The minimum coefficient of friction required is 0.885 for a 925kg car rounds an unbanked curve at a speed of 25m/sec.
We know that if a body wants to travel from one place to another place, we need friction to move along the surface.
Now,we know that centripetal force is required to move along a curve.Also,due to friction same amount of force acts on the car to move along the surface.
It means centripetal force=mv²/r where v is the velocity of the body and r is the radius of the body is equal to force applied by the friction which is equal to =μmg
So,mv²/r=μmg
=>v²/r =μg
=>μ= v²/rg
On putting the values of speed, radius and acceleration due to gravity
=>μ=(25)²/(72×9.8)
=>μ=625/705.6
=>μ=0.885
Hence, required value of coefficient of friction is 0.885.

A massive tractor is rolling down a country road. In a perfectly inelastic collision, a small sports car runs into the tractor from behind. Which vehicle experiences a larger change in kinetic energy?.
Small sports car will experience a larger change in kinetic energy during inelastic collision.
In inelastic collision we know that loss of energy is possible. It means law of conservation of energy is not possible. An inelastic collision is an impact where there is a deficiency of motor energy. While force of the framework is moderated in an inelastic collision, motor energy isn't. This is on the grounds that some dynamic energy had been moved to something different. Nuclear power, sound energy, and material distortion are reasonable offenders.
Car has small mass as compared to a massive tractor. Due to its high mass car have greater speed as compared to massive tractor. During inelastic collision when a small mass car is collided with large massive tractor ,it transfers most of its energy to a massive tractor and lost that energy in form of heat.

a uniform beam is suspended horizontally by two identical vertical springs that are attached between the ceiling and each end of the beam. the beam has mass 225 kg, and a 175-kg sack of gravel sits on the middle of it. the beam is oscillating in shm, with an amplitude of 40.0 cm and a frequency of 0.60 cycles/s.What is the frequency of the subsequent SHM of the beam?
1. What is the amplitude of the subsequent SHM of the beam?
2. If the gravel instead falls off when the beam has its maximum speed, what is the frequency of the subsequent SHM of the beam?
3. What is the amplitude of the subsequent SHM of the beam?
The frequency and amplitude of the SHM beam is 0.8 Hz and 0.098 m. The frequency of the SHM wave when gravel falls is 0.8 Hz and the amplitude of subsequent SHM beam is 0.4m.
(a) Mass of the spring = 225 Kg
Mass of the sack = 175 Kg
Amplitude of the beam = 40 cm = 0.40 m
Frequency of the beam = F = 0.60 cycles/s
The formula for frequency of oscillation =
= f = (1/2π) X √(k/m)
where, k = 2π²F²m
= k = 2 X (3.14)² X 0.6² X (225 + 175)
= k = 5685.37 N/m
Strength of the spring before gravels fall = x =
= x = mg / k
= x = [ (225 + 175 ) X 9.8 ] / 5685.37
= x = 0.689 m
But, the spring is stretched by the distance of x' which is expressed as,
= X = x - x'
= X = 0.689 - 0.40
= X = 0.289 m
Now, since we know that the gravel falls, thus frequency = f =
= f = (1/2π) X √(k/m)
= f= (1/ 2 X 3.14) X √ 5685.37 / 225
= f = 0.8 Hz
(b) Assuming that the spring is stretched, x = mg/k =
= x = (225 X 9.8) / 5685.37
= x = 0.3878 m
Thus, the amplitude of the sack = A = 0.3878 - 0.289
= A = 0.098 m
(c) If the gravel falls, the speed is maximum hence speed = s =
= s = A X √(k/m)
= s = 0.4 X √(5685.37/400)
= s = 1.508 m/s
The frequency = f' =
= f' = (1/2π) X √(k/m)
= f' = (1/2 X 2.14) X √(5685.37/225)
= f' = 0.8 Hz
(d) New amplitude = A' =

how are rotation curves of spiral galaxies determined beyond radii where starlight can be detected?
Rotation curves of spiral galaxies are a measure of the velocity of the stars and gas in the galaxy as a function of distance from the center. These curves are important for understanding the mass distribution of the galaxy, which in turn helps us understand the structure of the galaxy and its evolution.
In order to determine the rotation curves beyond the radii where starlight can be detected, we must use indirect methods. One of the most important indirect methods is the use of neutral hydrogen gas, which is typically found in the outer regions of galaxies. By measuring the Doppler shifts of the hydrogen gas using radio telescopes, we can determine the velocity of the gas as a function of distance. This allows us to trace the rotation curve out to much larger radii than just the starlight.
Another method for determining the rotation curves beyond the radii where starlight can be detected is to use gravitational lensing. This method relies on the fact that the gravity of a massive object, such as a spiral galaxy, can bend and focus the light from more distant objects. By measuring the distortions of the light from those distant objects, we can infer the mass distribution of the galaxy and thus its rotation curve.

