The coefficient of kinetic friction is 0.314.
Friction is the force resisting the relative motion of sturdy surfaces, fluid layers, and material factors sliding towards each specific. There are numerous styles of friction: Dry friction is a strain that opposes the relative lateral movement of two stable surfaces in touch.
Calculation:-
Force = 8000 N
mass = 2548 kg
a = f/mass
= 8000 / 2548
= 3.14 m/s²
Force = μkN
N = mg

if a moving clock appears to be ticking half as fast as normal, at what speed is the clock traveling? answer in units of m/s.
The speed with which the clock is traveling is 0.866*3*10^8 m/s.
We know that by Lorentz Time Dilation formula, T= T'/([tex]\sqrt{1-\frac{Velocity^{2}}{c^{2} } }[/tex]) -(i)
We also know that the clock is moving half times as faster.
Using equation number (i) and simplifying it further we get-
[tex]\sqrt{1-\frac{v^{2} }{c^{2} } }[/tex]= 1/2
1 - [tex]v^{2}[/tex]/[tex]c^{2}[/tex] = 0.25
[tex]v^{2}[/tex]/[tex]c^{2}[/tex] = 0.75
v/c = 0.866
v = 0.866 * c
Since we know that c is the speed of light in air and is equivalent to the value = 3*10^8, we get -
v = 0.866 * 3 * 10^8
Hence, the clock moves with a speed, v which is equivalent to 0.866 * 3 * 10^8 m/s.

what does the mass of a black hole need to be in order for its mass divided by its volume to be equal to the density of water (1g/cm3) ?
The mass of a black hole needs to be in order for its mass divided by its volume to be equal to the density of water (1g/cm³) is 7x10²¹ solar masses or 1.45 x 10⁵⁵g
A black hole is a collapsed star where all of the mass is concentrated into a single point in space. As it is a point, there is no volume. Therefore the density of the singularity is therefore infinite regardless of mass which is given by,
Density = Mass/Volume
Density =Mass/0
Density=Infinite
However, it is said that black holes have an event horizon, which is said to be the point where light is "captured" by the black hole. If we assume this event horizon is a spherical boundary for the black hole, then we can use its volume for our density calculation instead of the singularity.
Effectively, we could able to calculate the "average" density within the event horizon. The radius of the event horizon is called the Schwarzschild Radius, and can be found using the following formula,
R = 2MG/c²
where M is the mass of gravity, G is the gravitational coefficient and c is the speed of light. The volume of the spherical horizon could be computed as,
V = πR²
On substituting the value of R to this formula we get,
V = π(4M²G²)/c⁴
Density = c⁴/π(4MG²)
M = c⁴/4πPG²
If we consider the density to be the density of water that is 1g/cm², then mass could ve computed as,
[tex]M = \frac{(3*10^{8})^{4} }{3.14*4*1*(6.6743*10^{-11})^{2} } \\M = \frac{(3*10^{8})^{4}}{12.56*44.52*10^{-22}} \\M = \frac{81*10^{32}}{559.2833*10^{-22}}} \\[/tex]
M = 0.14482 x 10⁵⁴
M = 1.45 x 10⁵⁵ g

The velocity of sound waves is roughly the same for all wavelengths. Suppose that a sound wave has a wavelength of one meter and a frequency of 1000hz. The wavelength of a 250hz sound wave would then be.
Answer:
4 m
Explanation:
[tex]v = f \times λ[/tex]
speed of sound wave (according to question)
= 1 × 1000 = 1000m/s
wavelength is represented by λ
therefore to find the wavelength, divide the speed by the frequency of the second wave given by the question
λ of another wave = 1000 ÷ 250 = 4 m
Speed of sound equals wavelength and frequency. The wavelength of the sound wave if the frequency is 250hz is 4 meters.
What is the speed of sound waves?
Sound requires a medium to propagate in the form of vibration. It is the pattern of disturbance caused by the movement of energy particles propagating through the medium.
Sound waves can travel in the form of transverse and longitudinal waves. When the sound source continues to vibrate in the medium, the vibrations are propagated in the form of sound waves.
The sound waves travel at different speeds in different mediums. the speed of sound waves remains constant in the same medium. The speed of sound waves is directly proportional to wavelength and frequency.
Wavelength(λ) measures the distance between two crests/ two troughs in a wave and its SI unit is a meter. The frequency (f) of a wave is the number of waves that pass in a certain time and its unit is hertz(Hz). The SI unit of the speed sound wave is m/s.
From the givens,
wavelength(λ) = 1 meter.
frequency (f) = 1000hz.
Speed of wave(v) = wavelength × frequency
= 1 × 1000
v = 1000 m/s.
speed of wave = 1000 m/s.
frequency = 250hz
wavelength(λ) = speed / frequency
= 1000 / 250
= 4 meters.
Hence, the wavelength(λ) of a 250 hz sound wave is 4 meters.

