My answer:

One of the real world examples mentioned in the article was that of a rocket blasting off into space. It was explained that it's an example of Newton's third law because the rocket’s engines push on those gases (action force), and the gases push back (reaction force). This reaction shows an excellent example of Newton's third law.

A 1.3 kg mass starts from rest and slides down an inclined plane 8.7 ✕ 10-1 m long in 0.37 s. What net force is acting on the mass along the incline?

Answers

Answer:

The net force acting on the mass is 16.523 N

Explanation:

The given mass of the object, m = 1.3 kg

The length of the inclined plane over which the mass slides = 8.7 × 10⁻¹ m

The time it takes the mass to slide = 0.37 s

Therefore, we apply the following kinematic equation of motion;

s = u·t + 1/2·a·t²

Where;

u = The initial velocity of the mass = 0 m/s

t = The time taken for the motion = 0.37 s

a = The acceleration

s = The distance moved in the motion = 8.7 × 10⁻¹ m = 0.87 m

Plugging in the values gives;

0.87 = 0 × t + 1/2 × a × 0.37²

∴ 0.87 = 1/2 × a × 0.37²

a = 0.87/(1/2 × 0.37²) ≈ 12.71 m/s²

The net force acting on the mass is F = Mass, m × Acceleration, a force = m × a

Therefore, the net force acting on the mass is F = 1.3 × 12.71 = 16.523

The net force acting on the mass, F = 16.523 N.

The net force acting on the mass along the incline is 16.523 N

From the information given:

the mass of the object = 1.3 kgthe length which corresponds to the distance (S) of the inclined plane = 8.7 × 10⁻¹ m the time taken = 0.37 s

According to the second equation of motion;

[tex]\mathbf{S = ut + \dfrac{1}{2}at^2}[/tex]

the initial velocity u = 0 m/s since the mass starts from the rest

[tex]\mathbf{S =0(t) + \dfrac{1}{2}at^2}[/tex]

[tex]\mathbf{S = \dfrac{1}{2}at^2}[/tex]

2S = at²

[tex]\mathbf{a = \dfrac{2S}{t^2}}[/tex]

[tex]\mathbf{a = \dfrac{2\times 0.87 \ m}{0.37^2}}[/tex]

acceleration (a) = 12.71 m/s²

The net force now acting on the mass along the incline can now be estimated as:

[tex]\mathbf{F_{net} = ma}[/tex]

[tex]\mathbf{F_{net} = 1.3 \ kg \times 12.71 \ m/s^2}[/tex]

[tex]\mathbf{F_{net} = 16.523 \ N}[/tex]

Therefore, we can conclude that the net force acting on the mass along the incline is 16.523 N

Answers

Adding the rise time and fall time then the package to reach the ground in 3.647 second.

Time can be defined in the sence as,that it is a continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.

We are given that ,

The packege 's trajectory into a rise to maximum height and fall from there to the ground .Rise to maximum height begins at vertical position is  given as,

Vertical position of the helicopter = H₀ = 20 m,

Initial velocityof helicopter = u = 14 m/s upward

Covered time of the helicopter =t₁ = 0,

Acceleration under gravity of helicoper=(- a) = -9.81 m/s²

Rise ends when instantaneous velocity v = 0,

Therefore, from the equation of motion for velocity as a function of time is  written as ,

v = a + at

0 = 14 m/s - (9.81 )m/s² t₁

t₁ = 1.427sec

Thus , the velocity changes linearly over time t₁ sec from u = 0 m/s then the averaging velocity can be given by w i.e.

w = u /2 = (14m/s)/2

w = 7 m/s

Therefore, maximum height of packege is given as,

H₁ = H₀ + w × t₁

H₁ =20m + 9.81m/s (1.427)s

H₁ = 33. 998 m

Therefore, when the packege fall from maximum height begins at ,

Time= t₁ = 0,

Position= h = H₁

Velocity= u = 0, and

Acceleration due to gravity downward=(-a) = -9.81 m/s²

Thus the  equation of motion for position (s) as a function of initial position (h) is can be written as,

s = h + ut₁ + (1/2) at₂²

0 = H₁ + 0 + (1/2) (-9.81)t₂²

t₂² = 4. 890 s

t₂ = 2.21 s

Hence , on adding the rise time t₁ and fall time t₂

Total time T = t₁ + t₂

T = 1.427 s + 2.21s = 3.647 s

Two parallel wires are separated by 6.00 cm, each carrying 3.00 A of current in the same direction.(b) Is the force attractive or repulsive?

Answers

The force is attractive.

The force between two parallel currents I₁ and I₂ that are spaced apart by r is measured as the ratio F/L. If the currents are flowing in the same direction, the force is attracting; if not, it is repulsive.

Each parallel wire carries 3.00 A of current in the same direction and is spaced apart by 6.00 cm.

Think of these two wires as being placed side by side on a table, with currents flowing in opposite directions toward you—wire 1 to the left and wire 2 to the right. The magnetic field produced by wire 1 at the location of wire 2 is directed vertically upward, according to the right-hand rule that links current to field direction. The force experienced by wire 2 as a result of its current flowing through this field is therefore determined by the right-hand rule, which links current and field to force, to be to the left, back toward wire 1. The force that one wire applies to another is therefore an attractive force.

