Answer:
Explanation:
Given
radius of path 
Velocity of Particle 
where t=time in seconds
angular velocity of particle is given by


And angular acceleration is given by


tangential acceleration is 

Centripetal acceleration 

net acceleration is sum of tangential and centripetal force at any time t is given by



1000 m/s
100m x 10hz=1000m/s
Protons are the representative particles of elements, ionic compounds, and covalent compounds.
The specific heat capacity of different substances vary for the same reason that different substances have different melting and boiling points to one another. If the bonds between atoms are stronger, it will require more energy to heat up the substance.Sep 8, 2018
