Why is the principle of periodic motion used in pendulum and quartz clocks?
[please answer fast I will mark you as the brainliest :-) ]
Answer:
A pendulum of given length always takes the same time to complete one oscillation. The time period of a pendulum of given length is constant. Thus, the periodic motion of pendulum has been used to make pendulum clocks for measuring time.

What will happen when you slide the sponges in different directions?
Transform boundary
is the answer from stemscopes
The sponges will contract when there is a slide of sponges in different directions.
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.

Four forces are exerted on each of the two objects shown below:
Which object will move in the up direction?
A : Object A but not Object B
B: Object B but not Object A
C: Both Object A and Object B
D: Neither Object A nor Object B
Answer: Object A but not Object B.
Explanation:
Answer:
A. Object A but not B
Explanation:
Because object A has the most force pulling up, 6 newtons. It has weaker forces pulling on all other sides but the upward force is the strongest
Object b will not go up because it has just as much pulling down on it as it does pulling up. Since there's 3 newtons of force pulling up and 3 pulling down it cancels out and does not move

She was rambling on in this way when she reached the wood: it looked very cool and shady. “Well, at any rate, it's a great comfort,” she said as she stepped under the trees, “after being so hot, to get into the—into WHAT?” she went on, rather surprised at not being able to think of the word. “I mean to get under the—under the—under THIS, you know!” putting her hand on the trunk of the tree. “What DOES it call itself, I wonder? I do believe it's got no name—why to be sure it hasn't!”
She stood silent for a minute, thinking: then she suddenly began again. “Then it really HAS happened, after all! And now, who am I? I WILL remember if I can! I'm determined to do it!” But being determined didn't help much, and all she could say, after a great deal of puzzling, was, “L, I KNOW it begins with L!”

The total solar energy incident on Earth is far greater than the global energy needs at the moment and in the future. This highly diffused source might potentially provide all of the energy required in the future if properly harnessed.
As the solar powered toy moved when you shines a flashlight on it, it absorbed the energy from the flashlight and light from the flashlight carried energy.

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.
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.

1.What is a non example of constant?
2.What is an example of constant?
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

Non-metals are found where on the periodic table?
A. Everywhere
B. Center
C. Lower left side
D. Upper right side
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.

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.
