1.
What is the formal name for drones?
Correct Answer
D. UAV
Explanation
The formal name for drones is UAV, which stands for Unmanned Aerial Vehicle. This term is commonly used to refer to aircraft that are operated remotely or autonomously without a human pilot on board. The use of UAVs has increased significantly in various fields such as military, surveillance, photography, and delivery services.
2.
What does UAV stand for?
Correct Answer
C. Unmanned Aerial Vehicle
Explanation
UAV stands for Unmanned Aerial Vehicle. This term refers to an aircraft that is operated remotely without a pilot on board. These vehicles are typically used for various purposes such as surveillance, reconnaissance, and aerial photography. They are controlled either by an operator on the ground or by pre-programmed instructions. UAVs have become increasingly popular due to their versatility, efficiency, and ability to access areas that may be difficult or dangerous for manned aircraft.
3.
Drones were originally used for agriculture.
Correct Answer
B. False
Explanation
Drones were not originally used for agriculture. While drones have become increasingly popular in agriculture in recent years, their original use was primarily for military purposes. Drones were initially developed for surveillance and reconnaissance missions by the military. It is only in recent years that their potential for agricultural applications, such as crop monitoring and spraying, has been explored and utilized. Therefore, the statement that drones were originally used for agriculture is false.
4.
Drones have ______ not jets. (rotors/motors)
Correct Answer
rotors
Explanation
Drones have rotors, not jets. Rotors are the spinning blades that generate lift and allow drones to fly. Jets, on the other hand, are typically used in aircraft and rely on the propulsion of hot gases expelled from the engine. Therefore, the correct answer is rotors.
5.
Drones can be used for.... (tick all that apply)
Correct Answer(s)
A. Agriculture
C. Surf Lifesaving
D. The Military
Explanation
Drones can be used in agriculture to monitor crops, spray pesticides, and collect data for precision farming. In surf lifesaving, drones can be used to patrol beaches, spot swimmers in distress, and deliver life-saving equipment. The military also utilizes drones for reconnaissance, surveillance, and targeted strikes. Skiing, however, does not typically involve the use of drones.
6.
Some drones can take infrared photos.
Correct Answer
A. True
Explanation
Some drones are equipped with infrared cameras, allowing them to capture infrared photos. Infrared photography is useful in various applications such as surveillance, search and rescue operations, and environmental monitoring. By capturing infrared images, drones can detect heat signatures, identify temperature differences, and provide valuable data for analysis. Therefore, it is true that some drones have the capability to take infrared photos.
7.
How does infrared technology help farmers?
Correct Answer
B. It shows if plants are stressed or if there is any bare earth.
Explanation
Infrared technology helps farmers by showing if plants are stressed or if there is any bare earth. Infrared cameras can detect the heat emitted by plants, which can indicate stress caused by lack of water or nutrient deficiencies. Additionally, infrared imaging can identify areas of bare earth, which may require reseeding or additional attention. This information allows farmers to make informed decisions about irrigation, fertilization, and overall crop health, leading to more efficient and effective farming practices.
8.
Some people are against the use of drones because it breaches their ________. (privacy/confidentiality)
Correct Answer
privacy
Explanation
Some people are against the use of drones because it breaches their privacy. Drones have the ability to capture images and videos from above, which can invade people's personal space and violate their right to privacy. This includes activities such as surveillance, monitoring, and recording without consent. The use of drones in certain areas or situations can lead to concerns about the unauthorized collection and misuse of personal information. Therefore, the breach of privacy is a valid reason for some individuals to oppose the use of drones.
9.
Drones aren't allowed to fly above 120m.
Correct Answer
A. True
Explanation
The given statement states that drones are not allowed to fly above 120m. This means that it is true that drones have a maximum height limit of 120m.
10.
How much can a multi - rotor carry?
Correct Answer
A. 5 kilograms
Explanation
A multi-rotor can carry up to 5 kilograms. This means that it has the capability to lift and transport objects weighing up to 5 kilograms.
