How do local action make the cell defective​

Physics
1 answer:
docker41 [41]2 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.

A 5.0-kg rock and a 3.0 × 10−4-kg pebble are held near the surface of the earth.(a)Determine the magnitude of the gravitational
a_sh-v [17]

Answer:

a). Determine the magnitude of the gravitational force exerted on each by the earth.

Rock: F = 49.06N

Pebble: F = 29.44N

(b)Calculate the magnitude of the acceleration of each object when released.

Rock: a =9.8m/s^{2}

Pebble:  a =9.8m/s^{2}

Explanation:

The universal law of gravitation is defined as:

F = G\frac{m1m2}{r^{2}}  (1)

Where G is the gravitational constant, m1 and m2 are the masses of the two objects and r is the distance between them.

<em>Case for the rock </em>m = 5.0 Kg<em>:</em>

m1 will be equal to the mass of the Earth m1 = 5.972×10^{24} Kg and since the rock and the pebble are held near the surface of the Earth, then, r will be equal to the radius of the Earth r = 6371000m.

F = (6.67x10^{-11}kg.m/s^{2}.m^{2}/kg^{2})\frac{(5.972x10^{24} Kg)(5.0 Kg)}{(6371000 m)^{2}}

F = 49.06N

Newton's second law can be used to know the acceleration.

F = ma

a =\frac{F}{m} (2)

a =\frac{(49.06 Kg.m/s^{2})}{(5.0 Kg)}

a =9.8m/s^{2}

<em>Case for the pebble </em>m = 3.0 Kg<em>:</em>

F = (6.67x10^{-11}kg.m/s^{2}.m^{2}/kg^{2})\frac{(5.972x10^{24} Kg)(3.0 Kg)}{(6371000 m)^{2}}

F = 29.44N

a =\frac{F}{m}

a =\frac{(29.44 Kg.m/s^{2})}{(3.0 Kg)}

a =9.8m/s^{2}

What the Ph measures??
Elenna [48]
PH measures the concentration of hydrogen ions (H^{+}) in a solution. Knowing this, you can determine how acidic -or basic- your solution is.

During a circus act, a performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of m1 = 7.5
vladimir1956 [14]

Answer:

Explanation:

We shall apply law of conservation of momentum .

total Initial momentum =

7.5 x 8.85 = 66.375 kg m / s

total mass = 7.5 + 61.5 = 69 kg , common velocity of ball and performer be v

Total momentum = 69 v

69 v  = 66.375

v = 66.375 / 69

= .962 m /s .

The material that transmits most light is d) clear glass.

Explanation:

Depending on whether objects can transmit light or not, they can be classified into three types:

  • Opaque: an object opaque does not transmit light at all (light cannot pass through an opaque object). Examples of opaque objects are metals
  • Translucent: translucent objects allow light to pass partially through them. Examples of translucent objects are fluids
  • Transparent: transparent objects allow light to pass through them. An example of transparent objects is clear glass

In this problem, we have the following objects:

  • Umbrella: it is opaque, light does not pass through it
  • Blanket: it is opaque, light does not pass through it
  • Mirror: It is opaque, since it reflects light (light does not pass through it)
  • Clear glass: it is a transparent object

Therefore, the material that transmits most light is d) clear glass.
