Answer:

1.5 %

Explanation:

Given data:

Theoretical value = 9.67 g

Actual value = 9.82 g

Percentage error = ?

Solution:

Formula

<em>percentage error = (Theoretical value - actual value / actual value) ×100</em>

percentage error = 9.67  - 9.82  /9.82  ×100

percentage error = -0.15/ 9.82 ×100

percentage error = -0.015×100

percentage error = 1.5 %

<h3>Answer:</h3>

1.53%

<h3>Explanation:</h3>

We are given;

Experimental value as 9.67 g

Actual measurement as 9.82 g

We are required to calculate the percentage error;

  • Percentage error is given by dividing the absolute value of the difference between the experiment value and the actual value then dividing by the actual value and multiplying by 100.
  • That is;

% error = ((Experimental value -Actual value)÷ Actual value) × 100%

Difference between experimental value and actual value = 9.67 g - 9.82 g

                                                       = -0.15

Therefore, Absolute value = 0.15

Therefore;

% error = (0.15 ÷ 9.82 g) × 100

            = 1.527%

            = 1.53%

Thus, the percentage error is 1.53%

victus00 [196]

Answer:

See explanation

Explanation:

The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.

There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.

In a roller coaster, both the kinetic and potential energy in the car decreases at
Lemur [1.5K]

We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at  each successive hill because of  the force of gravity which converts potential  energy into  kinetic energy.

<h3>What are potential and kinetic energy?</h3>
  • Potential energy is referred to as <em><u>positional energy</u></em>.
  • This means that the object in question gains energy based on its position relative to others.
  • Kinetic energy is the energy of movement.
  • Gravity causes the roller coaster to fall, losing potential energy.
  • This causes it to gain all of the potential energy as kinetic energy.
  • Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

What Is Photosynthesis?​
irina1246 [14]

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
