Answer:
15,00kg
Explanation:
here's your solution
=> force = 45,000N
=> acceleration = 30m/s^2
=> mass = ?
=> Mass = force/acceleration
=> mass = 45,000/30
=> mass = 15,00kg

What would a series circuit be used for?
A. to power a battery
B. to light a lamp
C. as a voltage divider
D. convert chemical energy to thermal energy
Answer:
C
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

Objects A and B are brought close to each other. Object A will soon become positively charged. Identify the charge that must transfer for this
situation to occur.
+
A
B
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.
What is charging by conduction?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.

Give reasons for the following:
a. We should not see the solar eclipse directly through our unaided eyes.
b. Dark patches are seen on the ground when sunlight passes through dense tree.
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.

An image is a copy of an object formed by ____
light.
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.

If the number of oscillators with energy is 100 , 000, calculate the number of oscillators in the black body with energy 1 . (Accoding to Max. Planck, the number of oscillators with energy ℎ at a particular frequency is given by = = − ( ⁄ ) = − ( ⁄ ) (10 Marks) (b) Calculate the peak wavelength of a black body's radiation if the black body is at a temperature of 20 , 000 . (5 Marks)
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

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.

A model rocket accelerates at 15.3 m/s2 with a force of 44 N.
Calculate the mass of the rocket. Round your answer to the nearest tenth of a kg.
The mass of the rocket is kg.
Fill in the blank above. Also what is the formula to find the mass. Include that in the answer pls.
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

30. CHALLENGE A disk with a moment of inertia
of 0.26 kg ma is attached to a smaller disk
mounted on the same axle. The smaller disk has
a diameter of 0.180 m and a mass of 2.5 kg.
A strap is wrapped around the smaller disk,
as shown in Figure 14. Find the force needed
to give this system an angular acceleration of
2.57 rad/s?
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

Un texto de opinión sobre la situación actual del rol de la mujer, el trabajo y las situaciones de violencia en el contexto de Pandemia. Cambió la situación de las mujeres?
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.

There is a bell at the top of a tower that is 95 m high. The mass of the bell is 21 kg. What is the potential energy of the bell?
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
How much work in joules is required to lift a 23 kg box up from the ground to your waist that is 1.0 meters high, carry it 6 meters horizontallyy across the room and place it on a shelf that is 5.7 meters off the ground? Do not type units. Round your answer to te tnths place
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)
