Bond [772]

Answer;

-Period

Explanation;

-Properties of elements within a period on the periodic table change in a predictable way from one side of the table to the other. A period in the periodic table is a horizontal row. All elements in a row have the same number of electron shells.

-Elements in the same period have the same number of electron shells; moving across a period, elements gain electrons and protons and become less metallic.This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

STatiana [176]

Answer:

by doing rapid shallow breathing and pursed lip breathing  

Explanation:

Pressure with in the chest wall and the outside of the lungs remains negative because the intrapleural pressure is always lesser than the intra-alveolar pressure or atmospheric pressure. In general forced expiration leads to an increasing positive pressure in pleura. This happens because the pleura airway gets compressed and the size of airway reduces thereby forcing expiration.  

People who are able to resist airway can increase airflow by doing rapid shallow breathing and pursed lip breathing

How did the angular acceleration change with the new moment of inertia? was your prediction correct?
elena55 [62]

In Newtonian physics, the acceleration of a body is inversely proportional to mass. In Newtonian rotational physics, angular acceleration is inversely proportional to the moment of inertia of a frame.

The moment of Inertia is frequently given the image I. it's miles the rotational analog of mass. The moment of inertia of an object is a measure of its resistance to angular acceleration. because of its rotational inertia, you want torque to change the angular pace of an object. If there may be no net torque acting on an object, its angular speed will no longer change.

In linear momentum, the momentum p is the same as the mass m instances of the velocity v; whereas for angular momentum, the angular momentum L is the same as the instant of inertia I times the angular pace ω.

What distance will a vehicle travel before coming to a complete stop from a speed of 70 mph, (a) When the vehicle is traveling o
OLga [1]

Answer:

(a), The SSD will be 723.9 ft.

(b-1), The SSD will be 620.2 ft.

(b-2), The SSD will be 723.91>SSD>620.2

(c), The SSD will be 910.5 ft.

Explanation:

Given that,

Speed = 70 mph

Suppose, a perception reaction time of 2.5 sec and the coefficient of friction is 0.35

We need to calculate the stopping sight distance

Using formula of SSD

SSD=1.47\times v\times t+\dfrac{v^2}{30\times(f\pm g)}

Where, v = speed of vehicle

t = perception reaction time

f = coefficient of friction

g = gradient of road

(a). If the gradient of road is zero.

Then, the stopping sight distance will be

SSD=1.47\times 70\times 2.5+\dfrac{70^2}{30\times(0.35)}

SSD=723.9\ ft

(b-1). If the gradient of road is 0.1

Then, the stopping sight distance will be

SSD=1.47\times 70\times 2.5+\dfrac{70^2}{30\times(0.35+0.1)}

SSD=620.2\ ft

(b-2). If the grade continuously decrease then the SSD will be increase.

But if the grade is increase then the SSD will be decrease and for flat grade the SSD will be more.

So, The SSD will be 723.91>SSD>620.2

(c). When the vehicle is traveling downhill on a roadway of constant grade then the vehicle take will be more SSD

So, The SSD will be

SSD=1.47\times 70\times 2.5+\dfrac{70^2}{30\times(0.35-0.1)}

SSD=910.5\ ft

Hence, (a), The SSD will be 723.9 ft.

(b-1), The SSD will be 620.2 ft.

(b-2), The SSD will be 723.91>SSD>620.2

(c), The SSD will be 910.5 ft.
