Answer:
Angular acceleration will be 
Explanation:
We have given initial angular speed of a particular disk 
And it finally comes to rest so final angular speed 
Time is given as t = 0.569 sec
From third equation of motion we know that
So angular acceleration 
Answer:
The method used to find atomic mass depends on whether you're looking at a single atom, a natural sample, or a sample containing a known ratio of isotopes:
Look Up Atomic Mass on the Periodic Table If it's your first encounter with chemistry, your instructor will want you...
Sum of Protons and Neutrons for a Single Atom To calculate the atomic mass of a single
Answer is B. both potential and kinetic energy.
Answer:
option A
Explanation:
The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.
Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.
We will see comet shower when we earth will cross the orbit of the comet.
Hence, the correct answer is option A
F = mass × acceleration
17 = mass × 5
mass = 17/5
