The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.

The difference between the momentum before and after the bounce was 1.407 kg/s.

initial energy = mg(3) J = 29.4J

After bouncing ,energy = mg(2) =19.6J

Ball's change in energy = 29.4J - 19.6J = 9.8J

This energy is dissipated in the form of heat energy or sound energy.

work done during the bounce = 9.8J

change in momentum = mvf-mvi

29.4 = 1/2m\(vi^{2}\)

vf =7.668m/s

19.6J =1/2m\(vf^{2}\)

vf=6.261m/s

The amount of the 1 OS of this sample is 378.96 mg/L.

When calculating the concentration of the sample, one should first determine the mass of the sample residue in grams.

To do so, subtract the mass of the empty evaporating dish from the mass of the evaporating dish and dried residue. Then, calculate the volume of the sample in liters, using the conversion factor of 1 mL = 1 × 10⁻³ L.

Substitute the values obtained into the following formula:1 OS = (m/V) × 10⁶

where m is the mass of the sample residue in grams, V is the volume of the sample in liters and the result is multiplied by 10⁶ to convert from g/L to mg/L.

According to the given information,

Mass of the empty evaporating dish, m1 = 37.320 g

Mass of the evaporating dish and dried residue, m2 = 38.110 g

Volume of the sample = 50 mL = 50 × 10⁻³ L = 5 × 10⁻² L

Therefore, the mass of the sample residue is:

m2 - m1 = 38.110 g - 37.320 g = 0.790 g = 7.90 × 10⁻⁴ L

Consequently, the 1 OS of the sample is:

1 OS = (m/V) × 10⁶= (7.90 × 10⁻⁴ g/5 × 10⁻² L) × 10⁶= (7.90 × 10⁴ g/L) = 378.96 mg/L (rounded to two decimal places)

The charge per unit length (λ) on the capacitor when it is charged to 145 V is approximately \(8.70 × 10^-9 C/m.\)

To find the charge per unit length (λ) on the capacitor, we need to use the equation:

Q = CV

Where Q is the charge stored in the capacitor, C is the capacitance, and V is the potential difference across the capacitor.

From the passage, we know that the capacitance of the capacitor is 9.00 pF and the potential difference across the capacitor is 145 V. Therefore, the charge stored in the capacitor is:

\(Q = CV = (9.00 × 10^-12 F) × (145 V) = 1.305 × 10^-9 C\)

To find the charge per unit length (λ), we need to divide the total charge by the length of the capacitor, which is given as 15.0 cm in the passage. Therefore:

\(λ = Q / L = (1.305 × 10^-9 C) / (0.15 m) ≈ 8.70 × 10^-9 C/m\)

So, the charge per unit length (λ) on the capacitor when it is charged to 145 V is approximately \(8.70 × 10^-9 C/m.\)

Explanation:

The water level depth of the well is 142 feet, which is roughly about 50 feet.

When a homeowner removes the well cap and drops in an ice cube, and it takes three seconds from releasing the ice cube to hear a splash, the depth of the well's water level is about 50 feet.

The amount of time it takes to hear a splash from an ice cube being dropped into a well can be used to calculate the depth of the well. The formula to calculate the depth of a well is: Depth of well = 16 x time in seconds squared.

If the time it takes to hear the splash is three seconds, we can use this formula to calculate the depth of the well:

Depth of well = 16 x (3 seconds)^2

= 16 x 9

= 144 feet

Therefore, the depth of the well is 144 feet. However, this is the depth of the well from the surface to the bottom. Since we're interested in the depth of the water level, we need to subtract the height of the well cap and assume that the ice cube was dropped from the cap's surface. The typical height of a well cap is about 2 feet. So we subtract 2 feet from 144 feet:

Depth of water level = 144 feet - 2 feet

= 142 feet

Therefore, the depth of the water level in the well is about 142 feet, which is roughly 50 feet.

