Answer:

19,551 J!

Explanation:

The formula is PE = ham (h=height, a= acceleration or 9.8, m= mass)

PE = (95)(9.8)(21)

PE = 19,551 Joules

Answer:

According to Newton's Second Law of Motion :    

Where,

F = Force Applied

m = Mass of the object

a = Acceleration

Now, we will use this law to solve this question.

Given :

Acceleration or a = 15.3 m/s²

Force = 44 N

Mass = ?

Substitute, the given values in the formula.

F = ma

⇒ m = F/a

   m = 44/15.3

m = 2.9 kg

Answer:

Explanation:

For A to become positively charged, a + charge must transfer from B to A.

The charge that must transfer for object A to become positively charged is the negative charge in object A.

Charging by conduction occurs when a charged object causes the flow of electron when it comes in contact with an uncharged object.

An object can either be negatively or positively charged. An object is said to be positively charged when it contains more protons than electron.

Therefore, for object A to be positively charged, the charge that must transfer for object A to become positively charged is the negative charge.

Answer:

We know that the electronic charge is 1.6 E-19 coulombs

Therefore 1 coulomb of charge contains 1.6  E19 electrons

A charge of 16.7 E6 coulombs therefore contains

N = 16.7 E6 * 1.6 * E-19 = 2.67 E-12 electrons

Also, the charge on the proton equals that on the electron

The answer is: Reflected

Explanation:

An image is a copy of an object that is formed by reflected (or refracted) light. Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

you are going 1 mile per hour depending on how fast

Explanation:

Answer: An equation is missing in your question below is the missing equation

a) ≈ 8396

b) 150 nm/k

Explanation:

A) Determine the number of Oscillators in the black body

number of oscillators = 8395

attached below is the detailed solution

b) determine the peak wavelength of the black body

Black body temperature = 20,000 K

applying Wien's law / formula

λmax = b / T  ------ ( 1 )

T = 20,000 K

b = 3 * 10^6 nm

∴  λmax = 150 nm/k

Explanation:

Los derechos de las mujeres fueron conquistados a través de importantes luchas llevadas a cabo por mujeres, como el movimiento feminista que tuvo lugar a fines del siglo XIX, cuyo principal reclamo fue el derecho al voto de las mujeres.

Con el tiempo, las mujeres ganaron más derechos y una mayor participación en el mercado laboral y en puestos importantes de la sociedad. Pero aún queda mucho por cambiar, ya que las estadísticas aún muestran que hay pocas mujeres en posiciones de poder en relación a los hombres, y el salario de una mujer que ocupa el mismo puesto que un hombre es siempre menor.

Dado que la sociedad se concibió a través de parámetros sexistas, lo que continúa en la actualidad, es claro que en la pandemia específicamente que generó crisis económicas en todo el mundo, se vio a una gran cantidad de mujeres perder sus empleos, además del expresivo número de casos de violencia doméstica que se agravaron en el período de aislamiento social.

Así que estos hechos solo demuestran que la lucha por la igualdad de género y los derechos de las mujeres aún están en sus inicios, a pesar de muchos logros que las mujeres aún deben luchar por lo básico, que es el apoyo social y político además de una legislación más estricta que castiga con más rigor a las agresoras. Las mujeres deben estar protegidas por la ley y las instituciones y los medios de comunicación deben abordar más el tema y promover el feminismo como una lucha por la igualdad.

Answer:

Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).

Explanation:

Answer:

is there more context to go with this question? Like a photo?

I will give it my best shot anyhoo

Explanation:

Polyatomic ions: they are covalently bonded groups of atoms and having a positive or negative charge caused by the formation of an ionic bond with another ion.

