A compass has a magnitized needle that follows magnetic fields in the earth to lead you to the South I believe because of how strong the magnetic pull is.

Answer:

Compasses work so effortlessly because their design allows the magnet to respond freely to Earth's magnetic field. Earth itself is like a giant magnet that creates its own magnetic field. The north end of a compass is drawn to align with Earth's magnetic North Pole

...

A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)

Bonus: What is the velocity of an 8 kg lead shot-put if it has 484 J of energy? Type here to search e​
Dima020 [189]

Answer:

11m/s

Explanation:

Given parameters:

Mass of the lead shot = 8kg

Energy of the shot  = 484J

Unknown:

Velocity of the shot  = ?

Solution:

To solve this problem, we apply the kinetic energy formula;

        K.E  = \frac{1}{2} m v²  

m is the mass

v is the unknown

 Now, insert the parameters and solve;

        484  = \frac{1}{2} x 8 x v²

        484  = 4v²

           v² = 121

            v  = 11m/s

A block of aluminum measures 4.0 cm x 5.0 cm x 2.0 cm is completely immersed in a tank of water.
Aneli [31]

Answer:

upthrust or BUOYANT FORCE =Vdg

volume=LWH

upthrust=(4cm×5cm×2cm)×1g/cm²×g

upthrust=40cm³×1g/cm³×g

upthrust=40gf or 0.04kg×10m/s²=0.4N

weight of the displaced liquid is upthrust.

so mass=40g or 0.04kg

upthrust=40gf or 0.4Nand mass of the displaced liquid=40g or 0.04kg

please mark brainliest, hope it helped
