PLEASE HELP WILL GIVE BRAINLIEST!3. Given a bronze wire of length 2.5 m and cross sectional area 6.5 x 10-⁷ m². What is the elongation of the wire if it is stretched under a force of 10³ N? Given: Young modulus of bronze is 2.0 x 10-¹¹N/m².
Answer:
The elongation of the wire is approximately 4.81 x 10-³ m.
Explanation:
To find the elongation of the wire, we can use the formula:
Elongation = (Force * Length) / (Young Modulus * Cross Sectional Area)
Plugging in the given values, we have:
Elongation = (10³ N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)
We can simplify this to:
Elongation = (2500 N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)
Which simplifies to:
Elongation = (625 x 10-⁸ m³) / (1.3 x 10-¹¹ m³)
Simplifying further, we have:
Elongation = 4.81 x 10-³ m
Therefore, the elongation of the wire is approximately 4.81 x 10-³ m.
It's important to note that this is an approximate value, as the actual elongation may depend on various factors such as the temperature and the specific properties of the wire.

what would be the distance between fringes (in cm) if the entire apparatus were submersed in water, whose index of refraction is 1.333?
The distance between fringes for 694nm is 3.267 cm and for apparatus submersed in water with index of refraction of 1.333 is 2.45cm.
In the Young’s Double Slit Experiment, the distance between adjacent fringes is Δy = xλ/d, assuming the slit separation d is large compared with λ.
The equation for the distance between fringes is given by:
Δy = xλ/d where x is the location of screen and d is slit separation. λ is the wavelength.
According to the given information,
x = 4m
d = 0.0850mm or 0.085 x 10^-3m
λ = 694 nm or 694 x 10^-9 m
Hence, using the equation, the distance between fringes is:
Δy = 4 * 694 x 10^-9 /0.085 x 10^-3 = 0.032658 m = 32.66mm = 3.267 cm
When submerged in water, wavelength in water is given by:
wavelength in water = wave length / refractive index
The refractive index of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index of water is 1.333.
wavelength in water = 694/1.333 = 520.63 nm
Hence, the new distance between fringes is
Δy = 4 * 520.63 x 10^-9 /0.085 x 10^-3 = 0.0245 m = 24.5mm = 2.45 cm
Note: The question is incomplete. The complete question probably is: Using the equation for the distance between fringes, Δy = xλ/d , complete the following. (a) Calculate the distance (in cm) between fringes for 694 nm light falling on double slits separated by 0.0850 mm, located 4.00 m from a screen. cm (b) What would be the distance between fringes (in cm) if the entire apparatus were submerged in water, whose index of refraction is 1.333? cm

It fall during the next second of time is 3hrs.
When something is released from rest and falls?Gravitational potential energy is transformed into kinetic energy as the object is propelled out of rest and falls to Earth. Since the object is released closer to the Earth's surface, the force of gravity's acceleration is constant.
Knowing this
u = 0 m/s.
velocity after t = 1s
v = u+gt
v = 0 + 9.81 x 1s
v = 9.81 m/s
area covered in the first second
area covered in the first second = ut + 0.5 x g x t²
area covered in the first second =0 + 0.5x 9.81 x 1 = 4.90m
Let 4.90 be h
We will now use the distance traveled in the second second.
so that velocity after t = 1s
velocity after t is 1s = 1 x t+ 0.5 x g x t²
velocity after t is 1s = 9.81 x 1 + 0.5 x 9.81 x 1 = 3 x 4.90

