An angle that is between 90 degrees and 180 degrees is called an obtuse angle.
Ex. : 175 degrees, 140 degrees.
first of all electromagnetic waves are energy waves. and we call electromagnetic waves RADIATION.
Voltage . . . DC voltmeter
Current . . . DC ammeter
The "ohmmeter" is also fundamentally a DC ammeter at heart.
Frequency . . . DC doesn't have frequency.
There are three global circulation cells - Hadley cell, Ferrel cell, and Polar cell. Their primary roles are directing the flow of air on the planet.
A+ is forces and motion
it is safer and you can easily reduce the current
Nine volts is equal to zero volts. Watts are the product of amps times volts. An amperage must be multiplied by the voltage to produce a wattage value.
Anode & Cathode
No, the steam engine is an external combustion engine because the steam is heated by heat generated by combustion outside externally through heat transfer.
A spark ignition engine is an example of an internal combustion engine.
Depending on the type of current which are direct current and alternating current,direct current travels in one direction while alternating current travels in a varying direction to the flow of current
Inertia is the property of matter by which it remains in constant, uniform motion unless acted upon by an external force.
Gravity is an ever-present external force.
An integrated circuit contains multiple diodes and transistors on silicon. A processor performs the calculations in a computer.
An electromagnetic wave is a stream of photons which behaves both like waves and particles. They move perpendicular to the direction of propagation. They have 2 mutually perpendicular components of electric and magnetic fields.
Devices that convert electrical energy to heat normally have a resistance that does that.
forces and motion
Strength of electric field is inversely proportional to the square of the distance right from the positive charge
