your answer is c) Ends

As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.

Answer: The correct answer is "Ends".

Explanation:

Bar magnet is a permanent magnet.

Bar Magnet has two poles: North pole and South pole.

Same poles repel each other and the opposite poles attract each other.

The magnetic field lines originates from the north pole and ends at the south pole.

The magnetic filed lines are surrounding of the magnet in which the magnetic force can be experienced. The magnetic fields are stronger near the poles of the magnet. As the distances decreases from the poles, the magnetic fields lines get weaker.

Therefore, the correct option is (C).

Sometimes a person cannot clearly see objects close up or far away. To correct this type of vision, bifocals are often used. The

Rudik [331]

Answer:

1) P₁ = -2 D, 2) P₂ = 6 D

Explanation:

for this exercise in geometric optics let's use the equation of the constructor

$\frac{1}{f} = \frac{1}{p} + \frac{1}{q}$

where f is the focal length, p and q are the distance to the object and the image, respectively

1) to see a distant object it must be at infinity (p = ∞)

$\frac{1}{f_1} = \frac{1}{q}$

q = f₁

2) for an object located at p = 25 cm

$\frac{1}{f_2} = \frac{1}{25} + \frac{1}{q}$

We can that in the two expressions we have the distance to the image, this is the distance where it can be seen clearly in general for a normal person is q = 50 cm

we substitute in the equations

1) f₁ = -50 cm

$\frac{1}{f_2} = \frac{1}{25} + \frac{1}{50}$

$\frac{1}{f_2}$ = 0.06

f₂ = 16.67 cm

the expression for the power of the lenses is

P = $\frac{1}{f}$

where the focal length is in meters

1) P₁ = 1/0.50

P₁ = -2 D

2) P₂ = 1 /0.16667

P₂ = 6 D

1) The forces of molecules is how strong they are being held together. Now, we know that solid is the last one, because it's particles are held CLOSELY and VERY TIGHTLY together, which is why it has a definite shape.And last of all, a gas's particles are held freely, which is why it has no shape. So the answer would be:- gas, liquid, solid

3) The state of matter that does not have a definite shape, but has a definite volume is a liquid. So the answer is :- liquid

7) False, an endothermic reaction is when it absorbs energy, and as we know that in a chemical reaction as the following, it tends to be an exothermic reaction, meaning that is releases energy. So the answer is:- FALSE

8) Gases have particles that are far apart (freely) and move fast. So the answer is:- They are moving very fast and are far apart.<span> </span>
