The current across the circuit is equal to 0.833A if a voltage source of 5 V is connected at the input.
What is Ohm's law?Ohm’s law states that the potential difference across a circuit is directly proportional to the current flowing through it. Assuming temperature and all other physical conditions remain constant. Resistance's S.I. unit is rho (Ω), and the current raises the temperature.
The mathematical expression of potential difference provided by Ohm/s law is:
V = IR
Where V is the voltage difference and R is the resistance and I the current flowing.
Given, the resistances in a series circuit, R = 3 + 3 = 6 ohm
The voltage difference across the circuit, V = 5 V
The current flowing through the circuit will be:
V = I × R
I = V/R
I = 5/6
I = 0.833 A
Therefore, the current across the circuit is equal to 0.833 A.

1) Un perito fue encomendado para determinar si un trozo de metal muy parecido al oro de 0,75 kg. Y de volumen 340 cm3. Era en verdad dicho metal, use las características de la densidad de un cuerpo para ayudar al perito.
Answer:
Primero, sabemos que la densidad de el oro es:
Densidad = 19.3 g/cm^3
Sabemos que nuestro metal tiene una masa de 0.75 kg, y un volumen de 340 cm^3.
Primero deberíamos reescribir la masa en gramos, pues la densidad está escrita en gramos.
Sabemos que:
1 kg = 1000g
Entonces:
0.75 kg es 0.75 veces 1000g, esto nos da:
0.75kg = 0.75*(1000g) = 750g
Entonces tenemos:
masa = 750g
volumen = 340cm^3
Ahora debemos recordar que:
densidad = masa/volumen
Entonces la densidad de este metal es:
densidad = 750g/340cm^3 = 2.21 g/cm^3
Si la comparamos con la densidad del oro, podemos ver que esta es mayor.
Entonces podemos concluir que este metal no es oro.
Solve for x and y algebraically:
x + y = 8 and 3x + 2y = 21
Explanation:
ans ...(5,3)..............
Answer:
x = 5
y = 3
Explanation:
x + y = 8 and 3x + 2y = 21
Here We use Substitution Method
x + y = 8 ...(1)
3x + 2y = 21 ...(2)
From equation (1) we get
x + y = 8
x = 8 - y
Now the value of x = 8 - y in equation (2)
3(8 - y) + 2y = 21
24 - 3y + 2y = 21
- y = 21 - 24
y = 3
Then Put the value of y in equation (1)
x + (3) = 8
x + 3 = 8
x = 8 - 3
x = 5
Thus The value of x is 5 and y is 3
For Verification Only:x + y = 8
5 + 3 = 8
8 = 8
3x + 2y = 21
3(5) + 2(3) = 21
15 + 6 = 21
21 = 21

Which statement best explains the difference between light waves traveling through a vacuum and light waves traveling through a medium?
Answer:
The statement which best explains the difference between the light waves travelling through a vaccuum and light waves travelling through a medium is -"When light waves travel through a vacuum, they travel faster than when they travel through a medium."
Explanation:
Light waves are faster in vacuum because The refractive index of vacuum is the lowest since there is no barrier in the way of light propagation in vacuum. Demonstrate that the maximum speed of light in vacuum.
In a vacuum, light flies at 186,283 mph. Light flies at 186,200 mph in the air, or 56 mph slower. In another medium, such as water, light travels at 139,712 mph, or around 3/4 of the speed of light in a vacuum.
LIGHT WAVES -: Light waves are a form of electromagnetic wave that includes both visible and invisible to the naked eye wavelengths on the electromagnetic spectrum. The average human eye can see light with wavelengths ranging from 390 to 700 nanometers, or nm.
Forms of light waves comprises of Radio waves , microwaves , infrared waves , visible light etc.
When light waves travel through a vaccume, they travel faster than when they travel through a medium

Atmospheric pressure on that day is 1.0 multiply 10 to the power of 5 Pa. calculate the total pressure at the bottom of the pond
Answer:
Water pressure P=ρgh (density X acceleration due to gravity X height of water)
P=1000X9.8x3=29,400 N/m2 or Pascal
But there is air pressure over water which also adds to the pressure at the bottom of the pool.
Therefore,Atmospheric pressure over the water=1.01 x 105 N/m2
So the total pressure on the bottom of the pool = 29,400+ 101000 Pa
= 130,400 Pa

Find the energy of a 50kg object that is moving at 4m/s
If 550 J of work is done to pull a box horizontally across the floor 4.6m, what is the force of friction between the box and floor?
The work done is the product of the force and resulted displacement. The frictional force between the box and floor is 119.5 N.
What is force?Force is external factor acting on a body to make a change in the state of an object . According to Newton's second law of motion, force is the product of mass and acceleration.
The work done in physics is the product of force acting on a body and its displacement. Therefore, the force which result in a displacement of the body is said to be work done on the object.
Here, the work done by frictional force is 550 J and displacement is 4.6 m.
Therefore, the force = work done / displacement
= 550 J/ 4.6 m
= 119.5 N.
Hence, the force between the floor and box will be 119.5 N.

8.0 Kg of water is heater from 20°C to 40°C. The specific heat capacity of water is 4200 J/Kg °C. What is the energy supplied to the water?
Answer:
672000 J.
Explanation:
From the question,
q = cm(t₂-t₁)............................ Equation 1
Where q = heat energy supplied to the water, c = specific heat capacity of water, m = mass of water, t₂ = final temperature, t₁ = Initial temperature.
Given: m = 8.0 kg, c = 4200 J/kg°C, t₂ = 40°C, t₁ = 20°C
Substitute these values into equation 1
q = 8×4200×(40-20)
q = 8×4200×20
q = 672000 J.
Hence the energy suplied to the water is 672000 J.
Per Bernoulli's Principle, low velocity = ____ pressure.
A. high
B. medium
C. low
D. no
Answer:
A. high pressure
Explanation:
Bernoulli's equation is given as;
[tex]P_2 + \frac{1}{2} \rho v_2^2 + \rho gh_2 = P_1 + \frac{1}{2} \rho v_1^2 + \rho gh_1\\\\P_2 = P_1 + \frac{1}{2}\rho (v_1^2 - v_2^2) + \rho g(h_1-h_2)[/tex]
Based on the equation above, it can be seen that an increase in velocity (from v₁ to v₂ ) causes a decrease in pressure (P₂), while a decrease in velocity will cause an increase in pressure.
Therefore, Per Bernoulli's Principle, low velocity = high pressure.

1) At point X, the gall is at an elevation higher than the thrower, therefore, the ) ball has (gravitational) potential energy, GPE, because it can fall to a lower level unassisted from the height it was thrown
And the ball is also in upward motion, with which it reaches the height 'Y', therefore, the ball has kinetic energy, KE, to move higher
2) At point 'Y' which is the maximum height, the ball no longer moves upwards and momentarily, the ball has no vertical motion, therefore, the ball has only energy due to height, which is the gravitational potential energy, GPE
3) At the point Z, at the instant just before the ball touches the ground, the elevation of the ball above the ground is small, while the velocity of the ball is close to maximum velocity, therefore, the ball has Only kinetic energy, KE