And if your question is anything like the one I had a few days ago on a test, your answer would be something like "Both hydroxide cation (OH -) and phostphate cation (PO 4 3 -) are polyatomic ions)

Answer:

2682

Explanation:

Work done is given by :

Work = Force x distance

         =  mg x d

So, work done in lifting the box of 23 kg up to my waist of 1 m high is :

W = mg x d

   = 23 x 9.18 x 1

   = 211.14

Now work done carrying the box horizontally 6 meters across the room is

W = mg x d

   = 23 x 9.18 x 6

   = 1266.84

Work done in placing the box on the shelf that is 5.7 m above the ground is

W = mg x d

   = 23 x 9.18 x 5.7

   = 1203.49

So the total work done is = 211.14 + 1266.84 + 1203.49

                                          = 2681.47

                                          = 2682 (rounding off)

Explanation:

a series circuit would be an odd choice to power a battery or light a lamp when a direct would be much more efficient, and it's not converting types of energy, so C is the best possible answer

Answer:

Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.

That be your answer.

Answer:

7.42 N

Explanation:

We know that:

τ = Iα = rF

Variables:

I = 0.26 kgm^2

α = 2.57 rad/s^2

r = 0.18m/2 = 0.09m

Solve:

τ = Iα = rF

τ = (0.26kgm^2) (2.57rad/s^2) = (0.09m) * F

F = 7.42 N

Static Friction - acts on objects when they are resting on a surface

Sliding Friction -  friction that acts on objects when they are sliding over a surface

Rolling Friction - friction that acts on objects when they are rolling over a surface

Fluid Friction - friction that acts on objects that are moving through a fluid

Explanation:

Examples of static include papers on a tabletop, towel hanging on a rack, bookmark in a book , car parked on a hill.

Example of sliding include sledding, pushing an object across a surface, rubbing one's hands together, a car sliding on ice.

Explanation:

c I think this is the answer

Answer:

The correct answer is "625,000 J".

Explanation:

The given values are:

Mass,

m = 2,000 kg

Speed,

v = 25 m/sec

As we know,

⇒  [tex]Kinetic \ energy=\frac{1}{2} (mass \times speed^2)[/tex]

Or,

⇒  [tex]K.E=\frac{1}{2}(mv^2)[/tex]

On substituting the values, we get

⇒          [tex]=\frac{1}{2}(2,000\times 25^2)[/tex]

⇒          [tex]=1000\times 625[/tex]

⇒          [tex]=625,000 \ J[/tex]              

Answer:

a)The reason why people are advised not to watch the Solar Eclipse with naked eyes is that when the Moon in direcly between the Earth and the Sun, the rays from the Sun that reach the Earth are more powerful and can permanently damage our retina (most important part of the eye).

Explanation:

b ) The leaves of the trees obstruct (stop) the rays coming from the sun as there is no sun the soil to will be marshy. in some places where the leaves are not thick the sunlight penetrates to the ground... therefore one mostly sees dark patches on the ground in dense forests.

Answer:

Explanation:

Image Shadow

2. We are able to see images when light refraction enters our eyes.

In the case of shadow no light enters our eyes.

3. Image contains colour, structure etc. of the object.

Shadow does not give any information about the object as it is colourless

Answer:

We know that an image is a picture of an object while shadow is formed an object comes in between the surface and light. ... The formation of image takes place when the light rays are reflected by an object. The formation of shadow takes place when the light falls on an opaque object.

Answer:

Explanation:

False

Answer:

   f = 4.67 Hz

Explanation:

We can approximate the wave as a traveling wave, therefore the speed of the wave is constant

          v = d / t

the total distance remember, in going to the wall and back is

          d = 2 11.2 = 22.4 me

we substitute

          v = 22.4 / 4.0

          v = 5.6 m / s

now we can use the relationship between the speed of the wave, its wavelength and u frequency

          v =λ f

          f = v /λ

          f = 5.6 / 1.2

          f = 4.67 Hz

Answer:

As per the law of conservation of angular momentum, the angular velocity will be higher for the body with a lower moment of inertia and vice versa.

Explanation:

Angular momentum L of a body is given by:

[tex]L=I\times \omega[/tex]

Now when the same angular momentum is transferred to two different bodies with different moment of inertia, the body with a higher moment of inertia will have lower angular velocity and vice versa.
