Electroencephalography is an electrophysiological monitoring method to record electrical activity on the scalp that has been shown to represent the macroscopic activity of the surface layer of the brain underneath. It is typically non-invasive, with the electrodes placed along the scalp.
Answer:
It will take the person 10 seconds to run a 30-meter city block.
Explanation:
To solve this problem, we must remember the formula for velocity:
velocity = displacement/time
If we plug in the values that we are given, we get:
3 m/s = 30 m/time
We can see from the above equation that our answer should be in seconds, so we can get rid of the units to simplify the equation slightly.
3 = 30/t
Next, we can multiply both sides by t:
3t = 30
Then, we should divide both sides of the equation by 3 to get the variable t alone on the left side of the equation.
t = 10
Therefore, the correct answer is 10 s.
As the distance is tripled, the gravitational acceleration decreases by a factor of 9, and so on. At the surface of the Earth, the acceleration due to gravity is roughly 9.8 m/s2.
Answer:
The vector sum is given as in the attached figures, The resultant position is 2.18 km away from the island at 58.19° South of East.
Explanation:
Step No 01: Select appropriate scale. Here 1cm=1km.
Step No 02: Draw each vector one by one such that the tail of 2nd vector coincides with the head of 1st vector.
Step No 03: After all vectors have been drawn, Draw the resultant vector from tail of first vector to the head of 2nd vector.
Step No 04: Measure the resultant vector via ruler and multiple with the scale.
Step No 05: Measure the angle using the D/Protector.
