They are all elevated land forms.
Answer:
m = 63.7 kg
Explanation:
As we know that when mass connected to the bungee cord stretch the string then the gravitational potential energy of the person will convert into potential energy of the string at the end
now here we know that when person jump from the top and reach at the end then loss in gravitational potential energy is given as
now when it is at the end of the motion stretch in the string will be
now potential energy of string is given as
now by energy conservation we have
Answer:
Explanation:
A body under concurrent forces (concurrent forces are forces with their line of action acting at a point) is said to be in equilibrium if the sum total of the forces acting on the body is zero.
For forces acting on a balance, the sum of upward forces and the downward forced acting on the balance must be equal for the balance to be in equilibrium.
Also the sum of clockwise moment must be equal to the sum of anticlockwise moment acting on the balance.
Moment is the product of force and the perpendicular distance from the force to the pivot.
e = 0.57 is the moon's orbital eccentricity
You may determine the ellipse's eccentric formula by using
e = r a - r p / r a + r p
The distance r a between the moon and its planet is the greatest.
r p=0.27 The shortest distance between the moon and its planet is r a.
Then, e = r a - r p / r a + r p
e is defined as (r a - 0.27 r a) / (r a + 0.27 r a).
e = 0.73r a / 1.27 r a
e = 0.57
The eccentricity of a conic section expresses how much it resembles a circle. Every conic section has this distinctive parameter, and conic sections are only said to be identical if and only if their eccentricities are the same. A conic section's eccentricity is a non-negative real integer that specifically describes its shape. Formally speaking, two conic sections are comparable if and only if their eccentricities match. The eccentricity can be thought of as a measurement of how far a conic section strays from being round.
