Answer:
117 millimeters = 0.117 meters
Explanation:
This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.

Q+ ( poistive ion ) is an ion of element Q.
What has the highest value in the ion?
The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

HELP WITH THIS EASY SCIENCE WORK
Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.
(2) two kidneys we have.
(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.
(4)Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.
(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.
(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.
(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

What happens to the moon every month? Science
Answer:
Every month Earth's moon goes through its phases, waning and waxing in its constant transformation from new moon to full moon and back again. This lunar cycle happens in part because the moon does not produce its own light; the silvery glow we see comes from sunlight reflecting off the moon's monochrome surface.
Explain how airbag gets deployed ? Explain the reactions involved?
Answer:
Let’s get back to simple physics and the laws of motion. Your car and everything in it are traveling in a given direction, to stop in requires force be applied in the opposite direction over a period of time. This occurs extremely quickly in an accident and the force is greater because the time the opposing force is acting on the vehicle is very short. The airbag system is designed to offer you protection from the violent forces exerted on you during an accident.
There are three main components to your airbag system, the bag, the inflator and the sensor. The sensor must register a collision force roughly equal to hitting a brick wall at 10 to 15 mile per hour before it will trigger the airbag inflation. Once tripped the airbag system inflates through a chemical reaction between sodium azide (NaN3) and potassium nitrate (KNO3) which creates nitrogen gas. An igniter is set off which quickly burns the chemical fuel and creates the gas needed for expansion. The bag then blows out of its storage in a split-second. Immediately after inflation, when the chemical burn is complete, the airbag begins to deflate as the gasses escape from holes in the fabric.

What is nitrogen cycle?Nitrogen cycle is defined as a biogeochemical process that converts inert nitrogen in the atmosphere into a form that living organisms can use.
It can also be defined as a cyclical process in which nitrogen travels through both living and nonliving things,
There are seven steps of nitrogen cycle.
Nitrogen fixationAssimilation AmmonificationNitrificationDenitrificationDissimilatory nitrate reduction to ammoniaAnaerobic ammonia oxidationBiogeochemical cycle is defined as the process by which a chemical substance cycles through Earth's biotic and abiotic compartments.

List four factors that affect precipitation
Topic scowmce
Precipitation.
Humidity is the amount of water vapour in the air. This is produced by the evaporation
of water from oceans, lakes, rivers, wetlands and plants.
When water evapour in the air cools, it condenses. In other words, it becomes liquid and
forms little drops. These droplets form clouds.
When the droplets are small, they remain suspended in the atmosphere. But they often
become colder and their size and weight increases When they become too heavy to
remain suspended in the air, they fall to the Earth’s surface. We call this precipitation,
which may be rain, snow or hail.
Factors affecting precipitation.
Different areas of the Earth’s surface receive different amounts of precipitation.
Latitude: it rain more in the areas near the equator than in the temperature
zones and polar regions. The temperature is higher near the Equator so there is
more evaporation.
Altitude: it rains more in high areas than in low areas.
Level of humidity: it rains more on the coast than inland. Seas are a source of
humidity.
Precipitation is measured in millimeters (mm) per square matre.

The volume of a gas is 200mL at 2.0atm. What will it's volume be at 4.0atm?
Answer:
V = 100 ml
Explanation:
P1V1 = P2V2
P1 = 2.0 atm
V1 = 200ml
P2 = 4.0 atm
V2 = ?
(2.0)(200) = (4.0)V2
400 = (4.0)V2
V2 = 100

I In a smaller room, such as a bathroom, the reflected sound can reverberate (echo in many directions) off the smooth tile. Why do you think people enjoy singing in the shower?
Answer:
See explanation
Explanation:
It is common knowledge that quite a number of people enjoy singing in the shower. There are reasons for this!
In the shower, there are many surfaces that reflect the sound of your voice as you sing. That makes your voice to sound more powerful and have more volume.
The reverberation of the sound makes the sound of your voice stronger and more intense altogether enriching the music produced as you sing.
