The atom contains three kinds of particles:
- <u>Electrons</u>: They are negative charged particles with charge of 1.6× C and they spin around the nucleus in specific orbits
- <u>Protons</u>: They are positive charged particles with the same charge of the electrons (but in positive sign) and they are located inside the nucleus
- <u>Neutrons</u>: They are uncharged particles and they are located inside the nucleus with the protons
Then the atom contains positive particles and negative particles, it is electrically neutral.
The correct answer is D. Newton
It stays the same. Boiling point does not change when you change the height.
I hope i have helped you!
Answer:
Explanation:
Length of small intestine = 6 m
force applied = .14 N
Work done = force x displacement
= .14 x 6
= 9.6 J
Answer: The momentum of the system after the collision is 0.2 kg m/s.
Explanation:
According to the conservation of momentum, the total momentum of the system before the collision is same the total momentum of the system after the collision in an isolated system.
Here, m_{1},m_{2} are the first and second object, v_{1},v_{2} are the initial velocities of the first and second objects and u_{1},u_{2} are the final velocities of the first and the second objects.
Use the formula of the conservation of the momentum.
Put m_{1}=0.6 kg, m_{2}=0.5 kg, v_{1}=0.5 m/s and v_{2}=-0.2 m/s.
= 0.2 kg m/s[/tex]
Therefore, the momentum of the system after the collision is 0.2 kg m/s.
