The change in motion of an object is influenced by both the mass of the object and the size of the force applied to it, as per Newton's second law of motion.
Explanation:The change in motion of an object, also known as acceleration, is dictated by Newton's second law of motion. According to this law, the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. Therefore, the correct answer is A) Both the mass of the object and the size of the force. The quantity of the force applied and the mass of the object are both crucial factors that determine the change in an object's motion.

PLEASE HELP!!!!! How are energy and the amplitude of a wave related?
The higher the amplitude, the more energy the wave carries.
A wave with less energy will have a shorter wavelength.
The longer the wavelength, the greater the energy carried by a wave.
An increase in energy will result in a wave with lower amplitude.
Answer:
The higher the amplitude, the more energy the wave carries.
Explanation:
There is a direct correlation between the amplitude of a wave and its energy. The greater the amplitude, the more energy it carries compared to the same wave of lower amplitude.
The relationship of the energy and the amplitude of the wave should be that the higher the amplitude so the more energy the wave should be carried out.
Relation of energy and wave amplitude:The energy i.e. transported by the wave should be directly proportional to the amplitude square. So if any change arise in the amplitude so the square should impacts the energy. That means there is the direct relationship between the wave amplitude and the energy,
Therefore, the first option is correct.

A waitperson carrying a tray with a platter on it tips the tray at an angle of 12° below the horizontal. If the gravitational force on the platter is 5.0 N, what is the magnitude of the force parallel to the tray that tends to cause the platter to slide down the tray? (Disregard friction.)
a.
0.42 N
c.
4.9 N
b.
1.0 N
d.
5.0 N
Answer:
The answer is 1.0 N
Explanation:
inclination of tray=12^{\circ}
gravitational Force=5 N
Now this gravitational force has two component i.e.
5\sin \theta is parallel to the tray =1.039 N
5\cos \theta is perpendicular to the tray =4.890 N
The magnitude of the force parallel to the tray that tends to cause the platter to slide down is approximately 1.0 N.
Explanation:To determine the magnitude of the force parallel to the tray that tends to cause the platter to slide down, we need to find the component of the gravitational force that acts parallel to the tray. This can be done using trigonometry.
The component of the gravitational force parallel to the tray is given by the formula:
F_parallel = F_gravity * sin(theta)
Plugging in the given values:
F_parallel = 5.0 N * sin(12°)
Solving this equation, we find that the magnitude of the force parallel to the tray is approximately 1.0 N (option b).

In which situation will the lowest resistance occur?
A. thick wire and high temperature
B. thin wire and high temperature
C.thick wire and cold temperature
D.thin wire and low temperature
C. Thick wire and cold temperature.
Explanation:
The resistance of a wire is given by: R = (ρL)/A
where ρ is the resistivity of the material, L is the length of the wire, A is the cross-sectional area of the wire.
From the formula, we see that the thicker the wire, the larger A, therefore the smaller the resistivity. so, a thick wire will have lower resistivity.
Moreover, the resistance of a wire increases with the temperature. In fact, high temperatures mean more motion of the atoms/electrons inside the wire, so more resistance to the flow of current through it. Therefore, colder temperature means lower resistance.
So, the correct option is thick wire and cold temperature.
Answer:
C. Thick wire and cold temperature.

What’s is inductive reasoning?
Answer:
got this on google and got it right
Explanation:
An example of inductive logic is, "The coin I pulled from the bag is a penny. ... Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here's an example: "Harold is a grandfather. Harold is bald.
Inductive reasoning is when someone observes data, recognizes patterns within these observations, and then draws a conclusion on these observations that they found.
Let's look at an example.
A 12-oz. coke bottle exploded after an hour in the freezer.
A second 12-oz. coke bottle exploded after an hour in the freezer.
The reasoning that was used here was inductive reasoning.
Although we might want to test a few more 12-oz. coke bottles, we can tentatively conclude that all 12-oz. coke bottles will explode after an hour in the freezer.
Since were using oneservations and recognizing patterns to draw a
conclusion, our conclusion is based on inductive reasoning.

Is it possible to use the scientific method to prove the resurrection of Jesus? *Need this ASAP*
Answer:
Explanation:The resurrection of Jesus is primarily a matter of religious faith based on historical accounts documented in religious texts and scriptures. While historical evidence, such as writings from that period or archaeological findings, can offer insights into the context and plausibility of events, proving or disproving a religious belief through the scientific method isn’t feasible.
As such, attempting to use the scientific method to prove the resurrection of Jesus may not yield definitive scientific conclusions due to the nature of the event and the limitations of scientific inquiry in matters of faith and historical events. Instead, discussions about the resurrection often involve theology, historical analysis, and personal beliefs.

As the car moves from point A , to point B, and finally to point C, the total energy of the car
A. decreases from point A to point B, then increases from point B to point C
B. increases from point A to point B, then decreases from point B to point C
C. stays the same, but is converted between potential and kinetic energy
D. is lost between points B and C
Answer: C
Explanation:
Energy stays the same, but there’s more kinetic energy the less it moves and mor kinetic energy the more it moves
The conservation of energy allows us to find the correct answer for how the change in mechanical energy is:
C. stays the same, but is converted between potential and kinetic energy.
The mechanical energy of bodies is the sum of the kinetic energy due to motion and the potential energies due to the configuration of the system.
If there is not friction in the system, that is, there are no dissipative forces, the mechanical energy must be conserved at all points, this is one of the important conservation laws of physics.
When applying this theorem to the case of the car moving, the energy is converted from potential to kinetic, on the path from A to B and is transformed from kinetic to potential on the path from B to C, but the total value of the mechanical energy remains constant.
Let's analyze the different claims:
A. False. The stable energy conservation theorem that must be constant at all points.
B. False. Must be constant.
C. True. According to the analysis, the mechanical energy is constant and transforms between potential and kinetic.
D. False. As there is no friction, the energy is not lost.
In conclusion using the conservation of energy we can find the correct answer for the transformation of mechanical energy is:
C. Stays the same, but is converted between potential and kinetic energy.

How many electrons are there in the third energy level?
Answer:
18 electrons
Explanation:
The third energy level of an atom can hold up to 18 electrons, spread across the 3s, 3p, and 3d subshells.
Explanation:The third energy level of an atom can hold a maximum of 18 electrons. This is due to the existence of three possible subshells in this energy level, namely 3s, 3p, and 3d. As per the electron configuration rule, an s subshell can hold 2 electrons, a p subshell can hold 6, and a d subshell can hold 10. Consequently, the third energy level, which comprises these three subshells, can collectively accommodate up to 18 electrons (2 from the s subshell, 6 from the p subshell, and 10 from the d subshell). Keep in mind, however, that the complete filling of all these subshells in the third energy level is not applicable to all elements, but rather depends on the specific electron configuration of the atom.Learn more about third energy level here:https://brainly.com/question/21326300
