Answer:
Because you stand at a distance from the mirror at which your entire body shows.
Explanation:
Since the mirror is a plain mirror, the distance of the object from the mirror is also the distance of the image from the mirror. Also since the magnification is 1 for a plane mirror because the height of the image equals the height of the object. Since the magnification always equals 1, for you to be able to see your entire body, you must stand at a distance from the mirror such that your height equals the image height.
Answer: By keeping a distance away from the mirror.
Explanation:
If it's a plane mirror, it's possible to see your entire body by keeping distance away from the mirror. The distance of the object away from the mirror is equal to the distance of the image away from the mirror.

El dibujo muestra donde se encuentra un caracol en distintos instantes de tiempo.?Podemos afirmar que se trata de un movimiento acelerado?Razona tu respuesta
Answer:
if the acceleration is zero the displacements are equal in the same time interval, so we would see the points equally spaced in the diagram
if the acceleration is different from zero in these cases the intervals are different in the same time intervals
Explanation:
In a drawing of displacement as a function of time, we can know if in motion it is steely or not, the relationship that describes the motion is
x = v₀ t + ½ a t²
we see that we have two cases:
* if the acceleration is zero the displacements are equal in the same time interval, so we would see the points equally spaced in the diagram
* if the acceleration is different from zero in these cases the intervals are different in the same time intervals. In the case of positive acceleration the points are spaced and in the chaos negative acceleration the points are getting closer to each other
The acceleration of gravity means that for each second that passes, falling
objects move 9.8 meters.
A. True

What is the critical angle for glass when the refractive index is 1.45
Answer:43.6°
Explanation:
Refractive index=n=1.45
Critical angle=c
n=1/sinc
1.45=1/sinc
Cross multiply
1.45sinc=1
Divide both sides by 1.45
(1.45sinc)/1.45=1/1.45
sinc=0.6897
c=sin(inverse)(0.6897)
c=43.6°
Critical angle is 43.6°

A boat at anchor is rocked by waves whose crests are 28 m apart and whose speed is 7 m/s. How often do these waves reach the boat? State your answer in terms of frequency (Hz) and period T (seconds).
Answer:
0.25 Hz
4 s
Explanation:
Speed = wavelength × frequency
7 m/s = 28 m × f
f = 0.25 Hz
Frequency = 1 / period
0.25 Hz = 1 / T
T = 4 s
A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of the velocity and the acceleration of the brush as it falls? Pick the two answers. The velocity increases. The velocity decreases. The velocity remains a constant value. The acceleration increases. The acceleration decreases. The acceleration remains a constant value.
Answer:
Explanation:
As the paint brush is dropped from the top of a tall ladder it started free falling
i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.
We know acceleration due to gravity is the attraction experienced by the object due to earth attraction
Value of acceleration due to gravity is constant i.e. [tex]9.8\ m/s^2[/tex]
Therefore the correct choice is
velocity is increasing and acceleration is constant

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?
Answer:
white
Explanation:
This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.
Now, in diffraction fo a single slit we always have a central maximum (for all the colors)
This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white

En la etiqueta de un bote de fabada de 350 g, leemos que su aporte energético es de 1630 kj por cada 100 g de producto a) La cantidad de fabada que tiene que comer un hombre si su necesidad energética diaria es 2500 kj para sobrevivir b) El aporte calórico del bote de fabada en calorías
Answer:
(a) 153.37 g
(b) 5705 kJ
Explanation:
(a) To find the amount of bean needed by a man you first calculate the equivalence in beans to 2500kJ
[tex]2500kJ*\frac{100g}{1630kJ}=153.37\ g[/tex]
Thus, 153.37 g has the energy needed by a man that needs 200kJ per day.
(b) The amount of energy per pot of bean is given by:
[tex]E=350g*\frac{1630kJ}{100g}\\\\E=5705\ kJ[/tex]
Thus, the energy is 5705kJ

Question 19 options:
Product
Reactant
Limiting reactant
Spontaneous reactant
Answer: Limiting reactant
Explanation:
The limiting reactant is a reactant will get completely consumed up in the reaction. This reactant being in low concentration will lead to the formation of limited amount of product.
In the given situation, since the butter cakes are required to be 3 sticks for making 3 cakes but only 2 cakes are available thus the butter stick is the limiting reactant.
