Answer:
-50.22kJ
Explanation:
Given:
Initial state Temperature =300k
Pressure 1= 150kPa
Pressure 2 = 800kPa
Volume 1 = 0.2m^3
Work done = Pressure 1 × Volume 1 × (inverse of pressure 1 ÷ pressure 2)
= 150kPa × 0.2m^3 × (inv 150 kPa ÷800 kPa)
= - 50.22kJ
Answer:
Explanation:
Given
charge is placed at
another charge of is at
We know that Electric field due to positive charge is away from it and Electric field due to negative charge is towards it.
so net electric field is zero somewhere beyond negatively charged particle
Electric Field due to at some distance r from it
Now Electric Field due to is
Now
thus
Thus Electric field is zero at some distance r=1.43 cm right of
Answer: True
Explanation: The process in sheet metal which separates the metal sheet in straight line by cutting is known as shearing operation.The process of shearing is carried out by application of shearing forces on the metal sheet. this operation separates the metal sheet into two parts by the edges. They have the certain limited tolerance. Therefore the given statement in the question is true.
