when you jump, you accelerate upward because the floor exerts an upward force on you. (True or False)

Answers

Answer 1

This is an effective example of Newton's third law. Because of the upward push of the floor, you jump higher and faster. A force of 2,295.9 N is exerted on an airplane weighing 1,500 N while it is accelerated at 15 m/s2.

As we leap, the chemical energy in our muscles is transformed into kinetic energy, which exerts a force on the ground and, according to Newton's third law, causes a reaction that "pushes" us up—leading to the jump. Mass times leap distance equals the typical force that results. A person's center of mass may experience a force from their legs of 1200 N while moving 0.3 m upward during a jump. Gravity, which pulls everything down and causes the bungee jumper to fall, is the first force that the jumper encounters. Almost perfectly constant throughout the trip is the gravitational pull. The force of air resistance is another factor the bungee jumper encounters throughout the descent.

QuestionWhy is AC used for long distance power transmission instead of DC?AAC dissipates lower power than DC in a current carrying wireBIt is more convenient to step up/down voltage for AC than DCCPower dissipation in AC is lower since frequency is highDAC has lower risk of shock than DC

Answers

AC is used for long distance power transmission instead of DC because it is more convenient to step up/down voltage for AC than DC.

The risk of shock from a power source depends on the voltage, current, and resistance of the circuit. In a DC circuit, the voltage and current remain constant, so if there is greater resistance, the current will be higher, leading to a greater risk of shock. In an AC circuit, the voltage and current vary with frequency, so even at higher resistances, the current will remain lower. This means that there is less risk of shock compared to a DC circuit. For example, if there is a 10 ohm resistance in a DC circuit with 100V, the current will be 10A, resulting in 1000W of power dissipation. In an AC circuit with the same resistance and voltage, the current will be much lower because of the frequency of the waveform, resulting in less power dissipation and a lower risk of shock.

Are electron transport chain and oxidative phosphorylation the same process?

Answers

The electron transport chain and oxidative phosphorylation are closely related but are not the same process.

The electron transport chain and oxidative phosphorylation are two separate processes that occur during cellular respiration. The electron transport chain involves a series of electron carriers that transfer electrons from NADH and FADH2 to oxygen, creating a proton gradient across the mitochondrial inner membrane.

Oxidative phosphorylation, on the other hand, is the process by which ATP is synthesized using the energy from the proton gradient created by the electron transport chain.

While the electron transport chain and oxidative phosphorylation are closely related and dependent on each other, they are distinct processes that occur in different locations within the mitochondria. The electron transport chain occurs in the inner mitochondrial membrane, while oxidative phosphorylation occurs in the mitochondrial matrix.

is mass an intensive or extensive physical property?

Answers

Mass is an extensive physical property because it is dependent on the amount or quantity of matter present in a system.

Mass is a measure of the total amount of matter that is present in an object or substance, and it is directly proportional to the number of atoms or molecules that make up that object or substance.

Intensive properties, on the other hand, do not depend on the amount of matter present in a system. Examples of intensive properties include temperature, density, and specific heat. These properties remain constant regardless of the size or quantity of the sample.

In contrast, if you combine two objects, the total mass will be equal to the sum of the individual masses of the objects. This is what makes mass an extensive property. The more mass there is in a system, the more extensive the property becomes.

Therefore, mass is an essential parameter for describing many physical phenomena, such as momentum, energy, and force. It is an essential factor in the laws of physics, and it plays a crucial role in determining the behavior of objects in motion.

a student moves a distance of 4.0 m for 2.0 seconds. she then moves a distance of 1.0 m. i fthe total time she moved was 4.0 seconds, what was her velocity during the second time interval?

