Which illustration represents the arrangement of particles in a liquid?

Answer: Because the human body is designed to use their muscles to create and transfer things from place to place, and that some man-made objects are light enough to be moved..?

Answer:

c it is not accelerating on it's on but gravity pulls it there for velocity increases.

As an object falls, velocity increases and acceleration is unchanged. Therefore, option C is correct.

The term velocity is defined as the direction of the movement of the body or the object.

Speed is fundamentally a scalar quantity. Velocity is, in essence, a vector quantity. It is the rate at which distance changes. It is the displacement rate of change.

The velocity of something is the rate at which it moves in a specific direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch. The scalar denotes that the absolute magnitude of the velocity vector is always the speed of motion.

Thus, it is not accelerating on it's on, but gravity pulls it there as velocity increases.

Answer:

A, the objects velocity

Explanation:

Answer:

a) The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

Explanation:

a) The vectorial equation of momentum is represented by the following expression:

[tex]\vec p = m\cdot \vec v[/tex] (1)

Where:

[tex]\vec p[/tex] - Vector momentum, measured in kilogram-meters per second.

[tex]m[/tex] - Mass of the particle, measured in kilograms.

[tex]\vec v[/tex] - Vector velocity, measured in meters per second.

If we know that [tex]m = 2.93\,kg[/tex] and [tex]\vec v = 2.98\,\hat{i}-3.98\,\hat{j}\,\,\,\left[\frac{m}{s} \right][/tex], then the momentum is:

[tex]\vec p = (2.93)\cdot (2.98\,\hat{i}-3.98\,\hat{j})\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

[tex]\vec p = 8.731\,\hat{i}-11.661\,\hat{j}\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of momentum are represented by the following expressions:

[tex]\|\vec p \| = \sqrt{p_{x}^{2}+p_{y}^{2}}[/tex] (2)

[tex]\theta = \tan^{-1}\left(\frac{p_{y}}{p_{x}} \right)[/tex] (3)

Where:

[tex]\|\vec p\|[/tex] - Magnitude of momentum, measured in kilogram-meters per second.

[tex]\theta[/tex] - Direction of momentum, measured in sexagesimal degrees.

If we know that [tex]p_{x} = 8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]p_{y} = -11.661\,\frac{kg\cdot m}{s}[/tex], then the magnitude and direction of momentum are, respectively:

[tex]\|\vec p\| = \sqrt{\left(8.731\,\frac{kg\cdot m}{s} \right)^{2}+\left(-11.661\,\frac{kg\cdot m}{s} \right)^{2}}[/tex]

[tex]\|\vec p\| \approx 14.567\,\frac{kg\cdot m}{s}[/tex]

[tex]\theta =\tan^{-1}\left(\frac{-11.661\,\frac{kg\cdot m}{s} }{8.731\,\frac{kg\cdot m}{s} } \right)[/tex]

[tex]\theta \approx 306.823^{\circ}[/tex]

The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

Answer:

8 kg*m/s and 2m/s

Explanation:

momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.

4kg*12m/s = 48 kg*m/s

4kg*10m/s = 40 kg*m/s

48kg*m/s - 40 kg*m/s = 8kg*m/s

Answer: e. P/2

Explanation:

For ideal gases, we have the relation:

P*V = n*R*T

where:

n =  number of mols

R = Gas constant

T = temperature

V = volume

P = pressure.

We know that for sample A, we have n moles, a temperature T and a volume V, then the pressure of this sample will be:

Pa = (n*R*T)/V.

For sample B, we have:

n/2 moles, temperature T/2 and a volume V/2, then the pressure will be:

Pb = (n/2)*R*(T/2)*(2/V) = (n*R*T/V)*(2/4)

and:

(n*R*T/V) = Pa

Then we can replace it and we get:

Pb = (n*R*T/V)*(2/4) = Pa*(2/4) = Pa*(1/2) = Pa/2.

Then the correct option is e.

Answer:

B. Shear Modulus

Explanation:

In this scenario, the friction force between the sliding block and the floor causes the block to deform.

Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.

Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.

This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.

Mathematically, Shear Modulus is given by the formula;

[tex] G = \frac {Fl}{ADx} [/tex]

Where;

G is the Shear Modulus.

F is the force applied to the object.

A is the area of the object.

l is the length of the object.

Dx is the change in length.

Shear Modulus is measured in Pascals.

Force = Mass × Acceleration

Mass = 2.5 kg

Answer:

6.9m/s

Explanation:

Given parameters:

Acceleration of the object  = 4m/s²

Distance = from x; 2m to x; 8m

Unknown:

Average velocity  = ?

Solution:

From the given parameters, we use the right motion equation to solve the problem.

   v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

 S is the distance covered

 Distance  = 8m - 2m  = 6m

 Initial velocity  = 0m/s

The final velocity gives us the average velocity in this problem;

       v² = 0² + (2 x 4 x 6) = 48

      v = √48  = 6.9m/s

Answer:

V/Ve = 1.1

Explanation:

The formula to find the escape velocity of an object at a distance from Earth's Surface is given as follows:

Ve = √[2GM/R]

where,

Ve = escape velocity = ?

G = Universal Gravitational  Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Earth = 5.97 x 10²⁴ kg

R = Radius of Earth = 6.37 x 10⁶ m

Therefore,

Ve = √[2(6.67 x 10⁻¹¹ N.m²/kg²)(5.97 x 10²⁴ kg)/(6.37 x 10⁶ m)]

Ve = 11.2 x 10³ m/s = 11.2 km/s

Hence, the ratio will be:

V/Ve = (12.3 km/s)/(11.2 km/s)

V/Ve = 1.1

Explanation:

In an inelastic collision, the momentum remains conserved while the kinetic energy is not conserved.

(i) Here, a small sports car runs into the machine from behind.

Due to the conservation of momentum, it remains conserved. It means their momentum changes are the same size.

Hence, the correct option is (c).

(ii) The car is moving faster than the tractor. A faster moving object will lose more energy as compared to the other. It means car's most of the energy is converted to internal energy. The car will have a a larger change in kinetic energy. Hence, the correct option is (a).

A cell phone more likely to break when dropped from a higher height than a lower one because it has more potential energy at high height.

Potential energy is the energy stored by an object as a result of its position relative to other objects, internal tensions, electric charge, or other reasons.

Potential energy is commonly defined as an object's gravitational potential energy, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The joule is the SI unit of energy.

Although it has connections to the Greek philosopher Aristotle's concept of potentiality, the word potential energy was coined by the 19th-century Scottish engineer and physicist William Rankine.
