Answer:

The current through R2 is 0.078125 amperes.

Explanation:

Ohm's law is the relationship between electrical conductors and their resistance, which establishes that the current that passes through the conductors is proportional to the voltage applied to them.

Ohm's Law relates the magnitudes of voltage, resistance, and intensity as follows:

V=I*R

where V is the electric potential in volts, I is the current in amperes, and R is the resistance in ohms.

R1 has a 0.200 amperes current  flowing through it and a resistante of 25 ohms.

So:

V=0.200 amperes* 25 ohms

Solving:

V=5 volts

Now, for resistance R2 you know the value of the voltage (5 volts) and the value of its resistance R2 = 64 ohms. So:

5 volts= I* 64 ohms

Solving:

[tex]I=\frac{5 volts}{64 ohms}[/tex]

I= 0.078125 amperes

The current through R2 is 0.078125 amperes.

Answer:

the current through R₂ is 0.078 A

Explanation:

Given;

resistance of the first resistor, r₁ = 25 ohms

resistance of the second resistor, r₂ = 64 ohms

current through the first resistor, I₁ = 0.2 A

The voltage passing through each resistor is constant since they are connected parallel to each other.

V = I₁R₁ = I₂R₂

[tex]I_2 = \frac{I_1R_1}{R_2} \\\\I_2 = \frac{0.2 \times 25}{64} \\\\I_2 = 0.078 \ A[/tex]

Therefore, the current through R₂ is 0.078 A

Explanation:

The net force is the force which is the sum of all the forces acting on an object simultaneously.

Explanation:

The change in entropy is a measure of temperature. When the temperature of a compound or a system increases, there will be more randomness in the system.

The boiling point is directly related to the number of carbon atoms but is indirectly proportional to the branching in a hydrocarbon.

Butane and methyl propane, both have 4 carbon atoms.

But, butane has 4 carbon atoms in a straight chain while methyl propane has 3 carbon atoms in a straight chain and 1 methyl substituent which makes it a branched hydrocarbon.

Thus, the boiling point of methyl propane will be less than the butane. Likewise, the pattern in entropies will be seen.

Answer:

La persona pesa menos

Explanation:

Generalmente, definimos el peso como la fuerza gravitacional que actúa sobre un objeto.

Dado que la constante gravitacional depende del cuadrado de la distancia medida desde el centro de la Tierra, podemos concluir que el peso de un objeto disminuye a medida que aumenta la distancia entre el objeto y el centro de la Tierra (mayor altitud).

Por lo tanto, la persona que pesa 700 N al nivel del mar pesará menos cuando esté en un avión a una altitud de 10,000 m.

Answer:

The apple

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Basically, the potential energy of any physical object is directly proportional to the mass and height of the object. Thus, an increase in either the mass or height of an object would cause an increase in the potential energy possessed by the object.

Hence, an apple weighing 4 ounces would have more potential energy than a cherry that weighs 1 ounce.

Answer:

Length of the wire in meters​ = 0.000628 meter (Approx.)

Explanation:

Given:

Diameter of wire = 0.2 mm

Find:

Length of the wire in meters​

Computation:

Radius of wire = 0.2 / 2

Radius of wire = 0.1

Length of the wire = Circumference of circle

Circumference of circle = 2πr

Length of the wire = 2πr

Length of the wire = 2(3.14)(0.1)

Length of the wire = 0.628 mm (Approx.)

1 meter = 1,000 mm

So,

Length of the wire in meters​ = 0.000628 meter (Approx.)

Answer:

4E

Explanation:

From the question given above, the following data were obtained:

Initial elongation (e₁) = 4 cm = 4/100 = 0.04 m

Initial energy (E₁) = E

Final elongation (e₂) = 0.04 + 0.04 = 0.08 m

Final energy (E₂) =?

The energy stored in a s spring is given by:

E = ½Ke²

Where

E => is the energy

K => is the spring constant

e => is the elongation

From:

E = ½Ke²

Energy is directly proportional to the elongation. Thus,

E₁/e₁² = E₂/e₂²

With the above formula, we can obtain the final energy as follow:

Initial elongation (e₁) = 0.04 m

Initial energy (E₁) = E

Final elongation (e₂) = 0.08 m

Final energy (E₂) =?

E₁/e₁² = E₂/e₂²

E / 0.04² = E₂ / 0.08²

E / 0.0016 = E₂ / 0.0064

Cross multiply

0.0016 × E₂ = 0.0064E

Divide both side by 0.0016

E₂ = 0.0064E / 0.0016

E₂ = 4E

Therefore, the final energy is 4 times the initial energy i.e 4E

The magnitude of your displacement can be equal to the distance you covered, or it can be less than the distance you covered.  But it can never be greater than the distance you covered.

