What is the use of ground plane in helical antenna?
A ground plane in a helical antenna acts as a reflector, enhancing the radiation pattern and efficiency of the antenna. It helps to direct the radiated signal in a desired direction and minimizes signal loss due to ground reflections. The ground plane also provides a stable reference point for the antenna structure.
What is the frame reference for a plane moving at 500 kmh?
The frame of reference for a plane moving at 500 km/h can be considered as the inside of the plane itself. This means that the speed and movement of objects inside the plane are relative to the plane's motion, while the ground outside may appear to be moving rapidly in the opposite direction.
What are the forces on a plane when it is still?
When a plane is still on the ground, the main forces acting on it are weight and normal force. Weight is the force due to gravity acting downward, while the normal force is the force exerted by the ground perpendicular to the plane to support its weight. Additionally, there may be frictional forces acting on the wheels to prevent the plane from moving.
What is the frame of reference for a plane moving at 500 km h?
The frame of reference for a plane moving at 500 km/h could be relative to the ground or the air. The ground frame of reference would consider the plane's speed relative to the Earth's surface. The air frame of reference would consider the plane's speed relative to the surrounding air.
An apple falls from a tree and 1s later hits the ground. How fast is it falling when it hits the ground?
Assuming the acceleration due to gravity is 9.8 m/s², the apple would be falling at 9.8 m/s when it hits the ground after 1 second.
How do you use the word unctuous in a sentence?
The compound was unctuous and smooth.
What is a sentence for the word unctuous?
i was unctuous about math.many peole are unconscious
Why aren't passengers usually injured when lightning hits a plane?
The lightning has no path to ground.
Can you use unctuous in a sentence?
The soap felt unctuous when it slipped from my hands.
How many deaths occur in plane accidents?
It depends on how many people are in the plane. Most people die in plane crashes (if in plane)because of the impact of it when the plane hits the ground. People who don't die will be badly injured and very blessed they didn't die.
What are some synonyms of unctuous?
The synonyms of unctuous are ingratiating, buttery, insincere, smarmy, smooth and suave. These synonyms can also be checked in any English dictionary.
Whats another word for unctuous?
Smarmy, obsequious.
Landed as a plane?
on the ground
Fly the plane or drive the plane?
Both - you fly it in the air, but you drive it on the ground.
What would hit the ground first a human or a plane?
Depending were the human and the plane were at. if the human was on the ground and the plane in the air then the human, but lets say they are both 30,000 feet in the air. Both objects would begin to fall faster, then it gets to the point were they are going their "maximum" speed. But they weight between each objects will have an "impact" on who hits the ground first. The plane is obviously heavier than the person but gravity will come into play. There is a point were a falling object cannot go any faster. Most likely both objects will be falling at the same speed. So they could hit the ground at the same time.
Does 102 fiberglass CB antenna require ground plane?
Yes, it does, unless it's part of a "no ground plane" kit. "No ground plane" is a misnomer, since the outer conductor on the coax is in fact the ground plane in these kits and is a specially made and tuned part that should not be altered. The fiberglass whip that you're asking about is actually 1/2 of a dipole, the other half is the ground plane. Both must work together for efficient signal propagation and be tuned in the mounted location.
Is a batter awarded first base if the ball hits the ground first in womens fast pitch softball?
If it hits the ground then hits the batter then yes. If it just hits the ground then no.
