Answer:
Radiation moves out of the microwave into waves causing heat.
Explanation:
Inside your microwave oven, electrical energy is transformed into EM energy in the magnetron. When the microwave photons interact with food, food molecules are physically agitated, transforming the EM energy into kinetic energy, or energy of movement .

Answer:
Cell Membrane
Explanation:
The cell membrane contains a phospholipid bilayer.
Answer with Explanation:
We are given that
Weight of an ore sample=17.5 N
Tension in the cord=11.2 N
We have to find the total volume and the density of the sample.
We know that
Tension, T=![W-F_b](https://tex.z-dn.net/?f=W-F_b)
=buoyancy force
T=Tension force
W=Weight
By using the formula
![11.2=17.5-F_b](https://tex.z-dn.net/?f=11.2%3D17.5-F_b)
N
![F_b=V_{object}\times \rho_{water}\cdot g](https://tex.z-dn.net/?f=F_b%3DV_%7Bobject%7D%5Ctimes%20%5Crho_%7Bwater%7D%5Ccdot%20g)
Where
=Volume of object
=Density of water
=Acceleration due to gravity
Substitute the values then we get
![6.3=9.8\times 1000\times V_{object}](https://tex.z-dn.net/?f=6.3%3D9.8%5Ctimes%201000%5Ctimes%20V_%7Bobject%7D)
![V_{object}=\frac{6.3}{9.8\times 1000}=6.43\times 10^{-4} m^3](https://tex.z-dn.net/?f=V_%7Bobject%7D%3D%5Cfrac%7B6.3%7D%7B9.8%5Ctimes%201000%7D%3D6.43%5Ctimes%2010%5E%7B-4%7D%20m%5E3)
Volume of sample=![6.43\times 10^{-4} m^3](https://tex.z-dn.net/?f=6.43%5Ctimes%2010%5E%7B-4%7D%20m%5E3)
Density of sample,![\rho_{object}=\frac{Mass}{volume_{object}}](https://tex.z-dn.net/?f=%5Crho_%7Bobject%7D%3D%5Cfrac%7BMass%7D%7Bvolume_%7Bobject%7D%7D)
Where mass of ore sample=1.79 kg
Substitute the values then, we get
![\rho_{object}=\frac{1.79}{6.43\times 10^{-4}}=2.78\times 10^3 kg/m^3](https://tex.z-dn.net/?f=%5Crho_%7Bobject%7D%3D%5Cfrac%7B1.79%7D%7B6.43%5Ctimes%2010%5E%7B-4%7D%7D%3D2.78%5Ctimes%2010%5E3%20kg%2Fm%5E3)
Density of the sample=![2.78\times 10^{3} kgm^{-3}](https://tex.z-dn.net/?f=2.78%5Ctimes%2010%5E%7B3%7D%20kgm%5E%7B-3%7D)
I think the answer to this problem I believe would probably be B. learned optimism. I think it's the closest answer...I THINK
