What characteristic of electricity is expressed in watts?
electric energy
What is the relative penetrating power of alpha?
Alpha Particles have very poor penetrating power. They can usually be stopped by an inch or so of air, or a sheet or two of paper, depending on their energy. However, because of their charge, they can be quite destructive.
What is the connection between the ionising power of radiation and its penetrating power?
Low ionising power results from great penetrating power.
How can convert active power to reactive power and apparent power too?
'Active' power describes the rate at which energy is delivered to a load and is permanently lost, and is expressed in watts. 'Reactive' power describes the rate at which energy is alternately stored within a magnetic or electric field and returned to the supply every quarter-cycle, and is expressed in reactive volt amperes.You cannot 'convert' one to the other.'Apparent' power is the vectorial sum of active power and reactive power, and is expressed in volt amperes.
What is the unit of watt?
A watt is a unit of power, and it can also be expressed as one joule of energy per second.
Why the ionizing and penetrating power of alpha beta and gama rays varies?
Because there are considerable difference between the three, with respect to electric charge, mass, and energy.
What type of penetrating power does beta particles have?
Beta particles have a very low penetrating power; an aluminium foil of 3-4 mm is a sufficient shielding.
What type of particles has the most penetrating power?
the neutrino
What is a quantity that measures the rate at which work is done?
Work is usually measured in joules, which are a unit of energy. Work/time is called power and is usually measured in Watts (joules/second) other common units of power include Horsepower and ft*lbs /sec. in short, is is power, which is measures in watts.
What is the use of reactive power in electric circuitry?
'Reactive Power', which is expressed in reactive volt amperes, describes the rate at which energy is alternately stored (in a circuit's electric or magnetic field) and returned to the a.c. supply when the field collapses. It differs from true power, expressed in watts, because true power describes the rate at which energy is permanently lost by heat transfer due to the resistive component of the circuit.Reactive power doesn't 'have an use', per se, it's merely a way of quantifying the movement of energy in the reactive component of an a.c. circuit.The vector sum of a circuit's reactive power and its true power is called the apparent power of the circuit, expressed in volt amperes.
The radioactive emission with the weakest penetrating power is the?
alpha ray.
Which type of radiation has the has the greatest penetrating power?
Gamma Ray
