Answer:
Yes
Explanation:
Because the call can evaporate from the water.
Answer:
A centrifuge is utilized to isolated little sums of strong held in suspension from the fluid. For case, chalk from water. The centrifuge contains test-tubes that are spun around at tall speed that causes the strong to sink to the foot of the tube. The fluid is the tapped (poured off) clearing out the strong behind.

Three components in a parallel circuit have individual resistances of r1, r2, and r3. What formula can you use to determine the total resistance of the circuit?
A. R=r1+r2+r3
B. R=1r1+1r2+1r3
C. 1R=r1+r2+r3
D. 1R=1r1+1r2+1r3
Answer:
D. 1R=1r1+1r2+1r3
Explanation:
If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1R=1r1+1r2+1r3.

1. Why do you think it is important for people to know when the tides will be high and/or low?
Many reasons. Here are a couple:
1.) Water depth for the draft of incoming ships/vessels so they do not run aground.
2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.

A sports car starts at rest at the starting marker then picks up speed, then passes the finish marker in 4.1 seconds. The markers are separated by 120 meters. What is the car's speed at the second marker?
Answer:
S=29.298m/s
Explanation:
Use S=d/t
So, S=120m/4.1s= 29.298m/s

Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are:
Treated glass = 0.75 J/g • °C
Aluminum = 0.90 J/g • °C
Stainless steel = 0.50 J/g • °C
Copper = 0.39 J/g • °C
Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?

An object is most likely to become electrically charged by gaining or losing which type of particles?
neutral particles
positive particles
negative particles
none of the above
Answer:
negative particles
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Hence, an object is most likely to become electrically charged by gaining or losing negative particles.
Calculate the density of mass 150 grams and volume 35 〖cm〗^3
Explanation:
Mass =150g = 0.15kg
Volume= 35cm^3 = 0.35m^3
Density= Mass×Volume
= 0.15kg × 0.35m^3
= 0.05 kg m^3

how do you find the kinetic energy of an object?
Answer:
KE = 1/2 * m * [tex]v^{2}[/tex]
Explanation:
use the formula:
KE = 1/2 * m * [tex]v^{2}[/tex]
KE = kinetic energy in joules (J)
m = mass in kg
v = velocity in m/s
Answer:
KE=1/2mv^2
Explanation:
I hope this helps it's just the formula.
KE=1/2×mass×velocity^2
You want to create a space station that is 50 meters in radius. If you want it to simulate Earth's gravitation, how fast must it go?
Answer:
w = 0.196 rad / s
Explanation:
To generate an acceleration similar to that of the earth, the station's centripetal acceleration must be equal to the acceleration due to gravity.
a_c = v² / r = w² r
a_c = g
we substitute
g = w² r
w² = g / r
w = [tex]\sqrt { \frac{g}{r} }[/tex]
let's calculate
w = √9.8/50
w = 0.196 rad / s
therefore the station must rotate at that angular velocity so that the acceleration in the outer wall is equal to the ratio of gravity
Define A Gamma Ray .....---_---__☘️
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.

Circle the letter of each sentence that is true about calculating the
acceleration of a moving object.
A.) If an object is moving without changing direction, then its acceleration is the change in its speed during one unit of time.
B.) If an object's speed changes by the same amount during each unit of
time, then the acceleration of the object at any time is the same.
C.) To determine the acceleration of an object, you must calculate the
change in velocity during only one unit of time.
D.) If an object's acceleration varies, then you can describe only average
acceleration.
