Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.Magnets are important because of their properties A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a particle in motion.

uake formation? Select three options.

Answers

Answer:

- plates moving;

- breaking rocks;

- movement bellow the surface;

Explanation:

The earthquakes are a direct result of the plate tectonics. In order for an earthquake to appear, there should be a geologic activity caused by the movement of the tectonic plates. The movement of the tectonic plates causes a lot of pressure on the rocks. The rocks eventually break at certain places under the pressure. A they break, there's movement bellow the surface, or rather inside the crust, also referred to as adjustment. That movement and the release of power from it, causes lot of strong vibrations. The vibrations spread out and start shaking the ground in the surrounding area, which is actually the earthquake itself.

if hcf is 192 then what is lcm​

Answers

Answer:

LCM = 40320

Explanation:

This question is incomplete as we are not told the numbers that was used to derive the HCF.

Let's consider the following question:

The HCF of two numbers 2880 and 2688 is 192. What is the LCM?

Solution:

HCF means = highest common factor

LCM = lowest common multiple

Find attached the solution to the question.

The HCF is found by Picking the factors (prime numbers) common to both numbers. These factors are multiplied together to get the highest common factor.

The LCM is found by picking the factors common to both numbers and the remaining factors not common to both. These are then multiplied to get the lowest common multiple of the two numbers

In this case, the factors common = HCF = 2×2×2×2×2×2×3

Factors not common to both numbers =2×3×5×7

the LCM = 2×2×2×2×2×2×3 ×2×3×5×7

= 2×2×2×2×2×2×2×3×3×5×7

LCM = 40320
