ong>Answer:

Soil erosion inhibits our ability to grow nutritious FOOD. By decreasing the nutrients available to plants as well as the space for them to put down roots, soil erosion can DECREASE crop yields by up to 50 percent. In ADDITION, crops that do grow tend to be of a lower quality: misshapen, SMALLER and less nutritious.

Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by MITOSIS each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new GENERATION the NUMBER of chromosomes would double

Given:-

• A stone thrown vertically upwards with initial velocity " u ".

• Reaches a height " h " before COMING down.

To Prove:-

• The time taken to go up is same as the time taken to come down.

Proof:-

Here, We have to use the equation of motions,

v = u + at               -------------------- (1)

v² = u² + 2as         -------------------- (2)

Where v is the final velocity after time t, u is initial velocity, a is acceleration and s is DISTANCE travelled in time t.  

Let u be the initial velocity of stone.

when the stone reaches the maximum height after time t , its final velocity is zero.

When the stone TRAVELLING vertically upwards, it is experiencing the retardation due to gravity.

hence, we write the above equation of motion (1) as,  

      -------------------- (3)

equation (2) will be written as,   0 = u2 - 2×g×h, or

      ------------------- (4)

by substituting u from equation (4) in equation (3), we have t

    ------------------- (5)

After reaching maximum height, the stone descends with zero initial velocity,  accelerated downwards due to gravity and reaches the ground after time t'.

Equations (1) and (2) are written as follows for downward travel

        -------------- (6)

            ------------------- (7)

from equation (4) and equation (7), we can conclude that initial velocity and  final velocity when the stone reaches the ground are equal.

by substituting for v from equation (7) in equation (6), we get

      ----------------------- (8)

from equation (5) and equation (8),  time of ascending the height h is equal to time of descending from same height h.

Hence, The time taken to go up is same as the time taken to come down.

                    ------------------------- Proved ---------------------------

Explanation:

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and MESOPOTAMIA in around 3000 to 1200 BCE  (Long Answer)

Both are correct

n heart have four chambers right atrium, right ventricle, left atrium and left ventricle.

The superior VENA cava, inferior vena cava and coronary sinus brings deoxygenated blood from all body parts expect lungs and SUPPLY it to right atrium.

• Superior vena cava brings the blood from upper portion of the body.
• Inferior vena cava brings the blood from lower portion.
• Coronary sinus bring the blood from WALLS of the heart.

Right atrium pumps the blood into the right ventricle and send it to the PULMONARY artery.

Pulmonary artery sends deoxygenated blood from right ventricle to lungs for oxidation.

There are 2 pairs of Pulmonary veins which brings oxygenated blood from lungs and supply it to left atrium.

Left atrium pumps the blood to the left ventricle and left ventricle sent is to the Aorta.

Aorta supply oxygenated blood from left ventricle to all parts of the body.

stion :-

• The resistance of a wire is 100 ohm.If it carries a CURRENT of 1Amp for 10seconds the heat produced will be ___.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Given that :-

• Resistance of a wire = 100 ohm
• Correct flowing through it = 1 A.
• Time = 10 SEC.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

To FIND :-

• Heat produced

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Formula to be used :-

• Heat = I²Rt

ㅤ‎‎‎‎ㅤㅤWhere, I = current

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎R = resistance

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎t = time.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Solution :-

Heat produced in circuit = I²Rt

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎ㅤㅤㅤㅤ= (1)² × 100 × 10

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎ㅤㅤㅤㅤ= 1000 JOULE.

THEREFORE, heat produced = 1000 Joule.

ong>Answer:

When methane reacts with chlorine a SUBSTITUTION reaction occurs and the organic product is chloromethane.

2 NaOH (s) + CO2 (g) →Na2CO3 (aq) + H2O (L) This MEANS that solid reagent grade sodium hydroxide is not pure enough to weigh and use directly. Furthermore, the carbonate ion interferes in acid-base titrations because 1) it is a weak base, and 2) it tends to make the color change at the end point less sharp.

If you test a reaction that releases heat, the temperature of the water will increase. Hydrocarbon fuels like methane (CH4) burn in the presence of oxygen to produce carbon dioxide and water. This process of combustion releases energy.
