Answer 1

[tex]\huge{ \mathcal{  \underline{ Answer} \:  \:  ✓ }}[/tex]

Given :

volume = 220 in³radius = 3 in

Solution :

[tex] \large\boxed{ \mathrm{volume = \pi {r}^{2}h }}[/tex]

[tex]220 = \dfrac{22}{7} \times 3 \times 3 \times h[/tex]

[tex] \dfrac{220 \times 7}{22 \times 3 \times 3} = h[/tex]

[tex] \dfrac{10 \times 7}{3 \times 3} = h[/tex]

[tex]h = \dfrac{70}{9} [/tex]

[tex] \boxed{h \: = 7.78 \: \: in}[/tex]

Answer 2

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!

Answers

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

Answer:

apples falling from trees people's feet touching the ground sky divers moving toward the ground  balls bending downward after being thrown​

Explanation:

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.

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

Answers

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.

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?

Answers

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

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?

Answers

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.

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.

differences between weightlessness in space and weightlessness in earth​

Answers

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.

Explanation:

Given

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