Review. For a certain type of steel, stress is always proportional to strain with Young's modulus 20 × 10¹⁰ N/m² . The steel has density 7.86× 10³kg / m³. It will fail by bending permanently if subjected to compressive stress greater than its yield strength бy = 400MPa. A .rod 80.0cm long, made
of this steel, is fired at 12.0 m/s straight at a very hard wall.(d) the strain

Answers

The strain in the rod is [tex]2.37\times 10^{-3}[/tex]

Given:

Young's modulus, Y = [tex]20 \times 10^{10}\;N/m^{2}[/tex]

Steel density, [tex]\rho = 7.86 \times 10^{3}\;kg/m^{3}[/tex]

Length of the rod, L = 80 cm = 0.800m

The speed of the wave in the rod is,

[tex]$v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$[/tex]

Hence the time taken by the wave to travel the end of the rod is,

[tex]$t=\frac{L}{v} = \frac{0.800\ \mathrm{m}}{5044\ \mathrm{m/s}} = 1.58\times 10^{-4}\ \mathrm{s}$[/tex]

The velocity of the rod is, [tex]$v_r = 12.0\ \mathrm{m/s}$[/tex]

The other end will keep moving after the front end hits the wall until the wave reaches the other end, given the period determined by the above problem.

As a result, before the wave reaches the end of the rod, it has traveled a distance of

[tex]$\Delta L = v_r t = (12.0\ \mathrm{m/s}) (1.58\times\ \mathrm{s}) = 1.90\times 10^{-3}\ \mathrm{m} = 1.90\ \mathrm{mm}$[/tex]

The strain in the rod is given by,

[tex]$\frac{\Delta L}{L} = \frac{1.90\times 10^{-3}\ \mathrm{m}}{0.800\ \mathrm{m}} = 2.37\times 10^{-3}[/tex]

Hence, the strain in the rod is [tex]2.37\times 10^{-3}[/tex].

A solid sphere of radius 40.0cm has a total positive charge of 26.0μC uniformly distributed throughout its volume. Calculate the magnitude of the electric field(d) 60.0 cm from the center of the sphere.

Answers

The magnitude of the electric field for 60 cm is 6.49 × 10^5 N/C

R(radius of the solid sphere)=(60cm)( 1m /100cm)=0.6m

[tex]Q\;(\text{total charge of the solid sphere})=(26\;\mathrm{\mu C})\left(\dfrac{1\;\mathrm{C}}{10^6\;\mathrm{\mu C}} \right)={26\times 10^{-6}\;\mathrm{C}}[/tex]

Since the Gaussian sphere of radius r>R encloses all the charge of the sphere similar to the situation in part (c), we can use Equation (6) to find the magnitude of the electric field:

[tex]E=\dfrac{Q}{4\pi\epsilon_0 r^2}[/tex]

Substitute numerical values:

[tex]E&=\dfrac{24\times 10^{-6}}{4\pi (8.8542\times 10^{-12})(0.6)}\\ &={6.49\times 10^5\;\mathrm{N/C}\;\text{directed radially outward}}}[/tex]

The spherical Gaussian surface is chosen so that it is concentric with the charge distribution.

As an example, consider a charged spherical shell S of negligible thickness, with a uniformly distributed charge Q and radius R. We can use Gauss's law to find the magnitude of the resultant electric field E at a distance r from the center of the charged shell. It is immediately apparent that for a spherical Gaussian surface of radius r < R the enclosed charge is zero: hence the net flux is zero and the magnitude of the electric field on the Gaussian surface is also 0 (by letting QA = 0 in Gauss's law, where QA is the charge enclosed by the Gaussian surface).

two identical traveling waves, moving in the same direction, are out of phase by π/2 rad. what is the amplitude of the resultant wave in terms of the common amplitude ym of the two combining waves?

The amplitude of the resultant wave in terms of the common amplitude [tex]y_m[/tex] of the two combining waves which are out of phase by [tex]\frac{\pi}{2} \ \text{rad}[/tex] is [tex]\sqrt{2} y_m[/tex].

The amplitude of two waves interfering with each other depends on the principle of superposition.

Since, the waves are out of phase by [tex]\frac{\pi}{2} \ \text{rad}[/tex] so we can write the waves to be:

[tex]y_1=Asin(kx-\omega t)[/tex]

[tex]y_2=Asin(kx-\omega t+\frac{\pi}{2})\\ \therefore y_2=Acos(kx-\omega t)[/tex]

According to the principle of superposition, the resultant wave is written as:

[tex]y=y_1+y_2[/tex]

[tex]\Rightarrow y=A[sin(kx-\omega t)+cos(kx-\omega t)]\\\Rightarrow y=\sqrt{2}A[\frac{1}{\sqrt{2}}sin(kx-\omega t)+\frac{1}{\sqrt{2}}cos(kx-\omega t)]\\y=\sqrt{2}Asin(kx-\omega t+ \frac{\pi}{4})[/tex]

So from the above relation, we have the amplitude to be:

The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:

vx=v

The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:

Heresmy magic trick in action. Consider the fractions 519 and 623 . I multiply the numerator of the first andthe denominator of the second, and get 5 23 = 115. I multiply the numerator of the second and thedenominator of the first, and get 6 19 = 114. Because 115 > 114, I know that 519 >623 .Why does this magic trick work? In other words, if a, b, c, and d are positive, then why does ad > bcmean that ab>cd? (Problem 9.28 in the textbook, page 283)If you are stuck, Problem 9.3 in the textbook may help.4.
