How do local action make the cell defective​

Physics
1 answer:
docker41 [41]3 years ago
7 0
Local action: local action is one such defect. The local action is the discharge of current by a battery even when it is not connected to an external power device due to the impurities present. Then when cell is not use, electric currents flow through these electrodes. Eventually resulting in the determination of the cell.

Say you want to make a sling by swinging a mass M of 2.3 kg in a horizontal circle of radius 0.034 m, using a string of length 0
ycow [4]

Answer:

T = 764.41 N

Explanation:

In this case the tension of the string is determined by the centripetal force. The formula to calculate the centripetal force is given by:

F_c=m\frac{v^2}{r}  (1)

m: mass object = 2.3 kg

r: radius of the circular orbit = 0.034 m

v: tangential speed of the object

However, it is necessary to calculate the velocity v first. To find v you use the formula for the kinetic energy:

K=\frac{1}{2}mv^2

You have the value of the kinetic energy (13.0 J), then, you replace the values of K and m, and solve for v^2:

v^2=\frac{2K}{m}=\frac{2(13.0J)}{2.3kg}=11.3\frac{m^2}{s^2}

you replace this value of v in the equation (1). Also, you replace the values of r and m:

F_c=(2.3kg)(\frac{11.3m^2/s^2}{0.034})=764.41N

hence, the tension in the string must be T =  Fc = 764.41 N

A mule pulls a cart of milk 10 meters with a force of 50 Newton's.Calculate the work done by a mule
san4es73 [151]

Work = Force x Distance

Assuming that this work is being done parallel to the displacement that is, but under that assumption:

W = (50)(10)

W = 500 J

Describe an application where a parallel circuit might work better than a series circuit
babunello [35]
In rooms where there are multiple lights, a parallel circuit is better.

In a series circuit, if one light broke, all of the lights would turn off, as the circuit would be broken.

However, in parallel, if one bulb broke, the circuit could still be complete through the other bulbs, so they will stay on.

Would the solar panel work under a fluorescent or halogen light? explain your response being sure to relate your observations to
eduard

I think that the solar panel would work under a fluorescent or halogen light if the photons are being produced. These types of lights mimic sunlight so it would not work as good as the real thing but it could work. Just not be as powerful.

A wave has a wavelength of 7 mm and a frequency of 19 hertz. What is its speed?
ASHA 777 [7]

Speed = (frequency) x (wavelength)

Speed = (19 per second) x (7 mm)

Speed = (19 x 7) (per second · mm)

<em>Speed = 133 mm/sec</em>

or you might want to write  <em>Speed = 0.133 m/s</em> .
