Answer:
Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. Faster-vibrating particles bump into one another more often and hit each other harder. ... When a sample of solid, liquid, or gas matter cools down, it contracts. When matter cools down, its particles lose kinetic energy.
Answer:
Step-by-step explanation:
We want to simplify:
We rewrite as positive index to get:
This simplifies to
This will finally give us:
We cannot simplify further.
Hence the simplest form is
Ok so how I get taught to do this is you need to know the basics of algebra if you know that then respond and I’ll tell you how to solve that
The modulus of complex number can be computed with this equation:
|z|=sqrt(Re(z)^2+Im(z)^2)
z = -2-6i
Re(z)=-2, so Re(z)^2=4
Im(z)=-6, so Im(z)^2=36
|z|=sqrt(36+4)=sqrt(40)=6.3