If angle of incidence and angle of refraction be i   and r respectively ,

sini / sinr = μ ( refractive index )

sin r = sin i / μ

If angle of incidence i be constant and medium becomes denser that means μ becomes higher in value , the value of sin r will be low ( because of increase in value of denominator )

As sin r decreases , r also decreases also.

Hence when medium becomes denser , angle of refraction becomes less .

Orbital velocity of satellite

\(v = \sqrt{ \frac{gm}{r} } \)

Radius of new orbit r' =6r

Thus new orbital velocity of satellite:

\(v = \sqrt{ \frac{gm}{6r} } = \frac{v}{ \sqrt{6} } \)

For satellites in circular orbits, the relationship between orbital velocity and altitude is strict. The task of a satellite launch rocket is to release the satellite at a suitable place in space, with the appropriate speed and direction of movement to put it in the desired orbit.

How a satellite stays in orbit can be thought of in two equivalent ways, both of which explain the relationship between the satellite's altitude and velocity.

The motion of the satellite can be seen as creating a centrifugal force that opposes the gravitational pull. For example, imagine attaching an object to a string and swinging it in a circle. The object is pulling outward against the string, and that outward force (centrifugal force) becomes greater the faster the object swings. At the right speed, the centrifugal force of the satellite due to motion around the earth just balances the gravitational pull, and the satellite remains in orbit.

Answer:

The answer is A

Enthalpy of formation of a substance is defined as the change in enthalpy when one mole of a substance is formed from its constituent elements in their standard states. In the case of vacancies in pure copper, the enthalpy of formation is given as 86.9 kJ/mol.

The fraction of sites vacant at a certain temperature can be determined using the Boltzmann distribution law, which states that the fraction of particles in a system with energy E is proportional to e^(-E/kT), where k is the Boltzmann constant and T is the temperature in kelvin.

To find the fraction of vacant sites, we need to calculate the energy required for a vacancy to form, which is given by the enthalpy of formation. We can then use this energy in the Boltzmann distribution equation to find the fraction of sites that are vacant at a given temperature.

At 1084°C, the temperature in kelvin can be calculated as 1084°C + 273.15 = 1357.15 K. Substituting this value and the enthalpy of formation into the Boltzmann distribution equation gives us the fraction of sites that are vacant.

However, this calculation is only a rough estimate and real systems are more complex. Factors such as the presence of impurities, lattice defects, and external influences can affect the fraction of vacant sites and cannot be accounted for by this simple calculation.

A result, the object is being acted upon by a net downward force of 5N.

The force that is produced by summing the vector sums of all the forces acting on an object is known as the resultant force. The effect of the resulting force is the same as the sum of all the acting forces operating on the object. The direction of the forces must be considered when calculating the resulting force.

The northward force is Fn = 10N, given.

Fs = 15N is the southern force.

The net force on the phone is Fnet =?N, which is necessary.

Downward pressure is applied by the object's weight, and upward pressure is applied by upward resistance. The vector sum of these two forces will represent the net force.

Fnet = Fs - Fn (Considering the direction downward as positive)

Fnet = 15N - 10N

Fnet = 5N

Naoki's mass is 67 kg, due to which the force calculated to pedal is 140.7 N at acceleration of 2.1 m/s².

Newton's second law of motion is a fundamental principle in physics that describes the relationship between force, mass, and acceleration. It states that an object's acceleration is proportional to the force applied to it and inversely proportional to its mass. We can rewrite this equation to find the mass:

F = m * a

where F is the net force applied to an object, m is its mass, and a is the resulting acceleration.

To solve this problem, we can use Newton's second law of motion, which states that the force applied to an object is equal to the product of its mass and acceleration:

F = m * a

where F is the applied force, m is the object's mass, and an is the acceleration.

The second law is mathematically stated as follows:

m = F / a

Substituting the given values, we get:

m = 140.7 N / 2.1 m/s²

m = 67 kg
