Answer:

When water is added to soil, it can replace the oxygen that is naturally in the soil, and make the soil darker. This means wetter soil will have less oxygen compared with drier soil. When enough water is added, soil can become saturated and the water will start to form a layer on top of it.

Explanation:

The acceleration of the car over the 2 minutes is 0.07 m/s².

The acceleration of an object is the rate of change of velocity of the object with time.

The acceleration of the car over the 2 minutes is calculated as follows;

a = Δv/t

a = (v - u) / t

where;

a = (22.22 - 13.89) / 120

a = 0.07 m/s²

Thus, the acceleration of the car over the 2 minutes is 0.07 m/s².

If the mass of an object is approximately 60 kg on earth then its mass remains the same on Mars which is 60 kg because mass does not change from place to place.

Mass in physics is a numerical representation of inertia, a fundamental property of all matter. What a body of matter is fundamentally is the resistance it offers to a change in its speed or location brought on by the application of a force. The more mass a body has, the less of a change a force exerts results. The kilogram is the unit of mass in the International System of Units, and it is defined by Planck's constant as being equal to 6.62607015 × 10⁻³⁴ joules second (SI).

According to the question, the weight of an object depends on gravity which is different from place to place so weight also varies from place to place but the mass is constant everywhere it does not change. So, if the mass of an object is 60 kg on earth then it remains the same on mars also.

By Newton's third law, we will see that the force that block A exerts on block B is equal in magnitude but in opposite direction than the force that block B exerts on block A.

Remember that Newton's third law says that whenever two objects interact, they exert equal and opposite forces on each other.

The force that block B exerts on block A is equal to block B's weight, which is:

[tex]W_b = 0.05kg*9.8m/s^2 = 0.49 N[/tex]

Then the force that block A exerts on block B is equal in magnitude but in opposite direction, thus it will be equal to:

F' = -0.49N

Then the diagram is the one that you can see below.

The number of pascal equivalent to 1 inch of mercury is 3386.53 pascal

From the question given above, we were told that:

29.92 inches of mercury = 1 atm

101325 pascal = 1 atm

Thus,

29.92 inches of mercury = 101325 pascal

29.92 inches of mercury = 101325 pascal

Therefore,

1 inches of mercury = 101325 / 29.92

Thus, the number of pascal equivalent to 1 inch of mercury is 3386.53 pascal
