A constant force of 5.00 N acts on a 2.50 kg object for 10.0 s. The changes in the object’s momentum is 50 kg-m/sec and velocity 20 m/sec.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The acceleration of body,

a = 5/2.5

a = 2 m/sec²

change in velocity,

v - u = at = 2.10

change in velocity = 20 m/sec

change in momentum = 20. (2.50)

                                      =  50 kg-m/sec.

The change in the object's momentum is 50.0 kg·m/s, and the change in the object's velocity is 20.0 m/s.

To find the change in the object's momentum, we use the impulse-momentum theorem, which states that the impulse applied to an object is equal to the change in its momentum. Impulse is defined as the product of the force and the time interval over which the force is applied. Mathematically, this is expressed as:

[tex]\[ \text{Impulse} = \text{Force} \times \text{Time} \][/tex]

Given that the force (F) is 5.00 N and the time (t) is 10.0 s, we can calculate the impulse (I):

[tex]\[ I = F \times t = 5.00 \, \text{N} \times 10.0 \, \text{s} = 50.0 \, \text{N\·s} \][/tex]

Since 1 N = 1 kg·m/s², the impulse can also be written as:

[tex]\[ I = 50.0 \, \text{kg\·m/s}^2 \cdot \text{s} = 50.0 \, \text{kg\·m/s} \][/tex]

This impulse is the change in the object's momentum [tex][ \Delta p][/tex], so:

[tex]\[ \Delta p = I = 50.0 \, \text{kg\·m/s} \][/tex]

To find the change in the object's velocity [tex][ \Delta v][/tex], we use the definition of momentum (p), which is the product of mass (m) and velocity (v):

[tex]\[ p = m \times v \][/tex]

The change in momentum can also be expressed as:

[tex]\[ \Delta p = m \times \Delta v \][/tex]

We can solve for [tex][ \Delta v][/tex] by rearranging the equation:

[tex]\[ \Delta v = \frac{\Delta p}{m} \][/tex]

Given that the mass (m) of the object is 2.50 kg, we can calculate the change in velocity:

[tex]\[ \Delta v = \frac{50.0 \, \text{kg\·m/s}}{2.50 \, \text{kg}} = 20.0 \, \text{m/s} \][/tex]

Therefore, the change in the object's velocity is 20.0 m/s.

Answer: B

Longitudinal wave

Explanation:

Transverse waves have crests and troughs

Longitudinal waves have compressions and rarefactions. A compression is where the density of the wave medium is highest. While a rarefaction is where the density of the wave medium is lowest.

Since sound wave is a longitudinal wave. And longitudinal wave exists apart from sound, we can therefore conclude that it's a longitudinal wave in spring.

Explanation:

Did it on edgen just now

The acceleration of the airplane increasing its speed from 200 km/h to 300 km/h over 2 hours is 0.00386 m/s².

To calculate the acceleration of an airplane which increases its speed from 200 km/h to 300 km/h over a period of 2 hours, you need to use the formula for acceleration, which is the change in velocity Δv divided by the time interval Δt. In this case, the change in velocity is 300 km/h - 200 km/h = 100 km/h.

However, since acceleration is typically expressed in m/s², we should first convert the speeds from km/h to m/s. Doing so, we get approximately 55.56 m/s - 27.78 m/s = 27.78 m/s as the change in velocity.

Given the time interval is 2 hours, it should also be converted to seconds, resulting in 2 hours × 3600 seconds/hour = 7200 seconds.

The acceleration can now be calculated as:

Δv = 27.78 m/s
Δt = 7200 s
Acceleration (a) = Δv / Δt = 27.78 m/s / 7200 s = 0.00386 m/s²

Answer: atoms

Explanation:

Explanation:

: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.

Sounds at their source can be affected by various factors, including the Doppler effect and vibrations.

How this Numerous factors affect the properties of sound at its source

Vibrations:

The frequency of a sound dictates its pitch. The frequency and pitch of an object increase with its rate of vibration. Consider a guitar string that has been plucked quickly; this produces a higher frequency and higher-pitched sound.

Amplitude: This controls the sound's volume. The amplitude and loudness of the sound increase with the displacement of the vibrating object. Imagine pounding a drum more forcefully; the drum vibrates more, increasing the amplitude and producing a louder bang.

Form and composition of the oscillating object: The way that various materials and shapes vibrate affects the sound that is produced. For instance, the vibrations of a thin versus a thick drumhead will produce various sounds.

Force of excitation: Another important factor is how the object is made to vibrate. A soft pick versus a forceful strum is audible while picking a guitar string.

Doppler Effect:

This amazing phenomena varies the perceived pitch of a sound according on the listener's and the sound source's relative motion.

Moving source: Picture an ambulance driving toward you and sounding its siren. The siren seems to get louder as it approaches (you're really picking it on a higher frequency because the source is heading in your direction). On the other hand, it appears that the siren becomes quieter as the ambulance pulls away.

Listener in motion: A stationary sound source, such as a ringing bell, will sound louder in pitch if you run in that direction. The sound of the bell will become quieter as you run away from it.

These are but a few of the primary elements influencing sounds at the source. Recall that the intricate interaction of these elements creates the varied environment we encounter on a daily basis!

