Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
Sedimentary rocks are formed from the sedimentation and consolidation of sediments
Igneous rocks are formed due to the crystallization of magma.

Hence the correct answer is option (C)

In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. Suppose a circuit board contain

Sergio039 [100]

Answer: 2 diodes

Explanation:

Given : In proof testing of circuit boards, the probability that any particular diode will fail is 0.01.

The number of diodes contained by circuit board = 200

Then , the expected number of diodes to fail is given by :-

$0.01\times200=2$

Therefore, there are 2 diodes that we will expect to fail.

Calculate the change in total internal energy for a system that releases 2.59 × 104 kJ of heat and does 6.46 × 104 kJ of work on

mrs_skeptik [129]

Answer:

See explanation below

Explanation:

The equation to use for this is the following:

dU = q + w

As the heat is being release, this value is negative, and same here happens with the work done, because it's in the surroundings.

Therefore the change in the energy would be:

dU = -2.59x10^4 - 6.46^4

dU = -9.05x10^4 kJ
