Actually says Pantazis, since their frequencies are so wildly different, brain waves don’t interfere with radio waves. Even if that was the case, brain waves are so weak, they are hardly measurable at all. For comparison, says Pantazis, “the magnetic field of the earth is just strong enough to move the needle of a compass. Signals from the brain are a billionth of that strength.”
Answer:
The nest must be about 4.15 meters above ground
Explanation:
Use the velocity equation under accelerated motion (acceleration of gravity ):
which for this case has initial velocity = 0 (falls from the nest), final velocity = 9 m/s, and a = 9.8 m/s^2, then we can find the time needed in air while falling to reach the required speed:
We now use this time value to find the distance covered in free fall during 0.92 seconds:
Different types of fronts produce different patterns of weather. When a cold, dense air mass pushes warmer air, it produces a cold front. A cold front can turn a heat wave into normal summer weather or turn cold winter air into very cold weather. Cold fronts often produce tall cumulonimbus clouds.
(20 seconds / 40 vibes) = (20/40) (seconds/vibe) = 0.5 second
Answer:
The electric field is entering the sheet
Explanation:
When the electron enters the region with the two fields, each one feels a force, so that the direction of the electron is altered, the sum of these two forces is zero.
Let's look for the direction of the magnetic force, for a positive charge, using the rule of the right hand, where the thumb goes in the direction of the velocity of the particle, the fingers extended in the direction of the magnetic field and the palm is in the direction of the strength
Let us apply this rule our case, the thumb goes the x axis and the fingers on the Y axis, therefore, the force is coming out of the sheet, if the load were positive, but with negative the magnetic outside is entering the leaf
The electric force is F = q.E.
For the resultant to be zero the electric force must leave the sheet and as our charge is negative The electric field is entering the sheet
