Answer:

\boxed {\boxed {\sf 0.225 \ Newtons}}

Explanation:

We are asked to find the force being applied to a book. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

F= ma

The mass of the book is 0.75 kilograms and the acceleration is 0.3 meters per square second. Substitute these values into the formula.

  • m= 0.75 kg
  • a= 0.3 m/s²

F= 0.75 \ kg * 0.3 \ m/s^2

Multiply.

F =0.225 \ kg * m/s^2

1 kilogram meter per second squared is equal to 1 Newton. Therefore, our answer of 0.225 kilogram meters per second squared is equal to 0.225 Newtons.

F= 0.225  \ N

<u>0.225 Newtons of force</u> are applied to the book.

Sliva [168]

Answer: 1.33

Explanation:

We would apply Snell's law which is expressed as

niSinθi = nrSinθr

where

θi = angle of incidence

θr = angle of refraction

ni = index of refraction of the incident medium(air)

nr = index of refraction of the refractive medium(liquid in this case)

From the information given,

ni = 1(index for air)

θi = 37

θr = 27

By substituting these values into the formula, we have

1 * sin37 = nr * sin27

nr = sin37/sin27

nr = 1.33

The index of the liquid is 1.33

Before using a string in a comparison, you can use either the To Upper method or the To Lower method to convert the string to up
diamong [38]

Answer:

True, check attachment for code

Explanation:

To convert java strings of text to upper or lower case, we can use and inbuilt methods To Uppercase and To lower case.

The first two lines of code will set up a String variable to hold the text "text to change", and then we print it out.

The third line sets of a second String variable called result.

The fourth line is where the conversion is done.

We can compare the string

We can compare one string to another. (When comparing, Java will use the hexadecimal values rather than the letters themselves.) For example, if we wanted to compare the word "Fat" with the word "App" to see which should come first, you can use an inbuilt string method called compareTo.

Check attachment for the code

Help me define this please<br><br> Latitude (Tropical vs Temperate vs Polar)
morpeh [17]

Answer: Tropical Zone

The tropical climate zone stretches from the Tropic of Cancer at 23.5 degrees north latitude to the Tropic of Capricorn at 23.5 degrees south latitude, with the equator centered within this zone. Climate within the tropical zone varies from the tropical wet regions of the rain forest, to the drier arid and semi-arid climate of north Africa or central Australia. Within the tropical wet zone, the weather remains hot and muggy, with frequent rainfall and little temperature variation. The arid and semi-arid regions experience wet, warm summers and cooler, drier winters, with much greater temperature variation than the tropical wet zone.

Temperate Zone

Extending from the southern edge of the Arctic Circle to the Tropic of Cancer in the northern hemisphere, and the northern edge of the Antarctic Circle to the Tropic of Capricorn in the southern hemisphere, the temperate climate zone falls between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year of any climate zone. Climate within the temperate regions ranges from the cold, snowy winters of New England to the balmy, moderate weather associated with the Mediterranean or Southern California. Much of the United States, Europe and the southern half of South America fall within this climate zone.

Polar Zone

The polar climate zones fill the areas within the Arctic and Antarctic Circles, extending from 66.5 degrees north and south latitude to the poles. Characterized by a short, cool summer and long, bitterly cold winter, the polar zone features frequent snowfall, particularly during the winter months. The far northern portions of Canada, Europe and Russia fall within this climate zone. Farther north and south, the ice caps that make up Greenland and Antarctica represent a sub-zone of the polar climate region known as the ice cap zone. Within the ice caps, temperatures rarely, if ever, rise above freezing, even during the warmest months of the years.
