so, 444 eggs would have been released in 37yrs

If a woman releases one egg every month for 37 years, then she releases 444 eggs.

A year is a unit of time that is commonly used to measure the period of time it takes for the Earth to make one revolution around the Sun.

The time it takes for the Earth to complete one orbit around the Sun is approximately 365.24 days, which is why a year is usually defined as 365 days, with an extra day added every four years (in what's called a leap year) to account for the fractional part of the year. This is known as the Gregorian calendar, which is the most widely used calendar system in the world.

A year is also commonly used to refer to the period of time it takes for an event or cycle to repeat, such as the school year, fiscal year, or a company's financial year.

There are 12 months in a year, and they are:

January

February

March

April

May

June

July

August

September

October

November

December

Each month has either 30 or 31 days, except for February which has 28 days (or 29 days in a leap year). The number of days in a month determines the number of days in a year, which is why a year typically has either 365 or 366 days, depending on whether or not it is a leap year.

Here in the question,

37 years is equivalent to 37 x 12 = 444 months (since there are 12 months in a year).

To calculate this, we simply multiply the number of eggs released each month (which is one) by the total number of months:

Number of eggs released = 1 egg/month x 444 months

Number of eggs released = 444 eggs

Therefore, over 37 years, a woman releases 444 eggs.

Answer:

False

Explanation:

Larger pulse with more energy means that the wave has large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels

Answer:

False

Explanation:

The amplitude of a wave does not affect the speed at which the wave travels.  The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

Answer:

the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.

Explanation:

When the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.

Changes can occur that the gliders unite and move with a cosecant speed less than the initial one.

Answer:

.1 seconds per meter

Explanation:

I am going to assume they are asking for the average time per 1 meter.

Because it took 10.23 seconds to run 100 meters, we are going to divide 10.23 by 100. This number will be the time per 1 meter.

To divide by 100, we will move the decimal point over by two. That will give us .1023 seconds.

The question asks to round to the nearest tenth, so we round it to .1 seconds.

*Just some trivia: Danie van Blerk does in fact have a time of 10.23 seconds. He has the 1073rd best 100 meter dash time. First place, Usain Bolt, has a time of 9.58 seconds.

With the use of wave speed formula, below are the answers to the questions

1. C

2. C

3. D

4. B

All the question centered on wave speed, wavelength and wave frequency. The relationship between these three quantities is;

wave speed = wavelength x frequency

That is,

V = Fλ

1. The given parameters are;

V = 1,500 m/s

F = 5 Hz

wavelength λ = V/F = 1500/5 = 300 m

2.) Given that the wavelengths ranging from 2.75 to 16.5 meters and the speed of sound is approximately 330 m/s

When wavelength = 2.75 m

F = V/ λ = 330 / 2.75 = 120 Hz

When wavelength = 16.5 m

F = V/ λ = 330 / 16.5 = 20 Hz

Therefore, the frequencies of thunder humans hear ranges from 20 Hz to 120 Hz

3.) Since the two waves are similar, they will be travelling at the same speed. That is,

Wave speed of X = Wave speed of Y

For wave X and Y respectively;

F = 200 Hz and 700 Hz

λ = 35 m and λm

Find λ of Y by equating the two wave speed. That is,

Fλ for X = Fλ for Y

200 x 35 = 700 λ

λ = (200 x 35)/ 700

λ = 7000 / 700

λ = 10 m

Therefore, The wavelength for wave Y is 10 m

4.) Given that the sea lions  frequencies are ranging from 500 to 4,000 hertz. And the speed of sound in sea water is approximately 1,500 m/s

By using the same formula,

V = Fλ

Make wavelength the subject of formula

λ = V / F

When F = 500 Hz

λ  = 1500/500 = 3 m

When F = 4000 Hz

λ =  1500/4000 = 0.375 m

Therefore,  the approximate wavelengths of sound with which the California sea lions communicate is of the range 0.375 m to 3 m

Balanced Forces

But what exactly is meant by the phrase unbalanced force? What is an unbalanced force? In pursuit of an answer, we will first consider a physics book at rest on a tabletop. There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.

Consider another example involving balanced forces - a person standing on the floor. There are two forces acting upon the person. The force of gravity exerts a downward force. The floor exerts an upward force.

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The person is at equilibrium. There is no unbalanced force acting upon the person and thus the person maintains its state of motion.

Unbalanced Forces

Now consider a book sliding from left to right across a tabletop. Sometime in the prior history of the book, it may have been given a shove and set in motion from a rest position. Or perhaps it acquired its motion by sliding down an incline from an elevated position. Whatever the case, our focus is not upon the history of the book but rather upon the current situation of a book sliding to the right across a tabletop. The book is in motion and at the moment there is no one pushing it to the right. (Remember: a force is not needed to keep a moving object moving to the right.) The forces acting upon the book are shown below.

The force of gravity pulling downward and the force of the table pushing upwards on the book are of equal magnitude and opposite directions. These two forces balance each other. Yet there is no force present to balance the force of friction. As the book moves to the right, friction acts to the left to slow the book down. There is an unbalanced force; and as such, the book changes its state of motion. The book is not at equilibrium and subsequently accelerates. Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down.

To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Answer:

(a) 150 N

(b) 15.62 N

(c) 8.54 N

(d) 50 N

Explanation:

From the question above,

(a) F' = F₂-F₁

Where F' = Result force, F₁ = 50 N, F₂ = 200 N

Therefore,

F' = 200-50

F' = 150 N

(b) F' = √(F₁²+F₂²)

Where F₁ = 10 N, F₂ =12 N

F' = √(10²+12²)

F' = √(100+144)

F '= √(244)

F =15.62 N

(c)

F' = √[(F₁+F₂)²+F₃²]

Where F₁ = 6 N, F₂ = 2 N, F₃ = 3 N.

Therefore,

F' = √[(6+2)²+3²)

F' = √(8²+3²)

F' = √(64+9)

F' = √(73)

F' = 8.54 N.

(d)

F' = √[(F₁+F₂)²+(F₃+F₄)²]

Where F₁ = 20 N, F₂ = 10 N, F₃ = 20 N, F₄ = 20 N

F' = √[(20+10)²+(20+20)²]

F' = √[(30)²+(40)²]

F' = √[900+1600]

F' = √[2500]

F' = 50 N
