No, electrical conductors are not necessary for the electrical transmission between the recipient and the source. Through a vacuum, sunlight carries electromagnetic energy to Earth.
What is meant by the transmission of electric energy?
- Electrical transmission refers to the process of transferring produced power to the transmission network situated in populous regions, typically across large distances. Transformers, which raise voltage levels to enable long-distance transmission, is a crucial component of this process.
- Electric power can be transported primarily via one of two systems: the electrical transmission method for high voltage DC electrical transmission method for high AC.
Therefore it is concluded that theelectrical transmission does not need any conductor.

Answer:
Explanation:
Given:
- angle of launch of projectile from horizontal,
- range of projectile,
<u>We have formula for the range of projectile:</u>
putting the respective values
is the velocity with which Tom should jump to land on the other roof.
Average speed of the car is 4.57 m/s
Explanation:
- Speed is calculated by the rate of change of displacement.
- It is given by the formula, Speed = Distance/Time
- Here, distance = 112 m and time = 24.5 s
Speed of the car = 112/24.5 = 4.57 m/s
Answer:
option A
Explanation:
A soccer field is about 100 meters of length, with the other instruments is possible to make the measure, but it will be very complex and it will take time. Therefore with the 50-m tape, the student will need only two measures.
