What is Digital data?
Digital data is information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits, in information theory and information systems. s. Binary data is the most common type of digital data in modern information systems. It is represented by a string of binary digits (bits), each of which can have one of two values, 0 or 1.
In contrast to digital data, analog data is represented by a value from a continuous range of real numbers.

Option C is correct. It has a high frequency. Wavelength is inversly proportional to the frequency. For short-wavelength, the frequency will be high.
<h3>Describe the connection between wavelength & frequency?</h3>
Frequency and wavelength have an inverse connection with one another. As a result, the wave with a high frequency should have a short wavelength.
For short-wavelength, the frequency will be high.
Hence Option C is correct. It has a high frequency.

Although scientists can't detect or observe black holes with telescopes that detect x-rays, light, or other many other different forms of electromagnetic radiation and waves. But they can detect and study them by the effect of matter near it. If a black hole passes through a cloud of interstellar matter, it will draw matter inward (this process is known as accretion). A similar process occurs when a star passes through a black hole. When this happens, a star can break apart as it pulls it self toward it. As the attracted matter accelerates and starts heating up, it emits x-rays that are radiate into space.
Recent studies do show that black do have a very big influence towards neighborhoods around it. The black hole emits gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.

Answer:
191.36 N/m
Explanation:
From the question,
The Potential Energy of the safe = Energy of the spring when it was compressed.
mgh = 1/2ke²............... Equation 1
Where m = mass of the safe, g = acceleration due to gravity, h = height of the save above the heavy duty spring , k = spring constant, e = compression
Making k the subject of the equation,
k =2mgh/e²................ Equation 2
Given: m = 1100 kg, h = 2.4 mm = 0.0024 m, e = 0.52 m
Constant: g = 9.8 m/s²
Substitute into equation 2
k = 2(1100)(9.8)(0.0024)/0.52²
k = 51.744/0.2704
k = 191.36 N/m
Hence the spring constant of the heavy-duty spring = 191.36 N/m
Answer:
Los cuerpos se encuentran luego de 15 segundos a los 300 metros.
Explanation:
El movimiento rectilíneo uniforme (MRU) es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir, que en este caso el movimiento es lineal en una única dirección y la velocidad de desplazamiento es constante.
La posición del cuerpo después de un tiempo se calcula a partir de la posición inicial y de la velocidad del cuerpo mediante la expresión:
x=x0+v⋅t
donde:
-
x0 es la posición inicial.
- v es la velocidad que tiene el cuerpo a lo largo del movimiento.
- t es el intervalo de tiempo durante el cual se mueve el cuerpo.
En este caso, si el tiempo empleado por el primer cuerpo es t, el del segundo que sale 5 segundos más tarde será t-5. Siendo la velocidad del primer cuerpo 20 m/s y la del segundo cuerpo 30 m/s, entones la posición de cada uno será:
x1 = 20 m/s* t
x2 = 30 m/s* (t - 5 s)
Ambos se encuentran cuando sus posiciones son iguales:
x2=x1
30*(t - 5) = 20*t
30*t - 30*5= 20*t
30*t - 150 = 20 t
30*t - 20*t= 150
10*t= 150
t= 150÷10
t=15 segundos
Reemplazando en la expresiones de posición obtienes:
x1 = 20 m/s* 15 s= 300 m
x2 = 30 m/s* (15 s - 5 s)= 300 m
<u><em>Los cuerpos se encuentran luego de 15 segundos a los 300 metros.</em></u>
