A. 2.3 m
B. 0.43 m
C. 0.043 m
D. 23.5 m
Answers
Answer:
Option D. 23.5 m
Explanation:
From the question given above, the following data were obtained:
Frequency = 200 Hz
Speed of sound in brass = 4700 m/s
Wavelength of sound in brass =?
We can obtain the wavelength of the sound in the brass by using the following formula as illustrated below:
Wave speed = wavelength × frequency
4700 = wavelength × 200
Divide both side by 200
Wavelength = 4700 / 200
Wavelength = 23.5 m
Thus, the wavelength of the sound in the brass is 23.5 m

Answers
Answer:
empty space
Explanation:
Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.
Hence, it can be concluded that Most of our Solar system is composed of "Empty Spaces."

A plastic ball is tied to 1 end of a long string and is swung in a horizontal circle. If it takes to complete 1 circle, what is the acceleration of the ball
Answers
Explanation:
Assuming the ball is swung with a constant velocity V and radius of circle R. Therefore, The tangential acceleration of the ball would be zero.
Considering the centripetal acceleration to be a_c . we get,
[tex]a_c= \frac{V^2}{R}[/tex]

The orange-spotted filefish lives in coral reefs. Warming ocean temperatures have caused coral reef destruction, causing the filefish population to rapidly decline. (2 causes) Habitat Loss Habitat Loss Invasive Species Invasive Species Pollution Pollution Population Growth Population Growth Climate Change Climate Change Overharvesting Overharvesting
Answers
Answer:
Pollution
Climate change
Explanation:
The destruction of the coral reef can be attributed to pollution and climate change.
The pollution of the atmosphere by greenhouse gases such as carbon dioxide causes the average temperature of the planet to increase, a phenomenon that is referred to as global warming. Global warming also causes an increase in the temperature of sea waters which can lead to the death of microscopic algae, causing coral bleaching.
An increase in the concentration of carbon dioxide in the atmosphere also causes ocean acidification which, in turn, reduces the availability of materials required to form the calcium carbonate of the coral reef. In extreme cases, acidification of the ocean can cause the dissolution of the coral skeletons.
Lina holownicza wytrzymuje działanie siły o wartości co najwyżej 1400 N (większa siła powoduje rozerwanie liny). Oblicz maksymalne przyspieszenie, jakie może osiągnąć samochód o masie 2000 kg holowany na takiej linie po poziomej jezdni, jeżeli wiadomo, że łączna wartość sił oporu ruchu tego samochodu w czasie holowania wynosi 400 N.
Answers
Odpowiedź:
0,5 m / s²
Wyjaśnienie:
Jeśli się uwzględni:
Masa samochodu (m) = 2000 kg
Wartość siły oporu podczas holowania = 400N
Lina o maksymalnej sile może wytrzymać = 1400N
Maksymalne przyspieszenie = siła / masa samochodu
Siła = maksymalna siła - siła oporu
Siła = 1400 N - 400 N = 1000 N.
Stąd maksymalne przyspieszenie;
1000 N / 2000 kg
= 0,5 m / s²

A 75 kg ball carrier is running to the right at 6.5 m/s. An 80 kg defender is chasing the ball carrier running at 7.0 m/s. The defender catches the ball carrier in a completely inelastic collision. What was the kinetic energy of the ball carrier/defender system BEFORE the tackle?
Answers
Answer:
3,544.375Joules
Explanation:
Kinetic energy is the energy possessed by a body by virtue of its motion, It is expressed as;
Kinetic energy = 1/2mv²
m is the mass of the body
v is the velocity
For the ball carrier;
KE = 1/2(75)(6.5)²
KE = 3168.75/2
KE = 1584.375Joules
For the defender;
KE = 1/2(80)(7)²
KE = 3920/2
KE = 1960Joules
The kinetic energy of the ball carrier/defender system BEFORE the tackle = KE for the carrier + KE for the defender
kinetic energy of the ball carrier/defender system BEFORE the tackle= 1584.375+1960 = 3,544.375Joules

Consider the moment immediately before the puck is released. At that moment, the kinetic energy, the gravitational potential energy, and the elastic potential energy are, respectively, Select the best answer from the choices provided. a-zero, at a maximum, and at a maximumb-at a maximum, zero, and zeroc-zero, at a maximum, and zerod-at a maximum, at a maximum, and zeroe-zero, zero, and at a maximum
Answers
Answer:
zero, at a maximum, and zero
Explanation:
At the instant that the puck is released, its kinetic energy is zero because we define the kinetic energy of a body as the energy possessed by a body by virtue of its motion.
The gravitational potential energy at the point of release is maximum since gravitational potential energy is possessed by any object in the earth's gravitational field.
Elastic potential energy refers to energy stored in a body as a result of applying a force that deforms the elastic object. . Hence elastic potential energy is available in the puck only when it is deformed upon hitting the earth.

A 45 kg swimmer starting from rest can develop a maximum speed of 12 m/s over a distance of 20 m How much net force must be applied to do this ?
MUST SHOW WORK!
Answers
F = ma = mΔv/t = m(vf - vi)/t = mvf/t (since vi = 0)
⇒ a = vf/t
While accelerating from rest to vf, the distance d the swimmer traveled satisfies
d = (1/2)at2
Then
d = (1/2)(vf/t)t2 = vf t/2 ⇒
t = 2d/vf
F = ma = mvf/t = mvf / (2d/vf) = mvf2 / (2d)
F = [45 * 122 / (2 * 20)] N = 162 N
If you also want to know how long the swimmer took to accelerate to vf,
t = 2d/vf = (2 * 20 / 12) s = 3.33 s
Does temperature affect whether or not a current voltage graph curves?
Answers
Answer:
Current-voltage (I-V) characteristics for components
The relationship between current through, and voltage across, a component is called the current-voltage (I-V) characteristic.
Resistor at constant temperature
For a fixed resistor, the voltage is directly proportional to the current. Doubling the amount of energy into the resistor results in a current twice as fast through the resistor. This relationship is called Ohm's Law and is true because the resistance of the resistor is fixed (because the temperature does not change).
