Two in-phase sources of waves are separated by a distance of 3.50 m. These sources produce identical waves that have a wavelength of 5.96 m. On the line between them, there are two places at which the same type of interference occurs (a) Is it constructive or destructive interference, and (b) where are the places located?
Answer:
(a) It is a destructive interference
(b) The places at which destructive interference occur on the line between the two in-phase sources, are 1.07798 m before and after the two sources
Explanation:
(a) The given parameters are;
The distance between the two in-phase sources, d = 3.50 m
The type of waves produced by the two sources = identical waves
The wavelength of the waves produced by the two sources, λ = 5.96 m
For constructive interference, we have;
d·sin(θ) = m·λ
Where, m = 0, 1, -1, 2, -2, ...
For destructive interference, we have;
[tex]d \cdot sin(\theta) = \left(m + \dfrac{1}{2} \right) \cdot \lambda[/tex]
d·sin(θ) = Δl =
Where, m = 0, 1, -1, 2, -2, ...
Therefore, given that λ > d, for constructive interference
sin(θ) = m·λ/d > 1 for m > 0 which is invalid as the maximum value for sin(θ) = 1
Therefore, the possible interference is destructive interference
(b) For destructive interference, when m = 0, we have;
[tex]3.5 \times sin(\theta) = \left(0 + \dfrac{1}{2} \right) \times 5.96[/tex]
∴ sin(θ) = (5.96/2)/3.5
θ = arcsin((5.96/2)/3.5)
By trigonometry, we have;
tan(θ) = (d/2)/l
Where
l = The location along the line
∴ l = (d/2)/(tan(θ))
By substitution, we have;
l = (3.5/2)/(tan(arcsin((5.96/2)/3.5))) = 1.07798
Therefore, the two locations along the line where there is a destructive are 1.07798 m along the line before and after the two in-phase sources.

En un tiempo de 60 s (segundos), una masa de 0,0014 kg, cambia su velocidad de 25 m/s a 60 m/s. Determine qué fuerza actúa sobre el mismo.
Answer:
Fuerza = 0.0082 Newton
Explanation:
Dados los siguientes datos;
Velocidad inicial, u = 25 m/s
Velocidad final, v = 60 m/s
Tiempo, t = 60 segundos
Masa = 0,0014 kg
Para encontrar la fuerza que actúa sobre el objeto;
En primer lugar, determinaríamos la aceleración del objeto.
Aceleración = (v - u)/t
Aceleración = (60 - 25)/60
Aceleración = 35/60
Aceleración = 5.83 m/s²
A continuación, encontramos la fuerza;
Fuerza = masa * aceleración
Fuerza = 0.0014 * 5.83
Fuerza = 0.0082 Newton

What is velocity ratio? It is impossible to get a perfect machine in practical life, why?
Explanation:
VELOCITY RATIO :- The ratio of a distance through which any part of a machine moves to that which the driving part moves during the same time.if you push a small act with 7,000 N force and push a heavy truck with the same force, which one will have a greater acceleration?
Answer:
the small one will have greater acceleration
Explanation:
force and mass are inversely proportional. force and acceleration are directly proportional. which means greater mass have smaller acceleration and smaller mass has greater acceleration. this is due to newtons second law of motion.
The small object will have greater acceleration as compared to a heavy truck if we push with the same amount of force, i.e., 7000 N.
What is acceleration?Acceleration is proportional to change in velocity.
When there will be a change in velocity with time, that is called acceleration.
[tex]\vec{a}[/tex]=[tex]\vec{dv}/dt[/tex] where,
[tex]\vec{a}[/tex] is the acceleration,
[tex]\vec{dv}[/tex] is the change in velocity and,
dt is change in time.
It is a vector quantity.
SI unit of acceleration is [tex]m/s^{2}[/tex].
There are several types of acceleration :
Uniform acceleration Non-Uniform accelerationInstantaneous acceleration.As we know that acceleration depends on the change in velocity and velocity of a body depends on the mass of the body. So if the body has less mass it must have a higher velocity and if it has a higher velocity than it has greater acceleration.
Hence, the small object/body has greater acceleration as compared to a heavy truck.

A day on a distant planet observed orbiting a nearby star is 21.5 hr. Also, a year on the planet lasts 69.3 Earth days. In other words, for the purposes of unit conversion, there are 24 hr in a day, 60 min in an hour, and 60 s in a minute, as it would for astronomers on Earth observing the planet. Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth. what is the speed of rotation? Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth. what is the speed of orbit?
Answer:
Part A
The angular speed of rotation of the plane is 8.11781 × 10⁻⁵ rad/s
Part B
The angular speed of orbit of the planet is 1.04938 × 10⁻⁶ rad/s
Explanation:
The parameters of the planet are;
The duration of a day on the distant planet = 21.5 hr.
The duration of a year on the distant planet = 69.3 Earth days
Part A
The duration of a day = The time to make one complete revolution of 2·π radians

A runner slows down after completing works her deceleration is 0.25m/s after 5 sec she is traveling at 4m/s determine her initial velocity
Answer:
vi = 5.25 m/s
Explanation:
We can determine the initial velocity of the runner by using the first equation of motion, as follows:
[tex]v_f = v_i + at\\[/tex]
where,
vf = final speed of the runner = 4 m/s
vi = initial speed of the runner = ?
a = deceleration of the runner = - 0.25 m/s²
t = time taken = 5 s
Therefore,
[tex]4\ m/s = v_i + (-0.25\ m/s^2)(5\ s)\\v_i = 4\ m/s + 1.25\ m/s\\[/tex]
vi = 5.25 m/s
Question:
To increase the energy efficiency of their home, a Colorado family
installed a solar panel on its roof. They want to add another solar panel to
increase their ability to store energy for the winter. What happens to the
current (1) when they add another solar panel (V)? *
Answer: When they add another solar panel, there will be INCREASE in current.
Explanation:
The movement of electric charges through a conductor is known as CURRENT (I) and is measured in ampere(A). Voltage is defined as the potential energy that moved charged particles. While resistance is the opposition to the flow of electric charges.
The increase in current abides by the rules of ohm's law which states that the electric current in a given metallic conductor is directly proportional to the potential difference (Voltage) applied between its ends, provided that the temperature of the conductor and other physical factors remain constant. This relationship simply means that increase in voltage will lead to increase in current in a circuit.This can be represented by an equation below:
V= IR
Where V = Voltage
I = Current
R = Resistance
Since increase in voltage lead to increase in current as seen in Ohm's law, therefore the addition of extra solar panels ( voltage) will lead to increase in current out put during winter.
Suppose that the ultrasound source placed on the mother's abdomen produces sound at a frequency 2 MHz (a megahertz is 10^610 6 Hz). Sound travels through tissue at roughly the same speed as in water (v\approx 1500v≈1500m/s). Find the maximum change in frequency between the sound that is emitted by the device and the sound that is observed at the wall of the baby's heart. Treat the heart wall as a moving observer. Hint: you will need to use your answer from part (a). Give your answer as a positive number in Hz.
Answer:
the maximum frequency observed is 2.0044 10⁶ Hz
Explanation:
This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is
f ’= [tex]f_o \ ( \frac{v \pm v_o}{v} )[/tex]
the + sign is used when the observer approaches the source
typical speeds of a baby's heart stop are around 200 m / min
let's reduce to SI units
v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s
let's calculate
f ’= 2 10⁶ ([tex]\frac{1500 \ \pm 3.33}{1500}[/tex])
f ’= 2.0044 10⁶ Hz
f ’= 1,9956 10⁶ Hz
therefore the maximum frequency observed is 2.0044 10⁶ Hz
