1. What is the total distance traveled?
A 3.0m
B 4.0m
C 5.0m
D 6.0m

Answer:

Distance Is how far an object has moved.

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m).

Work = Force × Distance.

W = 10 N × 0.75 m

Injury is any physical damage or harm caused to the body, including cuts, scrapes, bruises, broken bones, and burns. It can be caused by an accident, medical negligence, or intentional harm. Injuries can range from mild to severe and can be temporary or permanent. Treatment for an injury often involves rest, medications, physical therapy, and sometimes surgery. In more severe cases, an injury can cause lasting disability or even death. Prevention of injuries is important, and can be achieved through education, wearing protective gear, and avoiding risky activities.

Answer:

The pitch that he hears after the truck passes and is moving away is 819.6 Hz.

Explanation:

The pitch that he hears after the truck passes and is moving away can be calculated using the following equation:    

[tex] f = f_{0}*\frac{v_{s} \pm v_{o}}{v_{s} \pm v_{f}} [/tex]

Where:

[tex]f[/tex]: is the perceived frequency

[tex]f_{0}[/tex]: is the emitted frequency

[tex]v_{s}[/tex]: is the speed of sound = 340 m/s

[tex]v_{o}[/tex]: is the speed of the observer = 0 (he is not moving)

[tex]v_{f}[/tex]: is the speed of the fire truck

First, we need to find the speed of the fire truck. When it approaches the observer we have:

[tex] f = f_{0}*\frac{v_{s} + v_{o}}{v_{s} - v_{f}} [/tex]

[tex] 950 Hz = 880 Hz*\frac{340 m/s}{340 m/s - v_{f}} [/tex]

[tex] v_{f} = 340 m/s - \frac{880 Hz*340 m/s}{950 Hz} [/tex]

[tex] v_{f} = 25.05 m/s [/tex]

Hence, the speed of the fire truck is 25.05 m/s.

Now, we can calculate the pitch that the observer hears after the truck passes:

[tex] f = f_{0}*\frac{v_{s} - v_{o}}{v_{s} + v_{f}} [/tex]

[tex] f = 880 Hz*\frac{340 m/s}{340 m/s + 25.05 m/s} [/tex]

[tex] f = 819.6 Hz [/tex]

Therefore, the pitch that he hears after the truck passes and is moving away is 819.6 Hz.

Answer:

velocity and wavelength likely to change in the process.

Explanation:

When an object passes from one medium to another, refraction occurs. Due to refraction, it changes iits direction. Some of the properties is changed when it undergoes refraction. The velocity of a wave and wavelength change in this process.

Hence, the correct option is (a) "velocity and wavelength".

Answer:

Explanation:

Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles. Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.

Increasing the pressure of a gas is exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume. If you have the same mass in a smaller volume, then its concentration is higher.

Answer:

this point we have a destructive inference  m=1

Explanation:

This is an interference exercise, where the light has two possible states one of constrictive interference

            d sin θ = m λ

and another of destructive interference

           d sin θ = (m + ½) λ

the term on the left is the difference in trajectory that tells us that it is worth

            d sin θ = 300 nm = 300 10⁻⁹ m

We can find what type of interference we have by finding m, which must be an integer

constructive interference

           m = d sin θ /λ

let's calculate

          m = 300 10⁻⁹ / 500 10⁻⁹

          m = 0.6

this value is not possible because m must be an integer

destructive interference

          m + ½ = d sin θ /λ  

          m = d sin θ /λ  + ½

          m = 0.6 + 0.5

         m = 1.1

that can be approximated to m = 1

this value if possible, so at this point we have a destructive inference

Answer:

[tex]\boxed {\boxed {\sf 14 \ meters \ per \ second}}[/tex]

Explanation:

Speed is the rate of motion and can be found by dividing the distance by the time.

[tex]s=\frac{d}{t}[/tex]

The distance covered is 56 meters and the time taken is 4 seconds.

[tex]d= 56 \ m \\t= 4 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac{56 \ m}{4 \ s}[/tex]

Divide.

[tex]s= 14 \ m/s[/tex]

The speed of the car is 14 meters per second

Answer:

it is a ionic bond because electrons are transferred from chlorine to strontium

Strontium chloride, SrCl₂, is an ionic compound because Ionic compounds are formed through the transfer of electrons from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions).

In the case of strontium chloride, strontium (Sr) is a metal, and chlorine (Cl) is a non-metal. Strontium readily donates two valence electrons to chlorine, which has a strong affinity for gaining one electron to achieve a stable electron configuration. The electron transfer between strontium and chlorine leads to the formation of S[tex]r^2^+[/tex] cations and C[tex]l^-[/tex] anions. The resulting ionic bond holds the cations and anions together in a crystal lattice structure. The attraction between the oppositely charged ions creates the ionic bond, making strontium chloride an ionic compound.

Explanation:

Answer: the acceleration is 1.282 m/s²

Explanation:

Given that;

Time t = 13 sec

Initial velocity U = 5 kmph = (5 × 1000)/(60 × 60) = 1.3888 m/s

final velocity V = 65 kmph = (65 × 1000)/(60 × 60) = 18.0555 m/s

Now we know that;

V = U + at

we substitute

18.0555 = 1.3888 + 13a

18.0555 - 1.3888 = 13a

13a = 16.6667

a = 16.6667 / 13

a = 1.282 m/s²

Therefore the acceleration is 1.282 m/s²

Answer:

The cork moves up and down.

Explanation:

The cork moves up and down because of the waves produce due to tapping the surface of water. The cork experience movement due to placed on the water surface so when the wave passes through the medium by tapping of water, movement of cork also occur. Cork has high volume and lower mass so it floats on the water surface and experience movement due to waves.

Answer:

The value is [tex]s =197.88 \ m[/tex]  

Explanation:

From the question we are told that

    The  impulse is  [tex]I = 950 \ N\cdot s[/tex]

    The mass is  [tex]m = 12 \ kg[/tex]

     The time t =  5 s

Generally impulse is mathematically represented as

         [tex]I = F * t[/tex]

=>       [tex]F = \frac{I}{t}[/tex]

=>       [tex]F = \frac{950 }{ 5 }[/tex]

=>       [tex]F = 190 \ N[/tex]

Generally force is mathematically represented as

      [tex]F = m * a[/tex]

=>    [tex]a = \frac{F }{ m }[/tex]

=>     [tex]a = \frac{190 }{ 12 }[/tex]

=>     [tex]a = 15.83 \ m/s^2[/tex]

Generally from kinematic equation , the distance covered is  

      [tex]s = ut + \frac{1}{2} * at^2[/tex]

Here  u is the initial velocity of the cart and the value is [tex]u = m/s[/tex]

=>   [tex]s = 0 * 5 + \frac{1}{2} * 15.83 * 5^2[/tex]  

=>   [tex]s =197.88 \ m[/tex]
