Answer:
False
Explanation:
The force of gravity is not only determined by the mass of the two objects but also the distance.
The law of universal gravitation states the product of the masses is directly proportional to the gravitational force, but it is also indirectly proportional to the square of the distance between them.
In other words, the greater the masses of each the greater the gravitational force, but the greater the distance between the two, the weaker the gravitational force.
7.8 g/cm3 because Mass/Volume=Density
Answer:
PART A: 412.98 nm
PART B: 524.92 nm
Explanation:
The equation below can be used for a diffraction grating of nth order image:
n*λ = d*sinθ
Therefore, for first order images, n = 1 and:
λ = d*sinθ.
The angle θ can be calculated as follow:
tan θ = 9.95 cm/15.0 cm = 0.663 and
θ = (0.663) = 33.56°
Thus: d =λ/sin θ = 461/sin 33.56° = 833.97 nm
PART A:
For a position of 8.55 cm:
tan θ = 8.55 cm/15.0 cm = 0.57 and
θ = (0.57) = 29.68°
Therefore:
λ =d*sin θ = 833.97*sin 29.68° = 412.98 nm
PART B:
For a position of 12.15 cm:
tan θ = 12.15 cm/15.0 cm = 0.81 and
θ = (0.81) = 39.01°
Therefore:
λ =d*sin θ = 833.97*sin 39.01° = 524.92 nm
Answer:
87 (whatever unit its using)
