How does uncertainty relate to measurements and calculations made during an investigation?
Rom4ik [11]

there here is your answer to your question

Uncertainty in measurements and calculations means difference between actual and measured data. We can say that all measurements have some degree of uncertainty. ...

a furnace supplies 28kW of thermal power at 300C to an engine and exhausts waste energy at 20C. At the very best, how much work
DochEvi [55]

Answer:

The amount of work we could expect to get out of the system per second = 28,000J/s

Explanation:

Given the power supplied to the system as  28kW;

Energy = power / time

At very best, the amount of work we could expect to get out of the system per second = 28,000 W / 1 second =  28,000J/s

Therefore, for a a furnace which supplies 28kW of thermal power at 300C to an engine and exhausts waste energy at 20C.

At the very best, the amount of work we could expect to get out of the system per second = 28,000J/s

which of the four forces makes paint cling to a wall ?which force makes adhesive sticky?which force makes wax to stick a car ?
True [87]

Answer:

This question is incomplete

Explanation:

The question is incomplete because of the absence of options.

However, <u>the force that makes a paint cling to a wall is adhesive force</u>. Adhesive force is the force between two unlike substances like a liquid clinging to a solid surface.

The force between adhesives or glue is also the force that makes them sticky. <u>This force is referred to as cohesive force</u>. This is a force found in between similar molecules (unlike adhesive force found between dissimilar molecules).

<u>The force that makes wax to stick to a car is electromagnetic force</u>. This is a force between charged particles; whether they appear to be moving or not. These particles of opposite charges come together to form a neutral force. In this case, charged atoms of the car and the wax come together (which causes what we see as the wax sticking to the car).

The valu
natulia [17]

Answer:

\% Error = 2.6\%

Explanation:

Given

x: 1.54, 1.53, 1.44, 1.54, 1.56, 1.45

Required

Determine the percentage error

First, we calculate the mean

\bar x = \frac{\sum x}{n}

This gives:

\bar x = \frac{1.54+ 1.53+ 1.44+ 1.54+ 1.56+ 1.45}{6}

\bar x = \frac{9.06}{6}

\bar x = 1.51

Next, calculate the mean absolute error (E)

|E| = \sqrt{\frac{1}{6}\sum(x - \bar x)^2}

This gives:

|E| = \sqrt{\frac{1}{6}*[(1.54 - 1.51)^2 +(1.53- 1.51)^2 +.... +(1.45- 1.51)^2]}

|E| = \sqrt{\frac{1}{6}*0.0132}

|E| = \sqrt{0.0022}

|E| = 0.04

Next, calculate the relative error (R)

R = \frac{|E|}{\bar x}

R = \frac{0.04}{1.51}

R = 0.026

Lastly, the percentage error is calculated as:

\% Error = R * 100\%

\% Error = 0.026 * 100\%

\% Error = 2.6\%