There are two types of dipoles in electromagnetism.
The electric dipole deals with the separation of positive and negative charges found in electromagnetic systems. A simple example of this system is a pair of charges of equal magnitude and opposite sign, usually separated by a short distance. (A permanent electric dipole is called an electret.)
A magnetic dipole is a closed circuit in the current system. A simple example is a single wire loop with a constant current. An electric or magnetic dipole can be characterized by the vector quantity dipole moment. In a simple electric dipole, the electric dipole moment points from a negative charge to a positive charge and has a magnitude equal to the strength of each charge multiplied by the distance between the charges. (To be exact:
The "dipole limit" should always be considered when defining the dipole moment. For example, the generated charge spacing should converge toward 0, but at the same time the charge strength should diverge toward infinity so that the product does not change. positive constant)

OC. the possible next moves of the suspect
O D.
the history or childhood trauma of the suspect
Answer: A. The name of the suspect
Explanation: Hope this helps!:)
The name of the suspect could not be provided by a criminal profiler. So, the correct option is A.
What is Criminal profiler?Criminal profiling is also referred to as offender profiling, is a method of investigation used by law enforcement to find potential suspects and by investigators to connect crimes that might have been committed by the same person.
Criminal profilers are highly skilled professionals that focus on locating the individuals responsible for heinous crimes. Along with forensics teams and other law enforcement personnel, profilers work to identify suspects using methods including in-depth psychological understanding and statistical probability.
The FBI defines the criminal profiling procedure as a method for locating the perpetrator of a violent crime by determining the personality and behavioural traits of the offender based on an examination of the crime that was committed.
Thus, the correct option is A.

According to newton’s first law of motion, an object in motion will stay in at the same speed and direction unless acted upon by what kind of force?.
The vertical impulse by the lift force during this time is 4.15 by minutes for newton's law of motion.
Explanation-
We have a demon That there is a force of 52 down cause of 15. Right? This is what we have you in the questions and acting on the bill. Be both masked by Graham of Mars five g. No. In the meantime. And travelers given that the time and develop acting on this fourth, you should humanists. But we need to find the impulse England's. They seem to not advise you actually. This is what we need to find. So we know that false change in momentum much time. So basically impulses change momentum, but you find impulses changing moment also jay so G is false in campaign so we can put forth here. The forces to do time 59 1 dime. That's Spanish for -5.

an object at rest on a flat, horizontal surface explodes into two fragments, one seven times as massive as the other. the heavier fragment slides 5.90 mm before stopping. how far does the lighter fragment slide?
The lighter fragment slide to a distance of 289.1m.
The distance between two points is referred to as its length.
7m in mass for the heavier fragment
The lighter fragment's velocity is equal to V1.
The velocity of larger pieces is equal to V2.
mv1 + 7mv2 = 0
V1 = -7V2
The frictional force on lighter fragment: f1 = mg
Friction force on a heavier piece is equal to f2 = 7 mg.
The lighter fragment's deceleration equals a1.
frictional force = ma1 = - f1
ma1 = - µmg
a1 = - µg
Deceleration of the heavier piece equals a2.
7ma2 = -f2
7ma2 = - 7µmg
a2 = - µg
V₃²= V₁² + 2a₁d₁
0 = (-7v₂)² + 2(-µg) d₁
d₁ = 49v₂²/ 2µg
d₁ = 49d₂ = 49 ˣ 5.9 = 289.1m
