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?

A ball with a mass of .012 kg moving at 15.0 m/s collides with a second ball with a mass of 36 g
moving at 5.0 m/s. After the collision, the 12 g ball moves in the same direction at 6.0 m/s. What
is the resulting velocity of the 36 g ball????
Answer:
Solve:
1/2(.5)(36)+1/2(1)(144)=
1/2(.5)(196)+1/2(1)(x^2)
9+72=49+.5x^2
81=49+.5x^2
32=.5x^2
64=x^2
x=8 m/s
Thus, the speed of the second ball after the collision is 8 m/s.
Hope this helps! Good luck!

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
Describe the components of the universe.
3-4 sentences
Answer:
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Explanation:
Answer:
Hey mate....
Explanation:
This is ur answer.....
According the NASA's StarChild Website, "The universe is a vast open space which contains all of the matter and energy in existence. The universe contains all of the galaxies, nebulae, stars, and planets. The exact size of the universe is unknown. Scientists believe the universe is still expanding outward.
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

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.
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

The abbreviation for the SI unit for electric potential is V.
What is Electric potential?This is defined as the amount of work energy needed to move a unit of electric charge from one point to another in an electric field.
Electric potential = Energy/ Charge
The unit of electric potential is either Joules per coulomb or Volts(V) which makes option A the most appropriate choice.

What types of changes in motion cause acceleration?
Answer:
Change in velocity and direction over a specific period of time.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate the acceleration of an object.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Hence, the types of changes in motion that cause acceleration is a change in velocity and direction over a specific period of time.
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.

In 3-4 sentences, briefly summarize how our solar system formed.
Answer:
Explanation:
Our solar system is formed by a dust storm, which created the planets. This info is grabbed by NASA, and people believe this is how the Solar System is formed. The sun is formed like this too.
Answer:
Well a lot of people believes in evolution. But in fact evolution is actually clearly impossible because how can dead which is Non-Living bacteria and dirt make something alive like living. And anyway there's a lot of thing's in nature that shows there is a creator. Like how does bees know when there honey comb is to warm to start fanning there wings to cool the honey comb down? And like human beings for example we didn't generate from aps. Yes there smart like us and sorta human like but the way our bodies are designed is wayyyyy to complicated. For example our brain its a computer we dont shut it on and off it's always running constantly and we dont have to worry about turning our brain on or off. I know this wasent what u have asked but i made me think about it and also someone created the universe because the whole universe hangs on nothing but they stay aligned. So this shows that there is a creator though.
