For this problem, you will only be concerned with the geometric aspects of thin-film interference, so ignore phase shifts caused by reflection from a medium with higher index of refraction. (Because of the structure of a butterfly's wings, such phase shifts do not contribute much to what you actually see when you look at the butterfly.)

An object of mass 0. 16kg is moving forwards at a speed of 0. 50m/s. A second object of mass 0. 10kg is at rest. 0.375 m/s is the speed of the first object after the collision.

Just apply momentum conservation since the net external force on the system is zero.

0.16 × 0.50 + 0.10 × 0 = 0.10 × 0.50 + 0.16 ×v

0.080 = 0.050 + 0.16v

0.16v = 0.030

v = 0.375 m/s

The initial velocity is the velocity of the item or system prior to the impact. In contrast, final velocity refers to the velocity of the item after the contact. Use the momentum equation p = m•v to compute the momentum or velocity of an item if given the other values. The answer is no for a single pair of equal mass items.

When the drive steps on the accelerator: (a) The magnitude of the force of the car on the truck is 4500 N. (b) The magnitude of the force of the truck on the car is also 4500 N.

What is magnitude?

Magnitude refers to the size or extent of a quantity, property, or phenomenon. It is a measure of the absolute value or scale of something, often expressed as a numerical value or a relative comparison.

Magnitude can be used in various contexts, depending on the specific field or subject matter. Here are a few examples:

Magnitude in Physics: In physics, magnitude often refers to the size or quantity of a physical property, such as the magnitude of a force, velocity, acceleration, electric field, or magnetic field. It represents the numerical value or intensity of the quantity being measured.

Magnitude in Mathematics: In mathematics, magnitude is used to express the size or absolute value of a number or a mathematical object. For example, the magnitude of a real number is its distance from zero on a number line, disregarding its sign. It is typically denoted as the absolute value symbol (|x|).

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this scenario, the force exerted by the car on the truck (action) is equal in magnitude but opposite in direction to the force exerted by the truck on the car (reaction).

(a) The magnitude of the force of the car on the truck is given as 4500 N. This force is applied by the drive wheels of the car pushing backwards against the ground. It is important to note that this force does not depend on the mass of the car or the truck, but rather on the force applied by the driver on the accelerator.

(b) As per Newton's third law, the magnitude of the force of the truck on the car is also 4500 N. This force is a reaction to the force exerted by the car on the truck. Again, this force does not depend on the masses of the car or the truck but is equal in magnitude and opposite in direction to the force exerted by the car on the truck.

Answer:

Volt divided by ampere

Explanation:

V = IR

V/I = R

The unit of resistance from ohms law is volt / ampere. Thus, option A is correct.

Ohm's law states that the applied voltage is directly proportional to the current flow in the conductor. It is written as V ∝ I. It remains constant at room temperature.

V is defined as  potential difference or voltage. The SI unit of voltage is volt(V). I is defined as the current flowing in the circuit. The SI unit of current is ampere (A).

Generally, ohm's law equals to V = IR. R represents resistance of a material which oppose the current flow in the conductor. The unit of resistance is ohm(Ω).

When the potential difference(V) is constant, Resistance is inversely proportional to current. Current increases with decrease of resistance and current decreases with increase of resistance.

To find  equivalent unit of resistance, the ohm's law is :

V = IR

R = V / I

  = volt / ampere.

Hence, the unit of resistance from ohm's law is volt / ampere. The SI unit of resistance is ohm(Ω). Thus, option A is correct.

t = 275 microseconds / 2 = 137.5 microseconds

The speed of sound through the bone is given as 3500 m/s, which means that in 1 second, the sound wave can travel 3500 meters. Therefore, in 137.5 microseconds (0.0001375 seconds), the sound wave can travel:

d = v × t = 3500 m/s × 0.0001375 s = 0.48125 meters

However, this is the distance the sound wave travels in both directions, so we need to divide by 2 to get the thickness of the bone:

a) The population of the qubit in the excited state is given by Pe(t) = A^2 / (A^2 + N^2). b) The maximum value of Pe(t) is 1 when A = N. c) The Rabi frequency is given by ωR = 2A / T.

d) The Rabi frequency can be changed by changing the amplitude of the driving pulse, the detuning between the driving pulse and the qubit's natural frequency.

e) The Rabi frequency can be used to control the qubit's state, to perform quantum gates, and to initialize the qubit's state.

The population of the qubit in the excited state can be calculated as follows:

Pe(t) = |Ce(t)|^2 = A^2 / (A^2 + N^2)

where:

Pe(t) is the population of the qubit in the excited state at time t

A is the amplitude of the driving pulse

N is the qubit's relaxation rate

The maximum value of Pe(t) is 1 when A = N. This is because when A = N, the driving pulse is strong enough to overcome the qubit's relaxation rate and fully excite the qubit.

