Assume that a country’s economy is in a short-run equilibrium and the actual unemployment rate is lower than
1 answer:
Answer:
Explanation:
if truly rate of actual unemployment is lower compared to the natural unemployment, it implies that the economy is making a greater effort for higher output level than its potential output.
Lower unemployment than natural rate of unemployment will reflect as lower availability of workers in the economy ,so unions and workers start demanding more wages ,which leads to increase in production cost of firms . Increase in production cost ,leads to decrease in firms supply and short run aggregate supply curve shifts lefttwards and SRAS keep shift to left till economy reach to full employment or potential GDP.As GDP Decreases no of workers Decreases and employment Decreases.
Conclusion: Short run aggregate supply Decreases and employment Decreases.

Answer:
A) Light is made up of waves.
Explanation:
Light is a form of electromagnetic waves.
Electromagnetic waves consist of electric and magnetic fields that oscillate periodically in a plane perpendicular to the direction of motion of the wave, therefore they are transverse in nature.
All electromagnetic waves travel in a vacuum at the speed of light:
Moreover, electromagnetic waves are classified into 7 different types depending on their frequency and wavelength. From lowest to highest frequency (and so, from longest to shortest wavelength), we have:
Radio waves
Microwaves
Ultraviolet
Visible light
Infrared
X-rays
Gamma rays
Visible light is part of this electromagnetic spectrum, and corresponds to the part of the electromagnetic waves that our eye is able to see. In particular, we perceive waves of different wavelength and frequency as different colors: for instance, violet/blue light corresponds to the shortest wavelength that we can see, while red light corresponds to the longest wavelength that we are able to see.
Also, for visible light wave we can describe their brightness, which corresponds to the intensity of the wave, which is a property of all waves.
So the correct answer is
A) Light is made up of waves
