If a wave has an amplitude of 0.0800 m and is moving 7.33 m/s. The

wavelength of the wave is 1.69m.

The wavelength of a wave can be determined using the equation:

Wavelength = velocity / frequency

To determine the frequency we need to calculate the reciprocal of the time it takes for one complete oscillation.

frequency = 1 / time

frequency = 1 / 0.230

frequency ≈ 4.35 Hz

Substitute the values into the wavelength equation:

wavelength = velocity / frequency

wavelength = 7.33 / 4.35

wavelength ≈ 1.69m

Therefore the wavelength of the wave is approximately 1.69 meters.

Answer:

The change in momentum is:  \(13.5\,\frac{kg\,m}{s}\)

Explanation:

Let's define that vectors pointing up are positive, and vectors pointing down negative.

Then we express the initial momentum of the ball as the product of its mass times the velocity, and include the negative sign since this momentum is pointing down (velocity vector is pointing down):

\(P_i=-0.5\,(15) \frac{kg\,m}{s} =-7.5\, \frac{kg\,m}{s}\)

the final momentum is positive (pointing up) and given by the product:

\(P_f=0.5\,(12) \frac{kg\,m}{s} =6\, \frac{kg\,m}{s}\)

Therefore, since the change in momentum is defined as the difference between the final momentum minus the initial one, we get:

\(P_f-P_i=6-(-7.5)\,\frac{kg\,m}{s} =13.5\,\frac{kg\,m}{s}\)

Given the distance traveled and time elapsed, the average speed of the train is approximately 26.944m/s.

Speed is simply referred to as distance traveled per unit time.

Mathematically, Speed = Distance ÷ time.

Given the data in the question;

First we convert miles to meters and Hours minutes to seconds.

221 miles = ( 221 × 1609.344 )m = 355665.024 meters

3 hours and 40 minutes = ( 3×60×60)s + ( 40×60)s

= 10800s + 2400s

= 13200s

Now, determine the average speed.

Speed = Distance ÷ time

Speed = 355665.024m / 13200s

Speed = 26.944m/s

Given the distance traveled and time elapsed, the average speed of the train is approximately 26.944m/s.

The traffic cop needs 23.3 seconds to pass the automobile.

When your velocity (not speed) changes, you are accelerating. A automobile moving at a steady 100 km/h in a straight line has no acceleration. Average acceleration is equal to (change in velocity) / (duration). The car's acceleration is zero because its change in velocity is also zero.

\(d1 = v1*t1 = 35.0 m/s * 1 s = 35.0 m\)

\(d = d1 = 35.0 m\)

\(d2 = v2*t + (1/2)at^2\)

\(d2 = (1/2)at^2\)

\(v2*t + (1/2)at^2 = (1/2)at^2\)

\(v2*t = (1/2)at^2\)

The current required for a uniform bar to be in rotational equilibrium when it is at an angle of 30.0° above the horizontal and carrying a current I in a magnetic field B is zero, as the torque acting on the bar is zero at this angle.

To find the current I in the bar for it to be in rotational equilibrium when it is at an angle of 30.0° above the horizontal, we need to use the torque equation for a uniform bar carrying a current I in a magnetic field B:

τ = 1/2 IBL² sinθ

where τ is the torque, I is the current, B is the magnetic field, L is the length of the bar, and θ is the angle of the bar relative to the magnetic field.

Since we want the bar to be in rotational equilibrium, the torque must be zero, so we can set the torque equation equal to zero:

0 = 1/2 IBL² sin30°

Solving for I, we get:

I = 0 / (1/2 B L² sin30°)

I = 0

Therefore, the current required for the bar to be in rotational equilibrium when it is at an angle of 30.0° above the horizontal is zero. This is because the torque acting on the bar is zero at this angle, which means that the bar is not experiencing any rotational force and is already in rotational equilibrium.

All of the given choices are correct definition of what weight of a substance implies.

Weight is the vertical force on a body due to the gravitational attraction or pull.

