Mechanical energy s the TOTAL potential energy and kinetic energy in an object. TRUE OR FALSE???
Answer:
TRUE
Explanation:
The mechanical energy of an object can be the result of its motion and/or the result of its stored energy of position.
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.

A solar powered toy moved when you shines a flashlight on it. this is explained by:
light from the flashlight carried energy.energy from the flashlight was absorbed by the toy.What is solar energy?Solar energy is the radiation that the Sun emits that has the ability to create heat, trigger chemical reactions, or create electricity. 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.Compare how waves are used to send information.
2. Describe methods of communication.
3. Identify modern methods of communication.
Answer:
1:Radio waves are used to carry satellite signals. These waves travel at 300,000 km/s (the speed of light).
2:The standard methods of communication are speaking or writing by a sender and listening or reading the receiver. Most communication is oral, with one party speaking and others listening. ... A mixed message occurs when a person's words communicate one message, while nonverbally, he or she is communicating something else.
3: Today means of communication has increased such a lot that we can receive or send messages from or to far off places. Various means of communication which we use in the modern world are Posts and Telegraphs, Telephone, Radio and Television, Telex, Fax, Pagers, Email, Newspapers and cinema.
Objects too far away from the Sun do not orbit it. Explain why this occurs.
Answer:
The Sun's gravitational pull is not as strong as objects get farther away
Explanation:
Answer:
The answer would probably be gravitational pull
Explanation:
The farther an object is from the sun and the slower it will orbit the sun. If an object is closer from an other star than to the sun, or the field of attraction of this star is stronger than the one of the sun, this object will not orbit the sun at all.

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

Redox reaction is the oxidation of iron, which forms iron oxide, also known as rust. This reaction can be symbolized with the following equation: 2Fe + 3O2 forms Fe2O3. Notice the iron atoms and oxygen molecules combine to form a new compound, which makes this reaction a chemical change.
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.
