How does the EMF of a battery which is made up of cells in series compare with the EMF of the individual cell?
The EMF of a battery made up of cells in series is equal to the sum of the EMFs of the individual cells. When cells are connected in series, their voltages add up. For example, if you have two 1.5V cells in series, the total EMF of the battery would be 3V.
Why don't they fill the fuel cells with lead shot?
Filling fuel cells with lead shot would not be practical as the purpose of fuel cells is to convert chemical energy directly into electrical energy. Lead shot would not provide a suitable chemical reaction to generate electricity efficiently. Additionally, lead is a toxic material and using it in fuel cells could raise environmental and health concerns.
How can you make solar cells for electricity from solar cells for heating?
To convert solar cells for heating into ones for electricity, you would need to incorporate a material that can convert sunlight into electricity, such as silicon. You would also need to add electrical connections and wiring to collect and transfer the generated electricity. Finally, ensure that the solar cells are properly oriented towards the sun for optimal electricity production.
Robert Hooke and the Hooke law?
Robert Hooke was a 17th-century scientist who formulated Hooke's law, which states that the force needed to extend or compress a spring by a distance is proportional to that distance. This principle is widely used in physics to understand the behavior of springs and elastic materials under stress.
What is the diff between mono cell and poly cell in solar panel?
The cell structure determines the way solar energy is captured. Mono cells are good for direct sunlight, while Poly cells are good for indirect sunlight. As an example you would use mono cell on top of your roof, while you would use poly cells on the side of your house.
If the body cells of an organism have 10 chromosomes then its sex cells would have what?
it is always half so 5 chromosomes. -By SciienceFreak
Can muscle cells extend or get longer as well as contract or get shorter?
False
What are tube like pockets of epidermal cells that extend into the dermis?
Hair follicles are tube-like structures that extend from the epidermis into the dermis. They are comprised of epidermal cells and contain the hair shaft.
What is always found in bacterail cells?
what is always found in bacteraill cells
What happened to the number of cells in a boys body when he grew?
As you grow, the number of cells in your body increases. Your body is also always replacing cells. Cells are always dying and new cells are always being made.
During mitosis in animal cells spindle fibers extend from the centrioles which are located at opposite sides of the cells true or false?
true
Can muscle cells extend?
only contract, never extend. if it looks like it is extending, that's just another muscles contraction.
What would happen to your bodies if blood pH was changed or altered?
You would die because it needs to be between 7.35 and 7.45 for homeostasis a.k.a balance for our bodies If it's too high or low our bodies would not function. It will fail.
Why would mitosis inhibitor be helpful for tumors?
It would reduce the size of the tumor but it would also reduce the number of new cells you would need, like your skin cells. You are always renewing some tissues as they wear out quickly. Only if, somehow ,this inhibitor would act against just cancer cells, would it be practical. The way that it works would be like throwing water on a fire. The growth of new cells would stop.
Do animal cells always have a nucleus?
Yes. Animal cells are Eukaryotic, and therefore always have a nucleus
Is it true that you can select cells using the keyboarding by pressing and holding the control key and using the arrow keys to extend the selection?
No it is not true. You would use the Shift key, not the Ctrl key to do it.
When and why cells are selected?
At any one time there is always at least one cell on a worksheet selected. If you want to do anything with any cells, you have to select them. You cannot do anything without selecting cells. Be it editing, copying, deleting, cutting, pasting, creating charts and so on, you need to select cells. If you could not select cells, then you would have no connection to the worksheet and could no do anything on it. So, when do you select cells? - Always. Why do you select cells? - To do anything you need to do on the worksheet.
