We will have that as long as the object is a conductor it will be able to have a net negative charge of 2.00*10^-9 C.

Answer:

0.60s

Explanation:

Using the motion equation as follows:

S = ut + 1/2gt²

Where;

S = distance travelled (m)

u = initial velocity (m/s)

t = time (s)

g = acceleration due to gravity (m/s²)

Based on the information provided, S = 1.8m, u = 0m/s, t = ?

S = ut + 1/2gt²

1.8 = (0×t) + 1/2 (9.8t²)

1.8 = 0 + 4.9t²

1.8 = 4.9t²

t² = 1.8/4.9

t² = 0.3673

t = √0.3673

t = 0.6060

t = 0.60s

Explanation:

The density is what determines if it will float. Lower densities float, while higher densities sink. Density takes mass and volume into account.

The relationship that determines an object's ability to float in a liquid is option : "Density of the object < Density of the liquid."  The option 3 is correct.

This principle is known as Archimedes' principle. When an object is placed in a fluid (liquid or gas), it experiences a buoyant force that opposes the force of gravity. The buoyant force is determined by the difference in density between the object and the fluid it's immersed in. If the density of the object is lower than the density of the liquid, the object will experience a greater buoyant force, causing it to float. Conversely, if the object's density is greater than the density of the liquid, it will sink. Hence option 3 is correct.

Given :

Solenoid 2 has twice the radius and six times the number of turns per unit length as solenoid 1.

To Find :

The ratio of the magnetic field in the interior of 2 to that in the interior of 1.

Solution :

We know, magnetic field in the interior of a solenoid is given by :

\(B = \dfrac{\mu ni}{L}\)

Let, length of solenoid 2 is L.

Therefore, length of solenoid 1 is 6L.

\(B_a=\dfrac{\mu (6n)i}{L}\\\\B_b = \dfrac{\mu n i}{L}\)

Dividing \(B_a\) by \(B_b\) :

\(\dfrac{B_a}{B_b}=\dfrac{\dfrac{\mu (6n)i}{L}}{\dfrac{\mu n i}{L}}\\\\\dfrac{B_a}{B_b}=6\)

Therefore, the correct answer is C. 6.

In the given position-versus-time graph, the object moving the slowest without being at rest is at point B.

A position-versus-time graph illustrates how far an object has traveled from its starting position at any given time since it started moving. The vertical axis represents the position of the object, and the horizontal axis represents the time.

The slope of the graph indicates the speed of the moving object. Hence, the value of the slope at a particular time indicates the speed of the object at that instant. Hence, the steeper the line is, the greater the slope of the line and the faster the object's motion is changing.

In the given graph, at point A, C and E the slope is zero the object is not moving, hence at rest. At point D slope is steeper as compared to slope at point B. Hence, object is moving slower at point B compared to point D.

Explanation:

First option is correct.Larry the Rock is going through Static Equilibrium.

In this situation, Larry is at rest and remains stationary despite the forces acting on him. While David and Pancho are exerting equal forces from opposite sides, their forces cancel each other out, resulting in a net force of zero. As a result, Larry does not move or experience any acceleration.

Static equilibrium occurs when an object's forces and torques balance each other, leading to a stable, balanced state. In this case, the forces exerted by David and Pancho are equal in magnitude and opposite in direction, creating a condition where the resultant force is zero. As a result, Larry remains in a state of rest, unable to experience any movement or acceleration.Therefore, the type of equilibrium that Larry the Rock is going through is Static Equilibrium.

Answer:

I know the answer

Explanation:

We want to choose the film thickness such that destructive interference occurs between the light reflected from the air-film interface (call it wave 1) and from the film-lens interface (call it wave 2). For destructive interference to occur, the phase difference between the two waves must be an odd multiple of half-wavelengths.

You can think of the phases of the two waves as second hands on a clock; as the light travels, the hands tick-tock around the clock. Consider the clocks on the two waves in question. As both waves travel to the air-film interface, their clocks both tick-tock the same time-no phase difference. When wave 1 is reflected from the air-film boundary, its clock is set forward 30 seconds; i.e., if the hand was pointing toward 12, it's now pointing toward 6. It's set forward because the index of refraction of air is smaller than that of the film.

Now wave 1 pauses while wave two goes into and out of the film. The clock on wave 2 continues to tick as it travels in the film-tick, tock, tick, tock.... Clock 2 is set forward 30 seconds when it hits the film-lens interface because the index of refraction of the film is smaller than that of the lens. Then as it travels back through the film, its clock still continues ticking. When wave 2 gets back to the air-film interface, the two waves continue side by side, both their clocks ticking; there is no change in phase as they continue on their merry way.

So, to recap, since both clocks were shifted forward at the two different interfaces, there was no net phase shift due to reflection. There was also no phase shift as the waves travelled into and out from the air-film interface. The only phase shift occured as clock 2 ticked inside the film.

Call the thickness of the film t. Then the total distance travelled by wave 2 inside the film is 2t, if we assume the light entered pretty much normal to the interface. This total distance should equal to half the wavelength of the light in the film (for the minimum condition; it could also be 3/2, 5/2, etc., but that wouldn't be the minimum thickness) since the hand of the clock makes one revolution for each distance of one wavelength the wave travels (right?).

Answer:

The more the mass, the more the gravity. The more the distance the less the gravity.

