Answer:
Newton
is the answer of si unit of force
Answer:
The angular acceleration of the top is 0.18 rad/s²
Explanation:
Given;
angular velocity of the top, ω = 16 rad/s
time it takes to come to a complete stop, t = 88.9s
The angular acceleration of the top, is calculated as;
α is the angular acceleration
ω is angular acceleration
t is the time
Therefore, the angular acceleration of the top is 0.18 rad/s²
Kinematics is the branch of Physics that deals with
the mathematical methods of describing motion.
Known values; mass per / volume and mass of each atom
average volume=<span> volume per atom. </span>
<span>density*mass per atom = volume per atom </span>
<span>1cm^3 / 7.87 gram * 9.27 *10^-26 kg /atom* 1000 gram / kg=
</span>=<span>1.178 * 10^-22 cm^3 per atom </span>
<span>Convert that to mass </span>
<span>1 cm^3 * (1 m / 100 cm)^3 </span>
average volume= <span>1.178 *10^-29 m^3 per atom </span>
<span>distance: </span>
<span>Volume of a cube is L^3 </span>
<span>so L = (1.178*10^-29)^(1/3) </span>
<span>Half way through the cube is distance 1/2 L. </span>
<span>Second cube is 1/2 L </span>
<span>So distance between the center of 2 cubes = L </span>
=2.28 *10^-10 m
