Reika [66]3 years ago
4 0

Answer:

The iron bar becomes a magnet.

Explanation:

Remember the coils of a solenoid carry current, from Fleming's left hand rule, the coil experiences a force which acts normally to the direction of current. And this force is magnetic force

If the loading is 0.4, the coinsurance rate is 0.2, the number of units of medical care is 100, and the number of units of medic
s344n2d4d5 [400]

Answer:

72  is the premimum of the insurance.

Explanation:

Below is the given values:

The loading = 0.4

Coinsurance rate = 0.2

Number of units = 100

Total number of units = 100 * 0.4 = 40

Remaining units = 60 * 0.2 = 12

Add the 60 and 12 values = 60 + 12 = 72

Thus, 72  is the premimum of the insurance.

A rock group is playing in a bar. Sound emerging from the door spreads uniformly in all directions. The intensity level of the m
LekaFEV [45]

Answer:

1779299.7m

Explanation:

From formulas in acoustic sound, we know that sound intensity is inversely proportional to the square of the distance away.

Thus;

I2/I1 = r2²/r 1²

So,

∆L = 10 log (I2/I1)

Where ∆L is the intensity of music and r1 and r2 are distances away.

∆L=10log 10(r1²/r2²)

∆L=10log 10(r1/r2)²

∆L= - 20log 10(r1/r2)

r2 = r1•10^(-∆L/20)

​From the question,

∆L = 116 Db

r1 = 2.82m

Thus,

r2 = 2.82 x 10^(116/20)

r2 = 2.82 x 630957.34 = 1779299.7m

victus00 [196]

Answer: A - a gap on each side of the clutch disk facing when disengaged

Explanation:

A clutch switch is used to ensure the clutch is disengaged

or Prevent the engine from starting unless the clutch pedal is depressed

When a clutch is disengageda gap will be on each side of the facing.

Estimate under what set of conditions it is possible, despite the spherical shape of the working electrode, to use linear diffus
goldfiish [28.3K]

When the experimental measurements diverge at very low values of the voltages. When the ratio of current to saturated current is very small. That is, i/I less than or equal to 1/100. When there is a finite current at Voltage

V = 0

Diffusion will have influence on current - voltage curve in the working electrode which is ionization detector.

The estimation under set of conditions that is possible, despite the spherical shape of the working electrode, to use linear diffusion equations to theoretically predict the current vs voltage curve expected in this experiment will be:

  • When the experimental measurements diverge at very low values of the voltages
  • when the ratio of current to saturated current is very small. That is, i/I less than or equal to 1/100
  • When there is a finite current at Voltage V = 0

Where

i = electric current

I = saturated current

V = voltage supplied

The curve expected will therefore give exponential curve from positive to negative domain because of the diffusion of ions from different directions