Explanation:

ANSWER

EXPLANATION

Parameters given:

Mass, m = 30 kg

Distance above the ground, d = 5 m

To find the amount of work that gravity does on the mass, we have to find the product of its weight and the distance of the mass above the ground:

where F represents weight (since it is a force)

The weight of the mass is:

where g = acceleration due to gravity

Hence, the work done by gravity is:

At every point during the mass's fall to the ground, it possesses both potential and kinetic energy, although in varying quantities at different points.

Hence, yes, it has energy in it.

Just before the mass hits the ground, its final kinetic energy is equal to its initial potential energy.

To find the speed of the mass, we have to first find that potential energy.

Potential energy is given by:

That is equivalent to its kinetic energy just before it hits the ground.

Kinetic energy is given by:

where v = speed

Now, we can solve for speed from the formula above:

That is the speed of the mass just before it hits the ground.

Answer:

7 protons, 8 neutrons, 7 electrons

Explanation:

Protons, electrons and neutrons are three sub-atomic particles present in an atom. Protons and neutrons are present in the nucleus while electrons are present outside the nucleus.

The number of protons, which is also the ATOMIC NUMBER, is equal to the number of electrons in a neutral atom (no overall charge). In this case, the number of protons is 7, however, since the charge of this Nitrogen atom is 0, it means that the number of electrons is also 7.

The mass number, denoted by A, is the sum of the number of protons and neutrons in an atom i.e.

A = number of proton + number of neutron.

In this case of Nitrogen isotope where the mass number is 15, the number of neutron will be mass number - number of protons i.e. 15 - 7 = 8.

Therefore, the number of protons, neutrons and electrons are 7, 8 and 7 respectively.

The total displacement as it travels between Emily and Luisa if Emily passes a soccer ball 5 m directly across the field to Ara, who then kicks the ball 12.5 m directly down the field to Luisa, is 17.5 meters.

All locations in a body that are moved from one state to another are assigned displacement vectors. The difference between a trajectory point's final and starting positions is known as displacement (for instance, the center of mass of a moving object). The precise route taken to arrive at the destination is not important.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a lecturer moves to the right in relation to a whiteboard. Displacement describes this shift in location.

The displacement is the total distance from one place to another, so, when Emily passes a soccer ball 5 m directly to the era and then the total displacement is equal to the total distance traveled by the football.

The total distance traveled by the ball = 5 + 12.5 = 17.5 meters.

Usually, we use sampling when a population is hard to study, for some reason.

Sampling is a technique commonly employed in research and statistics when it is impractical or impossible to study an entire population directly. It involves selecting a subset, or sample, from the population and using the information gathered from the sample to make inferences about the entire population. This is done with the assumption that the sample is representative of the population and that the findings from the sample can be generalized to the larger population.

There are several reasons why a population might be difficult to study comprehensively. One reason is the size of the population. For example, if the population of interest is the entire world or a country, it would be practically impossible to study each individual in the population due to logistical constraints and limited resources. In such cases, sampling allows researchers to gather information from a smaller, manageable subset of the population.

Another reason for using sampling is when the population is dispersed or geographically scattered. If the population is spread out across a wide area, it can be challenging and costly to reach and collect data from every individual. Sampling allows researchers to select representative individuals or clusters from different regions, making data collection more feasible.

Additionally, there are cases where the population is inaccessible or hard to reach due to privacy concerns or ethical considerations. For example, if the population consists of individuals with certain medical conditions or sensitive personal information, it may be challenging to obtain consent or access to the entire population. In such cases, researchers can use sampling methods to obtain data from a subset of individuals who are willing to participate and meet the necessary criteria.

In summary, sampling is a valuable tool when studying populations that are hard to access, too large, or dispersed. It allows researchers to gather relevant data from a representative subset of the population and make valid inferences about the larger population, despite the challenges posed by studying the population as a whole.

The total resistance of the circuit is 49 Ω. The current strength in the circuit, when connected to a voltage source of 56 V, is approximately 1.14 A.

To calculate the total resistance of the circuit, we need to determine the equivalent resistance of the resistors connected in a series.

Given:

R1 = 4 Ω

R2 = 30 Ω

R3 = 10 Ω

R4 = 5 Ω

Calculate the equivalent resistance (RT) of R1 and R2, as they are connected in series:

RT1-2 = R1 + R2

RT1-2 = 4 Ω + 30 Ω

RT1-2 = 34 Ω

Calculate the equivalent resistance (RTotal) of RT1-2 and R3, as they are connected in parallel:

1/RTotal = 1/RT1-2 + 1/R3

1/RTotal = 1/34 Ω + 1/10 Ω

1/RTotal = (10 + 34) / (34 * 10) Ω

1/RTotal = 44 / 340 Ω

1/RTotal ≈ 0.1294 Ω

RTotal ≈ 1 / 0.1294 Ω

RTotal ≈ 7.74 Ω

Calculate the equivalent resistance (RTotalCircuit) of RTotal and R4, as they are connected in series:

RTotalCircuit = RTotal + R4

RTotalCircuit = 7.74 Ω + 5 Ω

RTotalCircuit ≈ 12.74 Ω

Therefore, the total resistance of the circuit is approximately 12.74 Ω.

To determine the current strength (I) when connected to a voltage source of 56 V, we can use Ohm's Law:

I = V / RTotalCircuit

I = 56 V / 12.74 Ω

I ≈ 4.39 A

Therefore, the current strength in the circuit, when connected to a voltage source of 56 V, is approximately 4.39 A (or 1.14 A, considering significant figures).
