The correct answer is a
Explanation:
The concept of center of mass strongly simplifies the analysis of problems, since all the external bridging forces = denote the point of the center ce plus.
xcm = 1 / M ∑xi mi
v cm = 1 / M ∑ xi vi
When we do this, the momentum and the kinetic energy are conserved, that is, it is equivalent to the movement of the particle system
The correct answer is a
In regard to career, both Patricia and Pharaoh are in a state of identity Moratorium. This state of identity crisis leads them to explore their identity and values. However, they haven't committed yet but they are experimenting, Patricia tried a a variety of entry-level classes, while Pharaoh researched many areas of study until he can decide.
identity Moratorium is characterized by low commitment
and high exploration.
Answer:
Explanation:
Energy of system of charges
= k q₁q₂ / r₁₂ + k q₁q₃ / r₁₃ + k q₃q₂ / r₃₂
q₁ , q₂ and q₃ are charges and r₁₂ , r₁₃ , r₃₂ are densities between them
9 x 10⁹ ( 2x2 x10⁻¹²/ .25 + 2x2 x10⁻¹²/ .25 + 2x2 x10⁻¹²/ .25 )
= 9 x 10⁹ x 3 x 16 x 10⁻¹²
= 432 x 10⁻³
= .432 J .
Answer:
Explanation:
As we know that car is moving in the curve of given radius
So the force on that car is given as
So for the first car we have
for other car we will have
now we will have
