Answer:
Distance, d = 99990 meters
Explanation:
It is given that,
Speed of the train, v = 200 km/h = 55.55 m/s
Time taken, t = 1800 s
Let d is the distance covered by the train. We know that the speed of an object is given by total distance covered divided by total time taken. Mathematically, it is given by :
d = 99990 m
So, the distance covered by the train is 99990 meters. Hence, this is the required solution.
Answer: the magnetic wave will travel out of the screen.
Explanation:
Electric field direction is perpendicular to the magnetic field direction. Both are also perpendicular to the direction of the particles.
Using right hand rule to solve this problem,
This pointed finger depicts the electric field direction which the curly fingers depict the direction of the magnetic field. The pointed thumb will depict the direction in which the wave travel. Which is out of the screen.
Answer:
Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
In the first question, the answer would be the statement 'Brody is correct because the wave involves an input of energy'. The hand wave involves an input of energy and this energy is repeated and is carried from one place to another.
For the next question, the answer would be 'it is a transverse wave' because all are transverse waves.
Correct answer choice is :
B) Red, orange, yellow, green, blue, indigo, and violet
Explanation:
A spectral color is a color that is extracted in a natural human by a single wavelength of light in the apparent rainbow, or by a comparatively narrow band of wavelengths, also recognized as monochromatic light. The combination of colors provided when the light is separated by a prism. Spectrum an indexed order of the elements of an radiation or wave. Electromagnetic rainbow the complete wavelength spectrum of electromagnetic waves.
