Answer:
it means the altitude of the object is 5m high or wide
Answer:
ummm cam you make the question simpler please
Answer:
The amount of heat flow is . How does heat flow through solids? Conduction is the transfer of heat through solids. Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material.
Explanation:
Answer: d = st
Explanation:
We know that the distance is equal to the rate (speed) times the time
d = st
Electromagnetic spectrum is the collection of electromagnetic waves arranged from low frequency electromagnetic waves to high frequency electromagnetic waves.
Electromagnetic waves are produced by electric charge that are accelerating. When a magnetic field combines with electric field electromagnetic waves are produced. The electric field and magnetic wave are perpendicular to one another in electromagnetic waves.
Below are the type of electromagnetic waves in electromagnetic spectrum: (from high frequency ---> low frequency)
Gamma rays - it is in the end of the electromagnetic spectrum, with highest frequency but shortest wavelength. Gamma rays are generated by radioactive substances.
X-rays - it is next to Gamma rays with respect to frequency but has longer wavelength. This wavelength can penetrate metal. It was discovered by Wilhelm Conrad Roentgen in 1895.
Ultraviolet - ultraviolet waves or ultraviolet radiation have shorter wavelength compared to visible light. The main source of UV radiation is the sun.
Visible Light- among other electromagnetic waves, this the only electromagnetic wave that is visible to the naked eye. The waves inside the range of visible light are the colors. From red( longest wavelength inside visible light) to violet (shortest wavelength inside visible light).
Infrared - infrared radiation is beyond the red color on the visible length. Bodies on earth radiated infrared radiation.
Hope this helps, good luck.
