Answer 1

Answer:

R = 4Ω

Explanation:

If we have two resistors with resistances R1 and R2 in series the total resistance is R = R1 + R2

If the resistances are in parallel, the total resistance is given by:

1/R = 1/R1 + 1/R2.

First, we have a resistor with R1 = 1.5Ω

This resistor is connected in series with a parallel part (let's find the resistance of this parallel part), in one branch we have two resistors in series with resistances:

R2 = 8Ω and R3 = 4Ω

Because these are in series, the resistance of that branch is:

R = 8Ω + 4Ω = 12Ω

In the other branch, we have a single resistor of R4 = 4Ω

The resistance of the parallel part is:

1/R = 1/12Ω + 1/4Ω = 1/12Ω + 3/12Ω = 4/12Ω = 1/3Ω

1/R = 1/3Ω

R = 3Ω

Then we have a resistor (the first one, R1 = 1.5Ω) in series with a resistor of 3Ω.

Then the total resistance is:

R = 1Ω + 3Ω = 4Ω

1. A massive object can distort the light of more distant objects behind it through the phenomenon that we call ________. 2. ________ are defined as subatomic particles that have more mass than neutrinos but do not interact with light. 3. The _____________ of spiral galaxies provide strong evidence for the existence of dark matter. 4. Models show that the _________ of the universe is better-explained when we include the effects of dark matter along with the effects of luminous matter.

Answers

Answer:

1. Gravitational lensing.

2. Weakly interacting massive particles (WIMPs).

3. Rotation curves.

4. Large-scale structure.

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are; solid, liquid and gas.

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

The following statements are matched to give the characteristics of matter with respect to light;

1. A massive object can distort the light of more distant objects behind it through the phenomenon that we call: gravitational lensing. The gravitational field distorts and magnifies light from a distant galaxy such as quasars.

2. Weakly interacting massive particles (WIMPs): are defined as subatomic particles that have more mass than neutrinos but do not interact with light.

3. The rotation curves of spiral galaxies provide strong evidence for the existence of dark matter.

4. Models show that the large-scale structure of the universe is better-explained when we include the effects of dark matter along with the effects of luminous matter.

The distance between 4 nodes (3 sections, 2 sections= wavelength) is 15.0cm. The frequency of the source is 10Hz. What's the speed of the waves in cm/s?

Answers

Answer:

the speed of the waves is 150 cm/s

Explanation:

Given;

frequency of the wave, f = 10 Hz = 10

distance between 4 nodes, L = 15.0 cm

The wavelength (λ) of the wave is calculated as follows;

Node to Node = λ/2

L = 2(Node to Node) = (4 Nodes) = 2 (λ/2) = λ

Thus, λ = L = 15.0 cm

The speed (v) of the wave is calculated as follows;

v = fλ

v =  10 Hz   x  15.0 cm

v = 150 cm/s

Therefore, the speed of the waves is 150 cm/s

Consider 2 steel rods, A and B, B has three times the area and twice the length of A, so young modulus of B will be what factor times young modulus of A?

Answers

Answer:

  [tex]\frac{Y}{Y_o}[/tex] = 2/3

Explanation:

The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain

         Y =  [tex]\frac{ \frac{F}{A} }{\frac{\Delta L}{L_o} }[/tex]

let's use the subscript "o" for rod A

         I = [tex]\frac{ \frac{F}{A_o} }{ \frac{\Delta L}{L_o} }[/tex]

tells us that rod B has

         A = 3 A₀

         L = 2 L₀

we substitute

         Y = [tex]\frac{ \frac{F}{A} }{ \frac{\Delta L}{L} }[/tex]

          Y = [tex]\frac{ \frac{F}{3A_o} }{ \frac{\Delta L}{ 2L_o} }[/tex]

         y = ⅔  [tex]\frac{ \frac{F}{A_o}}{ \frac{\Delta }{L_o} }[/tex]

substituting the value of Y₀

          Y = ⅔  Y₀

           [tex]\frac{Y}{Y_o}[/tex] = 2/3

Using a horizontal force of 60 N, a wagon is pushed horizontally across the floor a distance of 12 meters at a constant speed of 2.3 m/s
a) What is the work done by the force?
b) What is the power supplied by the force?

Answers

Answer:

a) The work done by the force is 720 joules, b) The power supplied by the force is 138 watts.

Explanation:

a) Since force is uniform and parallel to the direction of motion, the work ([tex]W[/tex]), in joules, done by the force ([tex]F[/tex]), in newtons, is defined by this formula:

[tex]W = F\cdot s[/tex] (1)

Where [tex]s[/tex] is the travelled distance, in meters.

If we know that [tex]F = 60\,N[/tex] and [tex]s = 12\,m[/tex], then the work done by the force is:

[tex]W = F\cdot s[/tex]

[tex]W = (60\,N)\cdot (12\,m)[/tex]

[tex]W = 720\,J[/tex]

The work done by the force is 720 joules.

b) And an expression for the power supplied by the force ([tex]\dot W[/tex]), in watts, is concieved by differentiating (1) in time:

[tex]\dot W = F\cdot \dot s[/tex]

Where [tex]\dot s[/tex] is the speed of the wagon, in meters per second.

If we know that [tex]F = 60\,N[/tex] and [tex]\dot s = 2.3\,\frac{m}{s}[/tex], then the power supplied by the force is:

[tex]\dot W = F\cdot \dot s[/tex]

[tex]\dot W = (60\,N)\cdot \left(2.3\,\frac{m}{s} \right)[/tex]

[tex]\dot W = 138\,W[/tex]

The power supplied by the force is 138 watts.

A turtle swimming in a straight line toward shore has a speed of 0.50 m/sec. After 4.0 seconds, its speed is at 0.90 m/sec. What is the turtle's acceleration?​

Answers

Answer:

0.1m/s²

Explanation:

Using the equation of motion

V = u+at

V is the final speed = 0.9m/s

Initial speed u = 0.5m/s

Time = 4secs

Get the acceleration

0.9 = 0 5+4a

0.9-0.5 = 4a

0.4 = 4a

a = 0.4/4

a = 0.1m/s²

Hence the acceleration is 0.1m/s²

The heat current across a certain cinductive material is H. If the cross-sectional area of the material is tripled and everything else remains the same, how is the heat current affected?

Answers

Answer:

Resistance is inversely proportional to the cross section area of the material, hence when cross sectional area is tripled, also resistance triples.

Since heat is caused due to resistance, also heat current triples.

A 3kg object moving at 4 m/s encounters a 20 N resistive force over a duration of 0.20 seconds. The impulse experienced by this object is _____

Answers

Answer:

the impulse experienced by this object is 4 Ns

Explanation:

Given;

mass of the object, m = 3 kg

velocity of the object, v = 4 m/s

resistive force, F = 20 N

duration of impact, t = 0.2 s

The impulse experienced by this object is calculated as follows;

J = F x t

J = 20 x 0.2

J = 4 Ns
