Answer:
Repulsion
Explanation:
Every magnet has two poles: North and South. Magnets have a property that they attract or repel another magnet and iron-nickel objects. But whether two magnets will attract or repel each other depends on how they are brought together. If unlike poles are brought near the magnets will attract. If like poles are brought near then they will repel each other.
Here north pole of one magnet will repel north pole of another magnet.
Answer:
velocity of girl with respect to surface of ice 1.154 m/s
Explanation:
Plank Mass , M = 150 kg
Girl Mass , m = 45 kg
velocity of the girl with resect to plank, v1 = 1.50 m/s
velocity of the plank + girl = v2
from the conservation of momentum
Momentum (plank+girl) = - momentum of the girl
(M+m)v2 = -mv1
v2 = -(45 kg)/(195 kg) * 1.50
v2 = -0.346 m/s
velocity of girl with respect to surface of ice =
v1+v2 = 1.50 + (-0.346) = 1.154 m/s
From Greek meaning not divisible.
Answer:
Hydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8. All others are substantially less common.
Explanation:
<h2>Answer: remain stationary</h2>
Stationary waves (so called because they seem to be immobile) occur when two waves interfere with the <u>same frequency, amplitude but with different direction</u>, along a line with a phase difference of half wavelength.
In this kind of waves there are two types of points:
The nodes, which are points that remain motionless or stationary and do not vibrate. They are due to the destructive interference of both waves when they meet.
The antinodes, which are points that vibrate with a maximum vibration amplitude. They are due to the non-destructive interference of both waves.
According to this explanation and comparing it with the description, when this two waves pass through each other, the point P will become a node, hence<u> it will remain stationary</u>.
