The surface area of a cube is:
S = 6l², making l the subject:
l = √(S/6)
While the volume is:
V = l³
If we substitute l to get:
V = (√(S/6))³
√(S/6) = ³√V
S/6 = (³√V)²
S = 6(³√V)² ⇒ 6V^(2/3)
Answer:
Explanation:
Momentum P = Mass x Velocity
M = 4.5kg
V = 7m/s
4.5kg x 7m/s
= 31.5xkgm/s
L=IW( Angular momentum) at stationary origin (0,0)
I = 1/2 x Mr^2
L = 1/2 x 4.5x 31.5
L = 70.8kgm/s
At stationary point, (0,0) No coordinate exist
The answer is w=p.t. Substitution:hz 110.20.
.012 J is going to be your answer
