Answer:
by getting a good machine
Answer:
a)Bulk deformation process
Explanation:
<u>Rolling</u>
Rolling is a metal forming process.In rolling work piece passes through two moving rollers and get compressed.in rolling thickness of work piece will reduces and length of work piece will increase for maintaining the constant area.Due to compression bulk deformation takes place.
<u>Shearing</u>
In shearing one surface slides on another surface and deformation take place.shearing is a machining process.This is also a bilk motion deformation process.
So from above we can say that option a is right.
Answer:
Molar mass -56.0774 g/mol
There is a way to calculate this
atomic number for calcium is 20
atomic number for oxygen is 8
The molar mass for calcium is 40
The molar mass for oxygen is 16
CALCIUM OXIDE
40. +. 16
=56g/mol
1 molecule = 1×56=56g/mol
2 molecules=2×56 =112g/mol
Answer:2058.992KJ
Explanation:
Given data
Mass of object
=521kg
initial velocity
=90m/s
Final velocity
=14m/s
kinetic energy of body is given by=


change in kinectic energy is given by substracting final kinetic energy from initial kinetic energy of body.
Change in kinetic energy=

Change in kinetic energy=

Change in kinetic energy=2058.992KJ
