<span>The Compound Eye. The arthropod (e.g., insects, crustaceans) eye is built quite differently from the vertebrate eye (and the mollusk eye). Arthropod eyes are called compound eyes because they are made up of repeating units, the ommatidia, each of which functions as a separate visual receptor.</span>
The atom has 71 protons.
(The atomic number of a chemical element is the number of protons found in the nucleus of an atom)
hope this helps
Answer:
list of spring in order of increasing spring constant is given by,
W, Y, X, Z
Explanation:
Spring W:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 20 / 0.5
k = 40 N/m
Spring X:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 60 / 0.3
k = 200 N/m
Spring Y:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 40 / 0.4
k = 100 N/m
Spring Z:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 50 / 0.1
k = 500 N/m
Thus, list of spring in order of increasing spring constant is given by,
W, Y, X, Z
The direction of the angular velocity of the minute hand of a wall-clock is perpendicular to the wall and directed inwards.
The passenger slides away from the centre of the curve.
The angle θ which a cyclist should make with the vertical while taking a circular turn of radius r with velocity v given by
tan θ = v^2/rg
Sharper the curve, smaller is the radius and greater is the value of 0.
The ball dropped of a cliff will have a final velocity of 19.6 m/s at 2s
The free fall formula and the procedure we will use is:
fv = g* t
Where:
- fv = final velocity
- g = acceleration due to gravity
- t = time taken
- h = height traveled
Information of the problem:
- g = 9.8 m/s².
- t = 2 s
- vf = ?
Applying final velocity formula we get:
fv = g* t
fv = 9.8 m/s² * 2 s
fv = 19.6 m/s
<h3>What is free fall?</h3>
It is when the object or mobile falls from a height (h) with a positive acceleration equal to the gravity, describing a vertical rectilinear travel.
