Answer:
Explanation:
distance travelled s = 10 cm
speed v = 1.4 x 10⁶ m /s
v² = u² + 2as
u = 0
v² = 2as
( 1.4 x 10⁶ )² = 2 x a x .10
a = 9.8 x 10¹² m /s²
force on proton = mass x acceleration
= 1.67 x 10⁻²⁷ x 9.8 x 10¹²
= 16.366 x 10⁻¹⁵ N .
If magnitude of electric field be E
force on proton
= E x charge on proton
= E x 1.6 x 10⁻¹⁹
E x 1.6 x 10⁻¹⁹ = 16.366 x 10⁻¹⁵
E = 10.22 x 10⁴ N/C
The direction of electric field will be positive x - direction .
b )
Speed of proton = 1.4 x 10⁶ m /s .
Answer:
Collect more fuel than you think you can use; you may need more than you estimate. Pile fine twigs, grass, or bark shavings loosely as a base.
Answer:
Polarized glasses contains a special filter that block dangerous intensity of lights which are reflected by flat surfaces and they help in reducing glare and discomfort
Explanation:
Sunlight scatters in all the direction. But when this light strikes with the flat surfaces, then the light which is reflected by the flat surface tend to become polarized, means the reflected light will travel in all directions. This reflecting light creates a dangerous intense light that causes glare and reduces visibility.
Polarized glasses contains a special filter that block this type of dangerous intensity lights, help in reducing glare and discomfort.
Therefore, by the above discussion it can be say that the polarized sunglasses particularly effective in reducing glares.
Well, if we are being technical, yes and the only reason I say yes is because the sun is a hot gas rock. And it gives off UV rays which is heat on earth. So, yes. It does
