True.
Conductivity is the ability to transmit heat, electricity or sound. Conductivity is a physical property.
A physical property is one which can be measured or observed without changing the composition or identity of a the substance.
Conductivity is a physical property because the composition of the substance does not change.
A copper wire is still a copper wire when it is conducting electricity. Like wise, an aluminum rod is still an aluminum rod when heated. It is conducting heat but the heat does not change it, it is still an aluminum rod during the whole process.

The new speed of the aircraft is equal to 774.61 mph north of east.
Why?
To calculate the new speed, we first need to know the horizontal component of the wind's speed (moving to the east) since the jet is moving to the east.
We can use the following formulas to solve the problem:
We are given the following information:
So, substituting and calculating we have:
For the vertical speed, we have:
Now, to calculate the airplane speed , we can use the following equation (Pytagorean Theorem):
Hence, we have that the new speed is equal to 774.61 mph north of east.
Have a nice day!
