Answer:
The displacement of a body has two components: rigid-body displacement and deformation. A rigid-body displacement consists of a simultaneous translation and rotation of the body without changing its shape or size.

<h3><u>Answer;</u></h3>
Centripetal acceleration = 0.931 m/s²
Centripetal force = = 1.234 × 10^-4 Newtons
<h3><u>Explanation;</u></h3>
Centripetal acceleration is given by the formula v²/r, where r is the radius of the circular path and v is the velocity of a body;
Centripetal acc = 3.2²/11
= 0.931 m/s²
Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.
Centripetal force is given by the formula;
mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;
mass = 33 mg or 1.33 × 10^-6 kg, velocity = 3.20 m/s and r = 11 m
Therefore;
Centripetal force = (1.33 ×10^-6 × 3.1²)/ 11
= 1.234 × 10^-4 Newtons
Answer:
240.59 N
Explanation:
We are given that
Mass per unit length=m/l=
Fundamental frequency,f=146.8 Hz
Tension=T=82.4 N
Mass per unit length=
We have to find the tension.
Velocity,v=
New tension,T'=
Hence, the string should have tension 240.59 N so that its fundamental frequency is 146.8 Hz
A curved line on a position/time graph shows that the speed is changing.
So right there, we know there is acceleration.
