Answer:
TRUE
Explanation:
An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.
Hence the answer is TRUE.
the significant figures is 5 and decimals is 6
Answer:
this is the reason why scientists opt to transmit data at lower frequency instead of electromagnetic even it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
Explanation:
Communication refers to the process of conducting and obtaining information in the form of signals. The electromagnetic waves are used by the high technology communications systems, and there are different kinds of electromagnetic waves, which are utilized like microwaves, infrared, radio waves, and others.
However, there are some of the limitations with the applications of electromagnetic waves:
1. Due to a confined number of broadcast frequencies, the application of transmitters must be restricted in a certain manner or they will lead to interference.
2. The physical features like buildings and mountains can interfere or prevent certain transmissions.
3. In the air, the signals can be misleaded due to atmospheric conditions and the signals from the space are at certain occasions get distorted by solar activity.
Yes! Exposure to formaldehyde even once can irritate the eyes and respiratory tract.
