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:
Explanation:you know
circumference of a circle =2*pi*r=?
r=radius of a circle =3m
total distance of 6 revolution =s=6*2*pi*r
again, linear speed =v=s/t=?
t=time =60sec
L=G·d
L=600N·3m=1800J
P=L/Δt=1800J/4s=450W
<h3><u>Answer;</u></h3>
Transmission
<h3><u>Explanation;</u></h3>
- <em><u>Light waves are types of waves that are electromagnetic waves, meaning they do not require material medium for transmission. </u></em>Light is transmitted as a transverse wave such that the vibration of particles is perpendicular to the direction of wave motion.
- <em><u>A material medium enables the transmission of a wave by the vibration of particles, atoms or molecules. </u></em>The vibration of particles in a medium helps in the transmission of a wave such that energy is transferred from one point to another due to the disturbance caused by the wave.
Answer : Option D) 90°N and 90°S
Explanation : The latitudes which are given in the options are the angle to be measured in the direction of north and south respectively taking equator as the central line.
When it is 90°N and 90°S it means it forms an right angle and faces towards north and south respectively with respect to the equator, so there are high chances of pointing towards the Arctic and Antarctic regions respectively; therefore giving greater probability of finding glaciers.
