Answer:
2500 J
Explanation:
We can solve the problem by using the first law of thermodynamics:
where
Uf is the final internal energy of the system
Ui is the initial internal energy
Q is the heat added to the system
W is the work done by the system
In this problem, we have:
Q = +1000 J (heat that enters the system)
W = +500 J (work done by the system)
Ui = 2000 J (initial internal energy)
Using these numbers, we can re-arrange the equation to calculate the final internal energy:
circular motion.
cent acc = r omega^2 ... omega is ang vel ... omega=2pi/T ,,,
9.8=rx(2pi/T)^2
if r is known, solve for T
Scurvy and rickets are micronutrient deficiency diseases due to a lack of certain vitamins or minerals in the diet. Scurvy is caused by vitamin C deficiency and rickets by vitamin D.
<h3>What are proteins and carbohydrates?</h3>
- Proteins and carbohydrates are the macronutrient in the body and are sources of energy. Proteins are made of amino acids linked together by the peptide bond and carbohydrates are made of carbon, oxygen, and hydrogen.
- Breathing is a biological process that involves exhalation and inhalation, while respiration is a chemical process that occurs in body cells and tissues.
- The cerebrum and cerebellum are the parts of the brain involved with different functions. The cerebrum of the forebrain is involved with mental, motor, and sensory functions, while the cerebellum is involved with posture, balance, and coordination.
- The infectious disease gets transmitted to another person by viruses, bacteria, fungi, etc., and non-infectious are non-communicable disease that includes age, deficiency, etc.
