Answer:
The quality of a formed rivet is determined by the geometry from its formation of the river heat, and the extent to which the hole is filled up by the rivet.
Explanation:
The quality of a formed rivet is determined by the geometry from its formation of the river heat, and the extent to which the hole is filled up by the rivet. This helps determine the squeeze force, rivet length, rivet diameter tolerance, hole countersunk depth and hole diameter tolerance, plays a big role on the quality of rivet formed. When the tolerance of the hole it’s placed is smaller the grip from the river is stronger unlike when it’s loose.
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:
i think it might be c but i know its not A or B and im
on the fence for D so the best answer would be C
Explanation:
Answer:
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
39929.4542466 m
Explanation:
Total mass of the asteroids

= Mass of Earth = 
The ratio is

The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
Volume is given by

The diameter is 39929.4542466 m
Kinetic energy since if its rolling is already using the stored potential energy that it had before it was given an amount of energy to release it for a given time