--> a = f/m

     a = 1000/1000                                                                                                                                        a= 1m/8*2                                                                                                                                           (b)   F = 1000N

      m = 2000 vg

       a = ?

--> F = ma

     a = f/m

     a = 1000/2000

     a = 0.5 m/8*2

a) The acceleration of the engine of the [tex]1000kg[/tex] mass of car is 1m/s².

b) The acceleration of the engine of the [tex]2000kg[/tex] mass of car is 0.5m/s².

Given the data in the question;

To determine the acceleration of each of the two cars,  we use Newton's Second Law of Motion:

[tex]F = m*a[/tex]

Where m is mass of the object and a is the acceleration.

For Car 1 { mass 1000kg}

[tex]1000N = 1000kg * a\\\\1000kgm/s^2 = 1000kg * a\\\\a = \frac{1000kgm/s^2}{1000kg}\\\\a = 1m/s^2[/tex]

Therefore, given the force exerted, the acceleration of the engine of a [tex]1000kg[/tex] mass of car is 1m/s².

For Car 2 { mass 2000 kg }

[tex]1000N = 2000kg * a\\\\1000kgm/s^2 = 2000kg * a\\\\a = \frac{1000kgm/s^2}{2000kg}\\\\a = 0.5m/s^2[/tex]

Answer:

The value of current generated would increase.

Explanation:

Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.

The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.

This experiment proves that an alternating current can be produced from magnetic field.

Final answer:

A more powerful battery in Faraday's experiments would have increased the induced electromotive force (EMF) causing the galvanometer to register a more significant deflection corresponding to the stronger magnetic field produced when the primary circuit was connected or disconnected.

Explanation:

Effect of a More Powerful Battery on Faraday's Experiment

British physicist Michael Faraday's experiments on electromagnetic induction were ground-breaking in showing the connection between electricity and magnetism. The use of a more powerful battery in Faraday's experiments would have affected the induced electromagnetic force (EMF) in the secondary coil. When Faraday connected his apparatus—comprising two coils, one known as the primary coil connected to a battery, the other referred to as the secondary coil connected to a galvanometer— he noticed an effect on the galvanometer only when the magnetic field was changing.

If a more powerful battery had been used, the current flowing through the primary coil would have been stronger. This would have created a more intense magnetic field. According to Faraday's law, the induced EMF in a circuit is proportional to the rate of change of magnetic flux. Therefore, with a stronger initial magnetic field, the rate of change of this field, and thus the induced EMF upon connecting and disconnecting the battery, would have been greater. The galvanometer would have registered a more significant deflection when Faraday either established or broke the circuit, corresponding to the moments of connection and disconnection of the battery.

Explanation:

formula is Wavelength x Frequency

Answer:

About 133 db.

Explanation:

Sound Intensity Level in db (SIL db) is equal to 10log (base 10) times the ratio of the sound intensity at 200 watts (I) relative to the sound intensity of  the reference sound intensity (I sub 0), which by default is equal to 10⁻¹² W/m² or 0 dB.

I = 200 w / 10 m^2 = 20 w per square meter  

I sub 0 = 10^-12 w per square meter

SIL = 10log ( I / I sub o) = 20 / 10^-12 = 10log ( 20^12) = 10 ( 13.3 ) = 133 db

Answer:160 g

Explanation:Start with the equation [tex]KE = 1/2mv^{2}.[/tex] This becomes [tex]m = 2KE/v^{2}[/tex]. Replace the variables with values and get (2*63)/28^2 = 160 g.

Final answer:

To find the mass of the puck, we use the kinetic energy formula: KE = ½mv². With the given kinetic energy of 63 Joules and velocity of 28 m/s, the calculation reveals that the mass of the puck is 0.1607 kg.

Explanation:

The student has asked a physics question relating to the concept of kinetic energy and its relation to mass and velocity. Kinetic energy (KE) is given by the equation KE = ½mv² where m represents mass and v represents velocity. Given kinetic energy is 63 Joules and velocity is 28 m/s, we will solve for mass (m).

Step 1: Write down the kinetic energy formula: KE = ½mv²

Step 2: Plug in the values: 63 J = ½m(28 m/s)²

Step 3: Simplify and solve for m:
63 J = ½m(784 m²/s²)
63 J = 392m (Joules)
m = 63 J / 392 (J/kg)
m = 0.1607 kg

The mass of the puck is 0.1607 kilograms.

The image of an object placed 2.0 meters in front of a plane mirror appears 2.0 meters behind the mirror, consistent with the Law of Reflection.

For plane mirrors, the Law of Reflection states that the angle of incidence is equal to the angle of reflection. This principle tells us that the image of an object will appear behind the mirror at the same distance as the object is in front of it. So if an object is placed 2.0 meters in front of a plane mirror, the reflected rays will appear to converge, and the image will seem to be 2.0 meters behind the mirror. Ray 1, traveling normal to the mirror, reflects back on itself, while Ray 2, traveling at a 5° angle, also reflects at a 5° angle on the other side of the normal. Thus, both rays will appear to originate from a point that is the same distance from the mirror as the object, creating a virtual image that is 2.0 meters behind the mirror.
