discuss one way in which global warming aggravates the effect of radiation​

Answers

The energy that then radiates out from the surface, longwave radiation, is trapped by the same greenhouse gases, warming the air, oceans, and land. This process, appropriately dubbed “the greenhouse effect,” is how global warming occurs.

One way by which global warming aggravates the effect of radiation is through greenhouse effect

The combined effects of global warming and radiation is explained as follows.

Global warming is the gradual increase in the temperature of the Earth's surface (land), ocean and the atmosphere through the heat from the radiation of the sun.

One way by which global warming aggravates the effect of radiation is through greenhouse effect.

This occurs when the radiation from the sun is allowed to pass into the Earth's atmosphere but subsequent heat radiating from the Earth is prevented from escaping into the space.

This greenhouse effect aggravates the effect of radiation.

BRAINLIEST : A car starts from rest and accelerates at a rate of 40 m/s2 over a time if 2.4 s. How fast is the car going at the end of this time interval?

Please explain

Answers

Answer:

[tex]\boxed {\boxed {\sf 96 \ m/s}}[/tex]

Explanation:

We are asked to find the final velocity of the car given the acceleration and time. We can use the following kinematics equation to calculate the final velocity.

[tex]v_f=v_i+(a \times t)[/tex]

The car starts from rest, so the initial velocity is 0 meters per second. It accelerates a rate of 40 meters per square second over a period of time of 2.4 seconds.

[tex]v_i[/tex]= 0 m/s a= 40 m/s²t= 2.4 s

Substitute the values into the formula.

[tex]v_f= 0 \ m/s + ( 40 \ m/s^2 \times2.4 \ s)[/tex]

Solve inside the parentheses.

40 m/s/s * 2.4 s = 40 m/s * 2.4=96 m/s

[tex]v_f= 0 \ m/s + (96 \ m/s)[/tex]

Add.

[tex]v_f= 96 \ m/s[/tex]

The final velocity of the car is 96 meters per second.

Name an acid which is highly corrosive and should never be tested by mouth.​

Answers

Answer:

We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach

It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.

HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.

The ball is hurled upward into space, it climbs steadily until it collides with an obstruction in its path.

What is gravitational force?

All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.

As we know, the gravitational force is given by:

[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]

Where G is the gravitational constant.

m1 and m2 are masses.

r is the distance between the masses.

As we know,

There is no gravity in space, the ball is not subject to the effects of gravity. When a ball is hurled upward into space.

It climbs steadily until it collides with an obstruction in its path.

Thus, the ball is hurled upward into space, it climbs steadily until it collides with an obstruction in its path.

Give a reasonable order-of-magnitude estimate of the number of golf balls that would fill a home
swimming pool

Answers

An order of magnitude is a number of the form 10^n such that can be used to compare magnitudes or quantities.

We will find that  the order of magnitude of golf balls that fill a home swimming pool is 10^6

In this case, we want to estimate the number of golf balls that would fill a home swimming pool.

We know that the diameter of a golf ball is D = 42.6mm = 0.0426m

And the volume of a sphere of diameter D is:

V = (4/3)*pi*(D/2)^3

where pi = 3.14

Then the volume of a single golf ball is:

V =  (4/3)*3.14*( 0.0426m/2)^3 = 0.00004 m^3

Now we need to find the average volume of a home swimming pool, we can use 48 m^3 (an average one) to do the general math.

To find the number of golf balls that enter in that volume, we need to do the quotient between the volume of the pool and the volume of a single ball:

N = (48 m^3)/(0.00004 m^3)  = 1,200,000

If we round this to the next order of magnitude: 10^6 (the exponent is the number of digits at the right of the one)

Then the order of magnitude of golf balls that enter in a home swimming pool is  10^6
