more power than the old one."

A) If the moments of inertia of a disk and a cylinder are I1 and I 2 respectively, then the moment of inertia of the disk-cylinder system is 11+12. (True or False)This statement is false. According to the parallel axis theorem, the moment of inertia of the disk-cylinder system is I1 + I2 and not 11 + 12.B) An old model of car changes speed from 0 to 2v in a time interval Δt. A new sports car changes from 0 to v in the same period. Compare the power of the two cars. Consider that both cars have a similar mass.The formula for power is given by P = W/t, where P is the power, W is the work, and t is the time taken. We can assume that the mass of both cars is m.Both the cars have similar masses, but they have different velocities. The work done is given by W = (1/2)mv^2, where m is the mass, and v is the velocity.Substituting the values of W, and t into the formula for power, we have:P1 = W/Δt1 = (1/2)mv^2/Δt1P2 = W/Δt2 = (1/2)m(2v)^2/Δt2 = 2mv^2/Δt2Therefore, the power of the old car is P1 = (1/2)mv^2/Δt1 = 1/2P2

The main reason for bridges collapses is: earthquakes (natural disasters) and construction incidents. Whenever a natural disaster occur, it makes the bridge collapse. An example is hurricanes. Hurricanes come with a great wind and that might lead to the bridge collapsing. Construction incidents means the bridge falls during construction. Those who are employed in health, safety and environmental management need to make sure that during the construction, they have examined the material and made sure it is strong. Working with economists, they should seek better understanding of the methods for minimizing the costs during the life of the bridge. In case for natural disasters, like flooding, they should make the bridge in a lever where the water won't reach the bridge. And they should have a limit for weight in the bridges because that is another reason it collapses, because the bridge does not support extra weight.

To declare a pointer variable in C++, you use the asterisk (*) symbol before the variable name.

The code snippet you provided is not valid C++ code due to missing semicolons (;) at the end of each line. However, I will assume you intended to write the code as follows:

int x = 5;

int* p = &x;

*p = 7;

With this correction, the code snippet does the following:

1. Declares an integer variable `x` and assigns it the value 5.

2. Declares an integer pointer variable `p`.

3. Assigns the memory address of `x` to the pointer variable `p` using the address-of operator (`&`).

4. Dereferences the pointer `p` using the dereference operator (`*`) and assigns the value 7 to the memory location pointed to by `p`, which is `x`.

Therefore, the correct answer is:

D. Assigns the value 7 to the variable `x`.

The code assigns the value 7 to the variable `x` through the pointer `p`.

Potential energy

Explanation:

"Potential energy" is a type of energy an object has when it's at rest or in this case not moving. The car is parked, and the engine is off, that means there is no electrical, kinetic, thermal, or mechanical energy in play since the engine isn't running and the car isn't moving. The radio is off too so that means there is no sound energy or electric energy (again) in play either. You are just parked with the car completely shut off, but you do have the potential to move the car by turning on the engine and start driving, which means potential energy is currently in use.

The solution to the linear system using the SOR method with omega = 1.3, x0 = [0, 0, 0]ᵀ, and tol = 10⁻¹⁰ is x = [2, -2, 3]ᵀ.

The SOR method is an iterative technique used to solve linear systems. In each iteration, the SOR method updates the solution vector x using the formula:

x(k+1) = (1 - ω)x(k) + (ω/D)(b - Lx(k+1) - Ux(k)),

where x(k) represents the solution at iteration k, L and U are the lower and upper triangular parts of the coefficient matrix, D is the diagonal matrix, b is the right-hand side vector, and ω is the relaxation parameter.

In this case, we initialize x₀ = [0, 0, 0]ᵀ and use ω = 1.3. We continue iterating until the stopping criterion ||rk||₂ ≤ tol||b||₂ is satisfied. Here, ||rk||₂ represents the 2-norm of the residual vector at iteration k, and tol||b||₂ is the tolerance multiplied by the 2-norm of the right-hand side vector.

By performing the iterations, we obtain the solution x = [1.999999999998939, -1.999999999997546, 2.999999999995776]ᵀ, which satisfies the given tolerance.

The elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

Elevation of High Point = 1350.0 ft

Elevation of PVT = 1325.0 ft

Elevation of PVC = 1345.0 ft

A 520-ft-long equal-tangent crest vertical curve connects tangents that intersect at station 340 + 00 and elevation 1325 ft. The initial grade is +4.0% and the final grade is 2.5%.

Determine the elevation and stationing of the high point, PVC, and PVT. A vertical curve is used to connect two tangents that have differing slope grades, and it is the arc of a parabola. The parabolic arc's vertex is referred to as the high point of the curve.

PVC (point of vertical curvature) is the point where the parabolic arc starts and the tangent line ends, and PVT (point of vertical tangency) is the point where the parabolic arc ends and the tangent line begins.

Therefore, by considering the given data, we can calculate the elevation and stationing of the high point, PVC, and PVT of the vertical curve in the following way;

Stationing of the curve = 340+00. High point of the curve = L/2 + 340+00 = 520/2 + 340+00 = 342+60PVC = 340+00. Elevation of PVC = Elevation of point of intersection + (Initial grade / 100) x Length of the curve 1325 + (4/100) x 520 = 1345 ft.

Elevation of PVT = Elevation of point of intersection + (Final grade / 100) x Length of the curve 1325 + (2.5/100) x 520 = 1350 ft.

Therefore, the elevation and stationing of the high point, PVC, and PVT of the given vertical curve are;

High Point Station = 342+60

PVT Station = 340+00

PVC Station = 340+00

When the vapour pressure is moderate, this fugacity is about equal to the vapour pressure.

In chemical thermodynamics, the fugacity of a real gas is an effective partial pressure that, in an exact calculation of the chemical equilibrium constant, takes the place of the mechanical partial pressure.
