Answer:
ANGLE is 35.3 degree celcius
Explanation:
Given data:
mass m and 3m
initial speed Vi
particle with mass m is moving toward left while particle with mass 3m is moving toward right
By using conservation of momentum :
conservation of energy :
After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,
x direction :
y direction :
subsitute these value in energy conservation
35.3 degree from x-axis
Answer:
eight
Explanation:
it's atomic number is 8 which mean that an oxygen atom has eight protons in it's nucleus
A. 4x the force is the correct answer
Answer:8.68 m/s
Explanation:
Given
If the height of vault is h=4.85 m
her center of mass is 1 m above ground
Net height h=3.85 m
conserving energy
Kinetic Energy=gain in Potential Energy
Answer:
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
