Answer:

4.92°

Explanation:

The banking angle θ = tan⁻¹(v²/rg) where v = designated speed of ramp = 30 mph = 30 × 1609 m/3600 s = 13.41 m/s, r = radius of curve = 700 ft = 700 × 0.3048 m = 213.36 m and g = acceleration due to gravity = 9.8 m/s²

Substituting the variables into the equation, we have

θ = tan⁻¹(v²/rg)

= tan⁻¹((13.41 m/s)²/[213.36 m × 9.8 m/s²])

= tan⁻¹((179.8281 m²/s)²/[2090.928 m²/s²])

= tan⁻¹(0.086)

= 4.92°

Pertaining to simple machines and levers what changes when the fulcrum position is modified
ladessa [460]

Explanation :

Simple machines makes our work easier. Lever is one of the simple machine which consists of rigid rod that is pivoted at a fixed support called as Fulcrum.

There are three classes of lever.

Class 1 : In this type of class, fulcrum is placed in between effort and load. Hence the movement of load is in reverse direction of the movement of effort. (fig 1)

Class 2 : In this type of, the load is between the effort and the fulcrum. Hence, the movement of load is in same direction as that of the effort. (fig 2)

Class 3 : In this type of lever the effort between the load and the fulcrum. Hence, both the effort and load are in same direction. (fig 3)

Hence, when the position of fulcrum is modified the effort force changes.

For resistors in series, the equivalent resistance is _____ of their values.
Stels [109]

Answer: The correct answer is "the same as the sum".

Explanation:

The expression for the equivalent resistance in the series combination of the circuit is as follows;

R'=R_{1} +R_{2} +R_{3}

Here, R' is the equivalent resistance, R_{1},R_{2},R_{3} are the resistances.

The expression for the equivalent resistance in the parallel combination of the circuit is as follows;

\frac{1}{R'} =\frac{1}{R_{1}} +\frac{1}{R_{2}}+\frac{1}{R_{3}}

Here, R' is the equivalent resistance, R_{1},R_{2},R_{3} are the resistances.

In the series combination of the circuit, the equivalent resistance is more than the equivalent resistance in the parallel combination of the circuit.

In the series combination of the circuit, the same amount of current flows across the resistance but the voltage is different across the resistances.

Therefore, for resistor in series, the equivalent resistance is the same as the sum.
