Answer:
Explanation:
Given that,
Efficiency of heat engine,
Temperature of hot source,
We need to find the temperature of cold sink i.e. . The efficiency of heat engine is given by :
So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
Explanation:
The somatic nervous system coordinates the voluntary control of movement in the body system.
The nervous system is made up of the central nervous system and peripheral nervous system.

Answer:
A. an increase in the height of the sound wave
Explanation:
Volume of the sound is measured by its intensity
So here we know that
intensity is directly depends on the square of the amplitude of the sound wave
so here as intensity depends on the loudness of the sound given as
so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase
So correct answer will be
A. an increase in the height of the sound wave
Use the dot product.
(a•b)=(2x3)+(-8x-4)+(1x-12)
=26
