Answer:

A wave is a disturbance of the space (or of a medium), that carries energy without transmitting matter.

A wave is produced when there is a periodic vibration in the particles of a medium (mechanical wave), or when there is a periodic oscillation of the electric and magnetic fields (electromagnetic waves). Electromagnetic waves are the only ones that can travel through a vacuum.

Mechanical waves are further classified into two types, depending on how the particles in the medium vibrate:

- If they vibrate up and down (perpendicular to the direction of motion of the wave), they are called transverse waves

- If they vibrate back and forth (parallel to the direction of motion of the wave), they are called longitudinal waves

In general, waves are generated from a precise point in the space, which is called source of the wave. The source of the wave does work, since it is responsible for starting the motion of the particle, and make them starting vibrating, so it transmits energy to the particles.

what will the stopping distance be a a 3000-kg car if -3000N of force are applied when the car is traveling 10 m/s
Inga [223]

Answer:

50 m

Explanation:

Acceleration= force/mass

3000/3000=1m/s^-2

Applying equation of motion:

V^2=U^2+2as; V is final velocity, u is initial velocity, a is acceleration and s is the distance covered.

0=10^2 -2*1s;

Solve for s

Explain how thermal energy (temperature) affects chemical changes.
Monica [59]
If bonds are broken, the energy is released, and if bonds are formed, energy is absorbed. During conversions from chemical energy to thermal energy, the energy stored in the chemical bonds are released and this energy causes surrounding molecules to move faster thus increasing the thermal energy of a substance.

A physics professor demonstrates the Doppler effect by tying a 600 Hz sound generator to a 1.0-m-long rope and whirling it aroun
nalin [4]

Answer:

Therefore the the highest frequency is 620Hz and lowest frequency is 580Hz

Explanation:

Given data

Source Frequency fs=600Hz

Length r=1.0m

RPM=100 rpm

The speed of the generator is calculated as:

v_{s}=rw\\v_{s}=r(2\pi f)

Substitute the given values

v_{s}=(1.0m)2\pi (\frac{100}{60}rev/s )\\v_{s}=10.47m/s

For approaching generator the frequency is calculated as:

f_{+}=\frac{f_{s}}{1-\frac{v_{s}}{v} }\\f_{+}=\frac{600Hz}{1-\frac{10.47m/s}{343m/s} } \\f_{+}=620Hz

On the other hand,for the receding generator,Doppler's effect is expressed as:

 f_{-}=\frac{f_{s}}{1+\frac{v_{s}}{v} }\\f_{-}=\frac{600Hz}{1+\frac{10.47m/s}{343m/s} } \\f_{-}=580Hz

Therefore the the highest frequency is 620Hz and lowest frequency is 580Hz
