Answer:
Maybe when you bump into the refrigerator and the magnet falls?
Explanation:
This is an example of you interacting with electromagnetics because you must have bumped into something and made a magnet fall.
I hope it helps?
If it does help can I have a brainliest?
Answer:
t = -4/3 s, t = 4/3 s
Explanation:
I am ASSUMING that you want to know the time(s) the particle is at rest.
and that your position equation is x(t) = 16t − 3.0t³
IF those assumptions are true
THEN
velocity is the derivative of position
v(t) = 16 - 9t²
the particle will be at rest when velocity is zero
0 = 16 - 9t²
9t² = 16
t² = 16/9
t = ± 4/3
Answer:
The value is
Explanation:
From the question we are told that
The distance of separation is
The current on the one wire is
The current on the second wire is
Generally the magnitude of the field exerted between the current carrying wire is
Here is the magnetic field due to the first wire which is mathematically represented as
Here is the distance to the half way point of the separation and the value is
is the magnetic field due to the first wire which is mathematically represented as

Answer:
"Wave 3 resulted from constructive interference and Wave 4 resulted from destructive interference."
Explanation:
Constructive Interference:
When two waves meet in such a way that their crests line up together, then it's called constructive interference. The resulting wave has a higher amplitude.
Destructive Interference:
In destructive interference, the crest of one wave meets the trough of another, and the result is a lower total amplitude.
The amplitude of Wave 3 is higher than both the Waves, 1 & 2, so it must be a result of constructive interference.
The amplitude of Wave 4 is less than both the Waves, 1 & 2, so it must be a result of destructive interference.
<span>So when a glass marble is rubbed against a silk cloth, the silk cloth acquires some electron from glass marble. So the from the given option two statements apply to the situation, the marble has lost the same number of electrons acquired by the piece of silk and the marble acquires a positive charge and attracts the piece of silk.</span>
