A ray diagram is shown.
Svetlanka [38]

Answer:

It is virtual and behind the mirror

Explanation:

When an image is produced by a mirror, we have the following situations:

- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror

- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror

Moreover:

- The image is said to be real if it is in front of the mirror

- The image is said to be virtual if it is behind the mirror

In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.

if S = at² + bt + c, where S is the distance, and t is the time, find the correct unit of a, b and c​
oksian1 [2.3K]

Answer:

a is in units of \frac{m}{s^{2}}

b is in units of \frac{m}{s}

c is in units of m

Explanation:

We have the following expression:

S=at^{2}+bt+c

Where:

S is the distance, hence its unit is m (meters, assuming we are using the International System of Units)

t is the time, hence its unit is s (seconds)

So, the expression is rewritten as:

m=as^{2}+bs+c

Since the left side of the equation is in meters, the right side must be in meters as well.

In addition, in the right side we have terms that have to added, this means each term must be in meters:

- For the first term a must be in units of \frac{m}{s^{2}} in order to have meters.

- For the second term b must be in units of \frac{m}{s} in order to have meters.

- For the third term c must be in units of m in order to have meters.

Explain the difference between cleavage and fracture
bearhunter [10]

Fracture is the characteristic way a mineral breaks. The difference between cleavage and fracture is that cleavage is the break of a crystal face where a new crystal face is formed where the mineral broke, whereas fracture is the "chipping" of a mineral making it Uneven - A fracture that leaves a rough or irregular surface.

Which of the following is an example of an electric force?
inysia [295]

The example of electric force in the given question is a Plastic wrap sticks to glass bowl containing leftovers. Option A is the right answer.

ELECTRIC FORCE

According to Coulomb's law, the electric force is proportional to the product of the charges and inversely proportional to the square of the distance between them.

The electric force can be:

  • Force of attraction
  • Force of repulsion

The electric force can be exhibited in both static and current electricity. Example of static electricity are;

  • a glass rod rub with fur
  • an ebonite rod rub with silk.
  • e.t.c

The example of electric force in the given question is a Plastic wrap sticks to glass bowl containing leftovers.

The plastic wrap is able to stick to glass bowl container because of the force of attraction between the plastic wrap and the glass bowl container.

Therefore, the correct answer is the option A
