#1 explain why there is no such thing as a quick and easy way to lose weight.

Exercise is a vigorous activity that tends to help us to burn calories and loose weight in the process.

<h3>What is exercise?</h3>

Exercise is a vigorous activity that tends to help us to burn calories and loose weight in the process. There is no quick way to loose weight because the calories were added on gradually and must also be lost gradually.

Before and after photos does not show the loss in calories. This can only be determined by measurement.

Before you buy exercise equipment;

  • Ensure that the equipment meets your unique needs
  • Ensure that you can afford it
  • Ensure that you have enough space to contain the equipment

An example of an exercise equipment is a stationary bicycle. It works when you sit or stand on it and cycle repeatedly though it doesn't move. I am skeptical about it because it may not help you burn a lot of calories except you use it for long periods of time.

What is speed of wave in terms of frequency and wavelength??​
ratelena [41]

Answer:

In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s.

Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
