Explanation:
Newton's second law shows that there is a direct relation ship between force and acceleration . the grater force that is applied on a object of given mass the more the accelerate. for example doubling the force in the object doubles it's acceleration.
Answer:
D; The microscope and magnifying glass block out the light, which allows the naked eye to focus on the object.
Explanation:
This is to prevent chromatic abberation
Answer:
True
Explanation:
Biosphere refer to regions of the earth(sphere) that supports life. It is made up of biotic and abiotic components. Its abiotic components are non-living components that support life and is made up of the lithosphere (the earth crust,mantle) , atmosphere(area of gases and air which is held by gravitational force) and the hydrosphere(all water bodies which includes ocean, sea, lakes, rivers etc).
Answer:
The frequency of the green light is
Explanation:
The visible region is part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of in the vacuum.
Green light is part of the visible region. Therefore, the frequency can be determined by the following equation:
(1)
Where c is the speed of light, is the wavelength and is the frequency.
Notice that since it is electromagnetic radiation, equation 1 can be used. Remember that light propagates in the form of an electromagnetic wave (that is a magnetic field perpendicular to an electric field).
Then, can be isolated from equation 1
(2)
Notice that it is necessary to express the wavelength in units of meters.
⇒
Hence, the frequency of the green light is
