Answer: Both masses are 0.285 m apart
Explanation:
According to the law of Universal Gravitation:
Where:
is the gravitational force between the masses
is the gravitational constant
is the mass of the first object
is the mass of the second object
is the distance between the objects
Isolating :
This is the distance between both objects
Answer:
Explanation:
a ) Refractive index (μ ) = Sin i / Sin r
i is angle of incidence = 30.2 and r is angle of refraction = 18.5 degree
μ = Sin 30.2 / sin 18.5 = 0.5030 / .3173 = 1.585.
b ) Wave length in a medium = wavelength in air / refractive index
= 632.8 / 1.585 = 399.24 nm.
c ) frequency in solution = frequency in vacuum
=
= 47 x 10¹³ Hz
d ) Speed in the solution = Speed in vacuum / Refractive index
=
= 1.893 x 10⁸ ms⁻¹.
Answer:
say a lighter car is going 80mph and a heavier car is going the same speed who do you think will have more damage i will say the heavier car
Explanation:
Answer:
Explanation:
Let the amplitude of individual wave be I and resultant amplitude be 1.703 I . Let the phase difference be Ф in terms of degree
From the formula of resultant vector
(1.703I)² = I² + I² + 2 I² cosФ
2.9 I² = 2I² + 2 I² cosФ
.9I² = 2 I² cosФ
cosФ = .9 / 2
= .45
Ф = 63.25 .
