1) The object slows down due to kinetic friction.
2) The coefficient of kinetic friction is higher on a carpet than on the bare floor, therefore the object would slow down quicker on the carpet
The earth all the way around is 196.9 million miles
Answer: Normal polarity
Explanation:
Magnetic field in line with the earth field is said to have polarity.
If the magnetic field is in opposite direction with the earth's field, then, the polarity is said to be a reversed polarity.
But since the magnetic field is with the same orientation as the Earth's field, it is said to have normal polarity.
Explanation:
Two objects that only have the force of gravity acting on them, will fall with the same acceleration <span>g=9.8<span>m<span>s2</span></span>; g=32.2<span><span>ft</span><span>s2</span></span></span> and will therefore hit the ground at the same time.
When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.
Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.
hope this can give u a little bet more to know about how to get ur answer :P
have a gud day and gud luck!
