The horizontal we need to use the formula for work done, which is Work = Force x Distance x cos theta in this case, the distance is not given, but we know that the block is moving at a constant speed of 3 meters per second. Distance = Speed x Time. Distance = 3 m/s x 60 s = 180 m

The time given is 1 minute, which is 60 seconds, Distance = 3 m/s x 60 s = 180 m Now we can calculate the work done by the force Of Work = F x Distance x cos theta Since the force is horizontal and the displacement is also horizontal, the angle between them is 0 degrees and cos0 = 1. Work = F x Distance We need to find the value of F. Since the block is moving at a constant speed, the force applied by F must be equal and opposite to the frictional force F = frictional force = 10 N Now we can substitute the values Work = 10 N x 180 m = 1800 J the answer is (E) 1800 J.

To achieve a frequency resolution of 0.1Hz with data ranging from 0 to 500Hz, you would need to use a block size of at least 5,000 samples.

This is because the formula for frequency resolution is given by the sampling rate divided by the block size, so a sampling rate of 10,000Hz (assuming a Nyquist frequency of 5,000Hz) divided by a block size of 5,000 samples would give a frequency resolution of 0.1Hz.
Hi! To achieve a frequency resolution of 0.1 Hz in a range of 0 to 500 Hz, you can use the formula:

Minimum block size = Sample rate / Frequency resolution

In this case, the sample rate is 500 Hz and the desired frequency resolution is 0.1 Hz. Plugging these values into the formula:

Minimum block size = 500 Hz / 0.1 Hz = 5000

Therefore, the smallest block size you must use is 5000 samples.

To calculate the frequency of the sound heard by the person, we need to consider the Doppler effect, which describes the change in frequency due to the relative motion between the source of the sound and the observer.

The formula for the observed frequency due to the Doppler effect is given by:

f_observed = f_source * (v_sound + v_observer) / (v_sound + v_source)

where:

f_observed is the observed frequency,

f_source is the source frequency,

v_sound is the speed of sound in air, and

v_observer and v_source are the velocities of the observer and the source, respectively.

Given:

Source frequency (f_source) = 1.44 × 10^3 Hz

Speed of sound in air (v_sound) = 343 m/s

Velocity of the siren (v_source) = 15 m/s

Velocity of the observer (v_observer) = 0 m/s (since the observer is at rest)

(a) Frequency of the sound directly from the siren:

For this scenario, the observer and the siren are moving away from each other. Substituting the given values into the Doppler effect formula:

f_observed = 1.44 × 10^3 * (343 + 0) / (343 + 15)

(b) Frequency of the sound reflected from the cliff:

In this case, the sound waves are reflected by the cliff, resulting in a change in direction. The relative motion between the observer and the reflected sound is the sum of their individual velocities. Thus, we consider the observer's velocity as -15 m/s (since it's moving towards the observer).

f_observed = 1.44 × 10^3 * (343 + 0) / (343 - 15)

By performing the calculations, we can determine the frequencies of the sound heard by the person directly from the siren and reflected from the cliff.

The dump truck has 7.2 times more kinetic energy than the car.

In order to determine how many times more kinetic energy a dump truck has than a car, we need to know the masses and velocities of both vehicles and apply the kinetic energy formula. The formula for kinetic energy is KE = 1/2mv² where KE is kinetic energy, m is the mass, and v is the velocity. Let's assume the mass of the dump truck to be 20,000 kg and the velocity to be 30 m/s. Also, let's assume the mass of the car to be 1,000 kg and the velocity to be 50m/s. Kinetic energy of the dump truck is:

KE of dump truck = 1/2 x 20,000 kg x (30 m/s)² = 9,000,000J

Kinetic energy of the car is: KE of car = 1/2 x 1,000 kg x (50 m/s)² = 1,250,000J

Therefore, the dump truck has 7.2 times more kinetic energy than the car. This is calculated by dividing the kinetic energy of the dump truck by the kinetic energy of the car.7.2 = 9,000,000 J / 1,250,000 J Thus, the dump truck has 7.2 times more kinetic energy than the car.

Digital filters are important in digital signal processing. FIR and IIR filters are two types of digital filters. The main difference between FIR and IIR filters is that FIR filters are known as non-recursive filters, while IIR filters are recursive filters. In this answer, we will explore more about the differences between FIR and IIR filters.

FIR Filters FIR stands for finite impulse response. FIR filters are also called non-recursive filters. In an FIR filter, the output depends only on the current input and the previous inputs. FIR filters are also known as moving average filters. FIR filters have a linear phase response, which makes them useful in audio and image processing. FIR filters have more stable responses compared to IIR filters, which means they are more predictable.

IIR filters are more efficient than FIR filters because they use feedback loops. IIR filters have nonlinear phase responses, which make them useful in signal processing and control systems. IIR filters are less stable than FIR filters, which means they are less predictable.

Answer:

h = 35857 km

Explanation:

A geosynchronous orbit can be defined as circular orbit which lies on the Earth's equatorial plane and follows the direction of the Earth's rotation in a period that's equal to the Earth's rotational period and thereby appearing motionless, at a fixed position in the sky relative to the ground observers.

We are given;

Radius of earth(R) = 6.37 x 10^(6) m

Mass of earth (Me) = 5.97 x 10^(24) kg

Gravitational constant = 6.67 × 10^(-11) m³/kg.s²

The earth has a rotational period of 24 hours per day. This gives in seconds

T = 24 × 60 × 60

T = 86400 s

Let's make the height of the orbit from Earth's surface to be h

Also, let ω be the uniform angular velocity in rad/s with which the satellite rotates in the geosynchronous orbit

Now, equating the centripetal force with the gravitational force gives us;

mω²(R + h) = G•Me•m/(R + h)²

m will cancel out. Also ω can be written as 2π/T

Thus,we now have;

(R + h) = ∛(G•Me•T²/(4π²))

Plugging in the relevant values, we have;

(R + h) = ∛(6.67 × 10^(-11) × 5.97 x 10^(24) × 86400²/(4π²))

(R + h) = 42227 Km

Since R = 6.37 x 10^(6)m = 6370 km

Thus;. h = 42227 - 6370 = 35857 km

The final velocity of the airplane is 75.1 m/s.

Velocity can be defined as the measurement of rate and direction of motion.

The velocity of a moving object changes with time. Thus, a moving object will have an initial velocity as well as a final velocity.

The formula for final velocity, V is given by the formula below:

v = √(u² + 2as)

where

The values are as follows:

u = 25.88 m/s

a = 4.21 m/s²

s = 590.39 m

Substituting the values

v = √{(25.88)² + 2 * 4.21 * 590.39)}

v = 75.1 m/s

Therefore, the final velocity, v is 75.1 m/s

For this exercise let's use the relationship between work and the change in kinetic energy

         W = ΔK

the expression for work is

         W = - τ Δθ

where the negative sign indicates that the torque is in the opposite direction to rotation

kinetic energy

           K = ½ I w²

we substitute

           - τ Δθ = 0 - ½ I w²

           θ = \(\frac{1}{2} \ \frac{I w^2}{\tau}\)

if we approach the rotor to a cylinder with an axis of rotation through its center

          I = ½ m r²

we substitute

          θ = ½ (½ m r²)   \(\frac{w^2}{\tau}\)

How the measurements are in the English system, the weight
