Hurricanes are more destructive than tornadoes due to the large area affected and the long attack duration.

A hurricane is a storm that forms over the ocean with winds up to 74 mph. The storm is accompanied by rain, lightning, and thunder and occurs within a few days to a month. Meanwhile, tornadoes only occur in the span of about a few seconds to an hour.

Wind speeds generated by a hurricane are 131 miles per hour or more, less than a tornado which has wind speeds of more than 207 miles per hour. But the Hurricane attack area is quite wide, which is about 300 miles. The center of the storm itself was 20 to 40 miles wide. Whereas a tornado strikes only about 500 feet and will recede at a distance of about 5 miles before finally stopping.

23674 N is the amount of magnitude frictional force required to bring the locked-together automobiles to a complete stop.

Magnitude is simply referred to in physics as "distance or quantity." It shows the size or direction that an object moves in either an absolute or relative sense.

A magnitude can be defined as a quantity's size in simple terms. For instance, the Richter scale's measurement of an earthquake's magnitude, which identifies the earthquake's size, typically ranges from 1 to 10. An earthquake with an 8-magnitude is far more problematic than one with a 3-magnitude.

The index of refraction of the transparent material is approximately 1.46.

The index of refraction (n) of a transparent material is defined as the ratio of the speed of light in vacuum to the speed of light in the material. The relationship between the angles of incidence (θ₁) and refraction (θ₂) and the indices of refraction of the two media can be described by Snell's law, which states that:

n₁ sin(θ₁) = n₂ sin(θ₂)

where n₁ is the index of refraction of the first medium (in this case, air), and n₂ is the index of refraction of the second medium (the transparent material).

Given that the angle of incidence is 25 degrees and the angle of refraction is 17 degrees, we can use Snell's law to solve for n₂:

n₁ sin(θ₁) = n₂ sin(θ₂)

(1.000 sin 25°) = n₂ sin 17°

Solving for n₂, we get:

n₂ = (1.000 sin 25°) / sin 17°

n₂ ≈ 1.46

the final velocity of the hot air balloon before touching the ground is  286.16 ft/s.

the final velocity can be calculated as follows:

initial velocity of the sphere, u = 10 ft/s

Acceleration due to gravity, g = 32 ft/s²

Ground clearance, h = 1280 feet

The time it takes for the ball to hit the ground is calculated as:

\(h= ut +\frac{1}{2}gt^2\\ 1280= 10t + (0.5X 32 )t^2\\1280 = 10t +16t^2\\16t^2+ 10t-960 = 0\)

then we can solve the quadratic equation using formula method

\(t=\frac{ -b+/- \sqrt{b^2-4ac} }{2a} \\t = \frac{ -10+/- \sqrt{10^2-4(16X1280)} }{2(16)}\\t= 8.63\)

The final velocity of a hot air balloon is calculated as:

v = u + gt

v = 10 + (8.63 × 32)

v = 286.16 ft/sec

therefore, the final velocity of the hot air balloon before touching the ground is  286.16 ft/s.

If the resistance remains constant and the voltage doubles, the power will increase by a factor of 4 (option E)

The following data were obtained from the question:

P = V² / R

Resistance is constant, we have

V₁² / P₁ = V₂² / P₂

V² / P = (2V)² / P₂

V² / P = 4V² / P₂

Cross multiply

V² × P₂ = P × 4V²

Divide both side by V²

P₂ = P × 4V² / V²

P₂ = P × 4

Answer:

XXXTENTACION or Juice WRLD?

Explanation:

To determine the work done by an external agent to stretch a spring 6.50 cm from its unstretched position, we need to consider the equation for the work done on a spring.

The work done (W) on a spring is given by the equation \(W = (1/2) k x^2\), where k is the spring constant and x is the displacement of the spring from its equilibrium position. In this case, the spring is stretched 6.50 cm, which is equivalent to 0.065 m.

To find the work done, we need to know the value of the spring constant. The spring constant represents the stiffness of the spring and determines how much force is required to stretch or compress it. Once we have the spring constant value, we can substitute it along with the displacement into the work equation to calculate the work done by the external agent.

It's important to note that the work done to stretch a spring is positive, as energy is transferred to the spring. The spring stores this potential energy in the form of elastic potential energy, which can be released when the spring returns to its original position.

When a rocket ship accelerating in outer space runs out of fuel, it will no longer accelerate. This is because acceleration requires a force, and in the absence of fuel, there is no force to continue propelling the rocket forward.

According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force. Therefore, when the rocket ship runs out of fuel, it will continue to move at a constant velocity in the direction it was traveling at the moment the fuel was depleted. It will not slow down or stop unless acted upon by an external force, such as gravity or air resistance, if present.

I only know the formula which is ω = 2πf

If I hold a positive charge in my hand and there are positive charges of equal magnitude 1 mm to your north and 1 mm to your east then the direction of the force on the charge I am holding is towards the north-east direction.

Reasoning:

It is given that there is a positive charge in my hand. There are two more positive charges with the same magnitude. One is 1 mm far towards the east, and the other one is 1 mm far towards the north. It is required to find the direction of the force acting on the charge in my hand.

