a car collision where the cars stick togethera ball of sticky tape hitting a billiard ball\two bowling balls of equal masstwo steel cubes on a friction-less surface (no energy loss)

Elastic collision

An elastic collision is one in which there is no loss of kinetic energy. Both kinetic energy and momentum are conserved.

In general, a collision is not elastic if energy is dissipated as sound, light, heat, or deformation of material.

Choices

Of the offered choices, the first two (car collision, sticky tape collision) will result in deformation of one or more of the colliding objects. That deformation dissipates energy, so the kinetic energy after the collision will be different from before the collision.

The collision of (C) bowling balls, and (D) steel cubes are elastic collisions. Neither results in deformation of the colliding objects.

__

Additional comment

Clearly, any sort of collision can be engineered with enough starting energy to cause the colliding objects to disintegrate. Here, we're primarily concerned with collisions that allow the integrity of the colliding objects to be maintained (except in crashed cars).

The collisions are more or less assumed to be "ideal" in that there is no significant energy loss due to sound or vibration of the objects involved.

Answers

The corresponding tensile stress in the splice is 1240 kPa.

What is tensile stress?

Tensile stress is a type of mechanical stress that occurs when an object is pulled or stretched. It is the opposite of compressive stress, which occurs when an object is pushed or compressed.

Given:
Maximum allowable shearing stress in the glued splice, τ_allowable = 620 kPa.
(a) Largest load P that can be safely applied:
The maximum loading capacity of a scarf joint is determined by the allowable shear stress, τ_allowable. The load P is related to the maximum allowable shear stress by the following equation,
P = 2Aτ_allowable
where A is the cross sectional area of either member of the joint.
Therefore, P = 2*A*τ_allowable
= 2*A*620 kPa
= 1240 A (kN)
Hence, the largest load P that can be safely applied is 1240 A (kN).
(b) Corresponding tensile stress in the splice:
The tensile stress in the splice is related to the load P and cross sectional

Answers

According to the problem the molecular weight of air in this process is 0.8316 g.

What is molecular weight?

Molecular weight is a measurement used to describe the mass of an individual molecule. It is expressed in daltons (Da) or atomic mass units (amu). It is calculated by adding together all of the atomic masses of the atoms that make up the molecule.

The first law of thermodynamics states that the change in the internal energy of a system is equal to the heat added to the system plus the work done on or by the system.
Since there is no work being done in this process, we can write:
$\Delta U=Q$
We can calculate the change in internal energy using:
$\Delta U=nC_v\Delta T$, where $n$ is the number of moles and $C_v$ is the specific heat capacity at constant volume.
We can calculate $n$ using:
$n=PV/RT$, where $P$ is pressure, $V$ is volume, $R$ is the universal gas constant, and $T$ is temperature.
At state 1, n = (3 bar)(0.2 m3)/[(8.31 J/mol K)(350 K)] = 0.0099 mol
At state 2, n = (5 bar)(0.6 m3)/[(8.31 J/mol K)(350 K)] = 0.0297 mol
The molecular weight of air can be calculated as follows:
Molecular weight of air = 28 g/mol x n (moles) = 28 g/mol x 0.0297 mol = 0.8316 g

which of the following are responsible for the repulsive force between two identically charged atoms?

Answers

B: Electrostatic force is responsible for the repulsive force between two atoms charged identically.

The electrostatic force is an attractive force as well as a repulsive force induced by the electric charge particles. The electrostatic force is also called Columb's force. The Columb attraction would be named after Charles-Augustin de Coulomb, a French scientist. One of nature's four basic forces however is electrostatic force.

Between two charges placed at a distance, there exists the electrostatic force. The magnitude of the electrostatic force relies on the magnitude of each charge and the distance between them. When two identically charged objects (both with positive charges or both with two negative charges) are brought together, then the same charges repel each other.

What is meant by weight?

A force is weight. The Newton is the metric unit of force, and it moves at a speed of 1 metre per second2.The gravitational force that pulls a body toward the earth or another celestial body; it is equal to the mass multiplied by the local gravitational acceleration.Weight is the gravitational force that pulls objects toward the centre of the Earth. The resulting force that pulls a mass toward Earth is known as gravity. In contrast to gravitational force, which occurs between any two masses, this only occurs between Earth and a mass.Weight, which is expressed in newtons, is a unit of measurement for the gravitational force acting on an object.

Two balls, of masses m and 2m, travelling in a vacuum with initial velocities 2v and v
respectively, collide with each other head-on, as shown.

Initial,
mass m, velocity 2v to the right
mass 2m, velocity v to the left

After the collision, the ball of mass m rebounds to the left with velocity v.
What is the loss of kinetic energy in the collision?

Answer: 3/2mv^2

Answers

After the collision, the ball of mass m rebounds to the left with velocity v.

9/4mv² is the loss of kinetic energy in the collision.

What is collision?

When two bodies such as two pool cues, a golf club and a ball, a hammer and a nail, two railroad cars when connected, or a falling object and a floor abruptly and violently collide, this is referred to as a collision, also known as an impact.

What is kinetic energy?

The energy of motion, or kinetic energy, can be observed in the movement of an item or a subatomic particle. Every moving object and individual particle contains kinetic energy. When something moves, like when a person walks, a baseball flies, a piece of food falls off a table, or a charged particle moves in an electric field, it is exhibiting kinetic energy.

initials : m 1 =m ,m 2=2m,u1=2v,u 2 =−v

after collision: v 1 =−v

using conservation of linear momentum:

m1u1+m2u2=m1v1+m2v2

2mv−2mv=−mv+2mv2

v2 = V/2

Initial kinetic energy=m1 u²₁/2+ m2 u²₂/2= 3mv²

Initial kinetic energy=m1 v²₁/2+m2 v²₂/2 = 3/4 mv²

loss in Kinetic Energy=InitialKE−FinalKE

9/4mv²/2 = 3/2mv²

Therefore, collision, the ball of mass m rebounds to the left with velocity v. 9/4mv² is the loss of kinetic energy in the collision.

Find the following for path D in Figure 2.59:
(a) The distance traveled. (b) The magnitude of the displacement from start to finish. (c) The displacement from start to finish.
Answer choise:
A. 8 m
B. 4 m
C. -4 m

Answers

(a) A total distance of 8 + 4 = 12 metres. (b) The displacement of C is 8m in magnitude. (c) The displacement is (8m)i from beginning to end.

a) Point The first step of C's journey begins at x=2 and ends at x=10, covering a distance of (10-2) = 8m. In the second step, C travels to x=8 and returns to x=10m. A distance of 2 is equal to 2 * (20-8) = 4 metres.

= 8+4=12 metres is the total distance travelled.

b) The displacement is the distance between two locations in a figure that is the shortest. In the example in the picture, C begins its journey at x=2m and ends at x=10m; the distance between these two points is (10-2) = 8m, therefore the displacement of C is 8m.

C) We now understand that the displacement has a magnitude of 8m and a direction parallel to the positive x-axis.

From beginning to end, there is a (8m)i displacement.
