Answer:
The resistivity of materials depends on the temperature as ρt = ρ0 [1 + α (T – T0). This is the equation that shows the relationship between the resistivity and the temperature.

Answer:
1800 m/
Explanation:
We know this because of Newton's first law,
, which shows us that the force on an object is equal to its mass times the acceleration it recieves. This means that taking our values of 900N and 0.5kg, and plugging them in,

This is honestly a little strange because the force applied and the acceleration seem ridiculous, and a little strange for an answer. Either the values are not meant to be nearly close to reality, or you made a typo.
The number that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.
<h3>What is regional metamorphism?</h3>
Regional metamorphism occurs when rocks undergoes changes as a result of high temperatures and pressure deep within the earth's crust.
Regional metamorphic rocks are usually foliated or squashed in appearance.
Examples of regional metamorphism rocks are schist and gneiss rocks.
Therefore, the figure that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.

It will cause heat from friction
Answer:10cm3
Explanation:Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. *
