Answer:
The phase difference between waves 31.7 rad
Explanation:
Given :
Wavelength 
m
Separation between two slit 
m
Angle 
25°
From the formula of phase difference,
Where 
phase difference
rad
Therefore, the phase difference between waves 31.7 rad
The beam is acting as the pivot and the weight of the deck acts through its center its gravity, at the midpoint of the deck.
Center of gravity at: (16 + 4)/2 = 10 ft
Converting 4 ft to meters: 1.22 m
Converting 10 ft to meters: 3.05
F x 1.22 = 3.05 x 3000 x 9.81
F = 73,600 N
The molecules give off heat.
Explanation:
Impulse is the change in momentum. It is also equal to the average force times the change in time.
J = Δp
F Δt = m Δv
The change in momentum is a fixed number; your mass, initial velocity, and final velocity are constant.
F Δt = k
So force and time are inversely proportional. What this means is, we can either have a large force over a short period of time, or a small force over a long period of time.
Obviously, we want a small force over a long period of time. Without airbags, your head would hit the steering wheel very quickly. With airbags, your head has time to decelerate, so there's less force.
Answer:
x=6.19m
Explanation:
Let m1, m2 be the two masses
and x the distance moved by mass 65kg
Therefore:- distance two=10-x
