The repetition of the experiment allows to support the results, therefore the correct answer is:
based on experimental evidence
The theory is a set of rules, principles and knowledge that are developed from models and experiments that are carried out repeatedly, finding similar results in any given case.
In this case, Ellie repeated each experiment several times, finding results that lead to the result that the two balls hit the ground at the same time, therefore her conclusions are supported by experimental evidence.
In conclusion the conclusions of the experiment of dropping the balls the correct answer is: it is based on the experimental evidence

HELP ME!!! Explain why an object moves if the action-reaction forces are equal.
Answer:
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.

Why are there only two elements in the first period of the periodic table?(1 point)
because the first two elements both start with H and are grouped together
because the next elements have other things in common and they need to be arranged together
because only two electrons can fit in the first orbit around the nucleus, and each period on the table is organized by number of orbits
because each row increases in atomic mass by a specific number, so anything over five is in the second row

If an object is projected horizontally from a height of 5 m with an initial velocity of 7 m/s, what is the value of x^0?
x0=−9.8 m/s2
x subscript 0 baseline equals negative 9.8 m per s squared
x0=0
x subscript 0 baseline equals 0
x0=5
x subscript 0 baseline equals 5
x0=7
The horizontal displacement (x₀) of the object is 7 m.
The given parameters;
height of the object projection, h = 5 minitial horizontal velocity of the object, uₓ = 7 m/sThe vertical displacement equation of the object is given as;
h = vt + ¹/₂gt²
where;
v is the initial vertical velocity = 0
The time of motion is calculated as;
5 = 0 + (0.5 x 9.8)t²
5 = 4.9t²
[tex]t^2 = \frac{5}{4.9} \\\\t^2 = 1.02\\\\t = \sqrt{1.02} \\\\t = 1 \ s[/tex]
The horizontal displacement of the object is calculated as;
X₀ = uₓt
X₀ = 7 x 1
X₀ = 7 m
Thus, the horizontal displacement (x₀) of the object is 7 m.

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.

Which of the following statement is correct
The density of an object does not remains same if we take small quantity of that substance.
The density of an object remains same irrespective of its shape, size and quantity.
The density of an object does not remains same irrespective of its shape and size.
The density of an object remains same only if its shape and size remains same.
The density of an object remains same irrespective of its shape, size and quantity.
Explanation:
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.

Conversion of mass from grams into kg :
[tex]1kg = 1000g[/tex][tex]1g = \dfrac{1}{1000} \: kg[/tex][tex]200g = \dfrac{200}{1000} \: kg[/tex][tex]200g = 0.2kg[/tex]1. A car weighs 1000kg, you can push it .05 m/s2, how much force (F) are you applying
to the car? Here we use F=MA:
F= 1000 x .05
F= 50 newtons
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.
if you know the time it took an object to travel between two points and the position of the object at the points, can you determine the object's instantaneous velocity
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]
What is Velocity?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.

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

If you touch the two probes together while the DMM is set to resistance, what will happen?
The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery
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.