  Weight  = mass x acceleration due to gravity

Mass of a body is directly proportional to its weight and so also is the gravity.

Mass is the amount of matter within a substance.

Weight is the force of gravity exerted by a body on another or a surface.

The reason why the weight of a body changes from place to place is mainly due to the gravitational pull

The total distance traveled by the object is 3h.

The total distance traveled by the object can be determined by applying the principle of conservation of energy as follows;

Since the object loses half its energy each time it hits the ground.

Hence it will rise half of the previous height each time, as potential energy at height h is given by;

P.E =  mgh

Thus, the object will rise h/2 after the first hit, then h/4 and so on.

Hence the total distance traveled by the object is calculated as follows;

s = h + (h/2 + h/2 + h/4 + h/4 + ---)

s = h + (h + h/2 + ---)

s = h + h(1 + 1/2 + 1/4 + ---)

s = h + h(1 +  (1/1 - 1/2) )

s = 3h

Thus, the total distance traveled by the object is 3h.

Moon has lesser mass as conpared to earth, therefore gravitational force exerted by moon on any object is lesser than that of gravitational force exerted by earth on the same object, hence we can say that astronauts weight less on moon, i.e approximately 1/6 th of their weight on earth.

The minimum initial speed of the proton needed to pass through the square of charges is 5.09 x 10^6 m/s.

Charge is a fundamental physical property of matter that describes the degree to which it interacts with electromagnetic fields. It is an intrinsic property of subatomic particles, such as protons and electrons, that gives rise to electric and magnetic forces.

The basic unit of charge is the Coulomb (C), named after the French physicist Charles-Augustin de Coulomb, who first quantified the electric force between charged objects. A single proton or electron has a charge of approximately 1.6 x 10^-19 Coulombs.

Electric charge is conserved, which means that the total amount of charge in a closed system remains constant over time. Charges can be positive, negative, or neutral, and like charges repel each other, while opposite charges attract each other.

Charge is an important property in many areas of physics, including electromagnetism, quantum mechanics, and particle physics. It is also a crucial concept in many practical applications, such as electronics, power generation, and communication systems.

We can solve this problem using the principle of conservation of energy. The initial kinetic energy of the proton must be equal to the work done by the electrostatic force of the charged spheres on the proton as it passes through the square.

The electrostatic force between two charges q1 and q2 separated by a distance r is given by Coulomb's law:

\(F = k * q1 * q2 / r^2\)

where k is the Coulomb constant, which has a value of

\(8.99 x 10^9 N m^2 / C^2.\)

Since the four spheres are identical and equally spaced, the electrostatic force on the proton due to each sphere will have the same magnitude and direction. We can calculate the force on the proton due to one sphere and multiply by 4 to get the total force:

\(F = 4 * k * q * q_p / r^2\)

where q is the charge on each sphere (+15 nC), q_p is the charge on the proton (-1.6 x 10^-19 C), and r is the distance from the center of the square to the proton's initial position (which we will assume is the same as the distance from the center of the square to the closest sphere, which is sqrt\((2)/2 * 0.02 m = 0.0141 m).\)

The work done by the electrostatic force as the proton passes through the square is:

W = F * d

where d is the length of the square (2 cm = 0.02 m).

Equating the initial kinetic energy of the proton to the work done by the electrostatic force, we get:

\((1/2) * m * v_i^2 = 4 * k * q * q_p * d / r^2\)

where m is the mass of the proton (1.67 x 10^-27 kg) and v_i is the initial speed of the proton.

Solving for v_i, we get:

\(v_i = sqrt(8 * k * q * q_p * d / (m * r^2))\)

Plugging in the values, we get:

\(v_i = sqrt(8 * 8.99 x 10^9 N m^2 / C^2 * 15 x 10^-9 C * 1.6 x 10^-19 C * 0.02 m / (1.67 x 10^-27 kg * (0.0141 m)^2))v_i = 5.09 x 10^6 m/s\)

Therefore, the minimum initial speed of the proton needed to pass through the square of charges is \(5.09 x 10^6 m/s.\)
