A ravine is a smaller version of a canyon that is typically formed by stream bank erosion. Ravines are greater in scale than gullies, but smaller than valleys.
<h3>What is ravine?</h3>
A ravine is a slope landform with relatively steep sides,Ravines may or may not contain active streams running along the down slope channel that produced them.
Ravine are frequently characterized by intermittent streams, since their geographic size is too small to maintain a perennial watercourse.
Hence, a ravine is a smaller version of a canyon that is typically formed by stream bank erosion.

Answer:
0.002699 m or 2.699 mm
Explanation:
y = Fringe distance
d= Distance between slits = 0.310mm
L = Screen distance = 4.40m
λ= Wavelength
Given from question
λ₁= 660 nm = 6.6 x 10^-9 m
λ₂= 470 nm = 4.7 x 10^-9 m
d = 0.340 mm = 3.4 x 10^-3 m
L = 4.40 m
In the case of constructive interference, we use below formula
y/L = mλ/d
For first order wavelength
(y₁/4.40) =(1×660x10⁻⁹)/(0.310*10⁻³)
y₁= (0.310*10⁻³)×(4.40)/(0.310*10⁻³)
y₁=0.00937m
(y2/4.40) =(1×470x10⁻⁹)/(0.310*10⁻³)
y2= =(1×470x10⁻⁹)×(4.40)/(0.310*10⁻³)
y2=0.00667m
distance between the fringes is given by (y₁ -y2)
=0.00937-0.00667=0.002699m
Therefore, distance on the screen between the first-order bright fringes for the two wavelengths is 0.002699 m or 2.699 mm
We start by describing that phase transition is most commonly used to describe the change between solid, liquid and gaseous states of matter, including plasma for particular cases. When the transitional state between two substances is reached, the temperature change becomes null until there is the exchange required for the union or disunity of the atoms. The thermal energy supplied or eliminated is equal to the binding energy between atoms.
There is no change in chemical composition unless a combustion state is reached. But that is not related to the phase transition. The molecules are not altered either because that would alter the composition and in the phase change the temperature in this state has no change.
Therefore the correct answer is B.
Silver is classified as a <span>precious metal.
Where Gold is classified as </span><span>transition metal.
Silver has about 47 protons and Gold has way more- about 79 protons.</span>
Answer:
The angle to start the motion is 10.61°.
Compression in the spring=0.18 ft
Explanation:
Given that
coefficient of friction on block (μ)A=0.15
coefficient of friction on block(μ) B=0.25
mass of block A=10 lb
mass of block B=6 lb
Condition for begin the motion of blocks
If the component of gravity along incline plan will more than the friction force between surfaces than blocks will start to move.We know that friction will act opposite to the direction of motion so when blocks will move downward friction will act in opposite direction .
For block A
mg sinα =μmg cosα+F (F=2 x,x is the compression in the spring)
Where F is the spring force
Now by putting the values
[tex]10sinα=0.15(10)cosα+F
10 sinα=1.5 cosα+F--------1
For block B
mg sinα+F =μmg cosα
Now by putting the values
6 sinα+F=0.25 (6)cosα
6 sinα+F=1.5cosα------2
From equation 1 and 2
16 sinα=3 cosα
So α=10.61°
So the angle to start the motion is 10.61°.
Now putting the value of α any of equation to find spring compression
10 sinα=1.5 cosα+F
F=0.36 lb
0.36 lb=2 x
So compression in the spring=0.18 ft
