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.

explanation is below

Explanation:

Equal and opposing forces acting on the same object are referred to as balanced forces. That is why they cancel each other out. Action-reaction forces do not cancel out because they are equal and opposite forces acting on different objects. In fact, they frequently cause movement.

Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

Answer:

Yes

Explanation:

[tex]v = \frac{ds}{dt} \\ where \: we \: need \: to \: know \\ \: change \: in \: displacement \\ \: and \: the \: time \: taken[/tex]

if you know the time it took an object to travel between two points and the position of the object at the points, then we can determine the object's instantaneous velocity by using the differential rate of the displacement function with respect to the time.

Instantaneous velocity =  [tex]\frac{dS}{dt}[/tex]

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

velocity= displacement  / time taken

for instantaneous velocity =  [tex]\frac{dS}{dt}[/tex]

Thus, If you know how long it took an item to go between two places and where it was when it got there, you can use the differential rate of the displacement function with respect to time to calculate the object's instantaneous velocity.

Mass of the car (m) = 1000 Kg

Acceleration (a) = 0.05 m/s^2

Let the force we are applying to the car be F N.

By using the equation,

F = ma, we get

F = 1000×0.05 N = 50 N

Answer: We are applying 50 N force to the car in the direction of motion.

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.

Answer:

2+ charge

Explanation:  The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge

Answer:

Weightlessness is simply a sensation experienced by an individual when there are no external objects touching one's body and exerting a push or pull upon it.

Answer:

Weightlessness is simply a sensation experienced by an individual when there are no external objects touching one's body and exerting a push or pull upon it. ... When in free fall, the only force acting upon your body is the force of gravity - a non-contact force.

Insulation helps to prevent that transfer of heat.

Answer: I think the vertical acceleration values are not equal to the theoretical acceleration due to gravity, -9.81 meters/second2 due to the gravity force and maybe the drag due to air resistance.

Explanation: About my earlier prediction about which ball will land first, I can say that my hypothesis was right, but not quite because I calculated the average vertical acceleration, where the time period is t = 0.10 second to t = 1.00 second, the results were different. If the result were maybe right or close to the I would have said that my hypothesis was correct.

H² = B² × L²

H² = (9.2)² × (5.2)²

H² = 84.64 × 27.04

H² = 2288.6656

H = √ 2288.6656

H = 47.84

Answer:

Use Pythagorean theorem

19) A² + B² = C²

5.2² + 9.2² = C²

C = √111.68

C = 10.567875...

C ≈ 10.6

21) A² + B² = C²

B² = C² - A²

B² = 7.2² - 5.3²

B = √23.75

B = 4.873397...

B ≈ 4.9

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.

If the meter's battery is good and the meter is working OK, it should read zero ohms.

Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.
