How does energy move in relation to the medium in a longitudinal wave?

Answer:

736.2

Explanation:

Work = mass * gravity * height

W = m * g * h

W = 6.26 * 9.8 * 12

W= 736.176 Joules

Rounding to 736.2.

Answer:

[tex]\boxed {\boxed {\sf v \approx 33.088 \ mL}}[/tex]

Explanation:

The formula for density is:

[tex]d= \frac{m}{v}[/tex]

where m is the mass and v is the volume.

The mass is 0.45 kilograms and the density is 13.6 grams per milliliter. The density is given in grams, so we must convert the mass.

There are 1000 grams in 1 kilogram or [tex]\frac{1000 \ g} {1 \ kg}[/tex]. We can multiply the mass by this ratio.

[tex]0.45 \ kg * \frac{1000 \ g} {1 \ kg} = 0.45 * 1000 \ g = 450 \ g[/tex]

Now we have values for the mass and density:

[tex]13.6 \ g/mL =\frac{450 \ g}{ v}[/tex]

Cross multiply.

[tex]\frac {13.6 \ g/mL}{1} =\frac{450 \ g}{ v}[/tex]

[tex]13.6 \ g/mL * v=450 \ g * 1 \\13.6 \ g/mL * v=450 \ g[/tex]

We are trying to find the volume, so we must isolate that variable.

13.6 and v are being multiplied. The inverse of multiplication is division. Divide both sides by 13.6

[tex]\frac {13.6 \ g/mL*v } { 13.6 \ g/mL} = \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

[tex]v= \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

The grams will cancel.

[tex]v= 33.0882353 \ mL\\v \approx 33.088 \ mL[/tex]

The volume is about 33.088 milliliters.

Answer: 0

Explanation: Work is force times displacement so although you're exerting a force on the chair since your not moving there is no displacement and anything times a value of zero is zero

Given parameters:

Mass of frisbee  = 5kg

Final speed  = 12m/s

Unknown:

Impulse of the frisbee  = ?

Solution:

The impulse of the frisbee is the same as the change in momentum.

It is given as:

 Impulse  = mass (Final velocity  -  Initial velocity)

 Impulse  = 5(12  - 0)  = 60kgm/s

Attached is a picture of a chocolate bar that can be easily found on the market. In this picture, we see the table of contents with the amount of energy that depends on the mass in grams of the chocolate bar.

We see that for the bar size of 100G, the energy value is 483 [kcal].

We can see that the energy depends on the size of the chocolate bar.

I'm assuming you were asking for the last question on the Calorimetry gizmo.

Answer: D=pg

Explanation:

?????

15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.

The measurement of pressure in relation to atmospheric pressure is known as gauge pressure. The zero point for this pressure measurement is set at 1 atm. With relation to atmospheric pressure, pressure is measured.

When a car climbs a mountain, the gauge pressure rises as the air pressure falls, but the tire's absolute pressure stays the same, assuming no tire leaks.

guage pressure = mass×height

                          = 30×5

                         =15 mm Hg

Therefore, 15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.

Answer: 21 kg x m/s

Momentum can be found using the equation p = mv, or momentum = mass times velocity.

Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)

Solve the equation to get a momentum of 21kg x m/s

Explanation:

Given parameters:

Final velocity of the bullet  = 720m/s

Distance covered  = 324m

Unknown:

Time for the bullet to strike a target = ?

Velocity in km/h

Solution:

To solve this problem, we use the kinematics equation shown below:

     S  =( [tex]\frac{v + u}{2}[/tex]) t

So;

        324  = [tex]\frac{720 + 0}{2}[/tex]  t

        324  = 360t

           t  = 0.9s

B. to convert this velocity to km/hr

       1000m  = 1km

       3600s  = 1hr

  720 x m x [tex]\frac{1}{s}[/tex]  x [tex]\frac{1km}{1000m}[/tex]  x [tex]\frac{3600s}{1hr}[/tex]    = 2592km/hr

Answer:

a = 30 [m/s²]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.

∑F = m*a

where:

m = mass = 2.5 [kg]

a = acceleration [m/s²]

F = force = 75 [N]

Now replacing:

[tex]75=2.5*a\\a=75/2.5\\a=30[m/s^{2} ][/tex]

Answer:

A sea star that has the ability to regenerate amputated limbs must first undergo a repair phase to heal the exposed wound. Once the wound is healed, the sea star can begin to generate new cells, which in turn, sparks new growth. Regeneration can take anywhere from several months to years. Reproduction: Sea stars are broadcast spawners. Males release sperm into the water and females release eggs. The fertilized eggs hatch into a larval form that lives as plankton, sometimes for months, before settling on the sea floor in its adult form..

Second Option

Explanation:

The "hard drive" or the second option is one of the main components of storing information on a computer. You already have a hard drive built into your computer, or laptop when you buy it, and you can buy additional hard drives in the form of plugins that can store even more data if your original hard drive becomes full of data.

Hope this helps.
