Answer:
0.078 inches
Explanation:
The volume of a cylinder is [tex]V=\pi r^{2} h[/tex]. [tex]r[/tex] is the radius of the cylinder, [tex]h[/tex] is the height of the cylinder, and [tex]V[/tex] is the total volume.We can divide both sides by [tex]9\pi[/tex] to isolate the height. We now have [tex]\frac{220}{9\pi }=h[/tex].We can plug in [tex]220[/tex] for the value of [tex]V[/tex], and insert 3 as [tex]r[/tex]. Now, we have [tex]220 = \pi (3^2)(h)[/tex].We can simplify the right side by finding the value of [tex]3^2[/tex], which is [tex]3*3[/tex], or [tex]9[/tex]. We now have [tex]220 = 9\pi h[/tex].Divide both sides by [tex]9\pi[/tex] so we can isolate the height! We now have [tex]\frac{220}{9\pi }=h[/tex].It would be best to use a calculator at this point. Plug the above equation into a calculator; otherwise, replace [tex]\pi[/tex] with [tex]3.14[/tex] and simplify the fraction. You should get about [tex]07.7809...[/tex] which we can round to the nearest hundredths (since this is Geometry, I am assuming you know how to round).Our final answer is [tex]07.78[/tex] inches.Hopefully this was of use!

How are wave properties and energy related?
EXPLAIN
Answer:
The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

Se dea caer una pelota de basquetbol desde una altura de 90 metros.Calcular: El tiempo en que demorara en caer y a velcidad con la que llega al suelo
Answer:
1. t = 4.24 s
2. [tex]v_{f} = 42.43 m/s [/tex]
Explanation:
Podemos encontrar el tiempo de caída con la siguiente ecuación:
[tex] v_{f} = v_{0} + gt [/tex] (1)
En donde:
[tex] v_{f}[/tex]: es la velocidad final de la pelota
[tex] v_{0}[/tex]: es la velocidad inicial = 0 (se deja caer)
g: es la aceleración debida a la gravedad = 10 m/s²
Debemos hallar primero la velocidad final. Podemos usar la ecuación:
[tex] v_{f}^{2} = v_{0}^{2} + 2gh [/tex] (2)
En donde:
h: es la altura = 90 m
[tex] v_{f} = \sqrt{2gh} = \sqrt{2*10 m/s^{2}*90 m} = 42.43 m/s [/tex]
Entonces, la velocidad con la que la pelota llega al suelo es 42.43 m/s.
Ahora podemos encontar el tiempo que tarda en caer la pelota resolviendo la ecuación (1) para "t":
[tex] t = \frac{v_{f}}{g} = \frac{42.43 m/s}{10 m/s^{2}} = 4.24 s [/tex]
Por lo tanto, la pelota tarda 4.24 segundos en caer.

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.

When a certain metal is illuminated with light of frequency 2.9 ✕ 1015 Hz, a stopping potential of 7.0 V is required to stop the most energetic ejected electrons. What is the work function of this metal?
Answer:
4.96 eV
Explanation:
Recall the Einstein photoeletric equation;
KE = E - Wo
Where;
KE = kinetic energy of the ejected photoelectron
E= energy of the incident photon
Wo = Work function
But
KE = eV= 1.6 * 10^-19 C * 7 V /1.6 * 10^-19 C = 7 eV
E = hf/e = 6.6 * 10^-34 * 2.9 ✕ 10^15 Hz/1.6 * 10^-19
E = 11.96 eV
Hence;
Wo = E - KE
Wo = 11.96 eV - 7eV
Wo = 4.96 eV
on which factor does gravitation between any two bodies depend?
Answer:
Gravitational force between two bodies depends on:
1. Masses of the two bodies. The greater an object's mass, the greater its gravitational force.
2. Distance of separation between them. The smaller the distance greater is the gravitational force.
1. This force keeps an object floating _______________________ 2. When the force of gravity is stronger then the buoyant force an object will ___________ 3. When the buoyant force is the same as the force of gravity an object will ____________ 4. When the buoyant force is greater than the force of gravity an object will ____________ 5. Why does an aircraft carrier float
Answer:
1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force
Explanation:
A body in a fluid is subjected to two forces, its weight and the thrust
sun F = B - W
the em
bid is always vertical and contrary to weight, let's analyze and complete the different situations presented
1) Buoyant force
2) sinks B <W
3) equilibrium B = W
4) fleet B> W
5) by the sum of two forces:
* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.
* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called LIFT force

Does a battery produce electric currents?
Answer:
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

Brad is swimming in the ocean on a hot sunny day. He finds the water to be much colder than the sand on the beach, even though the sun is warning them both. Identify the reasons for brads observation
Answer:
When Brad was swimming in the ocean and then he observed that the sand was more hotter than the water of the ocean. The water is colder than the sand because the water needs more energy as compared to sand to change its temperature. This is because the water has a higher specific heat than sand.

Explanation:
A positive charge of 8.0 × 10-4 C is in an electric field that exerts a force of 3.5 × 10-4 N on it. What is the strength of the electric field?
Answer:
E = 0.437 N/C
Explanation:
Given that,
Charge, [tex]q=8\times 10^{-4}\ C[/tex]
Electric force, [tex]F=3.5\times 10^{-4}\ N[/tex]
Let the strength of the electric field is E. We know that, the electric force is given by :
F = qE
Where
E is the electric field strength
[tex]E=\dfrac{F}{q}\\\\E=\dfrac{3.5\times 10^{-4}}{8\times 10^{-4}}\\E=0.437\ N/C[/tex]
So, the strength of the electric field is equal to 0.437 N/C.
There is a fixed voltage across a resistor, and you measure a current of c1 A. If you replace the resistor with one that has twice the resistance value, how much current will you measure? a) 0.2 A b) 0.5 A c) 0.8 A d) 1.1 A
Answer:
Option B
Explanation:
Given
The current flowing through the circuit = 1 Ampere
As we know
I is inversely proportional to resistance.
I α 1/r
or I = k/r
If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be
I = 1/2 of 1 ampere
I = 0.5 Ampere
Hence, option B is correct

differences between weightlessness in space and weightlessness in earth
Answer:
it depends on a person's own weight
Answer:
The gravity is roughly the same. The inverse square law applies to gravity and that means that being 60 miles above Earth is about the same as being on Earth. The thing is, they are going really fast in an orbit and thus falling around the Earth. The weightlessness comes from a sort of cancellation of gravity pulling them down and their going perpendicular to that force. The forces are cancelling and making them relatively “weightless”. It’s not really weightlessness but just an equilibrium reached between the two accelerations of gravity and their motion against the pull of the Earth.

Answer:
apples falling from trees people's feet touching the ground sky divers moving toward the ground balls bending downward after being thrownExplanation:
When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.
This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.
