Potential energy : energy obtained due to height or position (the force of gravity)
PE = mhg
g = acceleration due to gravity (m/s²)
h = height (m)
m = mass (kg)
1. Known
m = 0.5 kg
h = 1 m
g = 9.8 m/s²
then :
[tex]\tt PE=0.5\times 1\times 9.8=4.9~J[/tex]
Kinetic energy is the energy gained by an object's motion
KE = 1/2 mv²
2. To find KE, the required data are the mass and velocity
in this table, you do not display the velocity

Read the following excerpt and answer the question:
Scientists often refer to mushrooms as the "dark matter of biology" because we don't know much about them. Mushrooms are not plants
because they have no chlorophyll and cannot make their own food. They are actually fungi and absorb nutrients from their surrounding
environments, and they can even thrive at the bottom of the ocean or in the middle of a desert!
Use your own words to summarize why mushrooms and plants differ in their needs to use radiant energy from the sun.
Answer:
\/
Explanation:
Plants rely directly on the energy from the sun. The chloroplast create glucose from the sun rays through a process known as photosynthesis. Mushrooms, on the other hand, do not have the ability to use the sun's rays to create food, so they instead gather their energy from the nutrients from the soil or decaying things, such as plants, that once used the sun's radiation as sustenance. So basically mushrooms use the radiant energy from the sun indirectly and plants use it directly

HELP ME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
A nonmetal
Explanation:
please answer it ??
Answer:
A is √34
Explanation:
We can solve for the hypotenuse "A" using the Pythagorean theorem.
a²+b²=c²
3²+5²=c²
9+25=c²
34=c²
√c=√34
c=√34 --> A

What word is used to describe the electrodes used in electrolysis that do not react?
Answer:
Electrodes are the rods that carry the electric current to and from the electrolyte. These rods are usually inert, as in they do not react- usually graphite or platinum. The positive electrode is called the anode and the negative electrode is called the cathode.
Explanation:
plz mark me as brainiest
Electrodes in electrolysis that do not react are called inert electrodes.
Electrodes are conductors which carry current in and out of the electrolyte.
The negative electrode is the anode and the positive electrode is the cathode.
Inert electrodes do not react.
Electrodes in electrolysis that do not react are called inert electrodes.

a suspension is said to be. unstable why. old fast I will mark brainly
Answer with Explanation:
A "suspension" is said to be unstable because some of its particles settle at the bottom when it is left for some time. One example of this is the "antibiotic suspension." If you might have noticed, the particles settle at the bottom and this is the reason why it is important to shake the medicine before giving it to patients. Another point to consider is the fact that the suspension has a residue when you try to filter out the particles. This means the solute can be separated from the solvent; thus, it cannot be distributed uniformly. So, this makes it unstable.

If a molecule of CH4 diffuses a distance of 0.530 m from a point source, calculate the distance (meters) that a molecule of N2 would diffuse under the same conditions for the same period of time (1 second).
Explanation:
Assume the gases each diffuse in one second, in order to create a rate.
Set rate1 = N2 = x
Set rate2 = CH4 = 0.530 m/sThe molecular weight of N2 = 28.0
The molecular weight of CH4 = 16.0
Graham's Law is:
r1 over r2 = √MM2 over √MM1
Substituting, we have:
x / 0.530 = √(16.0 / 28.0)x = 0.400 m/s
how to know that something is a basic oxide or acedic oxides?
plz help
Explanation:
General Rules. In general, the electropositive character of the oxide's central atom will determne whether the oxide will be acidic or basic. The more electropositive the central atom the more basic the oxide. The more electronegative the central atom, the more acidic the oxide.
what part of the atom canot have its part acuratly determined ill give brainlest hurry
Answer:
The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.
Explanation:
A positively charged object is placed a short distance from a negatively charged object.
What would happen to the objects if the distance between them doubled?
The objects would -
A)attract each other and the force would decrease
B)repel each other and the force would decrease
C)attract each other and the force would increase
D)repel each other and the force would increase
Answer: attract eachother and the force would decrease
Explanation:
A sample of iron has a volume of 12 mL. If the mass of this object is 94 g, what is the density of iron? Will it sink or float in water? *
Answer:
density = 7.83g/mL
It will sink in water.
Explanation:
D = mass/volume
94/12 = 7.83 g/mL
density of water is 1g/mL
Object is more dense than water, meaning it will sink.
Which characteristics of Earth’s surface can be determined by using a topographic map?

_________energy is stored in chemical bonds.
Answer:
Chemical energy is the potential energy stored in the arrangement of atoms within molecules. Breaking chemical bonds requires energy, while forming new chemical bonds releases energy. The more energy that's released when a bond forms, the more stable that bond is.

distance = speed × timeFrom the question
speed = 2 m/s
time = 60 s

The Tropical Zone experiences Tradewinds. True or false?
Answer:
It is true , that the tropical zone experiences the trade winds .
Explanation:
TRADE WINDS -: The trade winds or easterlies are the dominant east-to - west permanent winds that flow in the equatorial area of the Planet (between latitudes 30 ° N and 30 ° S). In the Northern Hemisphere, the trade winds blow primarily from the northeast and from the southeast in the Southern Hemisphere, strengthening throughout the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by sailing ship captains for centuries to cross the world's oceans and have enabled colonial expansion into the Americas and the construction of trade routes across the Atlantic and Pacific oceans. They act as the steering flow for tropical storms in meteorology. developing over the Atlantic , Pacific, and Southern Indian Oceans and landing in North America, Southeast Asia, Madagascar, and East Africa. Under trade wind regimes, shallow cumulus clouds are seen and are capped from being larger by a trade wind inversion induced by downward air aloft from within the subtropical ridge.
When trade winds blow through tropical areas , due to more direct sunlight , air masses heat up across lower latitudes. Those that develop over (continental) land are drier and hotter than those that develop over (maritime) oceans and travel northward to the subtropical ridge 's western periphery. Masses of maritime tropical air are often referred to as masses of commercial air. There are extensive areas of trade winds in all tropical oceans except the northern Indian Ocean.
Hence , the statement is true.
