<span>Displacement is identified as the net movement of a thing with detail to its initial location. One may journey out of his city and come back. Notwithstanding having enclosed many miles, he will have a displacement of 0. This is true for all trails that have zero displacement that they all go back to their initial position.</span>
The heat transferred is -30J
When the gas undergoes compression, work is done on the gas and its internal energy increases.
According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW

The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.
Therefore, the heat given to the gas is given by,

Thus, an amount of heat equal to 30 J flows out of the system.
Answer:
BA
0

Explanation:
B = Magnetic field
A = Area
= Angle
t = Time taken
Before rotation the magnetic flux is given by

Magnetic flux is BA
After rotation the magnetic flux is given by

The magnetic flux is 0
Magnitude of emf is given by

The magnitude of the average emf induced in the entire coil is 
Hello,
I'd be glad to help.
Momentum = (mass) times (speed)
= (75 kg) x (18 m/s)
= 1,350 kg-m/s .
Hope this helps
Answer:
the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.
Explanation:
This problem asks that we determine whether or not a critical flaw in a wide plate is subject to detection given the limit of the flaw detection apparatus (3.0 mm), the value of KIc (98.9 MPa m), the design stress (sy/2 in which s y = 860 MPa), and Y = 1.0.

Therefore, the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.
