Saturn orbits the Sun at a radius of about 1.4×109 km. At this distance the force of gravity on Saturn due to the Sun is 3.7×102

Afina-wow [57]

Explanation:Saturn is the second largest planet of the solar system in mass and size and the sixth nearest planet in distance to the Sun.

In the night sky Saturn is easily visible to the unaided eye as a non twinkling point of light.

2.65 In a standard tensile test a steel rod of 22-mm diameter is subjected to a tension force of 75 kN. Knowing that n 5 0.30 an

Schach [20]

To solve this problem it is necessary to apply the concepts related to uniaxial deflection for which the training variable is applied, determined as

$\delta = \frac{Pl}{AE}$

Where,

P = Tensile Force

L= Length

A = Cross sectional Area

E = Young's modulus

PART A) The elongation of the bar in a length of 200 mm caliber, could be determined through the previous equation, then

$\delta = \frac{Pl}{AE}$

$\delta = \frac{(75*10^3)(200)}{(\pi/4*22^2)(200*10^3)}$

$\delta = 0.1973mm$

Therefore the elongaton of the rod in a 200mm gage length is $0.1973mm$

PART B) To know the change in the diameter, we apply the similar ratio of the change in length for which,

$\upsilon = \frac{l_{a}}{l_{s}}$

Where,

$\upsilon =$ Poission's ratio

$l_{a}$ = Lateral strain

$l_{s}$ = Linear strain

$\upsilon = \frac{\delta/d}{\delta/l}$

$0.3 = \frac{\delta/22}{0.1973/200}$

$0.3(\frac{0.1973}{200}) = \frac{\delta}{22}$

$\delta = 6.5109*10^{-3}mm$

Therefore the change in diameter of the rod is $6.5109*10^{-3}mm$

ankoles [38]

Drag;

Drag is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).

The drag on an object depends on several variables. The most important of them, to understand the experiments you carried out is the area of the object.

The area of the object is the most important factor to understand the experiments.

Mashutka [201]

He does not have much endurance since he is new to exercise. This explains best why Guillermo is struggling.

<h3>What is Endurance?</h3>

An organism's capacity to exert itself and remain active for a prolonged period of time, as well as its capacity to resist, withstand, recover from, and have immunity to trauma, wounds, or exhaustion, are all examples of endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness). Usually, it is employed in anaerobic or aerobic exercise.
Depending on the type of activity, "long" can mean anything from minutes for high-intensity anaerobic exercise to hours or days for low-intensity aerobic exercise.
Unless a person additionally engages in resistance training to offset this effect, training for endurance can impair the ability to exert endurance strength.
