How might error analysis help scientists identify and quantify the

Physics
1 answer:
Naddik [55]3 years ago
6 0

Answer: For producing the error free results of an experiment that identification and quantification of effects of uncertainties are important.

Explanation:

The error analysis is necessary to detect the uncertainties in the measured data or results of the experiment to ensure the validity and acceptability of the results. The errors can be avoided by increasing the precision and accuracy of the measuring instruments. The other factors like changes in the variables of the experiment can also contribute to the errors in the experiment.

It is necessary to perform the multiple trails in an experiment to assure that the results of the experiment are consistent with every trial.

An electric heater draws a steady 15.0A on a 120-V
morpeh [17]

Answer:

1. 1800 W

2. $ 17.3

Explanation:

From the question given above, the following data were obtained:

Current (I) = 15 A

Voltage (V) = 120 V

Time (t) = 20 h per day

Duration = 31 days

Cost = 15.5 cents per kWh

1. Determination of the power.

Current (I) = 15 A

Voltage (V) = 120 V

Power (P) =?

P = IV

P = 15 × 120

P = 1800 W

Thus, 1800 W of power is required.

2. Determination of the cost per month (31 days).

We'll begin by converting 1800 W to KW.

1000 W = 1 KW

Therefore,

1800 W = 1800 W × 1 KW / 1000 W

1800 W = 1.8 KW

Next, we shall determine the energy consumption for 31 days. This can be obtained as follow:

Power (P) = 1.8 KW

Time (t) = 2 h per day

Time (t) for 31 days = 2 × 31 = 62 h

Energy (E) =?

E = Pt

E = 1.8 × 62

E = 111.6 KWh

Finally, we shall determine the cost of consumption. This can be obtained as follow:

1 KWh = 15.5 cents

Therefore,

111.6 KWh = 111.6 KWh × 15.5 cents / 1 KWh

111.6 KWh = 1729.8 cents

Converting 1729.8 cents to dollar, we have:

100 cents = $ 1

Therefore,

1729.8 cents = 1729.8 cents × $ 1 / 100 cents

1729.8 cents = $ 17.3

Thus, it will cost $ 17.3 per month to run the electric heater.

If the initial velocity of an object was -2 meters per second
Shalnov [3]
A :-) for this question , we should apply
a = v - u by t
Given - u = -2 m/s
v = -10 m/s
t = 16 sec
Solution -
a = v - u by t
a = -10 - -2 by 16
a = -12 by 16
( cut 12 and 16 because 2 x 6 = 12 and
2 x 8 = 16 )
( cut 6 and 8 because 2 x 3 = 6 and
2 x 4 = 8 )
a = 3 by 4
a = 0.75 m/s^2

.:. The acceleration is 0.75 m/s^2.

PLZ ANSWER ASAP, I WILL MARK AS BRAINLIEST
MissTica

Answer:

electric potential energy=

\frac{KQq}{r}

so the electric potential energy and distance(r) are inversely proportional.

then, the greatest energy occur in the smallest distance b/n the two balloon.

A ball is thrown into the air with 100 J of kinetic energy, which is transformed to gravitational potential energy at the top of
masya89 [10]

To solve this problem we could apply the concepts given by the conservation of Energy.

During the launch given in terms of kinetic energy and reaching the maximum point of the object, the potential energy of the body is conserved. However, part of all this energy is lost due to the work done by the friction force due to friction with the air, therefore

E_T = PE + KE -W_f

The potential and kinetic energy are conserved and are the same PE = KE and this value is equivalent to 100J, therefore

E_T = 100-W_f

The kinetic energy will ultimately be less than 100J, so the correct answer is C.
