It’s D the time period within pendulums are constant, distance is always measured with kilometers within cities and basic unit is always seconds.
Answer:
The answer is 80 kN . m (clockwise)
Explanation:
As,
M = P x L
Here, the towline exerts a force is P.
Substituting P for 4000N.
M = -4000N x 20m
= -80000N.m
= 80kN.m
Maximum moment about the point O is 80kN.m (Clockwise)
Answer:
The answer for a classical particle is 0.00595
Explanation:
The equation of the wave function of a particle in a box in the second excited state equals:
ψ(x) = ((2/L)^1/2) * sin((3*pi*x)/L)
The probability is equal to:
P(x)dx = (|ψ(x)|^2)dx = ((2/L)^1/2) * sin((3*pi*x)/L) = (2/L) * sin^2((3*pi*x)/L) dx
for x = 0.166 nm
P(x)dx = (2/0.167) * sin^2((3*pi*0.166)/0.167) * 100 pm = 0.037x10^-3
for x = 0.028 nm
P(x)dx = (2/0.167) * sin^2((3*pi*0.028)/0.167) * 100 pm = 11x10^-3
for x = 0.067 nm
P(x)dx = (2/0.167) * sin^2((3*pi*0.067)/0.167) * 100 pm = 3.99x10^-3
therefore, the classical probability is equal to:
(1/L)dx = (1/0.167)*100 pm = 0.00595
The answer is #3: Oxidation because oxidation is when a substance reacts with oxygen, which causes the substance to rust. When a rock contains iron and that iron comes in contact with oxygen, iron oxide is created; this weakens the rock.