A group of students prepare for a robotic competition and build a robot that can launch large spheres of mass M in the horizontal direction with variable speed and from a variable vertical position and a fixed horizontal position x=0.
The robot is calibrated by adjusting the speed at which the sphere is launched and the height of the robot’s sphere launcher. Depending on where the spheres land on the ground, students earn points based on the accuracy of the robot. The robot is calibrated so that when the spheres are launched from a vertical position y=H and speed v0, they consistently land on the ground on a target that is at a position x=D. Positive directions for vector quantities are indicated in the figure.
When the students arrive at the competition, it is determined that the height of the sphere launcher can no longer be adjusted due to a mechanical malfunction. Therefore, the spheres must be launched at a vertical position of y=H2. However, the spheres may be launched at speed v0 or 2v0.
Question: In a clear response that may also contain diagrams and/or equations, describe which speed, v0 or 2v0, the students should launch the sphere at so that they earn the maximum number of points in the competition.
Free fall motion is motion in which the only force acting on the body is gravity.
What is free fall motion?A free-falling object is one that moves only due to the effect of gravity, and its motion is defined by Newton's second law of motion. We can use algebra to calculate the acceleration of a free-falling particle.
The student should launch the sphere at 2v₀, for the sphere will land at approximately 1.41D, which is in the 3 point zone
The given parameter are;
The distance covered by the sphere when launched at height, H = D
The velocity with which the ball reaches D = v₀
The current available height of launcher= H/2
The available velocities = v₀, and 2v₀
Now,
From H = ut + (1/2)gt², where, initial velocity of the vertical motion of the ball, u = 0
we know;
H = (1/2)gt²
Therefore, the time it takes the ball to drop from H, t = √(2H/g)
The distance, D = v₀ × √(2H/g)
When the height is H/2, we get;
t = √(2H/(2g)) = √(H/g)
Thus, the distance covered, D₁ = v₀ × √(H/g)
Therefore, D = (√2) × v₀ × √(H/g) = (√(2))D₁
Now, D₁ = D/(√2) ≈ 0.71D
D₁ ≈ 0.71D
At speed 2v₀, we have;
D₂ = 2v₀ × √(H/g) = √2 × v2 × v₀ × √(H/g) = √2 × v₀ × √(2H/g) = √2D₁ ≈ 1.41D
D₂ ≈ 1.41D
The 2 point zone = D/2 < x < D = 0.5D < x < D (Position D₁ ≈ 0.71D is located here)
The 3 Point Zone = D < x < 3D/2 = D < x < 1.5D (Position D₂ ≈ 1.41D is located here)
Given that at D₂, the ball lands in the 3 Point Zone, the student should launch the sphere at the speed, 2v₀, so that the ball will land at D₂ ≈ 1.41D, which is in the 3 Point Zone

It is possible to think about angular frequency (ω) as a way to measure angular displacement with respect to time. The equation is (K= ω/m)
Additionally known as radial or circular frequency. It can sometimes be measured in radians per second and sometimes in degrees per second.Angle frequency can be thought of as the rate at which the phase of a sinusoidal waveform changes. It can gauge how quickly the argument changes in relation to the sine function.ω=km
We are aware that k is unchanging.
Then, we can change the formula's k subject to (K= ω/m).

A 2 kg bird falls from a 15 m high tree. How fast is the bird falling right before it hits the ground?
a car with the windows rolled down is traveling north on a road at a speed of 23.0 m/s. a police car, traveling south at a speed of 38.0 m/s, approaches with its siren producing sound at a frequency of 2400 hz. (enter your answers in hz. assume that the speed of sound in air is 343 m/s.) (a) what frequency does the driver of the car observe as the police car approaches? (enter your answer to the nearest integer.) hz (b) what frequency does the driver of the car detect after the police car passes her? hz (c) repeat parts (a) and (b) for the case when the police car is traveling northbound. while police car overtakes hz after police car passes hz
a) The frequency that the driver of the car observes as the police car approaches is calculated by using the Doppler effect.
The frequency of the sound wave is increased as the source of the sound (the police car) approaches the observer (the driver of the car). The frequency observed by the driver of the car is given by:
f_observed = f_source * (v_source + v_observer) / (v_source - v_observer)
Substituting the given values, we get:
f_observed = 2400 * (38 + 23) / (38 - 23) = 4860 Hz (to the nearest integer).
b) The frequency of the sound wave is decreased as the source of the sound (the police car) moves away from the observer (the driver of the car). The frequency observed by the driver of the car is given by:
f_observed = f_source * (v_source - v_observer) / (v_source + v_observer)
Substituting the given values, we get:
f_observed = 2400 * (38 - 23) / (38 + 23) = 1380 Hz (to the nearest integer).
c)The frequency of the sound wave is decreased as the source of the sound (the police car) approaches the observer (the driver of the car). The frequency observed by the driver of the car is given by:
f_observed = f_source * (v_source - v_observer) / (v_source + v_observer)
Substituting the given values, we get:
f_observed = 2400 * (38 - 23) / (38 + 23) = 1380 Hz (to the nearest integer).
