Answer:
Acceleration of the bullet will be 1778835.6
Explanation:
We have given length of the barrel refile s= 0.855 m
When the bullet leaves the muzzle its velocity is 553 m/sec
So final velocity v = 553 m/sec
Initial velocity will be 0 that is u = 0 m/sec
According to third equation of motion 


Im not sure how detailed your answer is supposed to be but here it is: The particle that vibrates contains energy. That exact amount of energy is passed on to the next particle. This occurs because as you must know, energy is neither created nor destroyed. The same amount of energy contained in the vibration is simply passed on.
Answer:
7.45
Explanation:
At 3.0 m PE = m*g*3.0, KE = m*g*(4.0 - 3.0)
At 2.0 m PE = m*g*2.0, KE = m*g*(4.0 - 2.0)
At 3.0 m PE = m*g*1.0, KE = m*g*(4.0 - 1.0)
At 0 m PE = 0, KE = m*g*h = total energy = 7.45 J
In a completely inelastic collision, the two objects stick together after the collision.
Continuing education opportunities allow adults to improve their skills, complete their education and also to change careers.
Answer: Option D
<u>Explanation:
</u>
As we continue our education for higher studies we can learn new things. We can improve our skills by going for higher studies. Some people have a break in their education and they can also continue their education after sometime to complete their course.
So, it helps them to cater their needs and enhance their knowledge. Also when we go for higher studies, we get to know other things about the subject and can try for different career choices. Also, we can even change our ongoing career if we go for higher education and find some other career more interesting and profitable than the existing ones.
