Peace and violence are the indicators of the society.

Respect is shown if we see a people as a person and not as a toy. If we stop  criticizing and judging by just looking at them than the other person also gives us respect which leads to peace and harmony in the society.

If there is discrimination and no respect of other people's feeling then there is violence and disharmony in the society so we can conclude that peace and violence are the indicators of the society.

Explanation:

The characteristic of an atom is as follows:

Thus, the correct option for this question is D.

An atom may be defined as a particle of matter that uniquely defines a chemical element. Each and every atom consists of a central nucleus that holds positively charged subatomic particles known as Protons along with neutrons.

Apart from protons and neutrons, the negatively charged subatomic particles known as electrons are always revolved around the nucleus of each atom in its orbitals.

According to the context of this question, an atom is the smallest unit of matter which significantly retain all the chemical properties of an element. Thus, the second option is eliminated. They are naturally present not made in stars. So, the option third is also eliminated.

Therefore, the correct option for this question is D.

Explanation:

If we are to assume that the plane is at the bottom of a circular movement and just about to depart in level flight, then

(39.34 - 9.81) = 600²/R

R = 12,190.992211... m

Which is very close to the 1.2 km option

Answer:          T = 93 N

Explanation:

Assuming the pulley is ideal meaning frictionless as mentioned and also negligible mass.

         ΣF = Σma

Mg - mg = Ma + ma

           a = g(M - m) / (M + m)

Now looking only at the larger mass as it falls

Mg - T = Ma

       T = Mg - Ma

       T = Mg - Mg(M - m) / (M + m)

       T = Mg(1  -(M - m) / (M + m))

       T = 16(9.8)(1 - (16 - 6.7) / (16 + 6.7))

       T = 93 N

or looking only at the smaller mass

T - mg = ma

T = m(g + a)

T = m(g +  g(M - m) / (M + m))

T = mg(1 +  (M - m) / (M + m))

T = 6.7(9.8)(1 +  (16 - 6.7) / (16 + 6.7))

T = 93 N

The particles can undergo small oscillations around x₂.

The given parameters;

The movement of the particles depends on the kinetic energy of the particles.

When kinetic energy of the particles is 100%, the particles can oscillate from x₁ to x₅.

However, when the total energy of this particles is reduced to one-third (¹/₃) or 33% of the initial energy of the particle, the oscillation of the particles will be reduced.

Since 33% is less than the half of the energy of the particle, the particle will oscillate between x₁ and x₂.

Thus, we can conclude that the particles can undergo small oscillations around x₂.

Answer:

Below

Explanation:

c) To find the time of flight of a projectile (assuming from the given information that there is no vertical displacement) you can use this formula :

     t = 2(Vi) Sinx / g

     t = 2(51.5m/s) Sin(4) / 9.8 m/s^2

     t = 0.733 seconds

    t = 0.73 seconds

d) To find the displacement in the x-direction you can use this formula :

     dx = vi^2 sin(2x) / g

     dx = (51.5m/s)^2 sin(2(4)) / 9.8m/s^2

     dx = 37.6654 m  

     dx = 37.7 meters

e) To find the peak height of the projectile you can use this formula :

     v^2sin^2(x) = 2gh

     (51.5m/s)^2sin^2(4) = 2(9.8m/s^2)h

     h = 0.658 meters

     h = 0.66 meters

Answer:

F = - K X     force exerted by compressed spring

F X = 1/2 M V^2    energy (work) required to produce a speed V for mass M

K X * X  = 1/2 M V^2      direction of F is the same as that of V

X^2 = M V^2 / K      combining  terms

X = (M / K)^1/2 V      

X = (.92 / 130)^1/2 * 1.4 = .118 m

Answer:

By Charles Law the volume of 1 cm^3 at standard conditions is

V = V0 * 273 / 293 = 1 cm^3 * .932 cm^3

Reducing the temperature to 0 deg C results in a volume of .932 cm^3

1 mole of gas contains 22.4 L of gas

1 L = 1000 cm^3

1000 cm^3 / L / (.932 cm^3 / container) = 1073   containers / L

So 1 mole of gas = 1073 containers * 22.4 L /container =  24,305 L

6.02E23 molecules / mole * 1 / 24305 molecules / mole = 2.48E19

number of molecules present = 2.48 * 10^19

(Easier to calculate volume of 1 cc

1 cc = 6.02E23 / (1000 * 22.4) = 2.69E19 molecules in 1 cc

Vol of 1cc = 273 / 293 = .932

2.69E19 * .932 = 2.51 * 10^19)

Explanation:

Assuming that there is no air resistance, the given time means that the ball reached its maximum height 3 seconds after throwing it upwards so we can solve its

Hi there!

We know that the MAXIMUM static friction force to be overcome is:

Fs (Force of Static Friction) = μN (Normal Force)

The normal force is equal to the weight of the block AND the vertical component of the applied force, so:

N = Mg + Fasinθ

Plug in the given values:

N = 26.8(9.81) + (89.2)sin(38) = 317.825 N

Multiply by the force of static friction to derive the static force:

0.74 * 317.825 = 325.191 N <-- MAXIMUM STATIC FRICTION FORCE

The force applied, if not greater than this value, will result in an EQUAL and OPPOSITE static frictional force. Thus:

Fs = Horizontal component of the applied force

Fs = 89.2cos(38) = 70.291 N

Explanation:

For these types of questions, you should draw out your triangles and resultant vectors.

For this, we can use the pythagorean theorem to solve this :

     vpf^2 = vpi^2 + vw^2

     vpf^2 = 45^2 + 191^2

     vpf = [tex]\sqrt{38507[/tex]

     vpf = 196.2294

     vpf = 200 mph

Now we need to find the angle of the plane's direction using soh cah toa

     Tan(x) = O / A

              x = tan^-1(191/45)

              x = 76.74

              x = 77 degrees

Therefore, the plane's result velocity is 200 mph [ E 77 N ]

Answer:

0.788 m/s²

Explanation:

Ff = 0.1 × 5 kg × 10 m/s² × cos 38°

Ff = 5 N × 0.788

Ff = 3.94 N

F = m × a

3.94 N = 5 kg × a

a = 3.94 N / 5 kg

a = 0.788 m/s²
