Suppose a sound wave and an electromagnetic wave have the same frequency. Which has the longer wavelength? 1. the electromagneti
Mashcka [7]

Answer:

1. the electromagnetic wave.

Explanation:

Mathematically,

wavelength = velocity ÷ frequency

A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.

Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter, increasing frequency decreases wavelength.

Sound waves (which obviously travel at the speed of sound) are much slower than electromagnetic waves (which travel at the speed of light.)  

Electromagnetic waves are much faster than sound waves and If the Velocity of the wave increases and the frequency is constant, the wavelength also increases.

In addition to National Electrical Code requirements, some areas have ___ requirements for energy conservation that also affect
Alex777 [14]

Answer:

building code

Explanation:

National Electrical Code establishes the minimum conditions that must be met by electrical installations to preserve the safety of people and property, as well as ensure the reliability of their operation. It applies to installations in buildings destined for homes, shops, offices and for facilities in premises where similar functions are fulfilled, including temporary or provisional ones.

The construction code is something extra to help the conservation of energy of the building affecting the provision of energy even its luminaries. This type of code is chosen to increase the sustainability of said building .

This 200-kg horse ran the track at a speed of 5 m/s. What was the average kinetic energy?
MrRissso [65]

Answer:

<h2>2500 J</h2>

Explanation:

The average kinetic energy can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 200 \times  {5}^{2} \\   = 100 \times 25

We have the final answer is

<h3>2500 J</h3>

Hope this helps you
