The direction of the resultant acceleration is 17° North of West. The correct answer is D. The first step is to break down the forces into their horizontal and vertical components.

The eastward force from the ocean tide is purely horizontal, while the wind force has both horizontal and vertical components. To find the horizontal component, we use the cosine of the angle between the force and the horizontal axis:
1500 N * cos(45°) = 1060 N

To find the vertical component, we use the sine of the angle:
1500 N * sin(45°) = 1060 N

So the total horizontal force acting on the sailboat is:
4500 N + 1060 N = 5560 N

And the total vertical force is:
1060 N

To find the direction of the resultant acceleration, we can use trigonometry to find the angle that the acceleration vector makes with the horizontal axis. The tangent of this angle is equal to the vertical component of the acceleration divided by the horizontal component:
tan(θ) = 1060 N / 5560 N

θ = tan^-1(1060/5560) = 10.9°

Therefore, the direction of the resultant acceleration is 17° North of West. The correct answer is D.

As a planet orbits a star, it makes a big ellipse, but its gravity has a similar effect on the star, causing the star to make a small star. This is called the "gravitational wobble" or "stellar wobble".

As a planet orbits a star, it follows an elliptical path due to the gravitational pull of the star. The shape of the planet's orbit is determined by the balance between the gravitational force of the star and the planet's own motion. However, the planet's gravity also affects the star, causing it to move slightly in response to the planet's pull. This motion of the star is much smaller than that of the planet, but it is still measurable and can be observed. This phenomenon is known as the planet's gravitational influence on the star, which causes the star to wobble slightly. This effect is used by astronomers to detect and study exoplanets orbiting distant stars.

The phenomenon that occurs when a planet orbits a star, causing both the planet and the star to make elliptical motions due to their mutual gravitational effects.

This phenomenon is known as the "wobble" or "stellar wobble" and is caused by the gravitational interaction between a planet and its star. As a planet orbits a star, it exerts a gravitational force on the star, causing it to move slightly in response. This movement results in a small, periodic shift in the star's spectral lines, which can be detected by astronomers.

By analyzing this shift, astronomers can determine the presence, size, and orbital characteristics of planets around other stars. At the same time, the planet's gravity also affects the star, causing the star to make a smaller elliptical motion in response. This mutual gravitational interaction results in the observed stellar wobble.

By applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.

The distance between the second charge and the third charge is given as;

r = 0.3 m

\(F_{2} = \frac{kq_2q_3}{r^2} \\\\F_{2}= \frac{(8.99\times10^9) (7.7 \times 10^{-6})(5.9\times 10^{-6}) }{0.3^2} \\\\F_2 = 4.54\ N\)

The net force on particle q₁ is determined by summing the individual forces together;

F(net) = F₁ + F₂

F(net) = -14.4 + 4.54

F(net) = -9.86 N

Thus, by applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.

The force on the box is 2 N.

In this experiment, marbles were rolled down a ramp to determine the relationship between potential and kinetic energy and how it affects the distance a box will slide.

The potential energy of the marbles differed based on their starting location, with higher locations possessing more potential energy. As the marbles rolled down the ramp, their potential energy decreased while their kinetic energy increased.

When the marble hit the box, it transferred its kinetic energy to the box, causing it to slide backward. The results showed that the higher the marble's potential energy, the further the box slid.

Additionally, the larger the mass of the marble, the greater its kinetic energy and the further the box slid. Overall, the hypotheses for each experiment were confirmed by the data collected.

The deceleration of the car is approximately -5 m/s^2.

To calculate the deceleration of the car, we need to first convert the speed from kilometers per hour (km/h) to meters per second (m/s) since the standard unit of acceleration is meters per second squared (m/s^2).

Given:

Speed = 54 km/h

Time taken to stop = 3 s

To convert the speed from km/h to m/s, we can use the conversion factor: 1 km/h = 1000 m/3600 s.

