Is it possible that the cannonball will miss the ground?
hell no
An atom in its lowest possible energy state is in what state?
Ground state
Is it possible to have force in the absence of a motion?
Yes, anything on the surface of the planet which is at rest exerts a force on the ground and the ground exerts a force on it.
The lowest possible energy position for an electron is known as the ground state?
yes
What is the state when all electrons of an atom are in the lowest possible energy levels?
whenever they are in there most stable state , then they are at their lowest energy level. as u provide energy , they get excited and then upgrade to further energy level . and due to loss of energy , they regain earlier positions.
Definition of guided unguided media?
The unguided media is the wireless media. It simply transports electromagnetic waves without using any physical conductor. Signals are normally broadcast through the air and thus are available to any one who has the device capable of receiving them. Unguided signals can be travelled from source to the destination in several ways. These ways include ground propagation, sky propagation and line of sight propagation.
What makes the signals sometimes not work on a 2002 impala?
possible bad turn signal switch in the steering column or a bad ground on your turn signals.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation
What is the disadwantege of ground wave propagation?
Ground Wave propagation is sometime unreliable due to the conditions at the surface or topography that the ground waves may encounter. Iron deposits, humidity or water )lack of or over abundance of) ,vegetation etc. On the other hand when using ground wave propagation in barren terrain can be used quite effectively because of the lack of variables. Propagation over large bodies of water (Atlantic, Pacific Oceans) is relatively reliable.
Can sound transmit through the ground?
yes
What is the difference between AGND and DGND?
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.
What important role do the ions in the ionosphere play in making the use of technology possible?
They are being used by radio station to transmit signals from one station to another. Thanks to the property of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can be utilized to "bounce" a transmitted signal down to ground
What signals the end of Germination?
When the plant stem is above ground
What property of electromagnetic waves makes it possible to use waves to transmit information between a space shuttle and NASA mission control centers on the ground?
Mainly the fact that such waves can travel through empty space.
Which seismic wave causes particles in the ground to move perpendicular to the wave's propagation?
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
What has the author James A Kearns written?
James A Kearns has written: 'Sound propagation over uneven ground and irregular topography'
What are the advantages of adcock df over loop antenna?
As far as I know ... The Adcock DF works with signals, which are reflected at the ionosphere and with ground wave signals ... the loop antenna works only wich ground wave signals, not with bounced signals from ionosphere ... and, by the way, the Doppler DF works also only with ground wave signals ... so for long distance DF at shortwave, the best (and only good) working DF ist the Adcock system ... sorry about my poor english :) Dietmar, DL4HAO
