Yes everything is made of cells because without cells our being can't stay together.
Answer:
F in the definition of potential energy is the force exerted by the force field, e.g., gravity, spring force, etc. The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position r.
Explanation:
The tension in the string when the ball is at the bottom of the path is 2.61 Newtons.
<h3>Tension</h3>
A tension is simply referred to as a force along the length of a flexible medium such as strings, cable, ropes etc.
Tension in a string revolving can be determined using the expression;
T = mv² / r
Where m is mass of object, v is velocity and r is radius ( length of string )
Given the data in the question;
- Radius ( length of string ) r = 97.7cm = 0.977m
- Tension in the string; T = ?
To determine tension in the string, we substitute our given values into the expression above.
T = mv² / r
T = (0.182kg × (3.74m/s)²) / 0.977m
T = (0.182kg × 13.9876m²/s²) / 0.977m
T = (2.5457432kgm²/s²) / 0.977m
T = 2.61kgm/s²
T = 2.61N
Therefore, the tension in the string when the ball is at the bottom of the path is 2.61 Newtons.

Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and 
is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and 
is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
