Answer with Explanation:

Concepts and reasoning

The principle for addressing this question is that a capacitor in an RC circuit allows current to flow until fully charged. Once charged, it prevents any further current from moving through. Conversely, the situation is different with an inductor in an RL circuit. In accordance with Faraday's law, an inductor generates an electromagnetic force to counteract the applied voltage, but when no change in flux occurs, it behaves akin to a regular wire as if the inductor is absent.

In the accompanying diagram, a resistor is connected in series with a capacitor.

As we observe

The greatest mass that can hang without submerging is 2.93 kg. The provided details are as follows: sphere diameter = 20 cm, hence the radius r = 10 cm = 0.10 m. The density of the Styrofoam sphere is 300 kg/m³. The sphere's volume calculates to 4.18 * 10⁻³ m³. Mass M = Density * Volume results in (300)(4.18 * 10⁻³ m³) = 1.25 kg. The displaced water mass is computed as volume * water density, yielding 4.18 * 10⁻³ m³ * 1000 = 4.18 kg. The additional mass the sphere can hold is the difference between the two mass calculations: 4.18 kg - 1.25 kg = 2.93 kg.

Response:

(a) 104 N

(b) 52 N

Provided Information

Incline angle of the ramp: 20°

F forms a 30° angle with the ramp

The parallel component of F along the ramp is Fx = 90 N.

The perpendicular component of F is Fy.

(a)

Consider the +x direction pointing up the slope, and the +y direction perpendicular to the ramp's surface.

Using the Pythagorean theorem, decompose F into its x-component:

Fx=Fcos30°

To find F:

F= Fx/cos30°

Insert the value for Fx based on the given info:

Fx=90 N/cos30°

   =104 N

(b) Calculate the y-component of r using the Pythagorean theorem:

     Fy = Fsin 30°

Substituting for F from part (a):

     Fy = (104 N) (sin 30°)  

          = 52 N

During the initial phase, the rocket accelerates at

over a time interval of

The final velocity after this period is found using the SUVAT formula:

with initial velocity u = 0. Substituting a1 and t1 gives:

Afterward, the rocket decelerates uniformly at

until it stops, meaning the final velocity is

Again using the SUVAT formula,

and knowing , solve for t2, the time until the rocket halts:

2) 299.9 m

Calculate distances covered in both phases.

Distance in the first phase:

Substituting values from part 1,

Distance in the deceleration phase:

Substituting known values,

Total distance traveled is

d = 82.7 m + 217.2 m = 299.9 m