Answers

Answer:

Explanation:

We can use the formula for average velocity to calculate the student's velocity during the second time interval:

Average velocity = (final position - initial position) / time

During the first time interval, the student moved a distance of 4.0 m in 2.0 seconds, so her average velocity during that time was:

Velocity = 4.0 m / 2.0 s = 2.0 m/s

During the second time interval, the student moved a distance of 1.0 m, and the total time she moved was 4.0 seconds. Therefore, the time for the second interval was:

Time = Total time - First time interval = 4.0 s - 2.0 s = 2.0 s

We can now use the formula for average velocity again to calculate the student's velocity during the second time interval:

Average velocity = (final position - initial position) / time

Velocity = 1.0 m / 2.0 s = 0.5 m/s

Therefore, the student's velocity during the second time interval was 0.5 m/s.

Answers

Initial speed of the mug was approximately 3.34 m/s, which is option E. We use conservation of energy.

To solve this problem, we can use the conservation of energy principle to relate the initial speed of the mug to its final position after sliding off the counter.

When the mug slides off the counter, it has some potential energy due to its height above the base of the counter, and some kinetic energy due to its motion. When it lands on the floor, it has lost all of its potential energy but gained some additional kinetic energy due to the work done by gravity.

Let's assume that there is negligible air resistance during the motion of the mug. Then we can use the conservation of energy principle to write:

[tex]mgh + (1/2)mv^2 = (1/2)mv_f^2[/tex]

where m : mass of the mug, g : acceleration due to gravity, h : height of counter, v : initial speed of mug, and v_f : final speed of mug before landing on floor

Since the mug slides off the counter horizontally, it has constant horizontal velocity throughout motion. We use the horizontal distance traveled by the mug to find time of flight:

d = v_f t

d : horizontal distance traveled, and t: time of flight.

Utilize time of flight to calculate final speed of mug before landing:

[tex]h = (1/2) g t^2 = > t = sqrt((2h)/g)v_f = d / t = (d / sqrt((2h)/g))[/tex]

Substitute v_f into conservation of energy eqn and find v:

[tex]mgh + (1/2)mv^2 = (1/2)mv_f^2mgh + (1/2)mv^2 = (1/2)md^2 / t^2[/tex]

Substituting values:

[tex]mgh + (1/2)mv^2 = (1/2)md^2 g / (2h)[/tex]

Simplifying and solving for v, we get:

[tex]v = sqrt((2gh)/3) * sqrt(1 + 2d^2/(3h^2))[/tex]

Put values:

v = [tex]\sqrt{ ((2 * 9.81 m/s^2 * 0.86 m)/3)} * \sqrt{(1 + 2 * (1.4 m)^2 / (3 * (0.86 m)^2))}[/tex]

The adiabatic exponent for monoatomic gases is 0.66. So,

   T₂/T₁ = (0.125)⁰⁶⁶⁻¹

⇒ T₂/T₁ = (0.125)⁰°⁶⁵

⇒ T₂/T₁ = 0.25

As a result, the temperature rises by a factor of ten in this procedure 0.25 .We know that V(rms) is proportional to √T. so we have

[tex]\frac{V_rms_1}{V_rms_2}[/tex] = [tex]\sqrt{\frac{T_2}{T_1} }[/tex] = √0.25 = 0.5

i.e. The rms speed increases by a factor of 0.5.

b. The mean free path is given by in the book

λ = [tex]\frac{V}{4\sqrt{2}\pi Nr^{2} }[/tex]

where

r is The effective radius of the molecule,

V is the volume of the gas and

N is the number of molecules.

All quantities in the λ formula except volume are constant in this process.

Since, λ ∞ ∨ decreases by a factor of 0.5, also decreases by a factor of 0.5.

C. A monoatomic gas's thermal energy is given by

[tex]E_th[/tex] = [tex]_nC_vT[/tex]

Both the number of moles  n , and ,

the molar specific heat at constant volume [tex]C_v[/tex] are constant in this process so the only thing that changes is the temperature.

Since [tex]E_th[/tex] ∞ T since we have found that the temperature increases by a factor of 0.25 then [tex]E_th[/tex] also increases by a factor of 0.25 .

d. The molar specific heat of a monoatomic gas is just a constant equal to [tex]C_v =[/tex] 0.5R.

So, it doesn't change in this process.

Therefore,

The rms speed of the system is 0.25 while Mean free path is 0.5 times the first mean free path.
