Answer:

1. troposphere

2. troposphere (still)

3. The most abundant gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.

4.The stratosphere is where you'll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection.

5. It contains the ozone, which protects Earth from the sun's radiation. Why aren't there many meteors in the troposphere? They burn up before they reach the troposphere.

Explanation:

1.The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere. Temperature and water vapor content in the troposphere decrease rapidly with altitude.

2.The layer closest to Earth's surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.

The equivalent resistance for the parallel connected resistance will be

[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω)

Now if two resistances are connected parallel then the voltage on the resistances will be different and the same current will flow from both resistances.

[tex]V_{eq}=V_1+V_2[/tex]

[tex]I_{eq}R_{eq}=I_1R_1+I_2R_2[/tex]

Since [tex]I_{eq}=I_1=I_2[/tex]

[tex]R_{eq}=R_1+R_2[/tex]

Hence the equivalent resistance for the parallel connected resistance will be

[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

Answer:

2.304 × 10^-28 N

Explanation:

Compute the force on each of two electrons when they are seperated in vaccum by a distance corresponding to the approximate size of an ato. (0.100nm)

Solution

The formula to use is

F = K Qq / r^2

Substitute all the parameters

F = 9 × 10^9 × (1.6 × 10^-19)^2 / (0.1 × 10^-9)^2

F = 2.304 × 10^-28 / 1 × 10^-10

F = 2.304 × 10^-18 N

Therefore, the force between each of the electron is 2.304 × 10^-18 N

Answer:

Work hasn't been done by Michael because no distance was covered.

Explanation:

Workdone is given by the formula;

[tex] Workdone = F * s[/tex]

Where;

W is the work done

F represents the force acting on a body.

s represents the distance covered by the body.

Hence, work hasn't been done by Michael because no distance was covered, as the table didn't move at all. Therefore, work done is zero.

Answer:

Λ = 2 t

Explanation:

This is a problem is interference by reflection, where it is requested not to take into account the changes of phase and change in the wavelength within the film

                   λₙ = λ₀ / n

When the wave enters the film, it must reach the end of the film, be reflected and reach the initial surface, therefore the total length is

                d = 2 t

where t is the thickness of the film, because the film is perpendicular to the surface

therefore the difference in optical path between the reflected ray on the surface and the end film is

                  Λ = 2 t

Question: A negative 6 mC charge enters a region of 45 T magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s. determine the magnitude and  direction of the force

Answer:

Magitude of F = 108 N

Direction: Perpendicular to the plane containing v and B.

Explanation:

From the question,

Since the velocity of the charge(v), is parallel to the field(B).

Therefore, We apply

F = qvB..................Equation 1

Where F = Force, B = magnetic field, v = velocity, q = Charge.

Given: q = 6 mC = 0.006 C, v = 400 m/s, B = 45 T

Substitute these values into equation 1

F = 0.006×400×45

F = 108 N.

The direction of the force is always perpendicular to the plane containing v and B.

the angular velocity is related to the period

         w = 2π / T

we substitute

Law 2:

Pushing a baby on a swing is easier than pushing an adult on the same swing. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

Law 2:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

Law 1:

A magician pulls a tablecloth out from under a dish on a table without disturbing the dish.

Law 3:

A rocket launches into space, pushing fuel exhaust in one direction and the rocket in the opposite direction.

Law 1:

A book rests on top of a shelf and does not move until a student accidentally knocks it off.

Explanation:

Newton's laws of motion:

Law 1: Law of inertia

Law 2: Law of force (F = mass x acceleration)

Law 3: Law of Action & Reaction

The laws followed by the given situations are Newton's law of force, Law of inertia and Newton's third law.

Inertia is defined as the tendency of an object to continue its state of rest or motion.

Here,

Considering the situations given,

1. Pushing a baby on a swing is easier than pushing an adult on the same swing.

This is because, the mass of the baby is lesser than that of the adult. So, according to Newton's force equation,

Force, F = ma

Therefore to push a body with more mass, more force should be applied.

Another situation that follows this law from the given situations is:

When thrown with the same force, a soccer ball accelerates more than a bowling ball.

2. Water spills from a glass carried by someone who is walking steadily and suddenly stops short.

This is due to the inertia of the water in the glass. This can be explained by law of inertia.

Explanation:

The shovel shifts the course of the man's force.

Man can use less power.

The strength at the end of the shovel is growing.

Its shovel is a tool that is used to excavate and transfer its large particles. This streamlines the job for all the men to find the pit.

Its machines modify their method that uses force. Its man must therefore use less force to lift the bulk material.

Answer:

The shovel changes the direction of the force the man applies.

The man can apply less force.

The force applied by the end of the shovel increases.

Explanation:

From the question we are told that

1st distance [tex]d_1=752 m[/tex]

2nd distance [tex]d_2=587 m[/tex]

Generally the total distance [tex]d_t[/tex]covered by the man is mathematically given as

[tex]d_t=752+587\\d_t=1339m[/tex]

Generally the resultant distance traveled is mathematically given as

[tex]d_r^2=d_1^2+d_2^2[/tex]

[tex]d_r=\sqrt{752^2+587^2}[/tex]

[tex]d_r=953.98[/tex]

Generally the angle  using sine rule traveled is mathematically given as

Actually Welcome to the concept of Efficiency.

Here we can see that, the Input work is given as 2.2 x 10^7 J and the efficiency is given as 22%

The efficiency is => 22% => 22/100.

so we get as,

E = W(output) /W(input)

hence, W(output) = E x W(input)

so we get as,

W(output) = (22/100) x 2.2 x 10^7

=> W(output) = 0.22 x 2.2 x 10^7 => 0.484 x 10^7

hence, W(output) = 4.84 x 10^6 J

The useful work done on the mass is 4.84 x 10^6 J

Answer:

The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°

Explanation:

The direction of the force acting on a conductor through which a charge flows  is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field

Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
