Answer:

option 1

Explanation:

A chemical reaction occurs when two or more molecular structure rearrange causing a change in the chemical transformation of one of the substance. During a chemical reaction, old bonds break and new bonds are formed. The energy is conserved during a chemical reaction. The energy released during breaking of the old bonds are used to form new ones.

Thus. option 1 is correct.

<span>The statement that is true of the energies required to break bonds is this: 

the energy needed to break the required bonds is greater than the energy released when the new bonds form.

Bonds that have been formed during specific reactions require much energy to be broken down again because of the closed atomic bond that have formed during the process.</span>

Maria drove to the store and then to work . What is marias total displacement during her trip
antoniya [11.8K]

Explanation:

Displacement is the shortest distance between two points. Displacement is used to calculate vector quantities such a velocity, force, acceleration, etc.

Here, Maria drove to the store and then to work this means that her total displacement will be the minimum distance between her initial point and her work place.

Hence, the minimum distance between her initial point and her work place is her total displacement.

A helicopter goes straight up 500m from a landing pad. It then goes north 20m. Then it goes down 452m. a) What is the displaceme
gavmur [86]

Answer:

a

  x-component             20 \  m

y-component     500 -  452 =  48 \  m

b

 Magnitude d  =  52 \  m

direction is  \theta  = 67.4^o

Explanation:

From the question we are told that

   The first  vertical distance is  y_1   = 500 \  m

    The  first horizontal distance  is  x =  20 \  m

    The  second vertical distance is  y_2  =  452 \  m

Generally the displacement is  

x-component             20 \  m

y-component     500 -  452 =  48 \  m

Generally the helicopters displacement is mathematically evaluated as  

       d  =  \sqrt{ x- component ^2  +  y- component ^2 }

      d  =  \sqrt{ 20t ^2  + 48 ^2 }

      d  =  52 \  m

The  direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as

         \theta  = tan ^{-1}[ \frac{48}{20}]

=>       \theta  = tan ^{-1}[ 2.4 ]

=>      \theta  = 67.4^o

A sound wave, generated at a frequency of 440 hertz has a wavelength of 2.3 meters as it travels through a solid material. The a
Jlenok [28]

The approximate speed of the sound wave traveling through the solid material is 1012m/s.

<h3>Wavelength, Frequency and Speed</h3>

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

  • Frequency of sound wave f = 440Hz = 440s⁻¹
  • Wavelength of the wave λ = 2.3m
  • Speed of the wave v = ?

To determine the approximate speed of the wave, we substitute our given values into the expression above.

λ = v ÷ f

2.3m = v ÷ 440s⁻¹

v = 2.3m × 440s⁻¹

v = 1012ms⁻¹

v = 1012m/s

Therefore, the approximate speed of the sound wave traveling through the solid material is 1012m/s.
