A piece of unknown metal with mass 68.6 g is heated to an initial temperature of 100 °C and dropped into 42 g of water (with an initial temperature of 20 °C) in a calorimeter. The final temperature of the system is 52.1°C. The specific heat of water is 4.184 J/g*⁰C. What is the specific heat of the metal?Identify a potential source of error that may have occurred during the calorimetry experiment. Justify your response in two or more complete sentences.
Answers
According to the mass of the metal and the temperature it should be under the average heat of water which is 4.184 but also above it, which brings us back to how much it dropped which means that it goes back and going half way.

A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s tectonic plates. He asks his students to explain how this occurred. Which student’s explanation is best?
Student A
An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student B
A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student C
An oceanic plate converged with a continental plate. The more dense, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

1.What is a non example of constant?
2.What is an example of constant?
Answers
Answer:
1. A non example of a constant in physics is a value that changes. For example, the temperature of Hong Kong, let's say, is not a constant, since it changes and does not stay at the same value. It gets higher in the summer and lower in the winter.
2. An example of a constant in physics would be the gravitational acceleration of the Earth. Since the Earth's mass' changes is negligible when compared with the overall mass of the Earth (unless something big happens, of course, like a meteor or asteroid), the gravitational acceleration on Earth is largely unchanged, even constant from our viewpoint.
Explanation:
Hope this helped!
Answer:
a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant. a dependant variable(opposite)would be the properties of the plants themselves, which the scientist is observing in relation to the changing light. These properties might include the plants' color, height and general health of the plant

A car engine uses the combustion of fuel to move a system of gears that
move its wheels. Not all of the fuel's energy is transferred to the wheels.
Which two transformations happen to the rest of the energy?
I A. It is transformed into sound energy.
O B. It is transformed into thermal energy.
I c. It is transformed into chemical energy.
D. It is transformed into nuclear energy.
E. It is transformed into kinetic energy.
Answers
Answer:
A and B
Explanation:
When a car engine uses the combustion of fuel to move a system of gears that move its wheels, the fuel's energy is transferred to the wheels and the rest of the energy: is transformed into sound energy and thermal energy. So, option (A) and (B) are correct.
What is law of conservation of energy?Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms.
In a nutshell, the law of conservation of energy asserts that the system's total energy is conserved in closed systems, or systems that are separated from their environment.
When car engine uses the combustion of fuel to move a system of gears that move its wheels, maximum of its energy transformed into kinetic energy and rest of energy is dissipated in a form of sound energy and thermal energy. So, option (A) and (B) are correct.

“That would never do, I'm sure,” said Alice: “the governess would never think of excusing me lessons for that. If she couldn't remember my name, she'd call me ‘Miss!’ as the servants do.”
“Well, if she said ‘Miss,’ and didn't say anything more,” the Gnat remarked, “of course you'd miss your lessons. That's a joke. I wish YOU had made it.”
“Why do you wish I had made it?” Alice asked. “It's a very bad one.”
But the Gnat only sighed deeply, while two large tears came rolling down its cheeks.
“You shouldn't make jokes,” Alice said, “if it makes you so unhappy.”
Then came another of those melancholy little sighs, and this time the poor Gnat really seemed to have sighed itself away, for, when Alice looked up, there was nothing whatever to be seen on the twig, and, as she was getting quite chilly with sitting still so long, she got up and walked on.

What are the sponges?Sponges are called as the members of the phylum Porifera. This is a basic animal group and the diploblasts' sibling. They are multicellular creatures with pores and channels that let water to move through their bodies, which are made of jelly-like mesohyl sandwiched between two thin layers of cells.
Sea sponges were among the earliest animal groups to form on Earth, but new chemical evidence puts their appearance 120 million years earlier than previously assumed, according to New Scientist.
According to the research, it is found that When there is a sliding of sponges in opposite directions, the sponges will compress. As water filters through the porous shell of a sponge, it develops motion, obtains food and oxygen, and expel waste.
Therefore, Flagella, microscopic hairlike structures inside the sponge, produce currents that filter germs out of the sponge's cells and trap food within them.

Amy has a mass of 30 kg, and she is riding a skateboard traveling 5 meters per second.
What is her momentum?
5 kg⋅m/s
6 kg⋅m/s
30 kg⋅m/s
150 kg⋅m/s
Answers
Answer:
A is correct
Explanation:
Momentum is the product of mass and velocity of the moving object. The momentum of Amy weighing 30 Kg riding with 5 m/s is 150 Kg m/s.
What is momentum?Momentum is a physical quantity measuring the product of mass and velocity of a body. There are both linear momentum and angular momentum. Angular momentum is the momentum associated with a rotating body.
Momentum of a body increases with increase in mass and velocity.
The mass of the girl is given 30 Kg riding with a velocity of 5 m/s. Thus her momentum can be calculated as:
p = m v
= 30 Kg × 5 m/s
= 150 kg m/s.
Therefore, the momentum of Amy is 150 Kg m/s.

Answers
A. physical
D. Upper right
Answer:
1.) A, a physical change
2.) D, Upper right side
Explanation:
1.) Changing states does not atomically change the chemical build up of any object. Water is still water whether as liquid H2O, ice, or water vapor. Since it is only changing how an object looks and not the chemically make up, melting and freezing constitutes as physical changes
2.) Non-metals are elements that do no share the traits and characteristics of a metal. Most non-metals classify as a gas. This includes : helium, hydrogen, oxygen, carbon, nitrogen, and sulfur just to name a few.
Where are all these elements found on the table? The right sides of the periodic table.
what is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?
Answers
Well, "speed" normally = (total distance covered) / (time to cover the distance).
In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".
Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...
Speed of visits = (total houses visited) / (time to visit them).
Speed of visits = (800 million houses) / (48 hours)
Speed of visits = 16.67 million houses per hour.
That's 277.8 thousand houses per minute
That's 4,630 houses per second
