Answer:
Well sports back then were diffrent for example football was soccer and soccer was not even a word!!! They had diffrent rules too. HOPE THIS HELPS GOOD LUCK!!!!!
Explanation:
Lets do the sum of the forces about the elbow joint.
Fm = Force of Muscle; Fe = Force Elbow; Fb = Force Ball
Sum Force about Joint = (-2.5)Fm + 12.5Fe + 30Fb = 0
(-2.5)Fm + 12.5(2.8) + 30(6.9) = 0
Fm = 96.8kg
Fm = 96.8 * 9.8 = 948.6N
Do you understand why the -2.5 is negative?
<span>
Because I put the origin at the joint. So when you go left it is negative and when you go right it is positive. </span>
Explanation:
what is the difference between cytology and histology
Histology involves the study of tissue and Cytology involves the study of cells, both of which are derived from various organs of the human body. The Histology laboratory is responsible for the preparation of tissue for diagnosis by Pathologists.
Answer: The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system.
Explanation:
Answer:
a. 572Btu/s
b.0.1483Btu/s.R
Explanation:
a.Assume a steady state operation, KE and PE are both neglected and fluids properties are constant.
From table A-3E, the specific heat of water is 
, and the steam properties as, A-4E:
Using the energy balance for the system:
Hence, the rate of heat transfer in the heat exchanger is 572Btu/s
b. Heat gained by the water is equal to the heat lost by the condensing steam.
-The rate of steam condensation is expressed as:
Entropy generation in the heat exchanger could be defined using the entropy balance on the system:
Hence,the rate of entropy generation in the heat exchanger. is 0.1483Btu/s.R