The Rabi frequency is given by ωR = 2A / T, where T is the period of the driving pulse. This means that the Rabi frequency is proportional to the amplitude of the driving pulse and inversely proportional to the period of the driving pulse.

The Rabi frequency can be changed by changing the amplitude of the driving pulse, the detuning between the driving pulse and the qubit's natural frequency, or the qubit's relaxation rate.

The Rabi frequency can be used to control the qubit's state, to perform quantum gates, and to initialize the qubit's state. For example, if the driving pulse is applied at the qubit's resonant frequency, the Rabi frequency will be maximum and the qubit can be fully excited.

If the driving pulse is applied at a different frequency, the Rabi frequency will be smaller and the qubit will only be partially excited. The Rabi frequency can also be used to perform quantum gates, which are operations that can be used to manipulate the qubit's state.

Finally, the Rabi frequency can be used to initialize the qubit's state to a specific value, such as the ground state or the excited state.

To raise the automobile with a hydraulic lift, a force of approximately 19,000 N must be applied to the piston.

In a hydraulic lift, the principle of Pascal's law is applied, which states that pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container. By utilizing this principle, a smaller force applied to a smaller piston can generate a larger force on a larger piston.

In this scenario, the force needed to lift the automobile can be calculated using the formula:

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

where \(F_{1}\) is the force applied to the piston, \(A_{1}\) is the area of the piston, \(F_{2}\) is the force generated on the larger piston (required to lift the automobile), and \(A_{2}\) is the area of the larger piston.

Given the radius of the shaft (small piston) as 0.08 m and the radius of the piston as 0.01 m, we can calculate the forces applied and generated as follows:

\(A_{1} = \pi (0.08)^2\\A_{2}= \pi (0.01)^2\)

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

Simplifying the equation and substituting the values, we can solve for \(F_{2}\):

\(F_{2}=\frac{F_{1}A_{2}}{A_{1}}\)

Plugging in the values, we find:

\(F_{2}=\frac{F_{1} \pi (0.01)^2 }{ \pi (0.08)^2} \\F_{2}= \frac{F_{1}\times 0.0001}{0.0064} \\F_{2}= 0.015625 \times F_{1}\)

Given that the mass of the automobile is 1520 kg and the acceleration due to gravity is \(9.8 \hspace m/s^{2}\), we can equate \(F_{2}\) to the weight of the automobile:

\(F_{2}= mg\\0.015625\times F_{1}= 1520\times 9.8\)

Solving for \(F_{1}\), we find:

\(F_{1}\approx \frac{1520\times 9.8}{0.015624} \\F_{1} \approx 19072 \hspace N\)

Therefore, a force of approximately 19,000 N must be applied to the piston in order to raise the automobile using the hydraulic lift.

The car will appear to be 10% lighter than its normal weight when traveling at a speed of about 16.7 m/s.

When the car is going over the top of the hill, the apparent weight of the occupants will be less than their actual weight due to the centrifugal force acting on them.

The centrifugal force acting on the occupants is given by:

Fc = ma

where Fc is the centrifugal force, m is the mass of the occupants, and a is the centripetal acceleration.

The centripetal acceleration is given by:

a = v^2 / r

where v is the velocity of the car and r is the radius of the hill.

The apparent weight of the occupants can be found using:

Wapp = Wactual - Fc

where Wactual is the actual weight of the occupants and Wapp is the apparent weight.

If the occupants appear to weigh 10% less than their average weight, then:

Wapp = 0.9 * Wactual

Substituting the equations for F and a we get:

0.9 * Wactual = Wactual - m * v^2 / r

Simplifying, we get:

m * v^2 / r = 0.1 * Wactual

v^2 = 0.1 * Wactual * r / m

We can express the weight in terms of mass using the formula:

W = m * g

where W is the weight, m is the mass, and g is the acceleration due to gravity.

Substituting, we get:

v^2 = 0.1 * m * g * r / m

v^2 = 0.1 * g * r

Solving for v, we get:

v = √(0.1 * g * r)

Plugging in the values, we get:

v = √(0.1 * 9.81 m/s^2 * 350 m)

v = 16.7 m/s

Therefore, the velocity of the car at which the occupants will appear to weigh 10% less than their average weight is approximately 16.7 m/s.

where y is the final vertical position, y0 is the initial vertical position, v0y is the initial vertical velocity, g is the acceleration due to gravity, and t is the time.

In this case, we want to find the time it takes for the keys to hit the ground, so y = 0. The initial vertical position is 64 m, the initial vertical velocity is 0 (since the keys were thrown horizontally), and the acceleration due to gravity is -9.8 m/s^2.

Plugging these values into the equation, we get:
0 = 64 + 0*t + 0.5*(-9.8)*t^2

Simplifying and rearranging, we get:
4.9*t^2 = 64
t^2 = 64/4.9
