Answer:

The face of the cube towards A. is bright and shiny and the face towards B is dull black. State with reason the adjustments that should be made on the distances X1 and X2 so that the rate of change of temperature in both balloons is the same.

Explanation:

Convection is the mechanism by which heat is transferred from the cube to the balloon. Convection is the movement of currents inside a liquid or gas that transfers heat energy.

Convection is a method of heat transfer in which a fluid or gas, such as air or water, is moved. A hotter liquid or gas loses density and rises, while a colder, denser liquid or gas replaces it by sinking. Convection is the term used to describe the movement of gases or liquids due to temperature differences.

When the cube is heated, the air around it becomes less dense and rises; On the contrary, the cold air from all around fills the space. As a result, heat energy is transferred from the cube to the balloons via convection currents.

Therefore, Convection is the mechanism by which heat is transferred from the cube to the balloon. Convection is the movement of currents inside a liquid or gas that transfers heat energy.

Answer:

The magnitude of the point charge is 3.496 x 10⁻⁶ C

Explanation:

Given;

radius of the surface, r = 14.3 m

magnitude of the potential, V = 2.2 kV = 2,200 V

The magnitude of the point charge is calculated as follows;

[tex]V = (\frac{1}{4\pi \epsilon _0} )(\frac{Q}{r} )\\\\V = \frac{KQ}{r} \\\\Q = \frac{Vr}{K} \\\\Q = \frac{2,200 \times 14.3}{9\times 10^9} \\\\Q = 3.496 \times 10^{-6} \ C\\\\Q = 3.496 \ \mu C[/tex]

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.

b. Fuse.

c. Source.

d. Wire.

e. Switch.

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, fuse, etc.

Matching the given circuit parts to their appropriate functions, we have;

a. Load: an appliance or device that uses electricity source like bulbs, computers, television, radio, etc.

b. Fuse: it is a safety device made from materials that easily melt even before the wires carry too much current.

c. Source: it is where electricity came from like batteries and generators.

d. Wire: it is the pathway of electricity from the resources (source) to the load.

e. Switch: it controls the flow of electricity from the source. It is typically used to turn ON or turn OFF a load.

The formula for the magnitude of this resultant vector, which is in Q1, btw, is:

[tex]B_{mag}=\sqrt{6.18^2+4.43^2}[/tex] which gives us, to 3 sig fig's:

7.60 m. Since the resultant vector is in Q1, we don't need to add anything to the angle once we find it to 3 sig fig:

[tex]tan^{-1}(\frac{4.43}{6.18})[/tex] gives us an angle of 35.6 degrees

multiplication of two vectors yields a vector oroduy

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:

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.

#SPJ2

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:

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

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

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.)
