Answer:
Final speed of the box after it has moved to x = 10 is given as
v = 3.35 m/s
Explanation:
As we know by work energy theorem that work done by all the forces is equal to the change in its kinetic energy
Here work done by external force + work done by friction = change in kinetic energy of the box
so we have
![F x - \mu mg x = \frac{1]{2}mv^2](https://tex.z-dn.net/?f=F%20x%20-%20%5Cmu%20mg%20x%20%3D%20%5Cfrac%7B1%5D%7B2%7Dmv%5E2)
Answer:
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Explanation:
Given;
wavelength = 6.33 x 10^-7 m
Speed of light v = 3.0 x 10^8 m/s.
Frequency of the laser light f
= speed of light/wavelength
Substituting the given values;
f = 3.0 x 10^8 m/s ÷ 6.33 x 10^-7 m
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Myofibrils are composed of long proteins such as actin, myosin, and titin, and other proteins that hold them together. These proteins are organized into thin filaments and thick filaments, which repeat along the length of the myofibril in sections called sarcomeres. Muscles contract by sliding the thin (actin) and thick (myosin) filaments along each other.
