Answer:

a) The pressure in a traveling sound wave is given by the equation

p Pa π m x s t − − Δ = −

s x, t 6.0 nm cos kx+ 3000 rad / s t+ ( )( ) ( ) ( )

Find the (a) pressure amplitude, (b) frequency, (c) wavelength,

and (d) speed of the wave.

b) If the form of a sound wave traveling through air is

= ϕ , how much time does any given air molecule along

the path take to move between displacements s = + 2.0 nm and s = - 2.0 nm?

Solution: (a) The amplitude of a sinusoidal wave is the numerical coefficient of the sine (or

cosine) function: pm = 1.50 Pa.

We identify k = 0.9π and ω = 315 π (in SI units), which leads to f = ω /2 π = 158 Hz.

We also obtain λ = 2π/k = 2.22 m.

The speed of the wave is v = λ /k = 350 m/s.

(b) Without loss of generality we take x = 0, and let t = 0 be when s = 0. This means the

phase is φ= -π/2 and the function is s = (6.0 nm)sin(ωt) at x = 0. Noting that ω = 3000 rad/s,

we note that at t = sin-1(1/3)/ω = 0.1133 ms the displacement is s = +2.0 nm. Doubling that

time (so that we consider the excursion from –2.0 nm to +2.0 nm) we conclude that the time

required is 2(0.1133 ms) = 0.23 ms.

1. What are three things you think of when you think of energy?

Answers

Answer:

Food, wind, water.

Explanation:

This is supposed to be a personalized question so I answered with things that can make/give energy.

Answer:

This is personal question, very interesting! Depend on who is the person, where the person is working at, how old is that person - we can have various answers.

Personally, I think first about that human and other animals needs energy to survive, that means we need to eat, to drink; The plants need energy to survive too - that is the energy from the Sun.

Secondly, the human being needs such types of energy as electricity, wind, solar energy, etc. in oder to live. Even the acient people learnt to use solar and wind and water - natural energy from the nature.

Thirdly, the human being needs spiritual energy to have a good life.

Another specific terms of energy related to physics and chemistry, and even biology - actually are not in my mind in everyday life.

Explanation:

A 200-kg boulder is 1000-m above the ground. what is its potential energy?

Answers

Explanation:

PE = mgz = 200 * 9.81 *1000 = 1962 KJ

A 200-kg boulder is 1000-m above the ground. 1962 KJ is its potential energy.

What is potential energy ?

The term potential energy is defined as the stored energy that depends upon the relative position of various parts of a system. Because it has a potential to do work when released it is called as potential energy.

A spring has more potential energy when it is stretched. Any object that is stretched from its resting position has stored energy, so it is called potential energy.

The SI unit of electric potential is represented by volt (V), and it can also be written as Joule per Coulomb. The unit of potential energy is joules.

Potential energy = mgz

= 200 × 9.81 × 1000

= 1962 KJ

Thus, A 200-kg boulder is 1000-m above the ground.  1962 KJ is its potential energy.

Which of the following is NOT an important component of planning ahead?

C. constructing an inflexible plan
D. deciding what you want to accomplish

Answers

Answer: B setting plausible limits

Explanation: because when you are planning ahead you must only think how to do the thing correctly if you do all of your steps correctly you won't have any limitations.

Answer:

The correct answer is constructing an inflexible plan.  Planning is a huge part in an individual’s life and also the life of a company. Though we want to plan for everything that could possibly happen, there needs to be flexibility as situations can change. Due to the fact planning can have a positive affect on a business for future happenings, it must also have variable and flexible room incase there are changes that need to be made.

Identify the following equation: H2 - 2H+ + 2e
A. oxidation
B. reduction
C. redox
D. none of the above

Answers

Answer:

(A.) H2 --> 2H+ 2 e- (oxidation)

Explanation:

A. oxidation is the removal of electron(s) from a substance. This is the case here, since AFTER the reaction you can see that there were electons "removed" from H2.

H2 --> 2H+ 2 e- (oxidation)

B. reduction is the addition of electron(s) to a substance

1/2 O2 + 2 e- + 2H+ --> H2O (reduction)

By the way:

Biochemical reactions often involve the transfer of complete hydrogen atoms, meaning an electron and a proton.

The substance oxidized (H2) is electron donor.

The substance reduced (O2) is electron acceptor.

Just remember this:

Prior to the reaction, the e donor is always reduced.

Prior to the reaction, the e acceptor is always oxidized.

What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?​

Answers

KE = 0.5 x mv^2

Kinetic energy equals 1/2 times mass times velocity squared.

Mass = 15kg

Velocity = 3m/s

Plug it into the formula.

KE = 0.5 x 15(3^2)

KE = 0.5 x 15(9)

Multiply the mass and velocity squared.

KE = 0.5 x 135

Then, multiply the result by 1/2 or 0.5

KE = 67.5

The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.

Answer:

67.5 J

Explanation:

Kinetic energy can be found using the following formula.

[tex]KE=\frac{1}{2}mv^2[/tex]

where m is the mass in kilograms and v is the velocity in m/s.

We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v

[tex]KE=\frac{1}{2}*15*3^2[/tex]

Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.

[tex]KE=\frac{1}{2} *15*9[/tex]

Multiply 15 and 9.

[tex]KE=\frac{1}{2} *135[/tex]

Multiply 1/2 and 135

[tex]KE=67.5[/tex]

Add appropriate units. Kinetic energy uses Joules or J as the units.

[tex]KE= 67.5 Joules[/tex]

The kinetic energy of the bike is 67.5 Joules
