Answer:

The correct answer is option d

Explanation:

because blood pressure decreases as blood moves away from the heart, which is why the heart needs to generate enough pressure so that blood can return to the heart. The pressure drops due to friction between the vessel's walls and the moving blood which exerts a force opposite to the flow of blood, thereby slowing it down. Option a is incorrect because some blood vessels like elastic arteries are not passive and can actually exert a force on the moving blood to help maintain pressure, nevertheless, the blood pressure does decrease due to frictional forces exerted by the vessel walls. Options b and c are incorrect because blood pressure decreases once it leaves the heart.

Answer:

P-waves and S-waves are types of seismic waves that are generated during an earthquake. Seismic waves are waves of energy that travel through the Earth's interior and can be detected by seismometers.

P-waves, also known as primary waves or pressure waves, are compressional waves that move through the Earth by alternately squeezing and stretching the material through which they pass. They can travel through solid, liquid, and gaseous materials, and are the fastest type of seismic wave. P-waves are often the first waves to be detected during an earthquake, and are used to locate the epicenter of the earthquake.

S-waves, also known as secondary waves or shear waves, are transverse waves that move through the Earth by causing the material through which they pass to vibrate at right angles to the direction of the wave. S-waves can only travel through solid materials, and are slower than P-waves. They are used to determine the depth and intensity of an earthquake, as well as the composition and structure of the Earth's interior.

One way to differentiate between P-waves and S-waves is by the way they move through the Earth. P-waves move in the same direction as the wave, while S-waves move at right angles to the direction of the wave. Another way to differentiate between the two types of waves is by their frequency and wavelength. P-waves have a higher frequency and shorter wavelength than S-waves.

The ball is 3.16 seconds in the air before it hits the ground.

GETTING A Grip According to Einstein's general theory of relativity, matter or energy causes a distortion of space (or more specifically, spacetime) known as gravity. A large item produces a gravitational field by distorting the geometry of the spacetime it is located in.

Galileo is credited with demonstrating that gravity causes objects of varying masses to fall with the same acceleration by dropping weights from the Leaning Tower of Pisa.

Solution:

Upward

v = v o - g t

0 m/s = 15 m/s - 9.81 m/s² · t

15 m/s = 9.81 m/s² · t

t = 15 m/s : 9.81 m/s²

t 1 = 1.53 s

h = v o · t - g t² / 2  + 2 m

h = 22.95 m - (9.81 m/s² · 2.3409 s²) / 2 + 2 m

h = 11.475 m + 2 m = 13.475 m

Downward:

13.475 m = 9.81 · t² / 2

t = √(13.475 · 2 ) / 9.81

t 2 = 1.66 s

t = t 1 + t 2 = 1.53 s + 1.66 s = 3.19 s

Wave a carries more energy than wave b. Wave b has a smaller amplitude than wave a.

Those waves carry an amount of energy that can be measured. The energy in a wave is determined by two variables. One is amplitude, which is the distance from the rest position of a wave to the top or bottom. Large amplitude waves contain more energy. Wave A has greater intensity and transfers more energy. Wave B has greater intensity and transfers more energy. Waves that require matter to transfer energy are mechanical waves. The matter through which a mechanical wave travels is called a medium. A mechanical wave travels as energy is transferred from particle to particle in the medium. There are two kinds of mechanical waves. The greater the amplitude of the wave the greater the wave's energy. ... A wavelength will travel only as long as it has the energy to carry. Gamma rays

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. Electromagnetic waves cause oscillations in electrical and magnetic fields. It is important to remember that all waves transfer energy but they do not transfer matter.

The angle of impact of the projectile with the horizontal ground is 26°.

A projectile is formed when an object is thrown in space and the only force acting on it is gravity. Angle of Impact also known as acute angle is made by the velocity vector and the normal to the target surface.

A very well known study of angle of impact is that of blood splatter analysis.

Initial velocity of the projectile is

As the projectile is thrown horizontally the vertical component of the initial velocity is vxy=0

Horizontal component= vix= 11.5m/s

As gravitational acceleration is acting vertically downward let the vertical component of the velocity after time t=0.570s is,

vfy=0+gt

vfy=0+(0.981*0.570)

vfy= 5.59m/s

Horizontal component of the velocity does not change as there is no horizontal acceleration.

so the horizontal component of the final velocity is

vfx=vix=11.5m/s

if Ф be the angle with the horizontal then,

tan Ф=vfy/vfx

tanФ= 5.59/11.5

tanФ=0.486

Ф=tan∧-10.486

The dimension of acceleration is given by, [tex]m^{0} l^{1} t^{-2}[/tex], where m, l, t stand for mass, length and time respectively.

A dimensional equation is created when a physical quantity is expressed as its dimensional formula. The basic numbers [L] for length, [M] for mass, and [T] for time are used to define dimensional formulas in these three dimensions.

The characteristics of a system are quantified using physical quantities. These physical quantities are given significance by the combination of a generally recognised unit and a numerical value. For instance, while describing a beam's length, we may state that it is 6 [numerical quantity] + meters  [unit].

One crucial method for representing these systems in clear languages is through dimensional formulas. A few benefits come from using dimensional formulas to define derived units. It illustrates the representation of various physical quantities in terms of their fundamental units. It serves as a dimensional accuracy check for a derived quantity formula. It lessens errors that happen while translating between different systems' units (say from SI units to British units).

