Answer 2

Answer:

What I think a Satellite is...

Explanation:

A satellite may be a moon, planet or machine that circles a planet or star. For example, Earth could be a satellite since it circles the sun. Moreover, the moon may be a obsequious since it circles Soil. As a rule, the word "satellite" refers to a machine that's propelled into space and moves around Earth or another planet in space.

Utility companies charge by the kilowatt-hour. The number of kilowatt-hours used equals the number of kilowatts multiplied by the number of hours an electrical device was used. How long would it take for a 50-watt fan to use 1 kilowatt-hour of electricity? (Hint: 50 watts = 0.05 kilowatts.)

Answers

Answer:

t = 3 minutes

Explanation:

Given that,

Power of fan, P = 50 W

Energy used, E = 1 kWh

We know that,

Energy = Power/time

As, 50 watts = 0.05 kilowatts

So,

[tex]t=\dfrac{P}{E}\\\\t=\dfrac{0.05\ kW}{1\ kWh}\\\\t=0.05\ h[/tex]

or

t = 3 min

So, the required time is equal to 3 minutes.

A uniform electric field, with a magnitude of 449 N/C, is directed parallel to the positive x-axis. If the potential at x= 4.59 m is 966 V, what is the potential at x= 1.61 m?

Answers

Answer:

2.334‬ kV

Explanation:

Since the electric field strength Ecosθ = -ΔV/Δx = -(V₂ - V₁)/(x₂ - x₁)

where V₁ = potential at x₁ = 966 V, x₁ = 4.59 m, V₂ = potential at x₂ = unknown, x₂ = 1.61 m and θ = angle between E and the x - axis.

Given that E = + 449 N/C and since it is directed parallel to the positive x - axis, θ = 0°

So,

Ecosθ = -ΔV/Δx

Ecos0° = -ΔV/Δx

E = -ΔV/Δx

E = -(V₂ - V₁)/(x₂ - x₁)

making V₂ subject of the formula, we have

-E(x₂ - x₁) = V₂ - V₁

-E(x₂ - x₁) + V₁ = V₂

V₂ = V₁ - E(x₂ - x₁)

Substituting the values of the variables into the equation, we have

V₂ = V₁ - E(x₂ - x₁)

V₂ = 966 V - 449 N/C(1.61 m - 4.59 m)

V₂ = 966 V - 449 N/C(-2.98 m)

V₂ = 966 V + 1,338.02‬ Nm/C

V₂ = 966 V + 1,338.02‬ V

V₂ = ‭2,334.02‬ V

V₂ ≅ ‭2,334‬ V

V₂ = ‭2.334‬ kV

Suppose you needed to push a 1,500-N sofa up a frictionless ramp with a 30° angle. How much force would you have to apply to the sofa?Show your work below.

Answers

Answer:

1299N

Explanation:

GIven data

Weight W= 1500N

Angle Ф= 30°

The applied force up the frictionless ramp is gotten by applying the formula below

F= WcosФ

substitute

F=1500 cos 30

If a cheetah runs 352 meters in 20 seconds, what is the speed of the cheetah?

Answers

Answer:

63360 mi/h

Explanation:

How to find the speed of an object

Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown SDT value given two known values.

Time can be entered or solved for in units of second S (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm: ss). See shortcuts for time formats below.

To solve for distance use the formula for distance D = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

Therefore, the speed = 63360 miles per hour

= 63360 mi/h

Pedro y Juan van a la escuela en bicicleta. Pedro vive a 5 km de distancia al este de la escuela, y Juan al oeste es decir -4 km. Si ambos hicieron un tiempo de 0.25 horas. Cuál es la velocidad de cada uno?

Answers

Answer:

Lo primero que hay que recordar es la relación:

Velocidad = Distancia/tiempo.

Para el caso de Pedro, el vive a 5km de la escuela (es decir, para llegar a la escuela, el debe recorrer -5km, entonces la distancia es -5km), y recorre esa distancia en 0.25 horas, entonces su velocidad es:

Velocidad = -5km/0.25hr = -20km/h

Esto significa que Pedro se mueve con una velocidad de -20km/h, lo que significa que se mueve hacia el oeste con un módulo de 20km/h

Para el caso de Juan, el vive a -4km de la escuela, entonces el tendrá que recorrer 4km para llegar a la escuela, y los recorre en 0.25 horas, entonces su velocidad sera:

Velocidad = 4km/0.25h = 16 km/h

Lo que significa que Juan tiene una velocidad de 16km/h hacia el este.

heena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation? v = one-third pi 24 squared (12). v = one-third p 12 squared (24). v = four-thirds pi 24 cubed. v = four-thirds pi 12 cubed.

