To find the accurate measurement of small cars, the teacher asks students to make all the measurements in centimeters.

Centimeters Measurements:

  • A centimeter is a metric unit of measurement used for measuring the length of an object, It is written as cm
  • Centimeter is one hundredth of a meter, 1 meter is 0.01 cm.

Inches measurements:

  • An inch can be defined as a unit of length in the customary system of measurement. Length in inches is either represented by in or ''.
  • 1 meter is equal to 39.37 inches

here, the cars are small objects.

The number of centimeters is always bigger,

because a centimeter unit is smaller than an inch unit, and it takes more of them when we are measuring.

Hence,

To find the accurate measurement of small cars, the teacher asks students to make all the measurements in centimeters.

Item 4 Which conditions produce the smallest and largest ocean waves? Choose the two correct answers.
Darya [45]

Answer:

strong winds that blow for a long time over a great distance

weak winds that blow for short periods of time with a short fetch

Explanation:

When the winds are weak and blow for short periods, we experience the smallest ocean waves but when there are strong winds over a longer duration, the largest ocean waves are seen. Therefore, the conditions to produce the smallest and largest ocean waves are strong winds that blow for a long time over a great distance and weak winds that blow for short periods of time with a short fetch.

Think Critically Suppose your teacher gave you a slide of an unknown cell. How would you tell whether the cell was from an anima
topjm [15]

Answer:

You will be able to tell whether the unknown cell is from an animal or from a plant through the knowledge of difference between plants and animal cells.

Explanation:

A cell can be defined as the simplest bit of living matter which exhibits a variety of shapes and sizes and that can exist independently.

When a slide of an unknown cell is studied under a microscope, different cell structures would be observed which would be used to conclude if the cell on the slide is a plant or animal cell.

The following features are observed in a plant cell:

--> cellulose cell wall is present

--> Chloroplast is present

--> A large central vacuole is present

--> Centriole is absent

The following features are observed in animal cell:

--> Cellulose cell wall is absent

--> Chloroplast is absent

--> Small vacuoles is present

--> Centriole is present

The difference between a plant and an animal cell can be seen from the features above and a clear knowledge of this will help the student tell whether the unknown cell is from an animal or from a plant.

The Earth has mass ME and average radius RE. The Moon has mass MM and the average distance from the center of mass of the moon t
marusya05 [52]

Answer:

Moment of inertia of Earth about its own axis is given as

I = 9.7 \times 10^{37} kg m^2

Explanation:

Since Earth is considered as solid sphere

So we will have

I = \frac{2}{5}M_eR_e^2

so we will have

I = \frac{2}{5}(5.97 \times 10^{24})(6.371 \times 10^6)^2

so we have

I = 9.7 \times 10^{37} kg m^2

After the ball reaches the top and begins its return back down, by how much does it speed increase each second?
FrozenT [24]

After the ball reaches the top and begins its return back down, it's just a falling object that's been dropped.  

The amount that its downward speed increases every second is just the acceleration of gravity on Earth.

That's <em>9.81 meters per second</em> every second.
