The Metonic cycle is a period of almost exactly 19 years after which the lunar phases recur at the same time of the year.
The Metonic cycle is defined as ,235 synodic months is just 2 hours, 4 minutes and 58 seconds longer than 19 tropical years.
In Athens, at 5th century BC, give the cycle to be a whole number of days, 6,940. Using these whole numbers facilitates the construction of a lunisolar calendar.
A tropical year is longer than 12 lunar months and shorter than 13 of them. The arithmetic representation of 12×12 + 7×13 = 235 allows it to be seen that a combination of 12 "short" years (12 months) and 7 "long" years (13 months) will be almost equal to 19 solar years.

During the time that a planet is in its period of apparent retrograde motion, _________.
Answer:
The center of the retrograde motion occurs at the planet's opposition which is when it is exactly opposite the Sun.
Explanation:
The intensity of sunlight at the Earth's distance from the Sun is 1370 W/m². Assume the Earth absorbs all the sunlight incident upon it. (b) Explain how this force compares with the Sun's gravitational attraction
Comparing these two values, Fgav is much greater than Fr.
First, calculate the force produced by the radiation pressure:
The radiation pressure produces a force equal to,
Fr=pr(πRe2)
=(I/c) ( πRe2)
Given that
I= Intensity of sun = 1370 W/m²
c = speed of light = 2.998×108m/s
Re = Radius of the earth= 6.37×106m
Ms= mass of sun = 2.0×1030kg
Me= mass of earth = 5.98×1024kg
des2 = distance of earth and sun apart =1.5×1011m
Substituting the given values according to the question
Fr= π (1.37 × 103 kW/m2) (6.37×106m)2/2.998×108m/s
=6.0×108N
(b) The gravitational pull of the Sun on the Earth is,
Fgav= GMsMe/ des2
putting values according to question
Fgav= (6.67×10−11 N⋅m2/kg2) (2.0×1030kg) (5.98×1024kg) / (1.5×1011m)2
=3.6×1022N.

Electrical forces can be divided into two categories: attractive electrical forces and repellent electrical forces. Similar charges repel one another whereas opposite charges attract one another.
What is meant by electric force?The electric force attracts the nucleus and electrons to one another. The emptiness that a positive or negative charge leaves behind is known as an electric field because a field is produced there.
Electrical forces can be categorized into two groups: those that attract and those that repel. While opposite charges attract one another, similar charges repel one another.

Duration .i.e. time t = 0.1s
To find here change in velocity =?
Solution,
The impulse(J) of an object is equal to,
J = F× T
Where J is the impulse of the baseball and F is force on baseball at time t.
The impulse is equal to the change in momentum of the baseball and its unit is (N.s) Newton -second. it is a vector quantity therefore the dimension is [LMT⁻¹]. Then the impulse j is given as ,
J = m(v-u)
Here J is impulse ,m is mass, (v-u) is change in velocity .From equating the both impulse equations then can be write as,
m(v-u) = F× t
(v -u) =( F × t)/m
(v -u) = (10N× 0.1 s)/0.5k
(v -u) = 2m/s

How many protons, neutrons, and electrons are there, respectively, in an atom of o-17?.
In an atom of O-17, proton and electron is 8, and neutrons is 9.
The atomic number, sometimes referred to as nuclear charge number, of a chemical element is the charge number of an atomic nucleus. For conventional nuclei, this is comparable to the proton number, or the number of protons found in the nucleus of each atom of that element.The atomic number of oxygen is 8. Therefore, an atom needs 8 protons in order to be referred to as an oxygen atom. For instance, an atom will no longer be oxygen if it has 9 protons and will now be fluorine. Any atom that lacks 8 protons is not an oxygen atom. For an atom to be neutrally charged, the number of protons and electrons within it must match. Therefore, there should be 8 electrons in all. However, depending on the isotope, the neutron count can change. An oxygen isotope is a distinct variety of oxygen. For instance, oxygen-15, which has 7 neutrons, is a possibility. The neutron count for oxygen-16 would be 8, for oxygen-17 it would be 9, and so on.Learn more about the quantum mechanics with the help of the given link:

If an automobile gets 24.5 miles to the gallon and the cost of gasoline is $2.75 a gallon, how much will it cost to drive 975 km?
It will cost $68 to travel 975 kilometers for an automobile if the cost of gasoline is $2.75 per gallon.
This simple calculation can be explained as below calculation of the cost of driving such a distance is done by conversion of the distance into miles and multiplying such distance by $2.75.
Cost of DrivingFirst calculate the kilometers to miles.
975 kilometers is converted as 605.837 miles. Now the division of mileage of automobile will be calculated as,
Gasoline required = Distance travelled/ mileage
=605.837/24.5
=24.72 gallons of gasoline required.
Now we have to calculate the cost of gasoline.
Gasoline cost= gallons x cost per gallon
= 24.72 x 2.75
=$68
So, it is calculated that the cost of gasoline/ cost of driving is $68.0.
