Answer 1

Based on the nature of friction:

the box did not slide off the table before you put enough coins in the bag due to friction.The coefficient of the friction of the rough surface is greater than that of the smooth surfaceThe difference is due to the nature of the surfaces.Human errors could occur if the coins are not added carefullythe coefficient of friction is a constant for a given surface and independent of the mass of the object.

What is friction?

Friction is the opposition to the relative motion of an object over another at their surfaces of contact.

The coefficient of friction is a ratio of the frictional force and the normal reaction.

Coefficient of friction = frictional force/normal reaction

The coefficient of friction of rough surfaces is greater than that of smooth surfaces.

In the given experiment:

the box did not slide off the table before you put enough coins in the bag because of friction between the box and the tableThe coefficient of the friction of the rough surface is greater than the coefficient of friction of the smooth surfaceThe difference between the two values of coefficient of friction is due to the nature of the surfaces.Human errors in the experiment could occur when the coins are not added carefullyThe coefficient of friction of each surface is constant and independent of the mass

A force of 1.5 × 102 n is exerted on a charge of 1.4 × 10–7 c that is traveling at an angle of 75° to a magnetic field. if the charge is moving at 1.3 × 106 m/s, what is the magnetic field strength?

Answers

The magnetic field strength = 8.5 x 10² T.

Solution :

the magnetic force Fm is given by

Fm= q V B sinθ

q= charge=1.4 x 10⁻⁷ C

v= velocity= 1.3 x 10⁶ m/s

B= magnetic field strength

Fm= magnetic force= 1.5 x 10² N

θ=75°

so 1.5 x 10²=(1.4 x 10⁻⁷) (1.3 x 10⁶ ) (B) sin75

B=8.5 x 10² T

Magnetic field strength: The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.

A wire carries a 4.0-A current along the +x-axis through a magnetic field B= (5.0 i+7.0 j) T. If the wire experiences a force of 30 N as a result, how long is the wire?

Answers

Hello!

The equation for the magnetic force experienced by a wire is:
[tex]F_B = B \times iL[/tex]

F = Magnetic force on wire (30 N)

B = Magnetic field strength (5.0i + 7.0j)

i = Current in wire (4.0 A)
L = Length of wire (? m)

This is a CROSS-PRODUCT. We can rewrite this as:
[tex]F_B = BiLsin\theta[/tex]

Where 'θ' is the angle between the magnetic field and the current carrying wire.

Therefore, we would NOT count any field that is parallel to the wire. The field does have a component (5.0i) that is along the x-axis, so we would NOT count it because the wire is along this same axis.

This leaves the 'j' component, which is PERPENDICULAR to the wire. θ would then be 90°, and sin(90) = 1.

[tex]F_B = B\hat{j} iL[/tex]

Solving for the length:
[tex]L = \frac{F_B}{B\hat{j} i}\\\\L = \frac{30}{7(4)} = \boxed{1.07 m}[/tex]

Using the knowledge of shadows and reflection, advice the barber on how to arrange a good saloon using the only item he has. Without adding more source of light, how can he enhance the lighting system in his saloon?​

Answers

According to the information, it can be inferred that the best way to distribute the chairs and mirrors is to put the light system on a wall and put the 3 mirrors and chairs in front of the light as shown in the image.

How to distribute the objects to take advantage of the light from the bulb?

To take advantage of the light from the bulb for the three chairs and the three mirrors, the objects must be placed in such a way that all three receive enough light to be able to carry out the work of cutting the hair.

So, the best option would be to put the bulb in the middle of a wall, and place a chair and mirror in front of the bulb. The other two chairs should be located one on each side of the centered chair and the mirrors in front of each chair.

There is a current of 0.83 A through a lightbulb in a 120 V circuit. What is the resistance of this lightbulb?

Answers

Considering the Ohm's law, the resistance of the lightbulb is 144.58 Ω.

Definition of current

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measure is amps (A). So the current is a measure of the speed at which the charge passes a given reference point in a specified direction.

Definition of voltage

The driving force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Definition of resistance

Resistance (R) is the difficulty that a circuit opposes to the flow of a current and it is measured in ohms (Ω).

Ohm's law

Ohm's law establishes the relationship between current, voltage, and resistance in an electrical circuit.

This law establishes that the intensity of the current that passes through a circuit is directly proportional to the voltage of the same and inversely proportional to the resistance that it presents.

Mathematically, Ohm's law is expressed as:

[tex]I=\frac{V}{R}[/tex]

Where:

I is the current measured in amps (A).V the voltage measured in volts (V).R the resistance that is measured in ohms (Ω).

Resistance of the lightbulb

In this case, you know that the voltage between two points in a circuit is 120 V and there is a current of 0.83 A.

Replacing in the Ohm's Law:

[tex]0.83A=\frac{120 V}{R}[/tex]

Solving:

0.83 A× R=  120 V

[tex]R=\frac{120 V}{0.83A}[/tex]

R= 144.58 Ω

Finally, the resistance of the lightbulb is 144.58 Ω.

Taking into account the definition of solvent and solute, helium is the solute and oxygen is the solvent.

Definition of solute and solvent

The solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.

That is, the solute and the solvent are the components of a chemical solution, that is, of a homogeneous mixture that occurs when one or more substances are dissolved in another substance.

