does uranium use steam?
Answer:
Yes.
Explanation:
Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together onto sealed metal tubes called fuel rods. The heat created by fission turns the water into steam.

Denver, Colorado is located near the rocky mountains. Which list of controls below would have the strongest influence on the weather in Denver.
A ) Ocean currents, distance from large bodies of water, and altitudes
B ) Altitude, topography, and ocean currents.
C ) Latitude, altitude, and topography
D ) Topography, ocean currents, and latitude.
Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.
Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.

Explanation:
Dietary fiber contains an indigestible material known as cellulite. This is false statement.
What is Dietary fiber?Plant substances that are not broken down by human digestive enzymes are referred to as dietary fiber.
Only lignin and a few polysaccharides were recognized as meeting this criterion in the late 20th century, but resistant starch and oligosaccharides were listed as dietary fiber components in the early 21st century.
The phrase "all polysaccharides and lignin, which are not digested by the endogenous secretion of the human digestive tract" is commonly used to define dietary fiber.
At the moment, the majority of animal nutritionists either use a physiological definition, which states that "dietary components resistant to breakdown by mammalian enzymes," or a chemical definition, which states that "the sum of non-starch polysaccharides (NSP) and lignin."

Complete question:
A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat
Answer:
(1) The impulse exerted by the ball is 7.2 kg.m/s
(2) The average force exerted on the ball by the bat is 600 N.
Explanation:
Given;
mass of the baseball, m = 0.144 kg
velocity of the baseball, v₁ = 20 m/s
velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)
The impulse exerted by the ball is calculated as follows;
J = ΔP = mv₁ - mv₂
ΔP = m(v₁ - v₂)
ΔP = 0.144 [20 - (-30)]
ΔP = 0.144 ( 20 + 30 )
ΔP = 0.144 (50)
ΔP = 7.2 kg.m/s
The average force exerted on the ball by the bat is calculated as;
[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

Speed = Distance Time Velocity = 1. Find the velocity of a truck that travels 75miles north in 2.5 hours? List: Equation: Substitution: Answer with units:
Answer:
187.5 m/s (i think)
Explanation:
If you use the formula V= T times displacement you can find this out by doing the following-
Displacement equals 75 m
T equals 2.5 hrs
75x2.5= 187.5
and since velocity is measured in m/s, it becomes
187.5 m/s

The current in the wires of a circuit is 60.0 milliAmps. If the
voltage impressed across the ends of the circuit were
doubled and the resistance were tripled, then its new current
would be ___ milliAmps.
Answer:
I' = 40 mA
Explanation:
Given that,
The current in the wires of a circuit is 60.0 mA.
If the voltage impressed across the ends of the circuit were doubled and the resistance were tripled such that,
V' = 2V and R'=3R
The relation between current, voltage and resistance is given by :
V = IR
Let I' be the new current. So,
V'=I'R'
⇒ [tex]I'=\dfrac{V'}{R'}\\\\I'=\dfrac{2V}{3R}\\\\I'=\dfrac{2}{3}\times \dfrac{V}{R}\\\\I'=\dfrac{2}{3}\times I\\\\I'=\dfrac{2}{3}\times 60\\\\I'=40\ mA[/tex]
So, the new current would be 40 mA.
What will happen when two neutral objects are rubbed together?
Answer:
I hope this will help you
Explanation:
When two neutral objects come into contact--especially in a dry environment--electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. Objects with like charges repel each other, while those with opposite charges attract each other. This phenomenon--in which objects acquire an electric charge and exert a force on one another--is what we call static electricity.

A tugboat is pulling a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat.
Available options are:
A. –4500 N
B. –2500 N
C. 2500 N
D. 4500 N
Answer:
-4500 N
Explanation:
Given that we have F₁ = 3000N? (force of the barge)
the force of the tugboat is F '
To pull the barge, the force of the tugboat must be greater than or equal to the force of the barge.
Hence, according to Newton's third law which states that for every action or force in nature, there is an opposite reaction.
Therefore considering the available option the correct answer is "- 4500N, " this is because it is greater than the force of the barge and it's in opposition to the force exerted.
Answer:
The answer is -4500 N

Why are images reflected from a rough surface not as clear as those reflected from a smooth
surface?
Answer:
Just as images are reflected from the surface of a mirror, light reflected from a smooth water surface also produced a clear image. ... Consequently, the outgoing rays are reflected at many different angles and the image is disrupted. Reflection from such a rough surface is called diffuse reflection and appears matte.
