If an object 18 millimeters high is placed 12 millimeters from a diverging lens and the image is formed 4 millimeters in front of the lens, what is the height of the image? A. 6 millimeters
B. 8 millimeters
C. 14 millimeters
D. 22 millimeters

Answers

The correct answer is letter A. 6 millimeters. If an object 18 millimeters high is placed 12 millimeters from a diverging lens and the image is formed 4 millimeters in front of the lens, the height of the image is 6 millimeters.

Solution:
18 / x = 12 / 4
12x = 72
x = 6mm

The process by which atoms are arranged to form a material with a crystal shape is called

Answers

Explanation:

The process by which atoms are arranged to form a material with a crystal shape is called crystallization.

With the help of crystallization process we can purify a solid compound.

For example, ice and snowflakes occur due to crystallization of water.

In this process, small quantity of desired solvent is added into the impure solid. Then it is heated to let the solid dissolve and after that it is cooled down so that crystals are formed. Then with the help of vacuum filtration pure solid is extracted.

Answer:

Crystallization is the correct answer.

Two 100 kg bumper cars are moving toward each other in opposite directions. Car A is moving at 8 m/s and Car B at –10 m/s when they collide head–on. If the resulting velocity of Car B after the collision is 8 m/s, what is the velocity of Car A after the collision?(I saw this question was asked previously, but the person did not provide the correct answer...)

Answers

Answer:

$v_a = -10 m/s$

so car A will move with speed 10 m/s in opposite direction

Explanation:

As we know that when two cars collide then the momentum of two cars will remains conserved

so here we have

$P_i = P_f$

mass of two cars = 100 kg

speed of car A = 8 m/s

speed of car B = - 10 m/s

after collision the speed of car B = +8 m/s

now by momentum conservation equation

$m_1v_(1i) + m_2v_(2i) = m_1v_(1f) + m_2v_(2f)$

so we have

$100(8) + 100(-10) = 100(v_a) + 100(8)$

so we have

$v_a = -10 m/s$

so car A will move with speed 10 m/s in opposite direction

50 J of work was performed in 20 seconds. how much power was used to do this task?

Answers

   Power = (amount of work done) / (time to do the work).

   = (50 J) / (20 sec)

   = 2.5 joule/sec = 2.5 watts .

Validity is __________.a. concerned with the relationships of random error with systematic error. b. equal to the true score plus the systematic error. c. equal to the true score plus systematic error minus random error. d. concerned with the extent to which differences in scores reflect true differences in the characteristic. e. concerned with the extent to which differences in scores reflect instability in the measurements.

Answers

Answer: the correct answer is option d.

Explanation:

Validity is concerned with the extent to which differences in scores reflect true differences in the characteristic.

Answer:

d. concerned with the extent to which differences in scores reflect true differences in the characteristic.

Explanation:

Validity is the level of accuracy of a measurement under research or test. A measurement is said to be valid if its result is closely related to real world values. Validity in research shows how sound one's research is. In data it means getting a true representation of the data a researcher is claiming to measure. To measure validity, the measurement must have internal consistency and good test-retest reliability.

Types of validity.

Validity can be content, construct, face and criterion.

The diagram shows two bar magnets. They are cut along the dashed line, and then the two marked ends are placed near each other. Which statement best explains how the pieces will react?

A) The pieces will repel because the cut end of the top magnet is not a magnetic pole.

B) The pieces will attract because the cut end of the top magnet is not a magnetic pole.

C) The pieces will repel because the cut end of the top magnet is a south pole.

D) The pieces will attract because the cut end of the top magnet is a north pole.

Answers

The answer to this problem is "OPTION C" i.e. The pieces will repel because the cut end of the top magnet is a south pole.

A magnet as a collection of tiny magnets, called magnetic domains. Each of these domain reinforces the magnetic fields of the other domains and hence the net magnetic field of magnet is generated. Each one of these domains have a tiny north and south pole. If you cut a magnet in half (along the line suggested in the problem), the newly cut faces will become the new north or south poles of the divided parts.