A truck is traveling at speed of 15 m/s on a slippery road. It will travel a distance of 57.4 meters before finally stop.
Using the Newton's 2nd law of motion:
Fs = m . a
Where:
Fs = friction force
m = mass of the truck
a = acceleration
Fs = μ . N
= μ . mg
Where:
μ = coefficient of kinetic friction the tires and the road = 0.2
N = normal force = m . g
Hence,
μ . mg = m . a
a = μ . g
= 0.2 x 9.8 = 1.96 m/s²
Using the equation of motion for a decelerated motion:
v² = u² - 2as
Where:
v = final speed = 0 (since the truck finally stop)
u = initial speed
s = distance
Hence,
0 = 15² - 2 x 1.96 x s
s = 225 / 3.92 = 57.4

What is a type of kinetic energy?
Kinetic energy is a type of mechanical energy.
Kinetic energy is defined as the energy produced by a body in motion. When an object is accelerated it is imperative that a certain force is applied. Applying a force requires work, and after the work is done, the energy is transferred to the object, causing it to move at a constant speed.
The energy transferred is called kinetic energy and depends on the velocity and mass of the body in motion.
Considering the kinetic energy equation above, let us consider some practical examples.
Airplanes have a lot of kinetic energy in flight because of their high speed and mass.Despite its small size and mass, a baseball has a large amount of kinetic energy after being thrown at high speed.Skiers coming down from above exhibit enormous kinetic energy due to their high speed and mass.Before hitting a golf ball, it has zero velocity and therefore no kinetic energy.When an asteroid falls at incredible speed, it has a huge amount of kinetic energy.Cars have less mass than trucks, so they have less kinetic energy on the road than trailer trucks.To understand more about mechanical energy -

how do population of juvenile salmon alter respond to changes in salinity
Poorly Understood
The influence of salinity, temperature and physiological development on habitat choice by juvenile salmon is poorly understood.
Answer:
Below
Explanation:
It is likely that changes in salinity can affect the population of juvenile salmon in a number of ways. For example, if the salinity of the water increases, it can lead to increased stress on the fish and make it more difficult for them to survive.
This can lead to a decrease in the population of juvenile salmon. On the other hand, if the salinity decreases, it can make it easier for the fish to survive and potentially lead to an increase in the population.
It is important to note, however, that the exact response of the population to changes in salinity will depend on a variety of factors, such as the species of salmon, the specific environment in which they are living, and the magnitude of the change in salinity.

in a lab experiment, a sensor is placed to detect the motion of an object relative to the sensor. the sensor was set up to identify the direction away from it as positive. a set of data including the velocity, and acceleration of the object at every 0.01s was recorded. if the values of both, velocity and acceleration, are negative, what statement below about the motion of the object is correct?
The statement below concerning the item's motion is true since the object was edging farther away from the sensor while slowing down.
What are the three categories of acceleration?The three main categories of accelerated movements are uniform, non-uniform, and average acceleration. When an item moves in a straight path with an increase in speed occurring at regular intervals of time, this motion is referred to as having uniform acceleration.
How do acceleration and velocity compare?Velocity is the rate at which displacement changes. The pace at which speed changes is known as acceleration. Because it consists of both magnitude and direction, velocity is a vector quantity. Since acceleration is only the rate at which velocity changes, it too is a vector quantity.

b) index of refraction
Three light-related phenomena are the subject of extensive research.
1) Rainfall's ability to disperse sunlight in the atmosphere.
2) The changing degrees of refraction of white light, which results in the construction of a rainbow arch.
3) The complete interior reflection of the raindrop. Refraction happens when light enters one medium and then exits another, producing our reaction.
Refraction, which is indicated by the light's bending or change in direction, can occur when electromagnetic energy in the form of visible light passes from one substance or medium to another.
Total internal reflection happens when light rays enter a right-angled glass prism at an angle of incidence larger than the critical angle.
