The loudness of a sound is related to the ___________ of the vibration that produces the sound.

A sailboat moves north for a distance of 10.00 km when blown by a wind from the exact south with a force of 5.00 x 10^4 n. how m

Nataliya [291]

Work is defined as the force times the distance which is mathematically expressed W = Fxd. The given force is 5x10^4 and the distance is 10000 m (the distance is converted as meter because Nm = J) the work done by the wind is W = 5x10^4 N (10000) = 500 x 10^6 Joules. I hope it answered your question

9. Seismic waves are

Brilliant_brown [7]

d. both a and b

Explanation:

Seismic waves are both transverse and compressional or longitudinal waves.

A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.

Seismic waves are both longitudinal and transverse waves.
There are two main types of seismic waves which are the surface and body waves.
The surface waves runs on the earth surface. These are the rayleigh and love waves.
The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
Body waves moves within the earth surface. They are p-waves and s-waves.
P-waves are longitudinal or compressional waves that propagates within the earth surface.
S-waves are transverse waves that moves perpendicularly to their direction of propagation.

Hurry!!!!!!!!!!!!!!! Match the terms to the correct descriptions.

Rashid [163]

This can be either kinetic or potential and has to do with the energy of position and motion of an energy- This is related to mechanical energy.It is so because mechanical energy is the sum total of kinetic and potential energy.

This is radiant energy from the sun;it is the only kind of energy we can see with our eyes-It is related to light energy which consists of white light along with its seven colors and these are also electromagnetic radiations.

This is the energy that is transferred by the movement of electrons through a conductor;the electrons create a current-This is related to electric energy.

This type of energy is often found in things like batteries or food-This is related to chemical energy .It is chemical energy which is converted to electrical energy in battery.

This type of energy travels through vibrations on waves-This is related to sound energy which travels in a medium in the form of compressions and rarefactions.

This type of energy is found in the nucleus of an atom-This is related to nuclear energy.For instance the energy produced during nuclear fusion and fission from unstable nuclei.

This is the term used when one type of energy changes from one form to another-This is related to energy conversions.

This type of energy is stored energy;it can be increased by getting into a higher position and/or stretching an object such as a rubber band-This is related to potential energy .It is the energy gained by a body due to its position or change in configurations.

This type of energy can be transferred in three different ways i.e conduction,convection and radiation-We know that heat is transferred in three different ways mentioned above and heat is nothing else than transferred thermal energy.Hence, it is related to thermal energy.

This has to do with the speed of an object and how much mass it has;basically how the how the object is moving-This is related to kinetic energy which is the energy gained by a body due to its motion.

Mathematically it is written as

$kinetic\ energy =\frac{1}{2} mass*[velocity]^2$
