Electricity may be categorized as static or current. how are these two types of energy different
arlik [135]
Hello!

Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.

Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)

Describe how molecules enter and leave a cell without the use of the cell’s energy
HACTEHA [7]

Answer:

Through passive transport

Explanation:

<em>Passive transport is the movement of molecules and ions across the cell membrane whith no use of energy,</em> it usuale involves a difussion down its concentration gradient (a region where concentration changes) across a membrane, from higher to lower concentrations. Passive transport can happen by simple diffusion, facilitated diffusion, filtration, or osmosis.

I hope you find this information useful and interesting! Good luck!

The total energy need during pregnancy is normally distributed, with mean Mu = 2600 kcal/day and standard deviation = 50 kcal/da
Digiron [165]
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.

z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.

Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
