Answer:
Consider electrons incident on a Young's double slit
If one slit is covered, the electrons will form a maximum, on the screen, as if they were particles incident on the screen
If both slits are open, the pattern formed on the screen will be the same as if a wave were incident on the screen, even tho electrons are slowed to the point that only 1 electron is incident on the screen at one time.
That means that the electron interferes with itself to create the interference pattern on the screen, and there is no way to determine which slit the electron went thru without destroying the interference pattern.

what can the magnetic field be used for
Answer:
the magnetic field can be used to make electricity
Explanation:
Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy

9. Liquid A has greater density than Liquid B. Which liquid will be exerting more pressure on the sides of the container?
Answer:
The depth of water near middle tube is greater so the water comes out with greater pressure from middle tube and falls farther away from the base of vessel. The depth of water near lowermost tube is the greatest so the water comes out of lowermost tube with the greatest pressure and goes farthest from the vessel.

What is F = m x a in Newton's laws of motion?
Answer:
This is Newton's second law.
Newton's second law text:
(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)
F=ma
net force = mass x acceleration

which diagram shows the correct path of light through the glass
Explanation:
When light travels from a rarer to a denser medium, it bends towards the normal. And when light travels from denser to rarer medium, it bends away from the normal. Also, from the diagram, it is clear that emergent ray will always be parallel to the incident ray.
A net force of 153 N accelerates a 22.0 kg mass. What is the resulting acceleration?
The resulting acceleration is 6.95 m/s².
Net force (F) = 153 N
Mass (m) = 22.0 kg
To find the resulting acceleration (a), we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The equation can be written as:
F = m * a
Rearranging the equation, we have:
a = F / m
Substituting the given values, we get:
a = 153 N / 22.0 kg
Evaluating the expression, we find:
a ≈ 6.95 m/s²
Therefore, the resulting acceleration is approximately 6.95 m/s².

determine the number of significant figures in 00.6022009
The number of significant figures in 00.6022009 is 7 .
The number of significant figures is 7.
Explanation:
Significant figures
The figures in a number that expresses the magnitude of a quantity to a specific degree of accuracy are known as significant digits.Digits from 1 to 9 are always significant and have an infinite number of significant figures.All non-zero numbers are always significant. For example, 684, 9.54, and 63.4 all have three significant figures.All zero’s between integers are always significant. For example, 2005, 8.005, and 10.05 all have four significant figures.All zero’s preceding the first integers are not significant. For example, 0.0038 has two significant figures.All zero’s after the decimal point are always significant. For example, 4.500, 43.00, and 950.0 all have four significant figures.All zeroes used solely for spacing the decimal point are not significant. For example, 6000 has one significant figure.Given :
The number 00.6022009
To find:
The number of significant figures in the number.
Solution
00.6022009
All zero’s preceding the first integers are not significant.

1. The atomic number of an element is the same as the number of ______ that the element has.
Answer:
Explanation:
The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers.

Some students collect some drops of water from a leaking tap.
The students measure the volume of the water they collect.
State the term for the equipment that is suitable for measuring the volume accurately.
Explanation:
The concept of temperature has evolved from the common concepts of hot and cold. Human perception of what feels hot or cold is a relative one. For example, if you place one hand in hot water and the other in cold water, and then place both hands in tepid water, the tepid water will feel cool to the hand that was in hot water, and warm to the one that was in cold water. The scientific definition of temperature is less ambiguous than your senses of hot and cold. Temperature is operationally defined to be what we measure with a thermometer. (Many physical quantities are defined solely in terms of how they are measured. We shall see later how temperature is related to the kinetic energies of atoms and molecules, a more physical explanation.) Two accurate thermometers, one placed in hot water and the other in cold water, will show the hot water to have a higher temperature. If they are then placed in the tepid water, both will give identical readings (within measurement uncertainties). In this section, we discuss temperature, its measurement by thermometers, and its relationship to thermal equilibrium. Again, temperature is the quantity measured by a thermometer.

How does the distance traveled by the coin compare to its displacement after ten flips?
Answer:
To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.
