Answer:
An attractive force between the magnets. A is the correct answer if it was the north pole facing another north pole magnet the answer would have been a repulsive force between the magnets because the north pole of a magnet does not attract instead it separates from each other which is a repulsive force the best answer is A.
Explanation:
the southern pole of a magnet is a positive force while the northern pole of a magnet is negative .
Note: Magnet can attract each other only when they are facing the opposite directions a north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away.
Answer:
b) se duplica
Explanation:
The disk is moving with constant angular velocity, let's call it 
.
The linear velocity of a point on the disk is given by
where r is the distance of the point from the axis of rotation.
In this problem, the object is moved at a distance twice as far as the initial point, so
Therefore, the new linear velocity is
So, the velocity has doubled, and the correct answer is
b) se duplica
Answer:
<u>2600 cubic centimeters</u>
Explanation:
Volume of the edible fruit is equal to :
⇒ Volume (fruit) - Volume (seed)
⇒ 4/3π(3r)³ - 4/3πr³
⇒ 27 x 4/3πr³ - 4/3πr³
⇒ 100 (27 - 1)
<u>⇒ 2600 cubic centimeters</u>
