"two pieces of iron attract eachother. how can you tell whether they are both magnets?"

1 answer:

5 0

Answer: A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

If two metal, say iron , attract each other it shows a magnetic pull. Also metal can attract other metal only if it has magnetic fields. Remember to note that the metal should attract Ferromagnetic materials only.

A sled with mass 8.00kg moves in a straight line on a frictionless horizontal surface. At one point in it's path, it's speed is

kati45 [8]

We will use two definitions to solve this problem. The first will be given by the conservation of energy, whereby the change in kinetic energy must be equivalent to work. At the same time, work can be defined as the product between the force by the distance traveled. By matching these two expressions and clearing for the Force we can find the desired variable.

$W = KE_f-KE_i$

$Fd = \frac{1}{2}mv_f^2-\frac{1}{2} mv_i^2$

Thus the force acting on the sled is,

$F = \frac{m}{2s} (v_f^2-v_i^2)$

Replacing,

$F = \frac{8}{2(2.5)}(6^2-4^2)$

$F = 32N$

Therefore the Force acting on the sled is 32N

A lumberjack is chopping wood with an ax. How does the ax make the lumberjack's job easier? A. The ax is heavy so it can split w

zhenek [66]

Answer: B

Explanation:

A machine multiplies the work output of a something by some amount. In this question, the ax is the machine. Thus, the ax is multiplying the work outputted by the lumberjack, so the answer is B. The reason it is not C is because there could be other forces interacting on the wood which the ax can affect.
