When the magnet is placed on the glass, it is attracted to the iron filings. The pattern of the iron filings shows that the lines of force that make up the magnetic field of the magnet. Also, The lines of force of north and south poles attract each other whereas those of two north poles fend off each other.
"Acceleration" is any change in speed or direction of motion ...
slowing down, speeding up, or curving away from a straight line.
You and I, and all other students of Physics, must re-educate
people. We have to tell everyone that 'acceleration' does NOT
mean 'speeding up'. AND, it doesn't even necessarily mean
any change in speed.
Meter and second is the correct answer.
<u>Answer:</u>
<em>Sand in a beach is warmer than the water of the sea.
</em>
<u>Explanation:</u>
<em>Water absorbs less heat from the sun</em> when compared with sand. Sand is darker and also is less reflective. Because of its darker nature, absorption of heat from the sun will be more. Due to its less reflective nature the sand wouldn’t be able to<em> reflect off the sunlight.
</em>
But water is highly reflective and can reflect off a <em>major portion of the sunlight falling on the sea</em>. The sea is also deep and thus the heat spreads through a large volume unlike in the <em>case of sand.</em> Water also has the nature of constant movement unlike sand which is stable.
<em>This factor also heats up sand more than water.
</em>
