I believe Action potential is the brief wave of positive charge that sweeps down the axon. Axon is part of the neuron that conducts impulses from the dendrites towards the cell body along the neuron. The action potential is brief since the sodium channels can only stay open for a very brief amount of time. As it travels along the neuron there is a change in polarity across the membrane of the axon .
You are given a fixed rate of 15.9 cm³/s. You are also given with the amount of volume in 237 cm³. Through the approach of dimensional analysis, you can manipulate through operations such that the end result of the units must be in seconds. The solution is as follows:
237 cm³ * (1 s/15.9 cm³) = 14.9 seconds
Responder:
20πrads ^ -1; 24πrads ^ -1; 0,1 seg; 10 Hz
Explicación:
Dado lo siguiente:
Radio (r) del círculo = 120 cm
600 revoluciones por minuto en radianes por segundo
(600 / min) * (2π rad / 1 rev) * (1min / 60seg)
(1200πrad / 60sec) = 20π rad ^ -1
Velocidad angular (w) = 20πrads ^ -1
Velocidad lineal = radio (r) * velocidad angular (w)
Velocidad lineal = (120/100) * 20πrad
Velocidad lineal = 1.2 * 20πrads ^ -1 = 24πrads ^ -1
C.) Período (T):
T = 2π / w = 2π / 20π = 0.1 seg
D.) Frecuencia (f):
f = 1 / T = 1 / 0.1
1 / 0,1 = 10 Hz
Answer: c) 42 N
Explanation:
M = 2.5 kg
L = 2.5 m
h = L(1 - sin 40 degrees)
Potential energy Mgh = MgL(1 - sin 40 degrees )
kinetic energy = MgL(1 - sin 40 degrees)
(1/2)Mv^2 = MgL(1 - sin 40 deg)
Mv^2 = 2MgL(1 - sin 40 deg)
Fc = Mv^2/L
Fc = 2Mg(1 - sin 40 deg)
= 2 x 2.5 x 9.8 x (1 - sin 40 deg)
Fc = 17.5 N
Let T = tension in the string.
T - Mg = Fc
T - 2.5 x 9.8 = 17.5
T - 24.5 = 17.5
T = 17.5 + 24.5
T = 42 N
