X = v0+ 1/2 a t^2
X= 0+1/2(12 m/s^2 ) ( 7 s)^ 2
X= 6 m/s^2 ( 49 s^2)
X= 294 m
Answer: Option D and E
Explanation: Across the electromagnet spectrum, the frequency increases but the wavelength reduces.
This implies that radio waves have the longest wavelength but the smallest frequency, while gamma rays have the shortest wavelength but the highest frequency.
This implies that there is an inverse relationship between wavelength and frequency.
Of all the technologies listed above, wireless internet has the highest frequency hence making it have the shortest wavelength.
Also by comparing values from the data given to us above, it is possible for some wireless internet device to operate within the same frequency range of the microwave.
Answer:
Kindly find the graphs attached
Explanation:
For figure 1: There is a steady increase in the position of the object as time increases. This is because despite the negative acceleration (deceleration), the object continues to move and cover more ground as time goes by.
<em>The straight line graph is observed because the acceleration is constant and not varying.</em>
For Figure 2: The graph of velocity vs time will have an inverted nature. This is because since the object is decelerating, it is reducing in its velocity as time goes by (increases). <em>This is also in a straight line since the deceleration is constant.</em>
