The earth makes one complete revolution around the sun in 365.24 days. Assuming that the orbit of the earth is circular and has

Anni [7]

Answer:

The magnitudes of the speed and acceleration of the Earth are approximately 66,661.217 miles per hour and 47.782 miles per square hour, respectively.

Explanation:

Given that the Earth has a circular orbit and make a revolution at constant speed around the Sun. Then, the kinematic formulas for the speed and acceleration of the planet are, respectively:

Speed

$v = \frac{2\pi\cdot R}{T}$ (1)

Acceleration

$a = \frac{4\pi^{2}\cdot R}{T^{2}}$ (2)

Where:

$v$ - Speed of the planet, measured in miles per hour.

$a$ - Acceleration of the planet, measured in miles per square hour.

$R$ - Radius of the orbit, measured in miles.

$T$ - Period of rotation, measured in hours.

If we know that $R = 93,000,000\,mi$ and $T = 8,765.76\,h$ , then the magnitudes of the speed and acceleration of the planet is:

$v = \frac{2\pi\cdot (93,000,000\,mi)}{8,765.76\,h}$

$v \approx 66,661.217\,\frac{mi}{h}$

$a = \frac{4\pi^{2}\cdot (93,000,000\,mi)}{(8,765.76\,h)^{2}}$

$a\approx 47.782\,\frac{mi}{h^{2}}$

The magnitudes of the speed and acceleration of the Earth are approximately 66,661.217 miles per hour and 47.782 miles per square hour, respectively.

A fighter plane is flying overhead at mach 1.20. What angle does the wave front of the shock wave produced make relative to the

Sever21 [200]

Answer: 56.44°

Explanation:

Given:

Let u represent the current speed of the plane, 1.2 Mach

Converting to SI Units (m/s):

= (1.2 mach)(340 ms^-1 / 1 Mach)

u = 408 m/s

Speed of sound in air, v = 340 m/s

Find:

Angle the wave front of the shock wave relative to the plane's direction of motion, θ

We have, sinθ = speed of sound / speed of object

sinθ = v / u

θ = sin^-1 (v / u)

= sin^-1 (340 / 408)

θ = 56.44°

Even in the most advanced circuits, we cannot oscillate electrons back and forth at that rate through wires. But we can oscillat

den301095 [7]

Answer:

the oscillations of the electrons must be in the 10⁸ Hz = 100 MHz range

Explanation:

The speed of a wave of radio, television, light, heat, all are manifestations of electromagnetic waves that are oscillations of electric and magnetic fields that support each other, the speed of all these waves is the same and the vacuum is equal to c = 3 108 m / s

All waves have a relationship between the speed of the wave, its frequency and wavelength

c = λ f

f = c /λ

for this case lam = 1 m

f = 3 10⁸/1

f = 3 10⁸ Hz

the oscillations of the electrons must be in the MHz range

It should be clarified that the speed of light in air is a little lower

n = c / v

v = c / n

the refractive index of vacuum is n = 1 and the refractive index of air is n = 1.000002
