Answer:
my middle school life was horrible and still is sadly ); could you please do my recent brainless <333
Explanation:
My middle school life was eh.i allways got assumed that i was a elementry kid when i was and 6 and 7 grade.until 8th when i hit my grow spurt.my voice end up getting really deep in 8th grade too.tho in 8th i got sent to a certain type of scholl for kids who did bad because of some dum teacher who lied that i hit her when i actually just went to her desk to get my phone sence she saw it in my pocket and took it away.i got sent there for 3 months and was worst thing ever.the treated us like prisoners in that school and made us tacky uniforms that i refused to where.i believe it was a school for 7th-12th.after my expierence at that school my expierence in 8th grade was almost done.i end up being popular at school for being that kid who hit the teacher.ofc that was like 2 years ago im 10th now.i dont really remember my 6th and 7th grade year.only thing i rember is i was a trouble maker and still am a trouble maker.
hope that helped you:)

Does temperature affect whether or not a current voltage graph curves?
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).
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
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.

Most of our Solar system is composed of___
asteroids
moons
planets
empty space
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."
Which way can heat never flow?
Answer:
Cold to hot.
Explanation:
Heat can never flow from cold to hot, heat transfers itself from hot to cold.
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
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.

Explanation:
a metallic cube whose each side is 10 cm is subjected to a shearing force of 100 kg. The top force is displaced through 0.25 cm with respect to the bottom. calculate the shearing stress strain and modulus
Answer:
9.8×104Nm−2,0.025,3.92×106Nm−2
Solution :
Here, L=10cm=10×10−2m
F=100kgf=100×9.8N
ΔL=0.25cm=0.25×10−2m,
Shearing stress =FL2=100×9.8(10×10−2) Sheraing strain =ΔLL=0.25×10−210×10−2 = 0.025 Shear Modulus of elasticity, G=Shearing stressShearing strain=9.8×1040.025
=3.92×106Nm−2

what is one standard kilogramun si system
Answer:
The kilogram (kg) is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10−34 when expressed in the unit J s, which is equal to kg m2 s−1, where the meter and the second are defined in terms of c and ∆νCs.

A 60 N force is applied over distance of 15 m. How much work was done? ( show work)
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.
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 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
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]

(m/s)
Brass
4,700
Air

A. 2.3 m
B. 0.43 m
C. 0.043 m
D. 23.5 m
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

What are the advantages and Disadvantages of using Circuit Breakers Instead of Fuses
Answer:
Explanation:
Circuit breaker is an automatic electrical switch which cuts the power when there is surge in current.
Advantages of Circuit breaker
They are more reliable i.e. they are not replaced frequentlyEfficient and easy to safeguard electrical applianceDisadvantage of Circuit breaker
They are less sensitive than fuses i.e. fuses are much faster than circuit breaker.Answer:
The benefits are defined throughout the section described according to the particular context.
Explanation:
Just before it completes its function, users should substitute a fuse, although circuit breakers work through a trigger where you essentially restart or reboot. Fuses become composed of such a lump of material (metal) that can explode when enough electric current is passed through everything, disturbing another circuit successfully therefore stopping the equipment from hitting another power outage.
