What is the source of power in a space shuttle?
The space shuttle is powered by three fuel cell power plants. The fuel cells are located under the payload bay area in the forward portion of the space shuttle's midfusalage. The three power cells operate independantly of each other, with each supplying it's own isolated 28-volt DC bus. The fuel cells are made up of a power section and an accessory section. In the power section, hydrogen and oxygen are transformed into electrical power, heat, and water. The accessory section controls and monitors the power section's performance. The water produced from the fuel cells is either used for crew consumption, used for cooling the shuttle's Freon-21 coolant loops, or is dumped overboard as waste water.
Why does a space shuttle carry its own supply of oxygen?
A space shuttle carries its own supply of oxygen to sustain the astronauts' breathing when they are in space where there is no atmosphere. It ensures they have a continuous source of oxygen for respiration during the mission.
Does the heat source for the conviction current in the mantle is the sun?
this answer is true
How many gallons of liquid hydrogen does space shuttle use per minute?
The liquid hydrogen feed line flow rate is 465 pounds per second or a maximum flow of 47,365 gallons per minute. Source: http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/et.html#et-lh2
Where do solar power get its energy from?
Solar power gets its energy from the Sun. Photovoltaic cells in solar panels convert sunlight into electricity by absorbing photons from the sunlight and creating an electric current. This renewable energy source is a clean and sustainable alternative to fossil fuels.
A temporary source of electric current?
A battery.
What is the function of a source in the electric current?
POINTS
What particles create the electric current in a fruit battery?
An electric current is movement of electrons, no matter the source or cause.
One source of constant electric current is a?
Alah
What is a temporary source of an electric current called?
A temporary source of an electric current is called a battery. It converts chemical energy into electrical energy to power devices or circuits.
What do you understand by electric current?
electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.
What is the diffrenece between electric charge and electric current?
Electric charge is a property of matter that determines how it interacts with electromagnetic fields, while electric current is the flow of electric charge through a conductor. In other words, electric charge is the source of electric current, which is the movement of charged particles.
What is the pathway for electric current?
Electric current flows from the power source through a circuit. It moves from the positive terminal of the source, through the wires or conductors, to the load (e.g. a lightbulb), and then returns to the negative terminal of the power source to complete the circuit.
What part of an electrical cicuit produces the electric current?
Either the cell e.g. a battery, if one is included in the circuit. Or a generator such as a dynamo
What is a temporary source of electric current?
A battery is a common temporary source of electric current. When connected to a circuit, a battery transforms stored chemical energy into electrical energy to power devices or equipment. Once the stored energy is depleted, the battery needs to be recharged or replaced to continue providing electric current.
What 3 things do you need to have for electric current?
To have electric current, you need a source of electric potential difference (voltage), a closed circuit that allows the flow of charges, and a conductive material through which the electric charges can move.
What source of heat does a halogen light use?
an electric current passed through it
