Well water or any liquid actually takes the form of the cup of bowl or whatever you put the liquid in
REMEMBER- Liquid has no shape.
hope this helps!!!!!!!!
Answer:
Explanation:
Given:
A = 589 J
D = 1 100 m
____________
F - ?
A = F·D
F = A / D = 589 / 1100 ≈ 0.54 N
PE = (weight) x (height)
= (mass) x (gravity) x (height)
= (410 kg) x (9.8 m/s²) x (12 m)
= (410 x 9.8 x 12) kg-m²/s²
= 48,210 joules (rounded)
Answer:
v = 0.22 c and wavelength is decrease so galaxy A is move away from stationary galaxy
v = 0.095 c and wavelength is increase so galaxy B come toward stationary galaxy
Explanation:
Given data
found = 500 nm
shifted A = 400 nm
shifted B = 550 nm
to find out
How fast and in what direction is galaxy
solution
we use here formula that is
(λ) shifted = √(1-β / 1+β) (λ)found
1-β / 1+β = (4/5)² ..................1
1-β / 1+β = 16 / 25
β = 0.22
v/c = 0.22
v = 0.22 c
here wavelength is decrease so galaxy A is move away from stationary galaxy
and
here according to equation 1
and we use shifted 550 nm
so
1-β / 1+β = (5.5/5)²
1-β / 1+β = 30.25 / 25
β = 0.095
so v/c = 0.095
v = 0.095 c
here wavelength is increase so galaxy B come toward stationary galaxy
