In November 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. The chunk of ice was e

stimated to be 98 mi long, 25 mi wide, and 750 ft thick. A typical backyard swimming pool contains about 24,000 gallons of water. How many of these pools could you fill from the water in this iceberg? (Assume the iceberg is a rectangular solid of the above dimensions and consists of water only). Express answer in scientific notation.

<h2>Answer:</h2>

1.58  × 10∧16 pools.

<h3>Explanation:</h3>

Given:

Length of ice berg= 98 miles = 1557716 meters

Width of iceberg = 25 miles = 40233.6 meters

Thickness of iceberg = 750 ft = 230 meters

Volume of water in a swimming pool = 24,000 gallons = 90850 liters

The volume of the ice berg:

Volume = Length . width . thickness

Volume = 1557716 . 40233.6 . 230 = 1,441, 468, 016, 5248 m3 =  1,441, 468, 016, 5248 × 10 ∧3 L.

1 pool contains liters of water:  90850 liters

1,441, 468, 016, 5248 × 10 ∧3 liters contains = 1/90850 . 1,441, 468, 016, 524.8 × 10 ∧3 .

= 1.100 .  1,441, 468, 016, 5248 × 10 ∧3 L.

= 1.58  × 10∧16 pools.

Hence 1.6 × 10∧16 pools will be filled with that chunk of ice.

Answer:

1.5964\times 10^{10} pools can be filled from the water in this iceberg.

Explanation:

Length of an iceberg ,l= 98 miles  =157.71 km

(1 mile = 1.60934 km)

Width of an iceberg,w = 25 miles  = 40.23 km

Depth of an iceberg ,h= 750 feet = 0.2286 km

1 foot = 0.0003048 km

Volume of an iceberg, V= l × w × h  = 1,450.3923 km^3

1 km^3=10^{12} dm^3

V=1.4504\times 10^{15} dm^3=1.4504\times 10^{15} L

1 dm^3= 1L

Number of swimming pools that can be filled by the water in an iceberg be x.

Volume of swimming pool = v = 24,000 gallons = 90,849.84 L

( 1 gal = 3.78541 L)

v = 24,000 \times 3.78541 L=90,849.84 L

x\times v=V

x=\frac{V}{v}=\frac{1.4504\times 10^{15} L}{90,849.84 L}

x=1.5964\times 10^{10}

1.5964\times 10^{10} pools can be filled from the water in this iceberg.

Schach [20]

In the extraction process of steel, one of the step is purification of the iron used to make the steel. In which pure oxygen is blown on the steel at high temperature so that the carbon percentage present in the steel can be thrown out in the form of gas. The process occurs at high temperature which is called combustion process. The reaction occurs can be shown as- C(s)+O_{2}→CO_{2} (g) + CO (g). In presence of excess oxygen, the produced carbon mono oxide (CO) converts to carbon di-oxide. The reaction is CO(g) + O_{2}(g) → CO_{2} (g). From the density of the evolved gas one could identify the gas. If the gas density is 1.77g/L which is very close to the standard density of CO_{2} i.e. 1.80g/L, the gas is carbon dioxide only.

If a gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm?
Llana [10]
Since the temperature is constant, therefore, this problem can be solved based on Boyle's law.
Boyle's law states that: " At constant temperature, the pressure of a certain mass of gas is inversely proportional to its pressure".

This can be written as:
P1V1 = P2V2
where:
P1 is the initial pressure = 1 atm
V1 is the initial volume = 3.6 liters
P2 is the final pressure = 2.5 atm
V2 is the final volume that we need to calculate

Substitute with the givens in the above mentioned equation to get the final volume as follows:
P2V1 = P2V2
1(3.6) = 2.5V2
3.6 = 2.5V2
V2 = 3.6 / 2.5 = 1.44 liters

A 75 lb (34 kg) boy falls out of a tree from a height of 10 ft (3 m). i. What is the kinetic energy of the boy when he hits the
Jobisdone [24]

Answer:

Kinetic energy of boy just before hitting the ground is \approx1000 J.

Speed of boy just before hitting the ground is 7.67 m/s

or 17.16 mi/hr.

Explanation:

Given that:

Mass of boy = 75lb = 34 kg

Height, h = 10ft = 3m

To find:

Kinetic energy of boy when he hits the ground.

<em>As per law of conservation of energy The potential energy gets converted to kinetic energy.</em>

<em></em>

<em></em>\therefore<em> </em>Kinetic energy at the time boy hits the ground = Initial potential energy of the boy when he was at the Height 'h'

The formula for potential energy is given as:

PE = mgh

Where m is the mass

g is the acceleration due to gravity, g = 9.8 m/s^2

h is the height of object

Putting all the values:

PE = 34 \times 9.8 \times 3 \approx 1000\ J

Hence, Kinetic energy is \approx1000 J.

Formula for Kinetic energy is:

KE = \dfrac{1}{2}mv^2

where m is the mass and

v is the speed

Putting the values and finding v:

1000 = \dfrac{1}{2}\times 34 \times v^2\\\Rightarrow v^2 = 58.82\\\Rightarrow v = 7.67\ m/s

Given that:

1 m = 1.094 yd and 1 mi = 1760 yd

\Rightarrow 1609\ m = 1\ mi

Converting 7.67 m/s to miles/hour:

\dfrac{7.67 \times 3600}{1609}=17.16\ mi/h

Janine is trying to separate some ethanol from water. Which method should she use does anyone know this
GuDViN [60]

To separate some ethanol from water, Jane needs to use the method of simple distillation.

Simple distillation is a separation method in which two liquids can be separated from each other based on differences in boiling point.

Since water has a higher boiling point than ethanol, ethanol is collected first as the distillation proceeds.
