Chauncy is driving down the hill that descends at an angle a 4.5° below horizontal. After driving 4.60 kilometers along the road, how much elevation has chauncy lost?

Answer:

36 km / hr

Explanation:

velocity final = velocity initial + accel * time

                             20 m/s     + (-2)*5                ( 20 m/s = 72 km/hr)

                                10 m/s     ( or 36 km/hr)

Answer:

Sound waves can reflect off surfaces. We hear sound reflections as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes.

Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.

Explanation:

With this information, you'd be able to come up with your answer,

Hope this helps!

yea, by sound enegy example if uh speak a your sound knock on the object and react to your ears

Answer: 10 m/2^2

F=ma

Explanation:

Force = 1000N

1 N is 1 (kg*m/s^2)

Mass = 100kg

F=ma

a = F/m

a = (1000kg*m/s^20/(100kg)

a = 10 m/s^2

Considering the definitipn of current, voltage, power, and Ohm's law,

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.

The conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.

This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.

The resistance that is measured in ohms.

Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically, Watt's law is expressed:

[tex]I=\frac{V}{R}[/tex]

So if you want to find resistance, the expression for its calculation is:

[tex]R=\frac{V}{I}[/tex]

In this case, you know:

Replacing:

[tex]R=\frac{5.26 V}{0.41 A}[/tex]

Solving:

R= 12.8 ohms

Habiba is right. The resistance is 12.8 ohms.

Answer:  In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.

Explanation:

Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.

The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

Inside a laser apparatus, the stimulation and relaxation of electrons in atoms cause many photons with the same wavelength to be continuously emitted.

From the questions given, the main objective is to fill in the gaps and add important information where necessary. The missing information is highlighted in bold and underlined.

Therefore, we can conclude that we've fully understood the concept of emission of photons and wavelength in a laser apparatus.
