Answer:
decreases by 1/9
Explanation:
the equation of kinetic energy is
here, we see that Kinetic Energy and v (velocity) are on opposide sides of the equation, this means that they are directly proportional (when one increases, the other one must increase (assuming mass (m) is constant)): KE∝
since V is decreasing by factor of 1/3, simply plug it in for v^2 to get (1/3)^2,
this equals (1/9). So KE will become 1/9 of original value
Answer:
Explanation:
Two previously undeformed cylindrical specimens of an alloy are to be strain hardened by reducing their cross-sectional areas (while maintaining their circular cross sections). For one specimen, the initial and deformed radii are 15 mm and 12 mm, respectively. The second specimen, with an initial radius of 11 mm, must have the same deformed hardness as the first specimen.Compute the second specimen's radius after deformation.
The percentage of cold work to be done to deform the two cylindrical is calculated
we input the values
We can now calculate the deformed radius of the second specimen for the same deformation
Answer:
Science is what makes up the wires, engineering is how that all works, technology is what the goal is, and math is how many of a component you have to put in it.
Explanation:
I am in an engineering class
Answer:
It could affect how far the projectile travels
Explanation:
Facing Uphill: Moves less far
Downhill: Moves further
