What voltage is needed to pass a current of 0.5A through a 5k Ω resistor? Show your solution
plzzzzzzzz i need helppppp:)))))
Answer:
V = 2500V
Explanation:
Given the following data;
Current = 0.5A
Resistance = 5K ohms = 5*10³ = 5000 ohms
To find the voltage;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.Substituting into the equation, we have;
[tex] V = 0.5 * 5000 [/tex]
V = 2500 V.
Therefore, the voltage needed to pass the current is 2500 volts.

the mass of the moon is 7.35x10^22 kg and the mass of the earth is 5.97x10^24 kg. the moon’s orbit distance is 3.84x10^8 m. what is the gravitational force on the moon by the earth? what is the gravitational force of the earth on the moon?
Answer:
moon by earth is 1.62/s and squre in mathematical terms and earth by moon is the same answer
Compared to the earth, which has a mass of 5.97 into 10 to the power of 24 kilograms, the moon has a mass of 7.35 into 10 to the power of 22 kilograms. The moon is 3.84 into 10 to the power 8 meters away from the earth, but this is from the center, where the earth cannot see it. We have to judge by the moon.
What is the gravitational force on the moon by the earth?The moon's mass divided by its orbital distance will determine the magnitude of both forces, which will be equal in strength but acting in opposite directions. It is commonplace.
This can be solved within the square as a whole, giving us a result of 19.85 into 10 to the power of 19 newtons. This force will be roughly equivalent to 1.99 into 10 and will have a magnitude of 20 newtons. This will turn out to be the solution to the issue.
The earth will be the moon, and both forces will be moving in the same direction. The force on the moon and the force on earth are the same.
Therefore, The moon's mass is 7.35 into 10 to the power 22, the earth's g square mass is 5.97 into 10 to the power 24, and the r value is 3.84 into 10 to the power 8. Moon by earth is 1.62/s.

How many grams of AB are produced when 88 g of A reacts with 28 g B2?
Answer:
116g
Explanation:
Given parameters:
Mass of A = 88g
Mass of B₂ = 28g
Unknown:
Mass of AB produced = ?
Solution:
The reaction expression is given as:
2A + B₂ → 2AB
According to the law of conservation of matter "matter is neither created nor destroyed but changed from one form to another".
In retrospect;
Mass of A + Mass of B₂ = Mass of AB
Now insert the parameters and solve;
Mass of AB = 88g + 28g = 116g

Katie claims that steel is a homogeneous mixture, even though it looks like a
pure substance. Which statement, if true, would support her claim?
A. Steel contains only iron atoms.
B. Steel is made from iron atoms with clumps of carbon atoms
mixed in.
C. Steel contains carbon and iron atoms, evenly mixed.
D. Steel is made of different compounds distributed unevenly.
Answer:
D. Steel is made of different compounds distributed unevenly.
Explanation:
The statement that will support her claim that steel is a homogenous mixture is that steel is made up of different compounds distributed unevenly.
Steel is an alloy of carbon and iron in its composition. Alloys are classified as mixtures. Their constituent reacts differently to changed medium. The iron in steel does not chemically bond with the carbon.The true statement according to Katie's claim is Steel is made from iron atoms with clumps of carbon atoms mixed in. (option b)
Steel is an alloy composed mainly of iron and carbon, along with other elements in smaller quantities. An alloy is a type of homogeneous mixture where two or more substances are combined at the atomic or molecular level. In the case of steel, it is made by mixing iron atoms with clumps of carbon atoms, and possibly other elements, throughout the material. This means that the carbon and iron atoms are evenly distributed and thoroughly mixed, creating a uniform composition throughout the steel.
Option B is the statement that would support Katie's claim. It correctly describes that steel is made from iron atoms with clumps of carbon atoms mixed in, forming a homogeneous mixture despite its pure-looking appearance.
So, the correct option is (b).

plz. help ) An auto accelerates forward from 7.0 m/s at a uniform
0.71 m/s?. It travels a distance of 1033 m while
accelerating
(a) How fast is the auto moving just as it is traveled
the 1033 m?
(b) How many seconds did it take to travel the 1033 m?
Answer:
The auto is moving at 38.9 m/s
The auto took 45 seconds to travel the 1033 m
Explanation:
Constant Accelerated Motion
it's a type of motion in which the velocity of an object changes uniformly in time.
The relationship between initial and final speeds is calculated by the equation:
[tex]v_f=v_o+at\qquad\qquad [1][/tex]
Where a is the constant acceleration, vo the initial speed, vf the final speed, and t the time.
Another useful equation allows us to calculate the distance x traveled by the object:
[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad\qquad [2][/tex]
(a)
Solving [1] for t and substituting into [2] we find the equation:
[tex]v_f^2=v_o^2+2ax[/tex]
This last equation will be used to solve the first part of the problem which gives the initial speed of vo=7 m/s, the uniform acceleration as a=0.71 m/s^2 and the distance traveled as x=1033 m, thus substituting:
[tex]v_f^2=7^2+2(0.71)(1033)[/tex]
[tex]v_f^2=49+1466.86=1515.86[/tex]
Thus:
[tex]v_f=\sqrt{1515.86}=38.9[/tex]
[tex]v_f=38.9 m/s[/tex]
The auto is moving at 38.9 m/s
(b)
To calculate the time, we solve [1] for t:
[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]
[tex]\displaystyle t=\frac{38.9-7}{0.71}=45[/tex]
The auto took 45 seconds to travel the 1033 m

A 5 kg mass is oscillating on a spring with a time period of 2.8 seconds. What is the spring constant k of the spring?
Answer:
k = 25.18 N/m
Explanation:
Simple Harmonic Oscillator
It consists of a weight attached to one end of a spring being allowed to move forth and back.
If m is the mass of the weight and k is the constant of the spring, the period of the oscillation is given by:
[tex]\displaystyle T=2\pi {\sqrt {\frac {m}{k}}}[/tex]
If the period is known, we can find the value of the constant by solving for k:
[tex]\displaystyle k=m\left(\frac{2\pi}{T}\right)^2[/tex]
Substituting the given values m=5 Kg and T=2.8 seconds:
[tex]\displaystyle k=5 \left(\frac{2\pi}{2.8}\right)^2[/tex]
k = 25.18 N/m
