The ocean ridge system is divided into segments that are separated by transform faults and fracture zones.

Transform faults are areas where two tectonic plates slide past one another horizontally, as opposed to fracture zones, which are regions where the crust is broken but there is little to no movement between the plates. The various parts of the ocean ridge system are divided by transform faults or fracture zones. These fracture zones and transform faults have the ability to lateral move the mid-ocean ridge in relation to one another. The segments of the ridge system, which are frequently parallel to one another, are divided by these transform faults or fracture zones, which can give the mid-ocean ridge system a zigzag appearance on a map.

An airplane is flying with a velocity of 42 m/s at a standard altitude of 3 km. At a point on the wing, the airflow velocity is 88 m/s. The  pressure at the point on the wing is  \(P = 6.96 * 10^4 N/m^2\).

To calculate the pressure at a point on the wing, we can use Bernoulli's equation, which relates the pressure, velocity, and density of a fluid in steady, incompressible flow.

The equation is as follows:

P + 1/2 * ρ * \(V^2\) = constant

where P is the pressure, ρ is the density of the fluid, and V is the velocity of the fluid.

Given:

\(P_1 = 7.01 * 10^4 N/m^2\) (pressure at standard altitude)

ρ = \(0.909 kg/m^3\) (density of the fluid)

\(V_1 = 42 m/s\) (velocity of the airplane)

\(V_2 = 88 m/s\) (velocity at the point on the wing)

To find the pressure at the point on the wing, we can use Bernoulli's equation for the standard altitude and the point on the wing, and then solve for P:

\(P_1 + 1/2\) * ρ * \(V_1^2\) = \(P + 1/2\)  * ρ * \(V_2^2\)

Substituting the given values:

\(7.01 * 10^4 + 1/2 * 0.909 * 42^2 = P + 1/2 * 0.909 * 88^2\)

Simplifying the equation:

\(7.01 × 10^4 + 1/2 * 0.909 * 1764 = P + 1/2 * 0.909 * 7744\)

7.01 × 10^4 + 804.906 = P + 3526.242

\(P + 4329.148 = 7.01 *10^4\)

\(P = 7.01 * 10^4 - 4329.148\)

\(P = 6.96 * 10^4 N/m^2\)

Therefore, the pressure at the point on the wing is \(P = 6.96 * 10^4 N/m^2\)

When the stone reaches its highest point, it is neither gaining nor losing speed because the acceleration of the stone at that instant is 0.

At the highest point of its trajectory, the stone momentarily stops and changes direction, going from moving upward to moving downward. The acceleration is the rate of change of velocity, and at this point, the velocity is changing from upward to downward. Since the stone is changing direction, the velocity is changing, but the speed remains constant. This means that the stone's acceleration is 0, and therefore it is neither gaining nor losing speed.

In this situation, the net force acting upon the stone is still equal to its weight, mg. However, this is not the reason why the stone is neither gaining nor losing speed. The stone's velocity and the net force exerted upon the stone are not at a 90-degree angle, so option (c) is incorrect.

The statement about the stone following a parabolic trajectory and the peak of the trajectory having zero slope is true, but it does not explain why the stone is neither gaining nor losing speed at the highest point.

B. Two ends of a bulb are attached to the positive and negative poles of the battery

Explanation:

a) The oscillator frequency is 2.86 x 107 Hz. b)  the kinetic energy (in eV) of the proton is 14.3 eV.

a) The oscillator frequency of the proton in the cyclotron can be determined by the equation:

f = qB/(2πm),

where q is the charge of the proton, B is the magnitude of the magnetic field, and m is the mass of the proton. Substituting the given values, we get:

f = (1.60 x 10-19C)(1.40 T)/(2π x 1.67 x 10-27 kg)

  = 2.86 x 107 Hz.

b) The kinetic energy of the proton can be determined by the equation:

Ek = qV,

where q is the charge of the proton and V is the velocity of the proton. Using the equation for velocity in a circular path,

V = 2πr/T,

where r is the radius of the circle and T is the oscillator frequency, we get:

Ek = (1.60 x 10-19C)(2π x 0.380 m)/(2.86 x 107)

= 2.28 x 10-15 J.

Converting to eV, we get:

2.28 x 10-15 J x (1 eV/1.6 x 10-19 J) = 14.3 eV.

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.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Pressure is force per unit area so,

pressure = 420/.25

Answer:

6.9 m/s

Explanation:

The acceleration due to gravity on another planet is multiplied by your mass to calculate your weight on that planet. The acceleration due to gravity is different on each planet, so your weight will also be different. For example, the acceleration due to gravity on Earth is 9.8 m/s², while the acceleration due to gravity on Mars is 3.711 m/s². This means that if you weigh 100 pounds on Earth, you would weigh only 37.11 pounds on Mars.

The formula for calculating your weight on another planet is:

Weight = Mass * Acceleration due to gravity

For example, if you weigh 100 pounds on Earth and you want to calculate your weight on Mars, you would use the following formula:

Weight on Mars = 100 pounds * 3.711 m/s²

Weight on Mars = 371.1 pounds

Therefore, your weight on Mars would be 371.1 pounds.

The normal stress on an inclined plane at 25 degrees can be calculated using σ = F / A * cos²θ, while the maximum normal stress is σ_max = F / A_max.

a. To calculate the normal stress developed on an inclined plane, we use the formula: σ = F / A * cos²θ. Given that the diameter of the rod is 12 inches, the radius (r) is half of the diameter, which is 6 inches or 0.5 feet. The cross-sectional area of the rod (A) can be calculated using the formula for the area of a circle: A = π * r². Substituting the values, we get A = π * (0.5)^2 = π * 0.25 = 0.7854 square feet.

Now, we can calculate the normal stress using the given axial tensile load (F) of 60 kips and the angle (θ) of 25 degrees. Since the load is given in kips (1 kip = 1000 pounds), we convert it to pounds by multiplying by 1000: F = 60 * 1000 = 60000 pounds.

Using the formula σ = F / A * cos²θ, we substitute the values and calculate the normal stress:

σ = 60000 / 0.7854 * cos²25 ≈ 95317.91 psi (pounds per square inch).

b. The maximum normal stress in the rod occurs when the inclined plane is aligned with the maximum cross-sectional area. In this case, the maximum cross-sectional area (A_max) is the same as the cross-sectional area of a circle, which is π * r². Substituting the radius value, we get A_max = π * (0.5)^2 = π * 0.25 = 0.7854 square feet.

To calculate the maximum normal stress (σ_max), we use the formula σ_max = F / A_max. Substituting the given axial tensile load (F) of 60 kips and the maximum cross-sectional area (A_max), we calculate the maximum normal stress:

σ_max = 60000 / 0.7854 ≈ 76448.44 psi (pounds per square inch).

Therefore, the normal stress developed on an inclined plane at an angle of 25 degrees with the cross section of the rod is approximately 95317.91 psi, and the maximum normal stress developed in the rod is approximately 76448.44 psi.

Inelastic collision and a host of other factors causes the loss of energy.

Kinetic energy of an object is the energy that it possesses due to motion.

It can be defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. When it has gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

In an inelastic collision which is the case of ball X and Y, the kinetic energy of the system is not conserved. The energy that you find lost has been dissipated as other forms of energy. This can be heat, friction, vibrational energy transferred to atoms of the colliding particles, energy lost to deform the atomic structure etc.

In conclusion, the inelastic collision nature of the two balls results in the loss of energy through different forms.
