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.
I hope this helps!

Based on your observation of the Tracker videos and the calculations of average vertical velocity and acceleration,
• Why do you think the vertical acceleration values are not equal to the theoretical acceleration due to gravity, -9.81 meters/second?
• What can you say about your earlier prediction about which ball will land first? If your hypothesis was wrong, can you propose an alternate
rationale for the observed results?
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.
1.How many significant digits are in 101,407,063?
Answer:
There are 9 significant digits in 101,407,063.
Explanation:
Significant figures are the digits of a number that are meaningful in terms of accuracy. The include any non-zero digit, zeros between non-zero digits, and trailing zeros only when there is a decimal point.
what is a mechanism?
A mechanism is what is responsible for any action or reaction. Machines are based on the idea of transmitting forces through a series of predetermined motions. These related concepts are the basis of dynamic movement.

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.

Explanation:
A bus traveling at 30 m/s accelerates at a constant rate of 2.4 m/s2 over a distance of 60 m.
What is its speed after accelerating?
Answer:
Speed is 34.5 m/s
Explanation:
From the third equation of motion:
[tex]{ \boxed{ \sf{v {}^{2} = {u}^{2} + 2as}}}[/tex]
v is final velocity, u is initial velocity, a is acceleration, s is displacement.
substitute:
[tex] {v}^{2} = {30}^{2} + (2 \times 2.4 \times 60) \\ {v}^{2} = 900 + 288 \\ {v} {}^{2} = 1188 \\ {v} = \sqrt{1188} \\ v = 34.5 \: m {s}^{ - 1} [/tex]
One equation that describes motion of an object is
x = vt + xo, where x is the position of the object, v is
its speed, t is time, and xo is the initial position. Show
that the dimensions in the equation are consistent.
We have that the resultant equation is L=L we can say that the dimensions in the equation are consistent
From the Question we are given equation
[tex]x = vt + xo[/tex]
Generally
x = distance in meters(m)
v =velocity in m/s
t=time in secs
x_0=distance in meters(m)
Therefore
The Dimension of equation is
[tex]L=LT^{-1}*T+L\\\\L=L[/tex]
Hence, Given that the resultant equation is L=L we can say that the dimensions in the equation are consistent

How can you decrease the amount of energy an object has?
Answer: Hello There!...............
You decrease the kinetic energy by either stopping the object and let it rest (which would give it potential energy) or changeing the slope.
Explanation:
Mark me brainest please. Hope this helps. Anna ♥
Depending on the sort of energy involved, you can use a variety of techniques to reduce the quantity of energy an object contains. To slow motion in mechanical systems, you can add friction or resistance, which turns kinetic energy into heat.
When dealing with thermal energy, you can place the object in a cooler environment, which will enable it to transmit heat and cool down. It is possible to lessen an object's potential energy by changing its height or location within a gravitational field. Reactions that release energy can dissipate chemical energy. These strategies essentially entail aiding energy transfer or conversion to a less energetic state, hence lowering the object's overall energy content.

Cats heart rate do not increase while napping.
The range of heart beat of a cat is 140 and 220 bpm
From the Question we are asked
Does a cat’s heart rate change while it is napping.
The answer is NO
Cats heart rate do not increase while napping. Cat have a normal heart beat maximum of 220 beats per minute consistently.The range of heart beat of a cat is 140 and 220 bpm
Therefore
There is something with a cat with heart rate above this number.
