Answer:
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
In many ways, sound waves are similar to light waves. They both originate from a definite source and can be distributed or scattered using various means. Unlike light, sound waves can only travel through a medium, such as air, glass, or metal. This means there’s no sound in space!
Explanation:
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

Explanation:
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

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.

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.

All solid objects will deform when enough force is applied.
O True
False
Answer:
Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to plasticity, in which the object fails to do so and instead remains in its deformed state.
Explanation:
Answer:
It is false
Explanation:
because when it like a rolling ball it can deform no matter what unlesss you throw it at the ground really hard then it breaks but a soft or sometimes metal yeah it can deform but not all things solid deform.

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.

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.

Some liquid is poured into a burette so that it reads 14cm³.50 drops were run each of volume 0.1cm³ What is the volume of the 50 drops. (4marks)
Answer:
V = 5 cm³
Explanation:
In this exercise the volume (Vo = 0.1 cm³) of each drop is indicated, requesting the volume of 50 drops
V = V₀ #_drops
V = 0.1 50
V = 5 cm³
Answer:
[tex]V_{50}=5cm^3[/tex]
Explanation:
From the question we are told that:
Volume of liquid in burette [tex]V_b=14cm^3[/tex]
Volume of drop of liquid [tex]V_d=0.1cm^3[/tex]
Number of drops [tex]n=50[/tex]
Generally the equation for volume of 50 drops V_{50} is mathematically given by
