When would the temperature and thermal energy of an object differ?
The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.
Any beaker to measure the volume of liquid displaced
SIZE AND DISTANCE BETWEEN THEM
Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.The lysosomes are the animal cell's "garbage disposal", while in plant cells the same function takes place in vacuoles.Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

I just took the quiz and the answer is D.)wind flow and temperature
There are 2 ways of solving this question
First is to use formula which connects starting speed, acceleration (which we would calculate from graph where we can see how speed changes) and time to calculate traveled distance.
S = V0 * t + 1/2*a*t^2
acceleration a is a = -4m/s^2
S(t=3s) = 18
On this value we add 12 initial meters of distance and we get S(t=3s) = 30 meters
For t=4s we get
S = 16 m
Plus initial distance of 12 m we get 30 meters
Answers are 30 and 28 meters.
second way is to find surface of graph bellow speed line for 3 and 4 seconds...
Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy
Please help! Find the tension in each cord in the figure if the weight of the suspended object is w = 210N A) Find the tension in the cord A for system (b). B) Find the tension in the cord B for system (b).
- T a * cos 60° + T b * sin 45° - 210 N = 0
- T a * sin 60° + Tb cos 45° = 0
- 1/2 T a + √2 / 2 T b = 210 N
- √3 / 2 T a + √ 2 / 2 T b = 0 / * ( - 1 )
- 1/2 T a + √2 / 2 T b = 210 N
√ 3 / 2 T a - √2 / 2 T b = 0
T a ( √3 / 2 - 1 / 2 ) = 210 N
0.366 T a = 210 N
T a = 210 N : 0.366
1 ) T a = 573.77 N
Ta * √3 / 2 = T b * √ 2 / 2
T b = ( 573.77 * 1.732 ) : 1.4142
2 ) T b = 702.7 N
All of the following are possible sources of error in a scientific investigation except for A. Measuring the change in temperature incorrectly B. Manipulating the wrong variables in the experiment C. Reviewing previously published studies before the experiment D. Completing only one trial in the experiment
Your answer would be C my friend
Earth's core is composed of two separate layers the inner core and the outer core what is one difference between these two layers? F. One is orphans one is zinc G. One is liquid and one is gas H. One is solid and one is liquid I. One is iron and one is nickel
Which statement is NOT true? a. water plays an important role in the control of body temperature b. water helps carry nutrients to cells and waste products away from cells c. people need a minimum of 10-12 glasses of water each day d. soups, fruits, vegetables, and meats are sources of water
Lina is late to science class and misses the very beginning of notes for the day. These are the notes that Lina did copy down: –Found within galaxies –Have at least 1 star at the center –Have objects orbiting the star –Planets –Moons –Asteroids, comets, meteoroids, dwarf planets Lina later copied the title of the notes from a friend. What title did Lina most likely copy?
hope this helps you
Axons on the other hand transmit information from the cell body to other neurons or to cells in glands and muscles. This would make a bit more sense if you take a look at a structure of the neuron.
What information does the atomic mass of an element provide? A. the sum of electrons and protons in an atom B. the difference between the number of protons and electrons C. the number of protons and neutrons in an atom D. the number of isotopes
The atomic mass is the sum of the number of neutrons and protons.
What happens when the electron moves from the first energy level to the second energy level? Energy is absorbed, and an emission line is produced. Energy is released, and an emission line is produced. Energy is absorbed by the atom. Energy is lost from the atom.
Emission lines occur only in the case of transitions from higher to lower energy levels in which energy is emitted.
What causes the electric charges to flow from one end of the battery to the other? a balance in electric potential a balance in resistance a difference in electric potential a difference in resistance
PLEASE HELP FAST??!! Which statement is true about the electromagnetic spectrum? A. The visible Spectrum includes radio waves, light and gamma rays. B.

The waves travel at a speed of 2.998 *10^5 m/s
The electromagnetic spectrum contains visible light along with many other components such as radio waves, microwaves, ultraviolet rays and gamma rays.
The water has potential energy when it is at the top of the falls which is converted into kinetic energy as it falls.
Which of the following is true of both nuclear fusion and nuclear fission? a. They both require a high energy input. b. They both occur without byproducts. c. They both have a high energy output. d. They both involve large atoms breaking into smaller atoms.
Both processes release tremendous amounts of energy.
