Answer:
Radiation
Explanation:
The sun heat the earth by the process called radiation.
Radiation is form of heat transfer method just like convection and conduction. Radiation heat transfer does not require medium to propagate, unlike its other two counterparts. There is no medium between earth and sun.
The radiation heat travels through space in form of waves. Like the electromagnetic wave with a specific speed and energy.

12. You and a friend are playing a game of basketball. Explain why the
basketball appears orange, be sure to use terms reflected and absorbed
in your answer. [4]
Help me plssss I’m giving out brainlest and 10 points
Answer:
If the basket ball appears orange then it can be said that it reflects orange light
Explanation:
The color of the object reflected by an object is the color which is viewed by a viewer. Hence, if the basket ball reflects the orange color light , then the ball will appear orange in color to the viewer.
The light absorbed by the object has no role in deciding the color of the object visible to a viewer.
hence, if the basket ball appears orange then it can be said that it reflects orange light.
Aniyah is driving down 7th street. She drives 150 meters in 25
seconds. Assuming she does not speed up or slow down, what
is her speed in meters per second?
Answer:
6m/s
Explanation:
formula used; S= d/t
the "7th Street"doesn't matter it's just apart of the scenario. The only thing that matters is the distance and time which we have. the speed in seconds is 6. I had the same question on my phsyics quiz lol.

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
Width of gap d is smaller than wavelength λ of the gap.
The constant n is order of diffraction, n = 0,1,2,..
sin α = n λ / d
Diffraction is greater when λ/d is greater.

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.
how long is it estimated that it will take for ods to leave the atmosphere?
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.

A copper wire has a circular cross section with a raduis of 1.25mm. If the wire carries a current of 3.70A, find the drift speed of electron in this wire.
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.
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
