a sound wave has a frequency of 1192 hertz. all sound waves in air travel at 322m/s. find the wave length of the sound wave

Answer:

They are directly proportional to gravitational force.

Explanation:

Newton's Law of Gravity states that [tex]F_G=\frac{Gm_1m_2}{r^{2}}[/tex]. The two "m" values are the masses of the objects, r is the distance between their centers, and G is the gravitational constant. Notice how the "m" values are in the fraction's numerator (i.e., on top)? That means increasing even one of the objects' masses will increase the gravitational force. This is known as a direct relationship.

Of course, you could always use the wonderful table provided to solve this! You don't believe what I wrote above? Take on of the two objects' masses, divide the gravitational force by that number, and see what happens. Multiply the two masses together, and see what happens. Prove it for yourself!

I hope this increases your understanding of this concept. Have yourself a wondrous day, 'kay?

Answer:

2. increase

3. stay the same

4. Decrease

Explanation:

(let me know if im wrong on any we learned this last year so I might be a little rusty on this subject)

The force of gravity increases with increase in the size of the Sun and with decrease in the distance between the earth and the Sun. However, it decreases with decrease in the size of the earth.

Gravity is the force of attraction that exists between two bodies separated by a given distance.

The force of gravity increases with increase in the size of the bodies as well as with a decrease in the distance of separation.

However, the force of gravity decreases with decrease in the size of the bodies as well as with a increase in the distance of separation.

Thus, for the force of gravity between the earth and the Sun;

Therefore, the force of gravity is affected by size of the bodies as well as the distance separating the bodies.

B seismic wave

Answer: s=d/t= 500/7.0=71.42 m/s

Explanation:

If a runner goes 500 meters with an average speed of 7.0 m/s, then he would have run in about 71.42 seconds.

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

average speed = total distance /Total time

As given in the problem If a runner goes 500 meters with an average speed of 7.0 m/s then we have to find out How long was he running,

time consumed  by the runner = distance covered by the runner/average speed of the runner

time consumed  by the runner = 500 meters /7 meters/seconds

                                                   = 71.42 seconds.

Thus, the time consumed by the runner would have been 71.42 seconds.

b...radio waves answer

Answer:

Gravity.

Explanation:

The force that controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped in clusters is called gravity.

This ultimately implies that, gravity is considered to be a universal force of attraction that acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, weight is given by the formula;

[tex] Weight = mg [/tex]

Where;

m is the mass of an object.

g is acceleration due to gravity.

Answer:

the speed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance ÷ time

So, here speed be 515 m

And, the time is 1.50 seconds

So, the speed of the sound is

= 515 m ÷ 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s

Explanation:

Answer:

Explained below

Explanation:

Newton's first law of motion: This law states that an object will remain at rest or continue in constant motion except it's acted upon by an external force. In projectile motion, the horizontal component of velocity will remain unchanged because we ignore air resistance since no force is acting in that horizontal direction.

Newton's second law of motion: This law states that force is the product of mass and acceleration. In projectile the force acts downwards, thus f = mg.

But g = a since internal forces will cancel out.

Thus, F = ma

Famous French mathematician, physicist, and philosopher Blaise Pascal announced this law in the year 1647.

According to this law, pressure applied to a liquid that is at rest is uniformly distributed throughout.

There are numerous uses for it in daily life. Numerous gadgets, like hydraulic lifts and brakes, are based on Pascal's law.

For incompressible fluids, Pascal's concept is applicable. The majority of vehicle repair shops using lifts use one common use. In essence, air from an air compressor is delivered to the top of oil in a container; the oil then exerts pressure on a sleeve or piston that raises the car.

Force =  mass x acceleration

if the force is constant for each of the boxes, the smaller a boxes mass the greater its acceleration while the force is applied

Therefore the smaller box will have a greater initial velocity and will slide the furthest before it stops.

Answer:

It takes the Sun's light 7.17 minutes to reach us.

