what do you understand by 'weightlessness due to freefall'?
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.

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.

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.

The charge of most alkaline earth metals.
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

Sophie runs around an oval 5 mile track. What is Sophie's displacement and total distance ran?
Her displacement and distance are each 0.
Her displacement is O and her distance is 5 miles.
Her displacement is 5 miles and her distance is 0.
Her distance and displacement are each 5 miles.
Answer:
Her displacement is 0 miles and her distance is 5 miles.
Explanation:
Given information:
Sophie runs in an oval track. The length of track is 5 m.
Distance is the total length of path covered during motion while displacement is the shortest distance between initial and final position.
In this case, Sophie completes one cycle in the oval track and the track length is 5 m. So, the distance covered by her will be 5 m.
Now, after completing the track, the initial and final position of Sophie will be same and hence, the displacement she covered will be 0 miles.
Therefore, option "Her displacement is 0 mile and her distance is 5 miles" is correct.
For more details, refer the link:
https://brainly.com/question/3243551?referrer=searchResults
The displacement of Sophie is 0 and her distance is 5 m
The displacement of Sophie is the change in her position.
If she runs in an oval track, she will return to her initial starting position. The initial position and the final position will be equal, the change in her displacement will be zero.
[tex]\Delta x = x_f- x_i\\\\\Delta x = 5 - 5 = 0[/tex]
The distance traveled by Sophie is the sum of the total distance covered.
distance = 5 m
Thus, the displacement of Sophie is 0 and her distance is 5 m

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.

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.

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.

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...

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 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]
