A shell is fired on level ground with an initial velocity of 50.0 m/s at an angle of 64.0° above the horizontal. By analyzing the projectile motion, we can determine various quantities related to its motion. The initial velocity has horizontal and vertical components, and we can calculate them using trigonometry.

The time it takes for the shell to reach its highest point can be found by considering the vertical motion and using the kinematic equation. The maximum height above the ground can be determined by finding the vertical displacement at the highest point. The horizontal distance the shell lands from its firing point can be calculated by considering the horizontal motion and using the time of flight.

At the highest point, the vertical component of the shell's velocity becomes zero, while the horizontal component remains constant. The acceleration at the highest point has only a vertical component due to the influence of gravity.

To find the horizontal and vertical components of the shell's initial velocity, we can use trigonometry. The horizontal component is given by \(v_0x = v_0 * cos\)θ, where v₀ is the initial velocity and θ is the angle of elevation. The vertical component is given by \(v_0y = v_0 * sin\)θ.

The time it takes for the shell to reach its highest point can be found by analyzing the vertical motion. The vertical component of velocity decreases due to the acceleration of gravity until it becomes zero at the highest point. Using the equation \(v_y = v_0y - g * t\), where \(v_y\) is the vertical component of velocity, g is the acceleration due to gravity (approximately 9.8 m/s²), and t is the time, we can solve for the time it takes to reach the highest point.

The maximum height above the ground can be determined by finding the vertical displacement at the highest point. Using the kinematic equation \(y = y_0 + v_0yt - (1/2) * g * t^2\), where y is the displacement in the vertical direction, y₀ is the initial vertical position (zero in this case), v₀y is the initial vertical velocity, g is the acceleration due to gravity, and t is the time to reach the highest point, we can calculate the maximum height.

The horizontal distance the shell lands from its firing point can be calculated by considering the horizontal motion and using the time of flight. The time of flight can be found by using the equation \(t = 2 * v_0y / g\). Multiplying the time of flight by the horizontal component of velocity, we can determine the horizontal distance traveled.

At the highest point, the vertical component of the shell's velocity becomes zero, while the horizontal component remains constant. The acceleration at the highest point is solely due to gravity and has only a vertical component, which is -g.

To determine the horizontal and vertical components of the shell's velocity at the highest point, we can use the fact that the vertical component becomes zero while the horizontal component remains constant. Thus, the horizontal component of the velocity at the highest point is the same as the initial horizontal component, and the vertical component is zero.

The frequency of 20-mm microwaves is approximately 1.5 × 10^10 Hz. (c = 3.0 × 108 m/s) .

The frequency of microwaves with a wavelength of 20 mm, we can use the wave equation:

c = λ * ν

Where:

c = speed of light (3.0 × 10^8 m/s)

λ = wavelength

ν = frequency

First, we need to convert the wavelength from millimeters to meters:

λ = 20 mm = 20 × 10^(-3) m

Now, we can rearrange the equation to solve for the frequency (ν):

ν = c / λ

Substituting the values:

ν = (3.0 × 10^8 m/s) / (20 × 10^(-3) m)

ν = (3.0 × 10^8) / (20 × 10^(-3))

ν = 1.5 × 10^10 Hz

a) On a wet basis, the molar composition of the gas is approximately 0.813 mol propane, 0.055 mol n-butane, and 0.132 mol water. The ratio of mol H₂O to mol dry gas is 0.162 mol H₂O/mol dry gas.

b) The required air feed rate is approximately 65.9 kmol/h. If the combustion were only 65% complete, the required air feed rate would increase to approximately 101.4 kmol/h.

a) To calculate the molar composition on a wet basis, we convert the weight percentages to mole fractions using the molar masses of propane, n-butane, and water. The molar composition is determined by dividing the weight percentage by the respective molar mass and normalizing the values to sum up to 1. The ratio of mol H₂O to mol dry gas is determined by dividing the mol water by the sum of mols of propane and n-butane.

b) To calculate the required air feed rate, we use the stoichiometry of the combustion reaction between butane and air. The balanced equation shows that 1 mol of butane reacts with 13.5 mol of air. Considering the 25% excess air requirement, we multiply the stoichiometric air requirement by 1.25. If the combustion is only 65% complete, the remaining butane requires additional air to achieve complete combustion. Therefore, the required air feed rate increases to account for the unreacted butane.

A parallel plate capacitor of capacitance C is discharged through a resistor of resistance R. The total energy discharged by the capacitor is (1/2)CV(0), which for C = 1 microfarad and V(0) = 10 volts, is 0.5 microjoules.

a) The circuit consists of a parallel plate capacitor of capacitance C connected in series with a resistor of resistance R. The differential equation describing the discharge is given by dq/dt = -q/RC, where q is the charge on the capacitor and RC is the time constant of the circuit. Solving this differential equation gives q(t) = q(0)exp(-t/RC), where q(0) is the initial charge on the capacitor. The current through the circuit is then given by i(t) = dq(t)/dt = -q(0)/RC * exp(-t/RC), and i(0) = -V(0)/R, where V(0) is the initial voltage across the capacitor.

b) The energy discharged per unit time is dE/dt = Ri(t), where R is the resistance of the circuit and i(t) is the current through the circuit at time t. The total energy E discharged by the capacitor through the resistor R is given by integrating dE/dt over time, which gives E = (1/2)CV(0), where V(0) is the initial voltage across the capacitor.

c) Since the same amount of energy that is discharged from the capacitor is stored in it during the charging process, the amount of energy that needs to be tapped at the source while charging the capacitor is also (1/2)CV(0).

d) For C = 1 microfarad and V(0) = 10 volts, the total energy stored in the capacitor is E = (1/2)CV(0) = (1/2)*(1 microfarad)*(10 volts)^2 = 0.5 microjoules.

The equation for the magnitude of the angular acceleration α is α = rF / (3mR^2) where r represents the radius of the spheres, F is the applied force, m is the mass of each sphere, and R is the distance between the center of the cylinder and the center of each sphere.

This equation is derived from the rotational dynamics of the system. The torque τ exerted by the force F is given by τ = rF, where r is the lever arm or radius at which the force is applied. The moment of inertia I of the system is given by I = 2mR^2, considering the two spheres of mass m and distance R.

Using Newton's second law for rotational motion, τ = Iα, and substituting the values, we get rF = 2mR^2 α. Solving for α, we find α = rF / (2mR^2). However, since there are two spheres, we divide by 2 to obtain α = rF / (3mR^2), as stated in the given equation.
