Power =Force * Velocity
Velocity = Distance/Time = 2/0.5 = 4 m/s
Therefore,
P = 1000*4 = 4000 W = 4 kW
Perception is the sensory experience of the world. It involves both recognizing environmental stimuli and actions in response to these stimuli. Through the perceptual process, we gain information about the properties and elements of the environment that are critical to our survival.
The carrier frequency remains constant during amplitude modulation. :)
Answer:
One may assume that the planet radiates energy like a blackbody at some temperature according to the Stefan–Boltzmann law. Thermal equilibrium exists when the power supplied by the star is equal to the power emitted by the planet. The temperature at which this balance occurs is the planetary equilibrium temperature.
Explanation:
I believe the answer would be A. because a magnet has both a south and a north pole, and electrical charges are formed by positive and negative forces. Hope I helped!
