Find the acceleration of a body of mass 300g being acted upon by a force of 6N.

Please show the working

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.

Answer:

[tex]\boxed {\boxed {\sf 243.75 \ J }}[/tex]

Explanation:

Kinetic energy is energy an object has due to motion. The formula is:

[tex]KE=\frac {1}{2}mv^2[/tex]

The mass of the object is 78 kilograms and the velocity is 2.5 meters per second.

[tex]m= 78 \ kg \\v= 2.5 \ m/s[/tex]

Substitute the values into the formula.

[tex]KE= \frac {1}{2} (78 \ kg)*(2.5 \ m/s)^2[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Solve the exponent first.

[tex]KE= \frac {1}{2}(78 \ kg)*6.25 \ m^2/s^2[/tex]

Multiply all three numbers together.

[tex]KE=39 \ kg * 6.25 \ m^2/s^2\\[/tex]

[tex]KE=243.75 \ kg*m^2/s^2[/tex]

1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 243.75 kg *m²/s² is equal to 243.75 Joules.

[tex]KE=243.75 \ J[/tex]

The object has 243.75 Joules of kinetic energy.

Answer:

[tex]d_t=1339m[/tex]

[tex]d_r=953.98[/tex]

[tex]x=37.975 \textdegree[/tex]

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 =1st\ distance +2nd\ distance[/tex]

[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

let angle =x

[tex]\frac{sin90}{d_r} =\frac{sinx}{587}[/tex]

[tex]sinx=\frac{sin90*587}{953.98}[/tex]

[tex]x=37.975 \textdegree[/tex]

Answer:

nun

Explanation:

Answer:

Godzilla

Explanation:

Answer: The sun's rays strike Earth's surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.

The light is most intense where it strikes Earth's surface most directly at the equator

Answer:

15.7 ; 78.5

Explanation:

Given that

The mechanic use a screw driver to install 1⁄4-20 UNC bolt

And, the effort force is 5lb

We need to find out the mechanical advantage

And, the resistance force

As we know that

The Mechanical advantage of a screw = Circumference ÷ pitch

where,  

Circumference = pi × d

 pi = 3.142, D = diameter

So,  

Circumference = 3.142 × (1 ÷ 4)

= 0.785 in

Now

Pitch = 1 ÷ TPI

Here TPI (thread per inch) = 20

Pitch = 1 ÷  20 = 0.05

So,

Mechanical advantage = 0.785 ÷ 0.05

= 15.7

Now Resistance force if effort force is 5lb

We know that

Mechanical advantage = Fr ÷ Fe

Here

Fe = effort force, Fr = resistance force

15.7 = Fr ÷ 5

Fr = 15.7 × 5

= 78.5 lbs

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:

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

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.

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.

Answer:

I think B) is uncorrect

Explanation:

As A) p=w/t so it's correct relation

C) power depend on time and work as work is distance multiple force so it refer to velocity

D) the powerful mean much work in a few time

Answer:

12 N

Explanation:

Given that a 12 kg object's velocity changes from 5 m/s to 10 m/s in 5 s, what amount of force was applied to increase the speed of the object?

Solution

M = 12 kg

T = 5 s

The formula to use will be

F = ma

Where

Acceleration a = change in velocity/ time

Acceleration a = ( 10 - 5 ) / 5

Acceleration a = 5 / 5

Acceleration a = 1 m/s^2

Substitutes a into the formula above

F = ma

F = 12 × 1

F = 12 N

Therefore, the amount of force applied to increase the speed of the object is 12 N.

To accurately respond to stimuli, the brain relies on information communicated by sensory neurons. Sensory neurons detect inputs from the environment, convert them into signals (electrical impulses), and pass the information on to the brain and spinal cord, where a response can be generated.

Explanation:

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

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:

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.