Answers

Answer:

v = four-thirds pi 12 cubed.

Explanation:

A ball has a spherical shape. The volume of a spherical shape can be calculated using the following formula:

[tex]V = \frac{4}{3} \pi r^3[/tex]

where,

V = Volume of Ball = ?

d = diameter of the ball = length across the ball = 24 cm

r = radius of ball = d/2 = 24 cm/2 = 12 cm

Therefore,

[tex]V = \frac{4}{3}\pi (12)^3[/tex]

A microphone is attached to a spring that is suspended from the ceiling, as the drawing indicates. Directly below on the floor is a stationary 375-Hz source of sound. The microphone vibrates up and down in simple harmonic motion with a period of 1.80 s. The difference between the maximum and minimum sound frequencies detected by the microphone is 2.75 Hz. Ignoring any reflections of sound in the room and using 343 m/s for the speed of sound, determine the amplitude (in m) of the simple harmonic motion.

Answers

Answer:

[tex]0.361\ \text{m}[/tex]

Explanation:

[tex]f_s[/tex] = Frequency of source = 375 Hz

[tex]\Delta f[/tex] = Difference between the maximum and minimum sound frequencies = 2.75 Hz

v = Speed of sound in air = 343 m/s

T = Time period = 1.8 s

[tex]v_m[/tex] = Maximum speed of the microphone

We have the relation

[tex]\Delta f=2f_s\dfrac{v_m}{v}\\\Rightarrow v_m=\dfrac{\Delta fv}{2f_s}\\\Rightarrow v_m=\dfrac{2.75\times 343}{2\times 375}\\\Rightarrow v_m=1.26\ \text{m/s}[/tex]

Amplitude is given by

[tex]A=\dfrac{v_mT}{2\pi}\\\Rightarrow A=\dfrac{1.26\times 1.8}{2\pi}\\\Rightarrow A=0.361\ \text{m}[/tex]

The amplitude of the simple harmonic motion is [tex]0.361\ \text{m}[/tex].

v = 327.75ms²

A produces a sound at a frequency of 17,250 Hz and wavelength of 0.079 m then the speed of sound will be equal to 327.75 m/s².

What is Wavelength?

The distance between two identical locations (adjacent crests) in successive cycles is known as the wavelength, and it is used to describe waveform signals that are transmitted over wires or into space. Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimeters (mm). The wavelength is more frequently described in nanometers (nm), which are units of 10⁻⁹ m, or angstroms, which are units of 10⁻¹⁰ m, for infrared (IR), visible light (UV), and gamma radiation.

As per the given information in the question,

Frequency, f = 17,250 Hz

The wavelength λ = 0.019 m

Then the speed of the sound (v) will be,

v = f × λ

v = 17250 × 0.019

v = 327.75 m/s²

A 200kg bumper car moving 3 m/s collides head on with a 392kg bumper car moving 6m/s. After impact, the larger car continues traveling in the same direction with a velocity of 1.6 m/s . Determine the speed of the other car.

Answers

Answer:

the final speed of the smaller car is 5.624 m/s

Explanation:

Given;

mass of the small car, m₁ = 200 kg

initial velocity of the small car, u₁ = 3 m/s

mass of the larger car, m₂ = 392 kg

initial velocity of the larger car, u₂ = 6 m/s

final velocity of the larger car, v₂ = 1.6 m/s

let the direction of the larger car be positive

let the direction of the smaller car be negative

Apply the principle of conservation of linear momentum to determine the final speed of the smaller car.

m₁u₁ + m₂u₂ = m₁v₁  +  m₂v₂

200(-3)  +  392(6)  = 200v₁   +  392 x 1.6

-600 + 2352  = 200v₁    +  627.2

1752   =  200v₁     +   627.2

1752  -  627.2     =  200v₁

1124.8  = 200v₁

v₁  =  1124.8/200

v₁ = 5.624 m/s

Therefore, the final speed of the smaller car is 5.624 m/s
