Answer:
Time=8.23880597 seconds 
Explanation:
Quantity of charge(q)=2.76c
Current(I)=0.335A
Time(t)=?
t=q/I
t=2.76/0.335
t=8.23880597seconds
 
        
             
        
        
        
Answer:
work done is -150 kJ 
Explanation:
given data 
volume v1 = 2 m³
pressure p1 = 100 kPa
pressure p2 = 200 kPa
internal energy = 10 kJ 
heat is transferred  = 150 kJ
solution 
we know from 1st law of thermodynamic is 
Q = du +W    ............1 
put here value and we get 
-140 = 10 + W 
W = -150 kJ 
as here work done is -ve so we can say work is being done on system

<span>The correct answer is: Oxygen
Explanation:
In order to function properly (movement etc.) during exercise, muscles require oxygen. During exercise, the depth as well as the rate of breathing increase, which in turn increases the amount of oxygen inhaled. In order to expand and contract lungs and for other bodily movements, muscles require oxygen, and for that, more oxygen is carried in the blood to muscles. Hence, the correct answer is Oxygen.</span>
        
                    
             
        
        
        
<span>(a) 0.0676 l
(b) 67.6 cc
So we've been told that 5.00 L of blood flows through the heart every minute and that the heart beats 74.0 times per minute. So that means that for every beat of the heart, 5.00 L / 74.0 = 0.067567568 L of blood flows through the heart. Rounding to 3 significant figures gives 0.0676 l. Converting from liters to cubic centimeters simply require a multiplication by 1000, so we have 67.6 cc of blood pumped per beat.</span>
