Answer:
Continuous
Explanation:
A circuit can only light up a lightbulb if there is a continuous path for electricity to travel from one end of the energy source to the other end.
Answer:
Shaft
coiled
generators
Kinetic
Electrical
Explanation:
By using moving shaft and coiled wire together, electric generators create electricity. Electric generators essentially convert kinetic energy (the energy of motion) into electric energy.

Answer:
The maximum detection range is 39.75 km
Explanation:
Given that;
Antenna height h1 = 40 m
Target height ( patrol boat mast ) h2 = 11 m
Using RADAR, what is the maximum detection range = ?
Using RADAR
we know that; Maximum detection range = (√17h1 + √17h2) km
where h1 and h2 are heights of the antenna and target height in meters
so we substitute in our values
Maximum detection range = (√(17 × 40) + √(17 × 11)) km
Maximum detection range = (√680 + √187) km
Maximum detection range = (26.0768 + 13.6747) km
Maximum detection range = (26.0768 + 13.6747) km
Maximum detection range = 39.75 km
Therefore, The maximum detection range is 39.75 km
Answer:
from vacuum to air
Explanation:
Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.
- When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
- Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.
The correct option must be from a less dense medium to a denser medium.
density of glass = 2500 kg/m³
density of air = 1.275 kg/m³
density of ice = 919 kg/m³
density of water = 1000 kg/m³
density of plastic = 940 kg/m³
density of vacuum = 6.5 x 10⁻²⁷ kg/m³
The two possible options are;
from ice to water
from vacuum to air
The difference in densities of ice and water is not larger compared to vacuum and air.
If you are required to choose two options, the two options are correct
But if it is only one option, then from vacuum to air is the correct answer.
Therefore, the correct option is from vacuum to air
