How far can you get away from your little brother with the squirt gun filled with paint if you can travel at 3 m/s and you have 0.25 min before he sees you?
Answers
Answer:
s = 45 m
Explanation:
The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:
[tex]s = vt[/tex]
where,
s = distance traveled away from the brother = ?
v = constant speed = 3 m/s
t = time taken = (0.25 min)(60 s/1 min) = 15 s
Therefore, using these values in the formula we get:
[tex]s = (3\ m/s)(15\ s)\\[/tex]
s = 45 m
Miranda performed an experiment to determine what makes an object sink
or float in water. She experimented with 10 different items and recorded
the results. Which of the following is correct?
The object's shape is the only determining factor.
The size of the object determines if it will sink or float
The mass and volume of an object determine if it will sink or float
Light-colored objects tend to float more easily than darker-colored object
Answers
Answer:
I guess the answer is
-The mass and volume of an object determine if it will sink or float
Explanation:
An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
density=mass/volume

When an object slides,there is less friction than when it rolls
Answers
Answer:
False
Explanation:
Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other. Rolling friction is much less than sliding friction for same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them.

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.
Answers
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

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.
Answers
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.

Write 3 major differences between a shadow and a image?
Answers
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.

(5 Marks)
Answers
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

An electron acquires 7.45 x 10 ^-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates, and which plate is at the higher potential?
Answers
Answer: Kinetic energy of electron = 7.45 x 10^-16 J We know that Potential difference = Work done per unit charge = Kinetic energy of electron / ( 1.6 x 10^-19 ) = (7.45 x 10^-16) / ( 1.6 x 10^-19) = 4656.25 V
Explanation:
The potential difference between the plates is [tex]4650.43V[/tex]
The Potential difference is also defined as the work done per unit charge.
Work done = kinetic energy = [tex]7.45*10^{-16}J[/tex]
Charge on one electron = [tex]1.602*10^{-19}C[/tex]
Potential difference,
[tex]V=\frac{7.45*10^{-16}}{1.602*10^{-19} }=4650.43Volt[/tex]
Hence, the potential difference between the plates is [tex]4650.43V[/tex]

Radio telescopes beam radio waves into space. To calculate the speed of the radio waves in space, which information, if any, is necessary?
Answers
Answer:
No more information is needed
Explanation:
Radio waves are electromagnetic energy, lower frequency forms of this type of energy that includes light and cosmic rays on the high frequency end that we are able to detect. So in free space (vacuum), radio waves travel at their fastest velocity, the “speed of light”. The reason for the quotation marks is because when light or radio waves are propagating through matter, we observe them traveling more slowly.
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?
Answers
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.
