Answer:
If your mass on Earth is 71 Kg, what is your weight on Earth to two decimal places?
your mother you uncultured swain how dumb can you be go jump off a bridge ETAY who even names there child ETAY more like EBAY
Answer:
(a) Force and Pressure
Explanation:
Acc to the formula,
Force = Pressure/Area
Therefore it depends on force and pressure
The correct answer is
A concave lens diverges light and curves inward.
A picture of a concave lens and the ray diagram produced by it can be seen in attachment. As it can observed, the concave lens (also called diverging lens) is wider at the edges and narrow at the centre (so, it curves inward), and it can also be seen that the lens diverges the incoming light rays.
Mass is an independent quantity. It can neither be created nor be destroyed. So mass of giraffe will not change on moon.
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.
