How do you determine the electrical charge of an atom? The charge of an atom is the number of protons minus the number of electrons. Usually, these two numbers are equal, so the atom is neutral (charge of zero).
Where do electric eels lay their eggs? During the dry season, female electric eels lay their eggs in a foam nest made of saliva. Males are responsible for building the nest of spit and guarding the eggs until they hatch during the rainy season. An average of 1,200 baby eels will hatch from the well-guarded nest.
How do electric eels have babies? These nests are made with the saliva of the male. Males fertilize the eggs, which can add up to 1,700 each year by the female. Once the eggs are in the nest and fertilized, the eels die. The eggs slowly hatch, floating to the surface of the water after they become larvae.
Where are eels born? Its birthplace is in the Sargasso Sea, part of the Atlantic Ocean southeast of Bermuda. From the Sargasso Sea, ocean currents carry baby eels to the coast of North America.
How do you determine the electrical charge of an atom? – Related Questions
What carries electricity generated by neurons?
Neurons carry messages in the form of electrical signals known as “nerve impulses” which travel along the axon of the neuron. The task of most neurons is to receive signals from neighboring neurons, then transmit them on to another adjacent one.
How much is electric heat a month for an apartment?
The average cost to heat an apartment is approximately typically around $80-100 per month during the winter months if you have gas heat or forced air. However, if you have oil heating, the cost to heat your apartment will be quite a bit more, likely between $200-$250 per month.
What cars have both an electric and hybrid engine?
The Toyota Prius, Ford Escape Hybrid, and Ford Fusion Hybrid are examples of full hybrids, as these cars can be moved forward on battery power alone. A large, high-capacity battery pack is needed for battery-only operation.
How solar cells convert light to electricity?
When light energy from the sun strikes a photovoltaic solar cell, it energizes the cell and causes electrons to ‘come loose’ from atoms within the semiconductor wafer. Those loose electrons are set into motion by the electric field surrounding the wafer, and this motion creates an electrical current.
Are most dryers electric or gas?
Gas Dryer. Most every dryer will come either as a gas or electric version. Gas dryers cost more to purchase, approximately $50 to $100 more, than the comparable electric model. That’s because the components for gas dryers are more expensive than those that electric dryers.
How to know how much electricity you use?
To get specifics regarding your energy usage, you only need one tool, really: an electricity usage monitor that tells you exactly how many kWh a device or appliance is drawing. The monitor can be as simple as a “plug load” monitor that plugs into an outlet; then you plug the device/appliance into the monitor.
How can electricity be used to create a magnetic field?
As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
Can touching an electric fence kill you?
Can an electric fence kill you? An electric fence is not dangerous since the amplification or current being sent through wires is very low. It’s the amps that could ultimately kill and with an electric fence you’ll usually see it at a low setting of around 120 milliamps.
Do electric cars do emissions testing?
Electric vehicles (EVs) have no tailpipe emissions. … Learn more about electricity production in your area. EPA and DOE’s Beyond Tailpipe Emissions Calculator can help you estimate the greenhouse gas emissions associated with charging and driving an EV or a plug-in hybrid electric vehicle (PHEV) where you live.
How is electricity moved by the national grid?
Electricity is generated at power plants and moves through a complex system, sometimes called the grid, of electricity substations, transformers, and power lines that connect electricity producers and consumers.
Is an expansion tank required on an electric water heater?
So, are water heater expansion tanks required? Most cities require residential plumbing systems to be closed water heater systems. When a new water heater is installed on a closed system, an expansion tank is required by building codes. Expansion tanks are not required for open plumbing systems.
Can i cover an electrical box with drywall?
As long as there are no wires inside the box, you can cover it with drywall. If the box is still acting as a junction box, however, and wires are joined inside it, the electrical code mandates a removable cover. … Remove the power cable from the electrical box.
Why does my electric guitar sound tinny?
Guitar Sounds Tinny. Your guitar can sound tinny or metallic due to switching to brand new strings, bad action height, pedal or amp settings, or due to thin-sounding pickups. If you are hearing a tinny sound when recording an electric guitar, it may be caused by your recording hardware.
How often should you add wood chips to electric smoker?
What is this? Generally, 1 cup of wood chips will last 4 -5 hours. Continue to monitor your smoke levels without opening the smoker door. Add a handful of wood chips every 4 hours or so until the cooking time is completed.
Which electric cooktops don’t scratch?
The glass ceramic cooktops are scratch resistant, yet not scratch proof. Check the bottoms of the pans that you use for any rough spots or burned food pieces. The bottoms of the pans should be a “smooth” flat surface. Proper cookware should be used.
How to trace broken electrical wire?
Place the black end of the multimeter into the round ground port of the device. Place the red in the smaller of the two slotted ports on the device. Make sure the leads are connected to metal in order for the multimeter to work properly. If the resistance is zero, you’ve found the break.
Can electric fields affect light?
Not normally. Electric and magnetic fields only directly act on electrical charge, and light has no electrical charge. However, in the case of extremely strong electric fields, quantum effects can cause the scattering of photons: Delbrück scattering .
Do electric pianos go out of tune?
Digital pianos and keyboards can be out of tune relative to 440 Hz. … Digital pianos/keyboards just use built-in pre-recorded sounds, so there is no mechanism that can gradually become out of tune in the way that the strings of acoustic pianos do over time.
Can a landlord turn off electricity without notice?
It is illegal for your landlord to shut off the utilities on purpose or because of negligence. It is usually best to try to work it out with your landlord first. Make sure you get any agreement in writing. Second, you must send a written notice to your landlord in order to take next steps.
