Answer:
Ok I'm not 100% on this one but, try 3 lifes sorry if u get it wrong D:
Explanation:
D. Increase In Density
This is because more buoyancy an object has, the more it increases in density.
Answer:
Explanation:
Given that
L = 3 m
M = 2.4 kg
m=0.7 kg
r= L/2 = 1.5 m
The moment of inertia of rod about it center
The moment of inertia of point mass about center of rod
I'= mr² + mr²
So total moment of inertia
By putting the values
499.15 is lines per millimeter needed in a diffraction grating if the lines are to be resolved in the second-order spectrum with a beam of width 0.10 mm.
the wave length of the sodium spectrum are λ1 = 589.0 nm and λ2 =589.59 nm
The resolving power of the grating is R = λ/Δλ =Nm.
Thus, the total number of lines needed on the grating to resolve the wavelengths in order m is
For the sodium doublet in the first order, N = λ /m(Δλ)
where λ = 589.0 nm , Δλ = 589.59 nm -589.0 nm = 0.59 nm
m = 2
The minimum number of lines in the grating
N = [589.0 nm] / [(2)( 0.59 nm )] = 499.15

Answer: In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.
