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.

Answer:

Because a person may be pulled in the direction of the moving train. Thereby causing accident

Explanation:

According to Daniel Bernoulli's theorem, he was widely known as a Mathematician. He stated that due to the higher velocity of a moving train, there is higher kinetic energy in terms of volume around it, while the air pressure between the person and the train becomes lower.

As a result, a person near a moving train may be pulled in the direction of the moving train. Thereby causing accidents that may lead to death.

Answer:

a)  F₃ = 109.5 N ,     θ₃ = 38.35,  b)   m = 0.429 kg

Explanation:

For this force addition exercise, let's decompose the forces into a coordinate system

strength 1

          cos 70 = F₁ₓ / F₁

          sin 70 = [tex]F_{1y}[/tex] / F₁

          F₁ₓ = F₁ cos 70

         F_{1y} = F₁ sin 70

          F₁ₓ = 45 cos 70 = 15.39 N

          F_{1y} = 45 sin70 = 42.29 N

Strength 2

         cos 20 = F₂ₓ / F₂

         sin 20 = F_{2y} / F₂

         F₂ₓ = F₂ cos 20

         F_{2y} = F₂ sin20

         F₂ₓ = 75 cos 20 = 70.48 N

         F_{2y} = 75 sin 20 = 25.65 N

a) in the first part we are asked to find the magnitude of force 3 so that the body is in equilibrium

X axis

         ∑ Fₓ = 0

          F₁ₓ + F₂ₓ + F₃ₓ = 0

          F₃ₓ = - F₁ₓ - F₂ₓ

          F₃ₓ = - 15.39 - 70.48

          F₃ₓ = - 85.87 N

Y Axis

         ∑ F_{y}  = 0

         F_{1y} + F_{2y} +F_{3y}  = 0

         F_{3y} = - F_{1y} -F_{2y}

         F_{3y} = - 42.29 - 25.65

         F_{3y} = - 67.94 N

the magnitude of this force can be found using the Pythagorean theorem

         F₃ = √ (F₃ₓ² + F_{3y}^2)

         F₃ = √ (85.87² + 67.94²)

         F₃ = 109.5 N

The direction of this force can be found using trigonometry

          tan θ =  F₃ = [tex]F_{3y}[/tex] / F₃ₓ

          θ₃ = Tan⁻¹ (67.94 / (85.87))

          θ₃ = 38.35º

since the two vectors are negative this angle is in the third quadrant, measured from the positive side of the x axis is

          θ₃ = 180 + 38.53

          θ₃ = 218.35º

b) I think you have an error in your statement, we have two possibilities:

1) If we eliminate the third force, what is the mass

it should say: "if we apply the third force force ...", they ask that we find the masses of the vehicle, let's use Newton's second law

X axis

       F₁ₓ + F₂ₓ = m a

       15.39 + 70.48 = m 200

        m = 85.87 / 200

        m = 0.429 kg

2) If the force F3 is in the first quadrant

        F1x + F2x + F3x = m a

        m = (15.39 + 70.48 + 85.87) / 200

        m = 0.8587 kg

The discharge rate of water (Q) that flows across the exit of the pipe in 1.00 seconds is 0.200 [tex]m^3/s[/tex].

Given the following data:

To find the discharge rate of water (Q) that flows across the exit of the pipe in 1.00 seconds assuming that Bernoulli's equation applies:

In this exercise, we would apply Torricelli's Law, which states that the speed of the efflux in an apparatus, under the force of gravity is directly proportional to the square root of the height of the fluid above it.

Mathematically, Torricelli's Law is given by the formula:

[tex]V =\sqrt{2gh}[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]V =\sqrt{2 \times 9.8 (10-2)}\\\\V =\sqrt{19.6 (8)}[/tex]

Speed, V = 12.52 m/s

Now, we can find the discharge rate of the pipe:

[tex]Q = V \times A\\\\Q = 12.52 \times 1.60\times 10^{-2}[/tex]

Discharge rate, Q = 0.200 [tex]m^3/s[/tex]

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. one line down one line to the right one live to the northwest from the object

b. t1=190 t2=310

Explanation:

The torque would be 240 Nm

Coefficient of Kinetic Friction = 0.2

Mass of the crate = 1000 kg

Force applied = 2000 N

Normal force is the force applied on the object by the surface. It is equal and opposite to the force of gravity

So, we can say that Normal force = | Gravitational Force |

Normal Force = | mg |

Normal Force = 1000 * 9.8

Normal Force = 9800 N

We know that:

coefficient of Kinetic friction = Friction force / Normal force

replacing the known values

0.2 = Friction force / 9800

Friction Force=  0.2 * 9800

Friction Force = 1960 N

We know that a force of 2000 N is being applied on the crate in the Horizontal direction

Frictional force is always opposite to the horizontal force. So, we can say that:

Applied force - Friction Force = Net Force

replacing the variables

2000 - 1960 = Net force

Net Force = 40N

Therefore, a net force of 40N is being applied on the Crate

From newton's second law of motion:

F = ma

replacing the variables

40 = 1000 * a

a = 40/1000

a = 0.04 m/s²

Hence, the crate will have an acceleration of 0.04 m/s²

Explanation:What Gives Rise To The Potential Difference Between The Extracellular Fluid ... is much smaller than the resistance of the current path through the axoplasm.

Neurons in the axoplasm is acting like a leaky cable and its resistivity increases with length. The axon membrane will transfer the ions to te organelle called axolemma and thus the resistance of current path is more for axoplasm.

The cytoplasm found inside a neuron's axon is called axoplasm . This may account for more than 99% of the cytoplasm in some types of neuronal cells .

Organelles and other components of the axoplasm are different from those of the dendrites and cell body (soma) of the neuron. Materials are transported to or from the soma through the axoplasm during axonal transport, also referred to as axoplasmic transport.

One characteristic of a neuron's cable is its electrical resistance, or axoplasmic resistance, which influences how quickly an action potential travels down an axon.

The potential will move more slowly if the axoplasm contains a lot of molecules that are not electrically conductive because more ions will pass through.

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.
