Answer:
Consciousness is a psychological construct because it is believed to exist, but we are unable to physically measure it, so descriptions are 'constructed' to explain it. ... The more aware we are of our thoughts, feelings, perceptions and surroundings, the higher the level of consciousness.
What the effect positively charged objects and negatively charged objects have on each other
Answer:
often Positive and negative charges balance each other which gives an overall neutral charge. if they are unbalanced then it will result in static electricity.

how do various factors affect climent
Answer:
The factors affecting climate are latitude, altitude, land and water distribution, distance from the sea, distance from the sun, prevailing winds and ocean currents, surface covering the land, volcanism, solar constant sunspots, wind direction and nature of mountain chains, mountain barriers.
There are six major climatic controls. They are:
Latitude: As the earth is round, sunlight does not reach everywhere equally. The temperature decreases as we move from the equator to the poles.
Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases.
Pressure and wind system: The pressure and wind system of any area depend on the latitude and altitude of that place. Thus, it influences the temperature accordingly.
Distance from the sea: Coastal regions are cooler as compared to interior regions. As the distance from the sea increases, its influence decreases and the people experience extreme weather conditions.
Ocean currents: Cold ocean currents flowing over a region will decrease the temperature of that area whereas warm currents will increase the temperature.
Relief features: Relief features are the barriers that block currents from entering the country. High mountains act as barriers for cold or hot winds.
An astronaut is said to be weightless when he/she travels in a satellite. Does it mean that the earth does not attract him/her
First of all, what a weight is? weight is m × g.. and when a person is in space then the force of gravity isn't acting on him or her, so yeah it will not have weight, but remember gravity is a very very low, now if a body has more mass, more gravity will act on it right? just imagine the mass of a person and that of earth.. now yes, earth will do exert a force on the astronaut but is negiligable.

Answer in the proper number of significant numbers
23.4 x 14
Answer:
327.6 is the answer but there is 2 sig figs in 14 so change it to 330
so 330 is the final answer
hope this helps
have a good day :)
Explanation:
The multiplication product of 23.4 × 14 is 327.6. However, there is only two significant figures in 14. So we have to take the answer in 2 significant figure. Hence, the product can be written as 3.3 × 10².
What are significant figures ?Significant figures are number of digits which can be counted as certain values associated with some uncertainties as well. There are certain rules regrading the count of significant figures in a number.
The zeros after a non-decimal number cannot be taken as significant. For eg, in 4500, there are only two significant figures. The common rule for all the arithmetic operation is that, the significant figures in the product have to be equal to the number of significant figure in the number in the operation with least significant figures.
Here, the one with least significant figures is 14. It have two significant figures. Now, product of the two numbers is :
23.4 × 14 = 327.6
But the rounded product for correct significant figure is 3.3 × 10².

What occurs when light bends while passing from one medium to another?
Answer:So the answer is B
Explanation: When the light rays either bend or change their direction while passing from one medium to another it is called refraction of light. The refraction of light takes place when light travels from air into glass, from glass into air, from air into water or from water into air.

Un objeto de 200 gramos está amarrado del extremo de una cuerda y gira describiendo un círculo horizontal de 1.20 m de radio a razón de 3 rev/seg la tensión en la cuerda es?
Answer:
La tensión es 85.3 N.
Explanation:
Cuando el objeto gira en dirección horizontal, la sumatoria de fuerzas se puede calcular usando la segunda ley de Newton:
[tex] \Sigma F_{x} =ma_{c} [/tex]
[tex] T = ma_{c} [/tex]
Dado que el movimiento es horizontal, el peso (que está en el eje y) no contribuye en la sumatoria de fuerzas en el eje x. Por lo que la única fuerza actuando sobre el objeto en la dirección del movimiento es la tensión.
En donde:
m: es la masa del objeto = 200 g = 0.200 kg
[tex]a_{c}[/tex]: es la aceleración centrípeta
La aceleración centrípeta viene dada por:
[tex]a_{c} = \omega^{2} r[/tex]
En donde:
ω: es la velocidad angular del objeto = 3 rev/s
r: es el radio = 1.20 m
Entonces, la tensión es:
[tex]T = m\omega^{2} r = 0.200 kg(3\frac{rev}{s}*\frac{2\pi rad}{1 rev})^{2}*1.20 m = 85.3 N[/tex]
Por lo tanto, la tensión es 85.3 N.

HELP ASAP Miguel claims that as a ball falls, it loses potential energy. Izzy claims that as a ball falls, it
gains kinetic energy. Can both students be correct? Describe the evidence which would support
either student.
Answer and Explanation:
They are both correct.
This is because potential energy is when there is potential for the object to have energy, while kinetic energy is energy that is moving already.
So, as the ball falls, it loses its potential energy, or "still/Stalled" energy, and gains kinetic energy, or moving energy.

Determine la inercia rotacional de una varilla de 4 m de largo y 2 Kg de mesa si su eje de rotación esta situado a la mitad de la varilla.
Answer:
I = 2.667 kg m²
Explanation:
The moment of inertia of a body can be calculated by the expression
I = ∫ L² dm
For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is
I = [tex]\frac{1}{12}[/tex] m L²
let's calculate
I = [tex]\frac{1}{12}[/tex] 2 4²
I = 2.667 kg m²

How many electrons are contained in 1.0 C of charge? What is the mass of the electron in 1.0C of charge?
There are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge. The mass of the electron in 1.0 C of charge remains the same as the mass of an electron, which is approximately 9.109 x 10⁻³¹ kg.
We may utilise the elementary charge, which represents the charge of a single electron, to calculate how many electrons are present in 1.0 C of charge. It is estimated that the elementary charge is 1.602 x 10-19 C.
Number of electrons = Charge ÷ Elementary charge
Number of electrons = 1.0 C ÷ (1.602 x 10⁻¹⁹ C)
Calculating the division:
Number of electrons ≈ 6.24 x 10¹⁸ electrons
Therefore, there are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge.
It is crucial to remember that the electron's mass is unaffected by the charge when considering the electron's mass in 1.0 C of charge. Regardless of the charge it carries, an electron has a mass of about 9.109 x 10⁻³¹ kg.
Thus, the mass of one electron, which is roughly 9.109 x 10⁻³¹ kg, remains constant in 1.0 C of charge.

Explanation:
I literally just did this question lol I hope I helped
In an ecosystem having a park, from the given data there are 71 male,93 female, 103 adults and 61 baby goats in the park.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which of the following correctly describes how particular type of mirror reflects light? Convex mirrors reflect light to a central point (converging). Concave mirrors reflect light to a central point (converging). Concave mirrors reflect light so the light spreads out (diverging).
Answer:
Concave mirrors reflect light to a central point (converging)
Suppose the source is to the left of the mirror in question.
Parallel rays into the mirror are always reflected towards the focal point.
In the case of a concave mirror the real parallel rays pass thru the focal point.
If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.
