What is meant by absolute time? Why was it not noticed before the development of the special theory of relativity?
poizon [28]
<span>Absolute time is placing a number on an object or event. It would be like saying this fossil is 500,000,000 millions years old or a volcanic eruption took place 200,000 years ago. Absolute time is expressed in numbers.
</span>
<span>Newton's assumptions were perfectly rational, considering the prevailing knowledge at the time he lived. His conclusions were absolutely revolutionary, and his work is still used on a daily basis by engineers designing everything from skateboards to spacecraft. </span>

A bicycle has wheels of 0.70 m diameter. The bicyclist accelerates from rest with constant acceleration to 22 km/h in 10.8 s. Wh
Anna11 [10]

Answer:

\alpha=0.16\frac{rad}{s^2}

Explanation:

Angular acceleration is defined as the variation of angular speed with respect to time:

\alpha=\frac{\omega}{t}

The relation between the angular speed and the linear speed is given by:

\omega=\frac{v}{r}

Replacing (2) in (1):

\alpha=\frac{v}{rt}

We need to convert \frac{km}{h} to \frac{m}{s}:

22\frac{km}{h}*\frac{1h}{3600s}*\frac{1000m}{1km}=6.11\frac{m}{s}

Recall that:

r=\frac{d}{2}=\frac{0.7m}{2}=3.5m

Replacing:

\alpha=\frac{6.11\frac{m}{s}}{(3,5m)(10.8s)}\\\alpha=0.16\frac{rad}{s^2}
