Answer:
94.248 g/sec
Explanation:
For solving the total current of the blood passing first we have to solve the cross sectional area which is given below:
![A_1 = \pi R^2\\\\A_1 = \pi (1)^2\\\\A_1 = 3.1416 cm^2](https://tex.z-dn.net/?f=A_1%20%3D%20%5Cpi%20R%5E2%5C%5C%5C%5CA_1%20%3D%20%5Cpi%20%281%29%5E2%5C%5C%5C%5CA_1%20%3D%203.1416%20cm%5E2)
And, the velocity of blood pumping is 30 cm^2
Now apply the following formula to solve the total current
![Q = \rho A_1V_1\\\\Q = (1)(3.1416)(30)\\\\](https://tex.z-dn.net/?f=Q%20%3D%20%5Crho%20A_1V_1%5C%5C%5C%5CQ%20%3D%20%281%29%283.1416%29%2830%29%5C%5C%5C%5C)
Q = 94.248 g/sec
Basically we applied the above formula So, that the total current could come
Answer:
Conservation of energy
Explanation:
The first law of thermodynamics is given by :
![Q=\Delta U+W](https://tex.z-dn.net/?f=Q%3D%5CDelta%20U%2BW)
Here,
Q is amount of heat added to the system
is change in internal energy
W is amount of work done by the system
It is clear that the energy can be neither created nor destroyed, it remains conserved. Hence, first law of thermodynamics shows that conservation of energy.
Kinetic energy is the energy that is associated with motion. It is the energy possessed by an object that is moving. It is calculated from one-half the product of the mass and the square of the velocity of the object. From this, we can calculate the mass of the object. We do as follows:
KE = mv^2/2
500 J = m(5 m/s)^2 / 2
m = 40 kg

Answer:
B. 12.0A
Explanation:
The circuit shown in the image is a parallel circuit which mean that the voltage of the source is equal across each resistance in the circuit because they are directly connected to the terminals of the voltage source.
The voltage across the 10 Ohms resistor is 120V
So, let's proceed to calculate the current
By using Ohm's Law
![I=\frac{V}{R} \\I= \frac{120.0V}{10.0Ohm} \\I= 12.0A](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BV%7D%7BR%7D%20%5C%5CI%3D%20%5Cfrac%7B120.0V%7D%7B10.0Ohm%7D%20%5C%5CI%3D%2012.0A)
12A is the amount of current flowing through the 10 ohms resistor.
