what does the number 2.001 represent in the following: t(58) = 2.001, p < .05?

Answer:

The motorcyclist is 55 miles east of the small town.

Explanation:

Motion With Constant Acceleration

It's a type of motion where the velocity of an object changes uniformly in time.

The equation that rules the change of velocities is:

\(v_f=v_o+at\qquad\qquad [1]\)

Where:

a   = acceleration

vo = initial speed

vf  = final speed

t    = time

The distance traveled by the object is given by:

\(\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad\qquad [2]\)

Using the equation [1] we can solve for a:

\(\displaystyle a=\frac{v_f-v_o}{t}\)

Solving [1] for t and substituting into [2] we get the following equation:

\(V_f^2=V_o^2+2aX\)

The motorcyclist has an acceleration of a=4\ m/s^2 and an initial distance of 5 m where he travels at vo=15 m/s.  It's required to calculate the distance when the speed is vf=25 m/s.

Solving the last equation for X:

\(\displaystyle X=\frac{V_f^2-V_o^2}{2a}\)

Substituting:

\(\displaystyle X=\frac{25^2-15^2}{2*4}\)

\(\displaystyle X=\frac{625-225}{8}\)

X = 50 m

Adding the initial distance:

The motorcyclist is 55 miles east of the small town.

The force applied to stretched the spring 3.2 m, given that the spring has a spring constant of 0.52 N/m is 1.664 N

Hooke's law gives a relationship betwee force, extension and spring constant according to the following formula:

Force (F) = Spring constant (K) × extension (e)

F = Ke

With the above formula, we can determine the force applied to the spring as illustrated below:

Force (F) = Spring constant (K) × extension (e)

Force applied (F) = 0.52 × 3.2

Force applied (F) = 1.664 N

Thus, we can conclude from the above calculation that the force is 1.664 N

Explanation:

700N right

to get the net force

you gotta let one direction be the negative ( the smaller force)

so the total force towards the left is 100N ( 60 + 40= 100)

which is smaller than the right force which is 800 N so you let 100 N be negative

so without even calculating , you can know that it will be moving towards the right because right force > left force

your add both forces ( remember 100 N is negative)

so 800N + ( - 100N)

= 700N

towards the right

Owing to the fact that planets orbits the sun at different speeds, Mars and Jupiter does appear to move backwards for some period of time. The geocentric model fails to explain this.

The geocentric model of the solar system is the approach that held the earth rather than the sun as the center of the solar system. The geocentric model was favored by most of the early astronomers.

The beat frequency between Middle C (262 Hz) and C# (277 Hz) played together is 15 Hz.

When two tones with slightly different frequencies are played together, they create an interference pattern known as beats. The beat frequency is the difference between the frequencies of the two tones. In this case, the frequency of Middle C is 262 Hz, and the frequency of C# is 277 Hz.

To find the beat frequency, we subtract the lower frequency from the higher frequency: 277 Hz - 262 Hz = 15 Hz.

When Middle C and C# are played simultaneously, their waveforms interfere with each other. The constructive and destructive interference of the sound waves results in a pattern of alternating loudness known as beats. The beat frequency is the rate at which these loudness variations occur.

In this case, the difference in frequency between Middle C and C# is 15 Hz. This means that there will be 15 beats per second when these two notes are played together. The beat frequency adds an interesting texture to the sound and can be perceived as a pulsating or throbbing sensation.

To transfer a satellite from a circular orbit to an elliptical orbit, the rocket motor must do work equal to the change in the satellite's potential energy. This is because the potential energy of the satellite is directly related to its distance from the center of the planet.

As the satellite moves from a circular orbit to an elliptical orbit, its distance from the center of the planet changes, which results in a change in its potential energy.

The amount of work required to change the potential energy of the satellite can be calculated using the following formula: Work = ∆PE = GMm(1/a - 1/b), where G is the gravitational constant, M is the mass of the planet, m is the mass of the satellite, a is the initial radius of the circular orbit, and b is the maximum radius of the elliptical orbit.

Therefore, the rocket motor must do work equal to GMm(1/a - 1/b) to transfer the satellite from the circular orbit to the elliptical orbit.

1.87 x \(10^8 N/C\) is the magnitude of the electric field on the axis of the disk at a distance of 15.2 cm from the disk's center.

To calculate the electric field on the axis of the disk at a distance of 15.2 cm from the center,

we can use the formula for the electric field due to a uniformly charged circular disk:

E = (σ/2ε₀) * [1 - (z/√(z² + R²))]

Where,

σ is the surface charge density of the disk (charge per unit area),

ε₀ is the electric constant (also known as the permittivity of free space),

z is the distance from the center of the disk to the point where we want to calculate the electric field, and

R is the radius of the disk.

First, we need to find the surface charge density σ.

We are given that the charge on the disk is 204 nC, and the disk has a top surface area of:

A = πR² = π(0.131 m)² = 0.0539 m²

Therefore, the surface charge density is:

σ = Q/A = 204 nC / 0.0539 m² = 3785.5 nC/m²

Next, we can plug in the values for σ, z, and R into the electric field formula:

E = (σ/2ε₀) * [1 - (z/√(z² + R²))]

E = (3785.5 nC/m² / (2 * 8.85 × 10^-12 F/m)) * [1 - (0.152 m / √(0.152 m)² + (0.131 m)²)]

E = 187381024.7 N/C

Therefore, the magnitude of the electric field on the axis of the disk at a distance of 15.2 cm from the center is 1.87 × \(10^8\) N/C.

The frequency of the wave in seawater will be "2.68 Hz".

Frequency is the number of waves passes in a unit of time.

The following formula can be used to determine the relationship between the wave's speed, wavelength, and frequency:

\(v = f \lambda\\\\ \lambda = \dfrac{v}{f}\)

The wavelength of the wave is a constant property:

\(\dfrac{v_1}{f_1} = \dfrac{v_2}{f_2}\)

Where, v₁ = speed of the wave in the rock = 3950 m/s

v₂ = speed of the wave in the seawater = 1500 m/s

λ = wavelength = 560 m

f₁ = frequency of the wave in the rock =

f₂ = frequency of the wave in the seawater = ?

Put the numbers in the formula:

\(\dfrac{3950}{7.05} = \dfrac{1500}{f_2}\\\\f_2 = \frac{(7.05)(1500)}{3950} = 2.68 Hz\)

The mechanical advantage (MA) of a simple machine is defined as the ratio of the output force to the input force.

So, to find the MA of a simple machine that requires a 50 N input to produce a 240 N output, we can use the formula:

MA = output force / input force

Given that the input force is 50 N and the output force is 240 N, we can plug these values into the formula:

MA = 240 N / 50 N

MA = 4.8

Answer:

F = -8820 N

Explanation:

Given that,

The weight of a car, W = 19600 N

Initial speed of the car, u = 30 m/s

It is brought to rest, final velocity, v = 0

Distance, d = 100 m

We need to find the average friction force acting on it.

Firstly we find the acceleration of the car using third equation of motion. Let it is a.

\(v^2-u^2=2as\\\\a=\dfrac{v^2-u^2}{2d}\\\\a=\dfrac{(0)^2-(30)^2}{2\times 100}\\\\=-4.5\ m/s^2\)

Average frictional force,

F = ma

m is mass, \(m=\dfrac{W}{g}=\dfrac{19600\ N}{10\ m/s^2}=1960\ kg\)

F = 1960 kg × -4.5 m/s²

= -8820 N

So, the average friction force acting on it is 8820 N.
