What are the major components of a truss bridge?
Answer:
In a truss bridge, two long - usually straight members known as chords - form the top and bottom; they are connected by a web of vertical posts and diagonals. The bridge is supported at the ends by abutments and sometimes in the middle by piers.

10N/m
Jeremy is pushing his two children on a set of swings. He gives his daughter a push and she swings
Jeremy gives his son the same push, but he only swings about two feet high. What could account f
the kids got?
Jeremy's daughter has more mass, so it takes less force to get her into the air.
Jeremy's son has more mass, so it would take more force to reach the same height as his da
O
Jeremy's son has less mass, so it would take more force to reach the same height as his da
O
Jeremy's daughter has more mass, so she accelerates faster than his son.
Round off the following numbers to three significant digits:
43.659
Answer: 43.7
Explanation: Simply round the number so that there are only three digits in the number.
We have that 43.659 rounded to three significant digits is
[tex]43.659=43.7[/tex]
From the Question we are Given
Integer=43.659
To round off to three significant digits means to represent only three digits
Therefore
43.659 in three digits is

The apparent depth of an object at the bottom of a tank filled with a liquid of refractive index 1.3 is 7.7 cm. What is the actual depth of the liquid in the tank?
[tex]{\bold{\blue{GIVEN}}}[/tex]

The energy stored by any pair of positive charges is inversely proportional to the distance between them, and directly proportional to their charges. Three identical point charges start at the vertices of an equilateral triangle, and this configuration stores 15 Joules of energy. How much more energy, in Joules, would be stored if one of these charges was moved to the midpoint of the opposite side
Answer:
U = 25 J
Explanation:
The energy in a set of charges is given by
U = [tex]k \sum \frac{q_i}{r_i}[/tex]
in this case we have three charges of equal magnitude
q = q₁ = q₂ = q₃
with the configuration of an equilateral triangle all distances are worth
d = a
U = k ( [tex]\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3}[/tex] )
we substitute
15 = k q² (3 / a)
k q² /a = 5
For the second configuration a load is moved to the measured point of the other two
d₁₃ = a
The distance to charge 2 that is at the midpoint of the other two is
d₁₂ = d₂₃ = a / 2
U = k (\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3})
U = k q² ( [tex]\frac{2}{a} + \frac{1}{a} + \frac{2}{a}[/tex] )
U = (kq² /a) 5
substituting
U = 5 5
U = 25 J
Tenemos un Cable de cobre de 1 km de longitud cuya sección es de 2 milímetros al cuadrado y queremos saber la resistencia que señalara el ohmetro , su temperatura es de 20°
Answer:
8.5 Ω
Explanation:
La resistencia de un material es directamente proporcional a su longitud e inversamente proporcional al área de la sección transversal.
La fórmula de la resistencia (R) viene dada por:
R = ρL/A
Donde ρ es la resistividad del material, L es la longitud del material y A es el área de la sección transversal del material.
Dado que:
L = 1 km = 1000 m, A = 2 mm² = 2 * 10⁻⁶ m², ρ (cobre) = 1.7 * 10⁻⁸ Ωm
Sustituyendo da:
R = 1,7 * 10⁻⁸ * 1000/2 * 10⁻⁶
R = 8.5 Ω

Determine la inercia rotacional de una varilla de 4 m de largo y 2 Kg de mesa si su eje de rotación esta situado a la mitad de la varilla.
Answer:
I = 2.667 kg m²
Explanation:
The moment of inertia of a body can be calculated by the expression
I = ∫ L² dm
For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is
I = [tex]\frac{1}{12}[/tex] m L²
let's calculate
I = [tex]\frac{1}{12}[/tex] 2 4²
I = 2.667 kg m²
