A - proximal convoluted tubule
Answer:
8 is c and 9 is b it is shown though the practice as god lol
Answer:
Since it us the resistance that causes the power output, it might be intuitive to think that more resistance produces more power but as P=I^2 * R one actually needs high current and low resistqnce. That means 75 W has lower resistance and higher current.
Now you may think that making the resistance very low, one gets the most power. Not so, as the circuit has wires, power source etc. All the have their resistance. In theory one gets the maximum power over a resistor when the resistor is half of the total resistance of the circuit. This in practice would be inefficient as one would lose half of the total power elsewhere. In practice circuits have fuses that limit the current and one gets the maximum power at the current the fuse is rated to. So if there is 20 A fuse, the maximum power is 2400 W and the corresponding resistance 6 ohm.
Answer:
Presión = 175,97 N/m²
Explanation:
Dados los siguientes datos;
Peso del alumno (fuerza) = 725N
Área de zapatos = 412 cm² a metros cuadrados = 412/100 = 4.12 metros
Para encontrar la presión, usaríamos la siguiente fórmula;
Presión = fuerza / área
Presión = 725 / 4.12
Presión = 175,97 N/m²
Answer:
V = - 2[m/s]
Explanation:
This is a classic problem of relative velocities, in order to solve it we must understand each of the velocities, given in the initial data of the problem.
VA = velocity of passenger A, = 1.5[km/h], it is the same velocity of the sidewalk
VB = 2 + 1.5 = 3.5 [km/h], that is the velocity observed by a person outside from the sidewalk.
And from the perspective of passenger B the speed of passanger A is:
VA-VB = - 2 [m/s]
It means that the passenger B is seen how passenger A is getting close to him and then passed.
