What might be done to prevent acid rain damage to objects made from metal and carbonate, such as limestone? Identify a metal object that could be damaged by acid rain. Then, describe what could be done to prevent acid rain damage to it.

Answer air circulating in a hot air balloon

Explanation:

Answer:

466J

Explanation:

Given parameters:

Mass of steel  = 1kg  = 1000g

Initial temperature  = 21°C

Final temperature  = 22°C

Unknown:

Amount of heat required for this temperature increase  = ?

Solution:

To solve this problem, we use the expression below:

  So;

Heat absorbed  = mass x specific heat of steel x change in temperature

Specific heat of steel  = 0.466J/g°C  

Therefore;

 Heat absorbed  = 1000 x 0.466 x (22  - 21)  = 466J

Answer:

The warmer air mass rises, and there will be clouds and rain.

Explanation:

The less dense air mass will rise.

In the given scenario, the warmer air mass rises, and there will be clouds and rain. The correct option is B.

A large volume of air in the atmosphere that is mostly uniform in temperature and moisture is referred to as an air mass.

Air masses can travel thousands of kilometers across the Earth's surface and reach all the way to the stratosphere.

In the horizontal direction, air masses have fairly uniform temperature and moisture content but not uniform in vertical.

The temperature and humidity properties of air masses define them. The underlying surface properties where air masses originate determine their properties.

The warmer air mass rises as a new air mass moves into an area, causing clouds and rain.

Thus, the correct option is B.

Answer:

Retar is nothing but a Bad acceleration.

Answer:

neurofibromatosis also calles von Recklinghausen's disease.

Answer:

17.6 m/s²

Explanation:

Given:

[tex]v_{f}[/tex] = 90 m/s (final velocity)

[tex]v_{i}[/tex] = 2 m/s (initial velocity)

Δt = 5s (change in time)

The formula for acceleration is:

[tex]a_{avg}[/tex] = Δv / Δt

We can find Δv by doing

Δv = [tex]v_{f}[/tex] - [tex]v_{i}[/tex]

Replace the values

Δv = 90m/s - 2m/s

Δv= 88m/s

Using the equation from earlier, we can find the acceleration by dividing the average velocity by time.

[tex]a_{avg}[/tex] = Δv / Δt

[tex]a_{avg}[/tex] = [tex]\frac{88m/s}{5/s}[/tex]

acceleration = 17.6 [tex]m/s^{2}[/tex]

Answer:

15m

Explanation:

change in real depth = 80 - 60 = 20m

Let us assume that the index is 4/3

Refractive index = change in real depth ÷ change in apparent depth

change in apparent depth = change in real depth÷ refractive index

= 20÷(4/3) = 20×(3/4) = 5×3 = 15m

The image that shows an example of the strong nuclear force in action should be considered option d.

The strong nuclear force is known as the  strong force or the strong interaction.

This force is strong when it overcomes the repulsive force that lies between the two positively charged protons where the neutrons and protons should be permitted for sticking together.

Hence, The image that shows an example of the strong nuclear force in action should be considered option d.

Answer:

v = 2 m/s

Explanation:

First, we find the angular velocity of the girl by using the following formula:

[tex]Angular\ Velocity =\omega= \frac{Angular\ Distance\ Covered}{Time\ Taken}\\\\\omega = \frac{1\ revolution}{10\ min}\frac{1\ min}{60\ s}\frac{2\pi\ rad}{1\ revolution}\\\\\omega = 0.01\ rad/s[/tex]

Now, for the average velocity of the girl we can use the following formula:

[tex]Average\ Velocity = V = r\omega\\V = (200\ m)(0.01\ rad/s)\\[/tex]

where,

r = radius = 200 m

therefore,

v = 2 m/s

Answer:

Explanation:

Answer:

Let the mass of the book be "m", acceleration due to gravity be 'g", velocity "v" and height be "h".

Now if we are holding a book at a certain height (h), the potential energy will be maximum which is equal to mass×acceleration due to gravity× height (=mgh).

(Remember: kinetic energy=0)

Now we consider that the book is dropped, in this case a force will act downward towards the centre of the earth, Force=mass×acceleration due to gravity (F=mg). It is equal to the weight of the book.

While the book is falling, the potential energy stored in the book converts into kinetic energy and strikes the floor with the maximum kinetic energy=(1/2)×mass×velocity² (=1/2mv²).

(Remember: potential energy=0)

Due to the process the whole energy is conserved.

As potential energy decreases kinetic energy increases.

False.

Explanation:

Human diversity means differences among people. Therefore, it's each of us in our rich and infinite indistinguishable features; this is basically the fundamental building block of culture. For example, a doctor might enjoy watching football and educational documentary programs while another enjoys listening to music and watching thriller movies.

Culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

This ultimately implies that, culture are acquired and passed from one generation to another.

A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication. Thus, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
