Answer:
ice is a poor conductor of heat and less dense than water. During winter, ice floats and insulates the water under it. Below the frozen layer, the water remains in its liquid state and does not freeze. Also, oxygen is trapped beneath the layer of ice. This makes it possible for aquatic animals to survive during winter.

When an object slides,there is less friction than when it rolls
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.
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.

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
Radio telescopes beam radio waves into space. To calculate the speed of the radio waves in space, which information, if any, is necessary?
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.
What does the force of gravity do for us?
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.
Explanation:
Write 3 major differences between a shadow and a image?
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.
Which of the following electrical components is a temporary electrical energy storage device?
- Capacitor
- Transistor
- Resistor
- Fuse
Answer:
A capacitor
Explanation:
Because it can store electric energy when disconnected from its charging circuit. Commonly used in electronic devices to maintain power supply while batteries change.

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

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?
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]
