Answers

Answer 1

The kinetic energy of the air travelling at 12m/s, which passes through

the circular area in 1 second is 5.4 x 10⁵ J.

What is kinetic energy?

The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as

K.E = 1/2 mv²

Given the wind is blowing directly towards the wind turbine at a speed of 12 m/s. At this wind speed, 7500 kg of air passes every second through the circular area swept out by the blades.

Substitute the values, we have

K.E = 1/2 x 7500 x (12)²

K.E = 5.4 x 10⁵ J

Hence, the kinetic energy of the air travelling at 12m/s, which passes through the circular area is  5.4 x 10⁵  J.

the speed of all electromagnetic waves in emoty space is 3.0x10^8 m/s .calculate the wavelength for radio waves with frequency 100.0 mhz

Answers

Taking into account the definition of wavelength, frecuency and propagation speed, the wavelength for radio waves with a frequency of 100 MHz is 3 m.

Definition of wavelength, frecuency and propagation speed

First of all, wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

On the other side, frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

Finally, the propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f×λ

All electromagnetic waves propagate in a vacuum at a constant speed of 3×10⁸ m/s, the speed of light.

Wavelength for radio waves

In this case, you know:

v= 3×10⁸ m/sf= 100 MHz= 100,000,000 Hz (being 1 MHz = 1,000,000 Hz)λ= ?

Replacing in the definition of propagation speed:

3×10⁸ m/s = 100,000,000 Hz× λ

Solving:

λ= 3×10⁸ m/s ÷ 100,000,000 Hz

λ= 3 m

In summary, the wavelength for radio waves with a frequency of 100 MHz is 3 m.

A conducting sphere with radius R carries total charge Q. What is the magnitude of the electric field at distances R/2 and 2R from the center of the sphere

Answers

Hello!

Distance of R/2:

Since a conducting sphere is referenced in this situation, all of its charge will be distributed along its SURFACE. Therefore, there is NO enclosed at a distance of R/2 from the center.

Using Gauss's Law:
[tex]\oint E \cdot dA = E\cdot A = \frac{Q_{encl}}{\epsilon_0}[/tex]

E = Electric field strength (N/C)
A = Area of Gaussian surface (m²)

Q = Enclosed charge (C)
ε₀ = Permittivity of free space C²/Nm²)

If the enclosed charge is 0, then:
[tex]E \cdot A = \frac{0}{\epsilon_0}\\\\\boxed{E = 0 \frac{N}{C}}[/tex]

Distance of '2R':

We can once again use Gauss's Law to solve. This time, however, a surface of radius '2R' encloses ALL of the charge of the sphere.

[tex]E \cdot A = \frac{Q_{encl}}{\epsilon_0}[/tex]

'A' is equivalent to the surface area of a sphere of radius '2R', or:
[tex]A = 4\pi (2R)^2\\\\A = 4\pi (4R^2)\\\\A = 16\pi R^2[/tex]

Substituting this expression back into Gauss's Law:
[tex]E \cdot 16\pi R^2 = \frac{Q}{\epsilon_0}\\\\E = \frac{Q}{16\pi R^2\epsilon_0}[/tex]

To simplify:
[tex]E = \frac{1}{4\pi \epsilon_0 } * \frac{Q}{4R^2}\\[/tex]

OR using k = 1/4πε₀:
[tex]\boxed{E = \frac{kQ}{4R^2}}[/tex]

In series , the resistances add together 100 + 3900 + 1000 = 5000 ohms total

V = IR

I = V / R      so the total current will be   200 v / 5000 ohms = .04 amps

                   this is the current through all of the resistors

      so for the   1000 ohm resistor     V = IR     .04 (1000) = 40 V

An object whose mass is 0.092 kg is initially at rest and then attains a speed of 75.0 m/s in 0.028 s. What average net force acted on the object during this time interval?

Answers

Answer:

F = 246.4 N

Explanation:

Concepts:Newton's Laws Of Motion

First Law: (Law of Inertia)

Inertia refers to the tendency of an object to resist any change in its state of motion. Inertia is a measure of the objects mass.

Second Law:

refers to an object's motion when a net force does not equal zero. Acceleration is directly proportional to the net force and inversely proportional to the object's mass.

Third Law: (Action - Reaction)

Whenever one object exerts a force on a second object, the second objects exert an equal but opposite force on the first.

Weight:

Force of gravity is the weight of an object and is measured in Newtons.

Friction:

Frictional forces always oppose motion. The frictional forces ([tex]F_f[/tex]) is proportional to the coefficient of friction (Ц) and to the normal force [tex](F_n) F_f=uF_n[/tex].The normal force is a contact force which acts perpendicular to the common surface of contact.

Now onto the steps:
----------------------------------

F = mΔV ÷ t

F = 0.093 x 75 ÷ 0.028

F = 246.4 N

Therefore, the average net force acted on the object during this time interval is 246.6 Newtons.

What is speed of sound in air?

Sound is an example of a mechanical wave and require a material medium for it's transmission.

The speed of sound in air has been determined to be about 343 m/s at 20 °C.

The average wave speed can be calculated using the formula:

Average wave speed = (initial speed + final speed)/2

The formula relating speed of a wave, frequency, and wavelength is given below:

Speed = wavelength × frequency.

It is important to note that in this question, no data table or video was provided.

Therefore, the wave speed be calculated by taking the mean of speed values obtained in the experiment as shown in the video.

Also, the mathematically derived speed of sound is 343 m/s at 20 °C.
