Does California have enough water?
Answer:
As the world's largest, most productive, and most controversial water system, it manages over 40 million acre feet (49 km3) of water per year. Water and water rights are among the state's divisive political issues. Due to the lack of reliable dry season rainfall, water is limited in the most populous U.S. state.

Which of the following accurately describes how scientists use models?
A. To make science seem more complex and inaccessible
B. To take measurements of an object, process, or system as it is in
nature
C. To make direct observations of a natural object, process, or
system
D. To represent objects, processes, and systems that are too large,
too small, or too complex to study directly
Answer:
D
Explanation:
To represent objects, processes, and systems that are too large, too small, or too complex to study directly
The correct option is (d) To represent objects, processes, and systems that are too large, too small, or too complex to study directly.
Scientists employ models to comprehend phenomena they are unable to directly observe. Models aid scientists in their understanding of phenomena, no matter how big or little they may be, such as the universe or an atom. Additionally, they can aid in their understanding of systems like weather patterns.In a range of scientific disciplines, from physics and chemistry to ecology and the Earth sciences, scientific models are employed to explain and forecast the behavior of real things or systems.Models can aid in scientific prediction, understanding of processes, and communication of ideas.

What is the mass of a large ship that has a momentum of 1.60x10^9 kg*m/s and is moving at a velocity of 10m/s?
Answer:
160000000 kg.
Explanation:
p=mv
p=1.6x10^9
v=10m/s
rearrange and substitute:
(1.6x10^9)=m(10)
m=(1.6x10^9)/10
m= 1.6x10^8 kg.

how are electromagnetic waves produced
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.
The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).
Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.
Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

Radon-220 is a radioactive gas. It escapes from underground rocks and causes a large part of the natural background radiation in the United Kingdom. It has an atomic number of 86. How many neutrons are there in its nucleus?
Answer: 134 neutrons are there in the nucleus of Radon-220
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Thus, number of protons = atomic number = 86
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
220 = 86 + Number of neutrons
Number of neutrons = 134

What differentiates one layer of the atmosphere from one another?
Please help
Answer: The stratosphere and the troposphere are defined by the variation in temperature with height. Within a troposphere, the temperature drops as altitude increases, and drops fast enough for convection to occur. Whereas within a stratosphere, the temperature rises with increasing altitude. Features of the atmosphere change with altitude: density decreases, air pressure decreases, temperature changes vary. Different temperature gradients create different layers within the atmosphere. The lowest layer is the troposphere where most of the atmospheric gases and all of the planet's weather are located.

Actually Welcome to the Concept of the Potential Energy.
Here lets calculate it one by one ;-
1.) P = mgh ==> 100*9.81*202===> 198162 Joules
2.) P = mgh ==> 90*9.81*202 ==> 178345.8 Joules
3.) P = mgh ===> 45*9.81*202 ===> 89172.9 Joules
4.) P = mgh ===> 58*9.81*202 ===> 114933.96 Joules
5.) P = mgh ===> 0.001*9.81*202 ===> 1.981 Joules
6.) P = mgh ===> 1.00*9.81*202 ===> 1981.62 Joules
7.) P = mgh ===> 1.998*9.81*202 ==> 3959.27 Joules
8.) P = mgh ===> 1.5*9.81*202 ===> 2971.43 Joules
9.) P = mgh ===> 0.1*9.81*202 ===> 198.162 Joules.

How many seconds will it take for a the International Space Station to travel 450 km at a rate of 100 m/s?
Time = (distance) / (speed)
Time = (450 km) / (100 m/s)
Time = (450,000 m) / (100 m/s)
Time = 4500 seconds (that's 75 minutes)
Note:
This is about HALF the speed of the passenger jet you fly in when you go to visit Grandma for Christmas.
If the International Space Station flew at this speed, it would immediately go ker-PLUNK into the ocean.
The speed of the International Space Station in its orbit is more like 3,100 m/s, not 100 m/s.
Please help, it’s the last question and I’m bad at Physics
Answer:
The end velocity of the sculpture is 7.00 m/s²
Explanation
The equation needed here is v = √(2gh). Let's do it:
v = √(2 × 9.8m/s² × 2.5m)
v = √(49.0 m²/s²)
v = 7.0m/s
Funny enough the numbers given don't have the accuracy demanded. We're given is 2.5m which is only accurate to the tenths, and 30kg which is only accurate to the nearest integer. Also, presumably the acceleration due to Earth gravity that's provided is only 9.8m/s², so that's still only the nearest tenth. So taking those and asking to find the answer to the nearest hundredth is pointless.
But whatever. The given answer is correct to the nearest hundredth. 7.00m/s² To be sure, I plugged it into a form on a physics page that does exactly that, and the answer they gave was 7.0023745972349, so we have it rounded correctly.
A drone flies upward with a velocity of 5m/s and has a kinetic energy of 90J What is the mass of the drone?
O 5.4 kg
1.9 kg
7.2 kg
3.6 kg
Answer:
m = 7.2 kg
Explanation:
Given that,
The velocity of the drone, v = 5 m/s
The kinetic energy of the drone, E = 90 J
We need to find the mass of the drone. The formula for the kinetic energy of an object is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 90}{(5)^2}\\\\m=7.2\ kg[/tex]
So, the mass of the drone is 7.2 kg.

How fast is a skydiver going after 5 seconds or free fall and how far did he fall
Answer:
It's typically around 120mph. You'll reach this speed a few seconds into your jump, so for those few moments straight out the door, you'll be falling a bit more slowly and therefore covering less distance. We usually estimate around 10 seconds for the first 1,000 feet, then 5 seconds for each 1,000 feet after that.

Explanation:
Which of these is not a standard unit?
a. second
b. metre
c. hand span
d. gram
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".
