Dispersion occurs due to the different degrees of refraction experienced by different colours of light. Light of different colours may travel with the same speed in a vacuum, but they travel at different speeds in some refracting medium. The speed of violet light is relatively lower than that of red light.
Answer:
<h2>Lines of Force around an Electromagnet</h2>
Explanation:
<h3>The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field</h3>
Well other planets have a gravitational pull that's what keep the planet's orbiting the sun. But the amount of gravity differs by mass.
Hope this helps :)
I believe the answer is D. <span> More sunlight is trapped by the atmosphere to cause global warming.
Even though Atmosphere usually contains Co2, the amount is really minor and heat from the Sunlight usually still able to reflected outside under noermal circumtances. But, due to usage of fossil fuels, the amount of CO2 in the atmosphere is significantly increased and making the sunlight unable to reflected outside and trapped within the Earth.</span>
The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
