How does uncertainty relate to measurements and calculations made during an investigation?

Physics

Nana76 [90]3 years ago

Answer:

Explanation :Uncertainty in measurements and calculations means difference between actual and measured data. We can say that all measurements have some degree of uncertainty. It can be of two types-1. Systematic error (because of error in measuring instrument) 2. Random error (human errors such as- delay in starting, delay in stopping).

Systematic errors are consistent in magnitude and direction so they can be easily removed by additive or proportional corrections while random errors vary in magnitude and direction and can not be easily removed.

Uncertainty means that your result may be very random, so you can't trust the first or second or so observation, making several samples critical for accuracy. <span />

What causes an object to move, change direction or change speed?
Wittaler [7]
I believe it would be an unbalanced force. Because the forces are unbalanced, one side is stronger and, therefore, the object will move.

Answer:

No sand doesn't stay sand forever.

Explanation:

  • We may have a thought that the sand we see on the beach areas are always the same one for eternal, but it is not true.
  • Due to different activities like beach nourishment, sand replenishment etc. the sand in the beach areas are changed and replaced.
  • If the sand remained there for long time, it also affects the sand eating organisms and plants.

A box, compressing a spring by 4 m, is loaded and ready. Moments later the 8.0 kg box has been launched with
Mrac [35]

Answer:

50 N/m

Explanation:

Elastic energy = kinetic energy

EE = KE

½ kx² = ½ mv²

½ k (4 m)² = ½ (8.0 kg) (10.0 m/s)²

k = 50 N/m

Dylan has two cubes of iron. The larger cube has twice the mass of the smaller cube. He measures the smaller cube. Its mass is 2
liubo4ka [24]

Answer:

The volume of the larger cube is 5.08 g/cm³.

Explanation:

Given that,

Mass of smaller cube = 20 g

Density of smaller cube \rho= 7.87 g/cm^2

Dylan has two cubes of iron.

The larger cube has twice the mass of the smaller cube.

M_{l}=2m_{s}

Density is same for both cubes because both cubes are same material.

The density is equal to the mass divided by the volume.

\rho=\dfrac{m}{V}

V=\dfrac{m}{\rho}

Where, V = volume

m = mass

\rho=density

We need to calculate the volume of smaller mass

The volume of smaller mass

V_{s}=\dfrac{m_{s}}{\rho_{s}}

V_{s}=\dfrac{20}{7.87}

V_{s}=2.54\ cm^3

Now, We need to calculate the volume of large cube

V_{l}=\dfrac{m_{l}}{\rho_{l}}

V_{l}=\dfrac{2\times20}{7.87}

V_{l}=5.08\ g/cm^3

Hence, The volume of the larger cube is 5.08 g/cm³.
