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).

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.

When a roller coaster goes in an upside-down loop, which of the following is true?
A: the force reasonable for circular motion is acting toward the middle of the loop.
B:the force reasonable for circular motion is a ting all the way to the ground.
C: the force reasonable for circular motion is acting toward the top of the loop.
D: no force is acting on the roller coaster.
Answer:
The force responsible for circular motion is acting toward the middle of the loop.
Explanation:
When a roller coaster goes in an upside-down loop, the force responsible for circular motion is acting toward the middle of the loop. The correct option is A.
When a roller coaster rides through an upside-down loop, the force that causes circular motion acts towards the centre of the loop.
This force is known as the centripetal force, and it operates perpendicular to the roller coaster's velocity at each point of the loop.
To keep the roller coaster travelling in a curved course and from flying off the track, centripetal force is required.
The centripetal force pushes the roller coaster inward as it enters the loop, providing the necessary acceleration to maintain its round track.
This force keeps the roller coaster safely on the track and gives passengers the exhilarating sensation of being inverted.
Thus, the correct option is A.

How is frequency related to time period
Answer:
mark brainliest :)
Explanation:
Frequency and period are inversely related quantities. Frequency refers to how often something happens; whereas Period refers to the time it takes for something to happen. ... Frequency is the number of cycles/second denoted as Hertz (Hz). Period is the seconds/cycle.
Explanation:
Relation between frequency (f) and time period(T)
By the definition of frequency,
f vibrations are completed in one second
Or 1 vibration is completed in 1/f second
But, time to complete one vibration is its time period (T)
[tex]therefore \: \: \: t = \frac{1}{f} [/tex]

Two events in space are described below.
Event 1: The moon moves into the shadow of Earth at night and this makes it difficult to see the moon from Earth.
Event 2: The moon comes between the sun and Earth, but the moon only covers the center of the sun's disk and the sun's circular edge is visible.
Which event or events represent(s) a total solar eclipse on Earth?
Group of answer choices
Only Event 1
Only Event 2
Both Event 1 and Event 2
Neither Event 1 nor Event 2
Answer: Neither Event 1 nor Event 2
Explanation:
Let's begin by explaining when a total solar eclipse occurs:
A total solar eclipse occurs when "the Moon hides the Sun" (as seen from Earth).
So, in order to make this situation posible, the Sun, Moon, and Earth must be aligned in the plane of the ecliptic; and Moon must be in the New Moon phase. When this happens, the Moon completely covers the solar disk.
Hence, according to his explanation, Neither Event 1 nor Event 2 describe a Total Solar Eclipse, since Event 1 is not related to a solar eclipse and Event 2 describes an annular solar eclipse on Earth.
In which situation is the gravitational force between two objects hard to detect?
A. if the mass of one of the objects is very great
B. if the mass of both objects is very great
C. if the objects are very close together
D. if the mass of each object is very small
Reset
Submit
Answer:
D.
Explanation:
Newton's Law of Gravitation states that:
[tex]F_G = \frac{-Gm_1m_2}{r^2}[/tex]
If the masses of each object is small, then [tex]m_1*m_2[/tex] would be very small, making the gravitational force between the two objects hard to detect - as it itself would be very small.
Answer&Explanation:
According to the Newton gravitational law is directly proportional to the Product between masses and inversely proportional to the square of the distance..
Hence from the law and corresponding question the correct answer is D:if the mass of each object is very small
Thus it would make it undetectable

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

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.