This is because displacement is a straight line, whereas distance can be a straight line, a squiggly line, a zig-zag line, a line with loops in it, a line with a bunch of back-and-forths in it, or any other kind of line.

The straight line is always the shortest path between two points.

Explanation:

The frequency of sound waves received by the microphone influences the output or pitch of the sound obtained from the microphone.

The higher the frequency of the sound received by the microphone, the higher the output of the microphone and vice versa. This is because, the higher the frequency of sound, the higher the oscillations produced and the greater the output of the microphone.

The rise and fall in the pitch of sound waves as the frequency of sound waves varies is called inflection.

b. The car covers a distance x as it stops such that

W = (-725 N) x   ==>   x ≈ 320 m

Answer:

Explanation:

Considering the fact that we ave been given an angle of inclination here, we best use it! That means that the velocity of 23 m/s is actually NOT the velocity we need; I tell my students that it is a "blanket" velocity but is not accurate in either the x or the y dimension of parabolic motion. In order to find the actual velocity in the dimension in which we are working, which is the y-dimension, we use the formula:

[tex]v_{0y}=v_0sin\theta[/tex] and filling in:

[tex]v_{0y}=23sin(25)[/tex] which gives us an upwards velocity of 9.7 m/s. So here's what we have to work with in its entirety:

[tex]v_{0y}=9.7m/s[/tex]

a = -9.8 m/s/s

t = 2.8 seconds

Δx = ?? m

The one-dimensional motion equation that utilizes all of these variables is

Δx = [tex]v_0t+\frac{1}{2}at^2[/tex] and filling in:

Δx = [tex]9.7(2.8)+\frac{1}{2}(-9.8)(2.8)^2[/tex] I am going to do the math according to the correct rules of significant digits, so to the left of the + sign and to 2 sig fig, we have

Δx = 27 + [tex]\frac{1}{2}(-9.8)(2.8)^2[/tex] and then to the right of the + sign and to 2 significant digits we have

Δx = 27 - 38 so

Δx = -11 meters. Now, we all know that distance is not a negative value, but what this negative number tells us is that the ball fell 11 meters BELOW the point from which it was kicked, which is the same thing as being kicked from a building that is 11 meters high.

According to the principle of the Conservation of Energy, energy can neither be destroyed or created, energy can be transformed from form to another

The forms of energy the car has at the different stages is given by virtue of either the position of the car, which is the car's potential energy, or the speed of the car, which gives the potential energy of the car

However, due to the frictional forces acting on the car, there is a frictional force which requires work to be done for the car to move between points in the roller coaster

Therefore, based on the Conservation of Energy principle, we have;

The total energy of the roller coaster, M.E. = m·g·[tex]h_{max}[/tex]

Where;

m = The mass of the roller coaster = 4,500 kg

g = The acceleration due to gravity ≈ 9.81 m/s²

[tex]h_{max}[/tex] = The maximum height = 30 m

Therefore, M.E.[tex]_A[/tex] = 4,500 × 9.81 × 30 = 1,324,350 J

The energy at point B, [tex]M.E._B[/tex] = 4,500×15×9.81 + (1/2) ×4,500×17.15² = 1,323,950.625

The energy at point B, [tex]M.E._B[/tex] = 1,323,950.625 J

At point C, the total energy, [tex]M.E._C[/tex] = (1/2)·m·v²

Where;

v = The velocity of the roller coaster at point c = 24.25 m/s

Therefore;

[tex]M.E._C[/tex] = (1/2) × 4,500 × 24.25² = 1,323,140.625

At point C, the total energy, [tex]M.E._C[/tex] = 1,323,140.625 J

Therefore, given that the energy at point A, M.E.[tex]_A[/tex] is larger than the energy at point B, [tex]M.E._B[/tex], is larger than the energy at point C, [tex]M.E._C[/tex], the loss in energy can be explained by the presence of the friction which require energy for movement of the roller coaster between the points

Let's analyze the situation presented in order to know which answer is correct.

When the stick collides with the puck, it exerts a force for a certain time and discants. / After this time the horizontal force decreases to zero and the disk continues to move by the action of the initial velocity on the x axis and the acceleration of gravity on the y axis.

Therefore, after the collision, the only force that acts on the disk is the gravitational attractive force (WEIGHT), directed on the axis and in a negative direction.

The correct answer is:

C)           Since there is no frictional force exerted on the puck, a normal force is not exerted on the puck, but the gravitational force is exerted on the puck

Explanation:

because the aluminium can still pass current

When the foil is negatively charged, still all of the foil is  made up of aluminum atoms as it has electrons present in it.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