The solute is the substance that dissolves in a solution. In solution, the solute is usually found in a lower proportion than the solvent.

Solvent is the substance in which a solute dissolves, resulting in a chemical solution. Generally, the solvent is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.

What is a parallel plate capacitor?

The two parallel plates placed at a distance apart are used to store charge when the electric supply is on.

The capacitance of a capacitor in series is given by:

Series capacitance = 1/ capacitance 1 + 1/ Capacitance2

The capacitance of a capacitor in parallel series can be calculated as:

Parallel capacitance = Capacitance 1 + Capacitance 2

In the following circuit,

C1=10.0 F,

C2=2*10.0 F,

C3=2*10.0 F,

C4=2*9.4 F, and

C5=3*9.4.

In the circuit C2 and C3 are in parallel, their equivalent capacitance is

= 2*10.0 F+2*10.0 F

= 4 *10.0 F

Then, C1 is in series with 4 *10.0 F,

So their equivalent capacitance is

=1 /{ 1/10.0 F + 1/ 4 *10.0 F}

=0.8*10.0 F

C4 and C5 are in series, their equivalent is

=1 /{ 1/2*9.4 F + 1/3*9.4 F}

=0.75*9.4 F

Now,0.8*10.0 F and 0.75*9.4 F are in parallel.

Total equivalent capacitance is Ceq = 0.8*10.0 F + 0.75*9.4 F

Ceq = 15.05 F

Thus, the equivalent capacitance in the circuit is  15.05 F.

Answers

Answer:

50+20=70

70÷5=14

Explanation:

50×20=1000

1000÷5=200

Answer:

Approximately [tex]20\; {\rm s}[/tex], assuming no energy loss and that [tex]g = 10\; {\rm N \cdot kg^{-1}}[/tex].

Explanation:

If the gravitational field strength is constantly [tex]g[/tex], lifting an object of mass [tex]m[/tex]  by a height of [tex]\Delta h[/tex] would increase the gravitational potential energy ([tex]\text{GPE}[/tex]) of that object by [tex]m\, g\, \Delta h[/tex].

In this question, [tex]m = 20\; {\rm kg}[/tex] and [tex]\Delta h = 5\; {\rm m}[/tex]. Assume that [tex]g = 10\; {\rm N \cdot kg^{-1}}[/tex]. Hence, the [tex]\text{GPE}[/tex] that this object would eventual gain would be:

[tex]\begin{aligned}m\, g\, \Delta h &= 20\; {\rm kg} \times 10\; {\rm N \cdot kg^{-1}} \times 5\; {\rm m} \\ &= 1000\; {\rm N \cdot m} \\ &= 1000\; {\rm J}\end{aligned}[/tex].

Thus, this motor would need to do (at least) [tex]1000\; {\rm J}[/tex] of work to lift this object up by [tex]5\; {\rm m}[/tex]. The power rating of this motor, [tex]P = 50\; {\rm W} = 50\; {\rm J \cdot s^{-1}}[/tex], means that (assuming no energy loss) this motor could do [tex]50\; {\rm J}[/tex] of work every second.

The time it would take for this motor to do [tex]1000\; {\rm J}[/tex] of work under these assumptions would be:

[tex]\begin{aligned}t &= \frac{\text{work}}{\text{power}} \\ &= \frac{1000\; {\rm J}}{50\; {\rm J \cdot s^{-1}}} \\ &= 20\; {\rm s}\end{aligned}[/tex].

[tex]v &= \omega r\sin \theta \\ v &= \left( {7.29 \times {{10}^{ - 5}}} \right)\left( {6.37 \times {{10}^6}} \right)\sin 47^\circ \\ v &= 339.62\;{\rm{m/s}}[/tex]

Part (c):

The acceleration of the object can be calculated as,

[tex]a &= \dfrac{{{v^2}}}{{r\sin \theta }}\\ a &= \dfrac{{{{339.62}^2}}}{{6.37 \times {{10}^6}\sin 47^\circ }}\\ a &= 0.024\;{\rm{m/}}{{\rm{s}}^{\rm{2}}}[/tex]

Scott FitzgeraldAfter dark on Saturday night one could stand on the first tee of the golf-course and see the country-club windows as a yellow expanse over a very black and wavy ocean. The waves of this ocean, so to speak, were the heads of many curious caddies, a few of the more ingenious chauffeurs, the golf professional's deaf sisterand there were usually several stray, diffident waves who might have rolled inside had they so desired. This was the gallery.The balcony was inside. It consisted of the circle of wicker chairs that lined the wall of the combination clubroom and ballroom. At these Saturday-night dances it was largely feminine; a great babel of middle-aged ladies with sharp eyes and icy hearts behind lorgnettes and large bosoms. The main function of the balcony was critical, it occasionally showed grudging admiration, but never approval, for it is well known among ladies over thirty-five that when the younger set dance in the summer-time it is with the very worst intentions in the world, and if they are not bombarded with stony eyes stray couples will dance weird barbaric interludes in the corners, and the more popular, more dangerous, girls will sometimes be kissed in the parked limousines of unsuspecting dowagers.To what does Fitzgerald compare those who peer into the country club's windows on Saturday night?the guards in a prisonwaves on the oceanbarbariansladies with icy hearts