Derivation

We must obtain the formulas for displacement and velocity, two variables on which acceleration depends, in order to determine the dimensional formula for acceleration.

Dimensional Formula for Displacement

Change in position or movement is displacement, thus it is represneted by length.

[d] = [l]

This is also written as:

[d] = [[tex]m^{0} l^{1} t^{0}[/tex]]

This means that displacement has single dimension in length and no dimension in time and mass.

The dimension for displacement is [l].

Dimensional Formula for Velocity

Since velocity [v] is defined as a displacement with respect to time. This is represented as:

v = Displacement/Time

Since displacement [d] is given as [l] we have:

[v] = [l]/[t]

This can be further defined as:

[v] = [tex]lt^{-1}[/tex]

Finally concluded as:

[v] = [[tex]m^{0} l^{1} t^{-1}[/tex]]

The rate at which velocity changes over time is known as acceleration [a]. This is illustrative of:

[a] = Change in velocity/Change in time

Since we previously calculated velocity as [[tex]lt^{-1}[/tex]], acceleration is given as:

[a] =[tex][lt^{-1}]/[t][/tex]

This can be further condensed as follows:

[a]=[ [tex]lt^{-2}[/tex]]

This can also be stated as:

[a] = [[tex]m^{0} l^{1} t^{-2}[/tex]]

The dimensional formula for acceleration is displayed on the right side of the equation above. This dimensional equation states that acceleration has one length dimension, negative 2 of time dimensions, and no mass dimensions.

Rotational inertia is a property of an object which shows its aboility to rotate about an axis.

The rotational inertia of  a rod is given by I = 1/12ML² where

Given that

So, substituting the values of the variables into the equation, we have that

I = 1/12ML²

= 1/12 × 0.030 g × (0.40 cm)²

=  1/12 × 0.030 kg × 0.1600 m²

=  1/12 × 0.0048 kgm²

= 0.0004 kgm²

So, the rotational inertia of the rod is 0.0004 kgm²

The rotational inertia of the weight (as a hoop) is given by I' = 1/2mL' where

Given that

So, substituting the values of the variables into the equation, we have that

According to the solve solution 2.167 m  is the unstretched length of the spring .

Hooke aimed to show how a spring's elasticity and the forces acting on it are related. Hooke's Law asserts that the elongation of a force is proportionate to the load which is supplied to it. As long as the load somehow doesn't above the material's elastic limit, a variety of materials will adhere to this rule.

True, A moving object is constantly speeding up when there is an acceleration in the positive direction.

Our principle states that as an item slows down, the acceleration is going in the opposite direction of the velocity. This object, therefore, has a negative acceleration. The object has a negative velocity and is traveling in the opposite direction as it accelerates.

The rate at which a moving object's speed and direction change over time is known as its acceleration. When anything moves faster or slower, it is said to be moving faster in a straight line. Motion in a circle accelerates even at a constant speed because the direction is continuously changing. The acceleration of all other motions is influenced by both effects.

Due to its magnitude and direction, acceleration is a vector quantity. Speed is another vector quantity. The definition of acceleration is the velocity vector change during a period of time divided by the period of time. The instantaneous acceleration is based on the maximal ratio of the change in velocity (at a specific time and place).

2. The magnitude of the normal force exerted by the shown-covered, horizontal surface is

[tex]F_{g} = F_{N} = 850N[/tex]

3. The magnitude of the force of friction acting on the skis as the skier glides across the snow-covered, horizontal surface is

[tex]F_{f} = 42.5N[/tex]

A force is an external factor that can change the body's state of rest or motion. It has size and direction. The direction in which the force is applied is called the force direction, and the point at which the force is applied is called the force application point.

Frictional force is the force produced by two surfaces touching and sliding against each other. These forces are primarily affected by the surface finish and the amount of force required. The angle and position of the object affect the amount of frictional force.

Answer:

a=5m/s

Explanation:

Forces going to the left:  [tex]F_{3}[/tex]

Forces going to the right: [tex]F_{1}[/tex] and [tex]F_{2}[/tex]

To indicate the different directions, let the forces going to the left be negative, and the sign on forces going to the right be positive.

The total forces acting on the system are:

[tex]F_{1}[/tex] + [tex]F_{2}[/tex] + [tex]F_{3}[/tex]

100N + 80N - 30N = 150N

The overall force is therefore 150N going to the right (sign is positive). Now time to find the overall acceleration:

Force = mass * acceleration

150 = 30a

a=5m/s

The five molecules with speeds of 2.8 m/s, 3.2 m/s, 5.8 m/s, 7.3 m/s, and 7.4 m/s have a root-mean-square speed of 5.7 m/s.

The fact that

The square root of the total squared speeds of all individual gas particle or molecules speeds is known as the root mean square speed.

step 1

determine the square of the velocity of particular particles

2.8²----> 7.84

3.2²——>10.24

5.8²----> 33.64

7.3²----> 53.29

7.4²---> 54.76

average=[7.84+10.24+33.64+53.29+54.76]/5-----> 159.77/5----> 31.954

step 2

determine the square root of the average