Explanation:

We can calculate the time that takes the light to reach us by using the following equation:

[tex] t = \frac{d}{c} [/tex]    

Where:

d: is the distance = 1.29025x10⁸ km = 1.29025x10¹¹ m

c: si the speed of light = 2.99792x10⁸ m/s  

Hence, the time is:

[tex] t = \frac{d}{c} = \frac{1.29025 \cdot 10^{11} m}{2.99792 \cdot 10^{8} m/s} = 430.38 s = 7.17 min [/tex]

Answer:

[tex]P(X\ge 1) = 0.9502[/tex]

Explanation:

Given

Density = 3 starts in 10 cubic light years.

Required

Determine the probability of 1 or more in 10 cubic light years

Since the number of stars follow a Poisson distribution, we make use of:

[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]

[tex]\lambda = density[/tex]

[tex]\lambda = \frac{3}{10}[/tex]

[tex]\lambda = 0.3[/tex]

T = the light years

[tex]T = 10[/tex]

Calculating [tex]P(X \ge 1)[/tex]

In probability:

[tex]P(X \ge 1) = 1 - P(X = 0)[/tex]

Calculating P(X=0)

Substitute 0 for k and the values for [tex]\lambda[/tex] and T in

[tex]P(X=k) = f(x) = (\lambda T)^k\frac{ e^{-\lambda T}}{k!}[/tex]

[tex]P(X=0) = (0.3* 10)^0 * \frac{ e^{-0.3 * 10}}{0!}[/tex]

[tex]P(X=0) = (3)^0 * \frac{ e^{-0.3 * 10}}{1}[/tex]

[tex]P(X=0) = (3)^0 * e^{-0.3 * 10}[/tex]

[tex]P(X=0) = 1 * e^{-0.3 * 10}[/tex]

[tex]P(X=0) = 1 * e^{-3}[/tex]

[tex]P(X=0) = e^{-3}[/tex]

[tex]P(X=0) = 0.04979[/tex]

Substitute 0.04979 for P(X=0) in [tex]P(X \ge 1) = 1 - P(X = 0)[/tex]

[tex]P(X\ge 1) = 1 - 0.04979[/tex]

[tex]P(X\ge 1) = 0.95021[/tex]

[tex]P(X\ge 1) = 0.9502[/tex] ---  approximated

Hence, the required probability is 0.9502

6 Newtons to the left.

Explanation:

We can convert  this into a generic algebra equation by giving directions positive and negative values.

The 6 will be positive, and the 10 and 2 will be negative.

Add 10 and 2 to have 12.

6-12 = -6.

Therefore you have 6 newtons to the left (negative).

Answer:

Suppose that the frequency of the first harmonic is F, then the frequency of the second harmonic will be 2*F

The third one will be 3*F

and so on.

Then:

a) the first harmonic is 262 Hz,

Then the third harmonic will be 3*262Hz = 786 Hz

b) if F is the frequency of the first harmonic, and we want to find this.

We know that the fifth harmonic frequency is 1700Hz

Then:

5*F = 1700 Hz

F = (1700Hz)/5 = 340Hz

c) We want to find the fifth harmonic such that we know that the third overtone frequency is 984 Hz.

An overtone is any frequency larger than the fundamental frequency; overtone is just another name for harmonic.

Such that the second overtone is the same as the second harmonic, the third overtone is the same as the third harmonic, etc.

Then the third overtone is the same as the third harmonic.

This means that if F is the first harmonic, then:

3*F = 984 Hz

F = 984Hz/3 = 328 Hz

And the fifth harmonic will be:

5*328 Hz = 1640 Hz

Answer:

Approximately 92 mm.

Explanation:

Object's distance, u = 110 mm = 11 cm

focal length of the mirror = 5 cm

Image distance, v = ?

To determine the image distance, apply the mirror's formula;

[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{u}[/tex] + [tex]\frac{1}{v}[/tex]

[tex]\frac{1}{v}[/tex] = [tex]\frac{1}{f}[/tex] - [tex]\frac{1}{u}[/tex]

   = [tex]\frac{1}{5}[/tex] - [tex]\frac{1}{11}[/tex]

   = [tex]\frac{11-5}{55}[/tex]

[tex]\frac{1}{v}[/tex] = [tex]\frac{6}{55}[/tex]

⇒ v = [tex]\frac{55}{6}[/tex]

       = 9.166667

v = 9.2 cm

The image distance is 92 mm.
