Sure, here are the answers:

Why materials are good conductors of heat and electricity?

Materials are good conductors of heat and electricity because they have electrons that are free to move around within the material. These free electrons allow for the easy transfer of heat or electricity through the material, as they can carry the energy from one place to another.

Importance of materials in a flashlight

The materials used in a flashlight are important because they need to be good conductors of electricity to ensure that the electrical energy from the battery can power the bulb. The materials also need to be able to withstand the heat generated by the bulb without melting or deforming.

Importance of materials in a toaster

The materials used in a toaster are important because they need to be good conductors of heat to ensure that the bread is toasted evenly. The materials also need to be able to withstand the high temperatures generated by the heating elements without melting or warping.

Importance of materials in a kettle

The materials used in a kettle are important because they need to be good conductors of heat to ensure that the water is heated quickly and efficiently. The materials also need to be able to withstand the high temperatures generated by the heating element without melting or degrading over time.

Importance of materials in an incubator

The materials used in an incubator are important because they need to be good insulators of heat to ensure that the internal temperature remains stable and consistent. The materials also need to be able to withstand the high temperatures required for incubation without melting or releasing harmful chemicals.

Importance of materials in a factory

The materials used in a factory are important because they need to be strong, durable, and able to withstand the wear and tear of daily use. The materials also need to be able to resist corrosion and other forms of degradation caused by exposure to chemicals, heat, and other environmental factors. Additionally, some materials used in factories may need to be good conductors or insulators of heat or electricity, depending on the specific application.

One base of a trapezoid is 8 cm less than thrice the other. If the median measures 12 cm, what is the length of the longer base? Medjan= (B₁+B₂)

B1 =x

B2= 3x-8

median= 12

The formula for the median of a trapezoid is:

Median = (Base 1 + Base 2) / 2

We know that Base 1 is x and Base 2 is 3x - 8, so we can substitute these values into the formula:

12 = (x + 3x - 8) / 2

Multiplying both sides by 2, we get:

24 = 4x - 8

Adding 8 to both sides, we get:

32 = 4x

Dividing both sides by 4, we get:

x = 8

So the shorter base is 8 cm, and the longer base (which is 3 times the shorter base minus 8) is:

3x - 8 = 3(8) - 8 = 16 cm

Therefore, the length of the longer base is 16 cm.
