If the engine of a boat on a river is turned off while the boat is moving with a steady speed, several things would happen Loss of propulsion,Drifting,Loss of steering control and Potential hazards.

Loss of propulsion: Without the engine running, the boat would lose its power source for propulsion. The boat would gradually slow down and eventually come to a stop unless other external forces, such as currents or wind, continue to move it.

Drifting: Once the boat comes to a stop, it would start to drift with the current of the river or be affected by wind forces. The direction and speed of the drift would depend on the strength and direction of the current or wind.

Loss of steering control: When the engine is turned off, the boat's steering mechanism, such as a rudder, would also lose power. Without the ability to steer, the boat would follow the course determined by the river's current or the wind direction.

Potential hazards: Depending on the surroundings and the current conditions, there could be potential hazards for a boat that is no longer under power. These hazards might include other vessels, obstacles, shallow areas, or strong currents. The boat's crew would need to take appropriate actions to ensure the safety of the boat and its occupants.

It's important to note that the specific behavior of the boat after the engine is turned off can vary depending on factors such as the size and design of the boat, the strength and direction of the current, and the presence of wind or other external forces.

The REE decreases as a person ages, indicating a decrease in metabolism and muscle mass.

To investigate how calorie prerequisites change as an individual progresses in years, we can utilize the information table that shows the assessment of the day to day resting energy use (REE). We should pick a female grown-up with a load of 70 kg for instance.

Utilizing the Harris-Benedict condition, we can compute the REE for the grown-up at each age range:

Age 18-29:

REE = (447.593 + (9.247 x load in kg) + (3.098 x level in cm) - (4.330 x age)) x 1.0 (female)

= (447.593 + (9.247 x 70) + (3.098 x 165) - (4.330 x 25)) x 1.0

= 1565.14 calories/day

Age 30-60:

REE = (88.362 + (13.397 x load in kg) + (4.799 x level in cm) - (5.677 x age)) x 1.0 (female)

= (88.362 + (13.397 x 70) + (4.799 x 165) - (5.677 x 45)) x 1.0

= 1437.45 calories/day

More than 60:

REE = (447.593 + (8.126 x load in kg) + (3.481 x level in cm) - (4.938 x age)) x 1.0 (female)

= (447.593 + (8.126 x 70) + (3.481 x 165) - (4.938 x 65)) x 1.0

= 1263.95 calories/day

As the individual ages, the REE diminishes. The assessed REE for a grown-up at age 18-29 is 1565.14 calories/day, while the assessed REE for a grown-up more than 60 is 1263.95 calories/day.

These outcomes show that the body's digestion changes over the long haul and turns out to be less effective at consuming calories. Maturing likewise prompts a decline in bulk, which further adds to the diminishing in REE.

Hence, as individuals progress in years, they might have to change their calorie admission to keep a solid weight and stay away from weight gain.

Explanation:

The frequency at which the capacitive reactance is 375 ω and the Capacitance of 3.25 μF is 131 s⁻¹.

Capacitance is the ability or capacity of the substance to collect and store electrical energy and the unit of capacitance is Farad (F). Capacitive reactance is the term that measures the opposition to current flow in the AC circuits and the unit of capacitive reactance is the ohm(Ω).

From the given,

The capacitive reactance (Xc) = 375ω

capacitance (C) = 3.25μF

capacitive reactance Xc = 1/(2π×f×C)

Frequency (f) = 1/(2π×Xc×C)

                     = 1/(2×3.14×375×3.25×10⁻⁶)

                     = 131 s⁻¹.

The magnitude of the tension in the rope is 12.2625 N, and the rope is being pulled horizontally to the left by the wind force..

What is tension?

Tension is the force transmitted through a string, rope, cable or wire when it is pulled tight by forces acting on it from opposite ends. It is a force that is directed along the length of the string, rope, cable or wire and is always directed away from the object that is creating the tension.

When an object is suspended from a rope or cable, the tension in the rope or cable must be equal to the weight of the object in order for the object to remain stationary or move at a constant velocity. If the tension is less than the weight of the object, the object will fall, and if the tension is greater than the weight of the object, the object will rise.

Tension plays an important role in many areas of physics and engineering, such as in the design of suspension bridges, elevator systems, and the motion of satellites in orbit.

To find the tension in the rope and the rope's angle from the vertical, we can start by drawing a free body diagram of the object:

       Tension (upwards)

                   |

                   |

                   |

                   |

        Weight (downwards)

                   |

                   |

                   |

                   |

Wind force (to the right)

where Tension is the tension in the rope, Weight is the weight of the object, and Wind force is the horizontal force due to the wind.

The object is in equilibrium, so the net force on it is zero. We can write two equations based on the forces in the vertical and horizontal directions:

Vertical equilibrium:

             Tension - Weight = 0

                Tension = Weight

Horizontal equilibrium:

   Wind force = Tension * sin(theta)

where theta is the angle between the rope and the vertical.

