When earth completes a full rotation, how much time has elapsed?

DIA [1.3K]

The answer is; 24 hours.

Scientists called the full rotation of the earth a day and divided it into 24 hours on the clock. This means from sunrise to next sunrise. They also divided the earth into latitudes that indicate time zones. When one point on earth rotates and return to the same position in space, it has lapsed 24 hours.

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a

Katyanochek1 [597]

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

$Length = 10cm$

Robert:

1 glass marble

$Diameter = 10cm$

Susan:

1000 glass marble

$Diameter = 1cm$

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

$Volume = Length^3$

Substitute 10cm for Length

$Volume = 10^3$

$Volume = 1000cm^3$

Next, calculate the volume of Robert's glass

Volume is calculated as:

$Volume = \frac{4}{3}\pi r^3$ ---- Volume of a sphere

Where

r = radius

$r = \frac{1}{2} * Diameter$

$Diameter = 10cm$ --- Given

Substitute 10 for diameter

$r = \frac{1}{2} * 10cm$

$r = 5cm$

So:

$Volume = \frac{4}{3}\pi r^3$

$Volume = \frac{4}{3} * \frac{22}{7} * 5^3$

$Volume = \frac{4}{3} * \frac{22}{7} * 125$

$Volume = 523.8cm^3$

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

$Volume = \frac{4}{3}\pi r^3$ ---- Volume of a sphere

Where

r = radius

$r = \frac{1}{2} * Diameter$

$Diameter = 1cm$ --- Given

Substitute 1cm for diameter

$r = \frac{1}{2} * 1cm$

$r = 0.5cm$

Substitute 0.5cm for radius in $Volume = \frac{4}{3}\pi r^3$

$Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3$

$Volume = \frac{4}{3} * \frac{22}{7} * 0.125$

$Volume = 0.5238$

But there are 1000 glasses.

So, the volume of 1000 glasses is:

$Volume = 0.5238 * 1000$

$Volume = 523.8cm^3$

--------------------------------------------------------------------------------------------------------------

For Robert:

$Volume = 523.8cm^3$

For Susan:

$Volume = 523.8cm^3$

Since, they have the same volume.

Both boxes have the same amount of empty space

1. How was this viral entry similar to what Dede Koswara experienced with HPV?

erastova [34]

Dede Koswara, nicknamed the Tree Man, teaches us about the importance of wearing new gloves when working with potentially HPV patients. because if you use the same glove you can transmit diseases from a patient like Dede to another healthy one.

<h3>What is the story of Dede Koswara?</h3>

He accidentally cut his knee, where a small wart grew on his leg, which eventually spread all over his body.

The solution was when he found US dermatology expert Dr. Anthony Gaspari of the University of Marlyland, he concluded that Dede's disease was caused by the human papilloma virus (HPV).

The human papilloma virus (HPV) is responsible for a high number of infections that, in most cases, do not present symptoms and are spontaneously regressed. This is one of the most common sexually transmitted infections worldwide. The human papilloma virus encompasses more than 200 related viruses.
