-4.3 light years what is the value of the 3??
Answer:
A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers
A capacitor has plates separated by
8.89 x 10-7 m. To create a
capacitance of 1.11 x 10-9 F, what
must the area of the plates be?
We know, formula of capacitance in parallel plate capacitor is given by :
[tex]C = \dfrac{\epsilon_o A}{d}[/tex]
Here, [tex]\epsilon_o = 8.85 \times 10^{-12} \ F.m^{-1}[/tex]
So,
[tex]A = \dfrac{Cd}{\epsilon_o}\\\\A = \dfrac{1.11 \times 10^{-9}\times 8.89 \times 10^{-7}}{8.85\times 10^{-12}}\\\\A = 1.11 \times 10^{-4}\ m^2 \ or \ 1.11 \ cm^2[/tex]
Hence, this is the required solution.
Answer:
7.09797297 • 10^-7
Explanation:
You just follow the formula:
C = εA/d
ε = 8.85 • 10^-12
A = 8.89 • 10^-7
D = 1.11• 10 ^-9
So:
C = (8.85 • 10^-12)(8.89• 10^-4)/1.11 • 10 ^-9 = 7.09797297 • 10^-7
Good Luck! :)

A. 100 years
B. 60 years
C. 10 years
D. 30 years
Ods are predicted to disappear from the atmosphere in 10 years. So, the correct option is C.
What is Atmosphere?A layer (or layers) of gases that surround a planet and are held together by the gravitation of the planetary body is known as an atmosphere. Whenever the gravity is strong as well as the atmospheric temperature is low, a planet preserves its atmosphere. The five separate layers of the atmosphere are a result of the temperature variations that occur with height.
The layer of gases that covers Earth and contains the air we breathe is known as an atmosphere. The gravitational pull of the planet's neighbor, Earth, keeps it close to the surface. To gauge air pressure, use a barometer. The three primary components of the atmosphere are nitrogen, oxygen, and argon.
Therefore, the correct option is C.

Una onda cuya frecuencia es igual a 550 Hz, se propaga en el aire. ¿ cual es su longitud de onda y su periodo?
Answer:
The wavelength of the wave is [tex]5.45\times 10^5\ m[/tex] and time period is 0.0018 s.
Explanation:
The given question is, "A wave whose frequency is equal to 550 Hz, propagates in the air. What is its wavelength and its period?"
Given that,
The frequency of a wave, f = 550 Hz
The time period of a wave,
[tex]T=\dfrac{1}{f}\\\\T=\dfrac{1}{550}\\\\T=0.0018\ s[/tex]
Wavelength,
[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{550}\\\\\lambda=5.45\times 10^5\ m[/tex]
So, wavelength of the wave is [tex]5.45\times 10^5\ m[/tex] and time period is 0.0018 s.
An artificial satellite is moving in a circular orbit of radius 24,600 km. Calculate its speed if it takes 12hours to revolve around the earth.
Answer:
the speed of the satellite is 12,880.53 km/h
Explanation:
Given;
radius of the circular orbit, r = 24,600 km
time taken to revolve around Earth, t = 12 hours
The circumference of the satellite is calculated as;
L = 2πr
L = 2π x 24,600 km
L = 49,200π km
L = 154,566.36 km
The speed of the satellite;
v = L/t
v = 154,566.36 / 12
v = 12,880.53 km/h
Therefore, the speed of the satellite is 12,880.53 km/h

Answer: 0.043mm/s
Explanation:
The drift speed of electron in this wire will ba calculated as:
= I/nqA
= I/nqπr²
= 3.7/[(1.1 × 1^29) × (1.6 × 10^19) × (3.14 × 0.00125²)
= 4.3 × 10^-5
= 0.043mm/s
The drift speed of the electron in this wire is 0.043mm/s.

Why does the pattern of colors repeat in a thin soap film? Please use 2 content related sentences. Need to refer to constructive interference and half wavelength intervals.
Answer:
A colorful interference pattern is observed when light is reflected from the top and bottom boundaries of a thin oil film. The different bands form as the film's thickness diminishes from a central runoff-point. ... So one set of light rays shine into a soap bubble, but two sets of rays come back out again.

A typical sound wave has a wavelength of 1 meter. The wavelength of green light is about 500 billionths of a meter. Which type of wave will tend to diffract more through a narrow gap that is about 1 centimeter wide? Explain.
Answer: Sound wave diffracts more.
Explanation: Width of gap d is smaller than wavelength λ of the gap.
You can estimate it from equation d sin α = n λ
The constant n is order of diffraction, n = 0,1,2,..
sin α = n λ / d is greater when λ/d is greater.
Sound wave will tend diffract more through a narrow gap that is about 1 centimeter wide.
What is Diffraction?Diffraction is the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wave like properties.
d sin α = n λ

A small balloon with a 1.36E-9 C charge is placed a distance of 0.4100 m from a 1.99E-7 C charge. Determine the electric field intensity at the location of the balloon. Round to the appropriate number of sig figs, and do not put your answer in scientific notation.
Answer:
The intensity of the electric field is
[tex]|E|=10654.37 \:N/C[/tex]
Explanation:
The electric field equation is given by:
[tex]|E|=k\frac{q}{d^{2}}[/tex]
Where:
k is the Coulomb constant q is the charge at 0.4100 m from the balloond is the distance from the charge to the balloonAs we need to find the electric field at the location of the balloon, we just need the charge equal to 1.99*10⁻⁷ C.
Then, let's use the equation written above.

Which of the following objects will exert the greatest gravitational force on a box, if the distance between them remains the same?
2 kg mass
4 kg mass
6 kg mass
8 kg mass
Given :
Some objects with different mass.
To Find :
Which of these object will exert the greatest gravitational force on a box, if the distance between them remains the same.
Solution :
We know, gravitation force between two object is given by :
[tex]F = \dfrac{Gm M}{d^2}[/tex]
Here m, G and d are constant.
From the above equation we can see that if every other thing remains constant the gravitations force remains constant if mass of other plant increase.
Therefore, object of mass 8 kg will exert the greatest gravitational force on a box.
Answer: 8 kg mass
