Hi there! Hopefully this helps!
-------------------------------------------------------------------------------------------------
The SI system of amplitude is a metre (m).
I think it’s when the sun explodes because since we need to the sun I think the human population will fall out. also a huge war, a meteoroid huge as the one that killed the dinosaurs comes down, there is so much ways on how the human population can stop growing. hope this help at least!
Answer:Magnitude of the butterfly's displacement is 11.4 m
Explanation:
from the above figure x distance is from center of the garden to edge = 7 m
height of the tree is y= 9 m
magnitude of the butterfly's displacement is
=
=
=11.4 m
The de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.
<h3>What is wavelength?</h3>
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
Hence,the de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.

Answer:
<em>1. If the switch is closed, the total resistance of the circuit remains the same</em>
<em>2. The brightness of the bulb A when the switch is closed remains the same.</em>
<em></em>
Explanation:
An ideal battery has no internal resistance, and hence, maintains a constant value of voltage without diminishing. The total resistance of the circuit will remain constant since this is an inherent unchanging property of a conducting circuit provided there is no change to its configurations. The brightness of the bulb A will remain unchanged since we are considering an ideal battery. In practice, ideal batteries don't exist, reason why battery powered light bulbs gradually dim with time as the internal resistance increases, till it eventually dies.