Speed in m/s = (54 km/h) * (1000 m/3600 s)

= 15 m/s

Now, we can calculate the deceleration using the equation of motion:

Deceleration = (Final velocity - Initial velocity) / Time

Since the car comes to a stop, the final velocity is 0 m/s and the initial velocity is 15 m/s.

Deceleration = (0 m/s - 15 m/s) / 3 s

= -15 m/s / 3 s

= -5 m/s^2

The negative sign indicates that the deceleration is in the opposite direction of the initial velocity, which means the car is slowing down.

The Earth must absorb a certain amount of energy when a meteoroid with a mass of 783,000 kg impacts at a speed of 39 km/s. the TNT equivalent of the energy absorbed by the Earth from this meteoroid is approximately 109.73 kilotons.

To calculate the energy absorbed by the Earth, we can use the kinetic energy formula:\(E = (1/2)mv^2\), where E is the energy, m is the mass, and v is the velocity. Plugging in the given values, we have \(E = (1/2) * 783,000 kg * (39,000 m/s)^2\). Simplifying the equation, we find that the energy is approximately \(4.58817 * 10^1^4\)joules.

To determine the TNT equivalent of this energy, we divide the energy by the energy released by one kiloton of TNT, which is \(4.184 * 10^1^2\) joules. Doing the calculation, we find that the TNT equivalent of the energy absorbed by the Earth from this meteoroid is approximately 109.73 kilotons.

Explanation:

Geothermal energy is the thermal energy generated and stored in the Earth.

Explanation:

An IC engines means an Internal Combustion engine. Here, the combustion takes place in side a chamber or a cylinder internally, hence it is known as internal combustion engine.

Combustion is the process where oxygen reacts with the fuel and it burns to produce a large amount of force and heat. In each revolution of the crank, the engine creates a power stroke when the piston goes from the bottom dead center to the top dead center.

During each power stroke, the energy released forces the piston down and the crankshaft is rotated.

The effective external resistance of the circuit is 3.5 ohms, the current in the circuit is 1.71 A, the lost voltage in the battery is 1.285 V, and the current in one of the 3-ohm resistors is 1.71 A.

To solve this problem, we can use Kirchhoff's circuit laws and Ohm's law.

First, let's calculate the equivalent resistance of the parallel combination of two 3-ohm resistors:

1/Rp = 1/3 + 1/3

Rp = 1.5 ohm

Now, let's calculate the total external resistance of the circuit:

R = 2 + Rp

R = 2 + 1.5

R = 3.5 ohm

Using Ohm's law, we can calculate the current in the circuit:

V = IR

I = V/R

I = 6/3.5

I = 1.71 A

The lost voltage in the battery is given by:

VL = E - Ir

VL = 23 - 1.711.5

VL = 1.285 V

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

By plugging in the values and performing the calculations, we can determine the density of Ida is approximately 0.0057 g/cm^3.

To calculate the density of Ida, we need to find its volume first and then divide its mass by the volume. We are given the mass of Ida as 4.3x10^16 kg and the average radius as 15.7 km.

Step 1: Convert the radius to meters (1 km = 1000 meters).

Radius of Ida (r) = 15.7 km = 15.7 x 1000 meters = 15,700 meters.

Step 2: Calculate the volume of Ida using the formula for the volume of a sphere.

Volume (V) = (4/3) x π x r^3

V = (4/3) x 3.14159 x (15,700)^3

V ≈ 7.52 x 10^12 m^3

Step 3: Convert the volume to cubic centimeters (1 m^3 = 1,000,000 cm^3).

Volume (V) ≈ 7.52 x 10^12 m^3 = 7.52 x 10^12 x 1,000,000 cm^3 ≈ 7.52 x 10^18 cm^3

Step 4: Calculate the density of Ida by dividing its mass by its volume.

Density = Mass / Volume

Density = 4.3 x 10^16 kg / 7.52 x 10^18 cm^3 ≈ 0.0057 g/cm^3

Finally we get the density of Ida is approximately 0.0057 g/cm^3.
