First, find the components of
vector C (I don't know how you added the vector arrow but that's pretty cool).
Ax + Bx = Cx, Ay + By = Cy
5 + -3 = 2, 2 + -5 = -3
Vector C can be represented as 2x, -3y.
Next, using a trigonometric function tangent you may find the angle from the origin

= arctan(-3/2)

°

rad
Answer: 800
Explanation:
1/2 x m x v^2 = m x g x h
KE = 10 x 10 x 8
KE= 800
To find the solution to the problem, we would be using Planck's equation which is E = hv
Where:
E = energy
h = Planck's constant = 6.626 x 10-34 J·s
ν = frequency
Then, you’ll need a second equation which is c = λν
Where:
c = speed of light = 3 x 108 m/sec
λ = wavelength
ν = frequency
Reorder the equation to solve for frequency:ν = c/λ
Next, substitute frequency in the first equation with c/λ to get a formula you can use:
E = hν
E = hc/λ
But we are looking for the wavelength, so rearrange it more, then our final equation would be:
λ = hc / E
λ = (6.625E-34)(3.0E8 m/s) / (1.06E-13)
λ = 1.875E-12 m
Answer:
v = 3.78 m/s
Explanation:
given,
mass of the child = 36 Kg
length of the chain, r = 2.9 m
tension in each chain, T = 265 N
now,
Net force acting in the system
2 T - m g = m a
T is the tension in the chain
a is the acceleration in the normal direction
here, 
now,


v² = 14.274
v = 3.78 m/s
speed of the child at the lowest point is equal to 3.78 m/s
The right answer for the question that is being asked and shown above is that: "B. condensation from the ocean and then evaporation into a cloud." a water molecule transfer from the ocean to form part of a cloud in the atmosphere is that <span>condensation from the ocean and then evaporation into a cloud</span>