We can solve these equations for the tension and theta:

Weight = m * g = 1.25 kg * 9.81 m/s^2 = 12.2625 N

Tension = Weight = 12.2625 N

sin(theta) = Wind force / Tension = 18.3 N / 12.2625 N = 1.492

Since sin(theta) is greater than 1, there is no solution for theta. This means that the rope is not making an angle with the vertical, and is instead being pulled directly to the left by the wind force.

Therefore, the magnitude of the tension in the rope is 12.2625 N, and the rope is being pulled horizontally to the left by the wind force.

Jonathan needs to maintain a separation of 0.543 mm between the plates to get the desired charge, and a dielectric constant of 92.6 to achieve a separation of 5 mm with a dielectric.

(a) Using the equation Q = CV, where Q is the charge, C is the capacitance, and V is the voltage, we can solve for the capacitance: C = Q/V =\((8.15 x 10^-9 C) / (50 V) = 1.63 x 10^-10 F.\)

Then, using the formula for capacitance of parallel plate capacitors: C = ε0A/d, where ε0 is the permittivity of free space, A is the area of the plates, and d is the separation distance, we can solve for the separation distance: d =\(_{3}OA/C = (8.85 x 10^-12 F/m) x (0.01 m^2) / (1.63 x 10^-10 F) = 0.543 mm.\)

(b) To find the dielectric constant, we can use the formula for capacitance of a parallel plate capacitor with a dielectric: C = εrε0A/d, where εr is the relative permittivity or dielectric constant of the material. Solving for εr, we get: εr = Cd / ε0A = \((1.63 x 10^-10 F)\) x (0.005 m) / \((8.85 x 10^-12 F/m)\) x \((0.01 m^2)\) = 92.6.

Therefore, Jonathan should use a dielectric with a relative permittivity of 92.6 to achieve a separation of 5 mm.

Answer: 8.62

Explanation: It’s correct answer:)

Answer:

a)  F = 64.30 N,  b) θ = 121.4º

Explanation:

Forces are vector quantities so one of the best methods to add them is to decompose each force and add the components

let's use trigonometry

Force F1

          sin 170 = F_{1y} / F₁

          cos 170 = F₁ₓ / F₁

          F_{1y} = F₁ sin 170

          F₁ₓ = F₁ cos 170

          F_{1y} = 100 sin 170 = 17.36 N

          F₁ₓ = 100 cos 170 = -98.48 N

Force F2

          sin 30 = F_{2y} / F₂

          cos 30 = F₂ₓ / F₂

          F_{2y} = F₂ sin 30

          F₂ₓ = F₂ cos 30

          F_{2y} = 75 sin 30 = 37.5 N

          F₂ₓ = 75 cos 30 = 64.95 N

the resultant force is

X axis

          Fₓ = F₁ₓ + F₂ₓ

          Fₓ = -98.48 +64.95

          Fₓ = -33.53 N

Y axis

         F_y = F_{1y} + F_{2y}

         F_y = 17.36 + 37.5

         F_y = 54.86 N

a) the magnitude of the resultant vector

let's use Pythagoras' theorem

         F = Ra Fx ^ 2 + Fy²

         F = Ra 33.53² + 54.86²

         F = 64.30 N

b) the direction of the resultant

let's use trigonometry

        tan θ’= F_y / Fₓ

        θ'= \(tan^{-1} \frac{F_y}{F_x}\)

        θ'= tan⁻¹ (54.86 / (33.53)

        θ’= 58.6º

this angle is in the second quadrant

The angle measured from the positive side of the x-axis is

        θ = 180 -θ'

        θ = 180- 58.6

        θ = 121.4º

The correct answer is C. A new substance forms when the batter is cooked.

Explanation:

When a chemical change occurs the properties, and composition of substances change. This means atoms in the substance re-arrange to form a new substance. This only occurs when there is a chemical change, but not when physical changes occur, indeed a physical change only affects the state of the matter, shape, size, etc.

In the case of the pancake, this is an example of a chemical change because though the process of cooking the pancake changes its composition. Due to this, the properties of the cooked pancake, and the butter are not the same as a new substance forms. Also, in this and most chemical changes, reversibility is not possible, that is why you cannot reverse the process and make the cooked pancake batter once again.

Answer:

v = [√(g/2h)]L

Explanation:

Let v be the initial horizontal velocity, t be the time James Bond uses to jump over the ledge of length, L.

So, vt = L and t = L/v

Also, since James Bond has no initial horizontal velocity, he falls freely through the distance, h so we use the equation y - y' = ut - 1/2gt², where y = 0 (at the top of the cliff) and y' = -h, u = 0 (initial vertical velocity), g = acceleration due to gravity = 9.8 m/s² and t = the time it takes to jump off the cliff = L/v.

Substituting these values into the equation, we have

y' - y = ut - 1/2gt²

-h - 0 = 0 × t - 1/2g(L/v)²

-h  = - 1/2gL²/v²

v² = gL²/2h

taking square root of both sides, we have

v = [√(g/2h)]L

So, James Bond's minimum horizontal speed is v = [√(g/2h)]L