Let the magnitude of the charge in my hand is Q, and the magnitude of the other charges is q.

Thus the electric force applied on the charge in my hand due to each other is,

\(F=\frac{kQq}{r^2}\)

Here k is the Coulomb constant, and r is the distance between the charges.

It is also known that the force on a positive charge due to another positive charge is acted outwards.

Thus, the force on the charge due to the charge on the east is,

\(\vec{F_1}=\frac{kQq}{( 10^{-3}\text{ m})^2}\hat{i}\)

And the force on the charge due to the charge on the north is,

\(\vec{F_2}=\frac{kQq}{( 10^{-3}\text{ m})^2}\hat{j}\)

As the forces are equal in magnitude and one is perpendicular to the other, thus the net force will be acted at an angle of \(45^\circ\) from the north or from the north direction.

Thus the net force is acting in the north-east direction.

Dropping a ball of dough onto a kitchen counter, its energy store of potential energy is converted into kinetic energy as it falls. Upon impact, the kinetic energy is converted into potential, thermal, and sound energy.

When a ball of dough is dropped onto a kitchen counter, there is a change in the energy store of the dough. Initially, the dough has potential energy due to its position above the counter. As the dough is dropped, this potential energy is converted into kinetic energy, or energy of motion. As the dough falls, it gains speed and thus increases in kinetic energy.

When the dough strikes the counter, the kinetic energy is converted into a combination of potential energy and thermal energy. The dough compresses and deforms upon impact, increasing its potential energy. The compression and deformation also generates heat, which increases the thermal energy of the dough. A portion of the kinetic energy is also converted into sound energy as the dough makes contact with the counter.

The frequency of light when it reaches Earth is approximately 4.988 x 10^14 Hz.

Explanation:-

Given:

Emitted frequency of light, f = 5.000 x 10^14 Hz,

Speed of the galaxy receding from Earth, v_src = 4500 km/s.

We need to convert the speed of the galaxy from km/s to m/s:

v_src = 4500 km/s * (1000 m/km)

v_src = 4.5 x 10^6 m/s

Plugging the given values into the Doppler effect formula:

f' = (5.000 x 10^14 Hz) * (3.00 x 10^8 m/s + 0 m/s) / (3.00 x 10^8 m/s + 4.5 x 10^6 m/s)

Simplifying the expression:

f' = (5.000 x 10^14 Hz) * (3.00 x 10^8 m/s) / (3.00 x 10^8 m/s + 4.5 x 10^6 m/s)

The maximum wavelength (\lambda_{\max }) for the Sun is approximately 5.01 × 10^-7 meters.

To find the maximum wavelength (\lambda_{\max}) for the Sun, we can use Wien's Law. According to Wien's Law, the wavelength at which an object emits the maximum amount of radiation is inversely proportional to its temperature.

The temperature of the Sun can be estimated using the Stefan-Boltzmann Law, which states that the power output of a blackbody is proportional to the fourth power of its temperature. Given that the total power output of the Sun is 3.8510²⁶ W, we can use this information to find the temperature.

By rearranging the Stefan-Boltzmann Law equation, we get:

T = (P/σ)^1/4

where T is the temperature, P is the power output, and σ is the Stefan-Boltzmann constant (5.67 × 10^-8 W m^-2 K^-4).

Plugging in the values, we have:

T = (3.8510²⁶ / 5.67 × 10^-8)^1/4

Simplifying this expression, we find:

T ≈ 5778 K

Now that we have the temperature of the Sun, we can find the maximum wavelength using Wien's Law, which states:

\lambda_{\max } = \frac{b}{T}

where \lambda_{\max } is the maximum wavelength, b is Wien's displacement constant (2.8978 × 10^-3 m K), and T is the temperature.

Plugging in the values, we have:

\lambda_{\max } = \frac{2.8978 × 10^-3}{5778}

Calculating this expression, we find:

\lambda_{\max } ≈ 5.01 × 10^-7 m

Therefore, the maximum wavelength (\lambda_{\max }) for the Sun is approximately 5.01 × 10^-7 meters.

Answer: First, let's resolve the forces acting on the box along the horizontal axis:

T cos(30) - f = ma

where T is the tension force, f is the friction force, m is the mass of the box, and a is its acceleration.

We can also resolve the forces along the vertical axis:

T sin(30) - W = 0

where W is the weight of the box.

Solving for T and W:

T = 400 N

W = 1292 N

T sin(30) = (400 N) sin(30) = 200 N

W = 1292 N

Now we can substitute these values into the horizontal equation and solve for the acceleration:

T cos(30) - f = ma

(400 N) cos(30) - (45 N) = (m)a

(346.4 N) = (m)a

a = (346.4 N) / m

We can calculate the mass of the box using its weight:

W = mg

1292 N = m(9.81 m/s^2)

m = 131.8 kg

Now we can substitute the mass into the equation:

a = (346.4 N) / (131.8 kg)

a ≈ 2.63 m/s^2

Therefore, the correct answer is not listed. The acceleration of the box is approximately 2.63 m/s^2.
