What did you observe when clear water was poured on the soil around the well? Explain whether it matched your prediction.

Answers

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.

A 100g mass is attached to a string that is 75 cm long. The mass is swung in a horizontal circle that goes around once every 0.80 seconds.
What is the centripetal acceleration of the mass?
What is the tension in the string?

Answers

Answer:

Centripetal acceleration = 46.26m/s2

Tension = 4.6N

Explanation:

Centripetal acceleration is given by the following formula: [tex]a_c = \frac{v^2}{r}[/tex]

So, to calculate acceleration we first need velocity and radius.

The radius is given to us as 75cm = 0.75m, and we can find velocity from the following formula:[tex]v=r\omega[/tex] where w = the angular velocity given by: [tex]\omega = \frac{2\pi}{T}[/tex]

We are given a period of 0.80s, meaning that our angular velocity is:

[tex]\frac{2\pi}{0.80} = 7.85 rad s^{-1}[/tex]

Now we just need to multiply is by the radius to find the velocity:

[tex]0.75*7.85=5.89ms^{-1}[/tex]

Finally we square the velocity and divide by the radius to find the final centripetal acceleration: [tex]\frac{5.89^{2} }{0.75} =46.26ms^{-2}[/tex]

[tex]F=\frac{mv^{2} }{r}[/tex] so we just need to multiply the centripetal acceleration by mass to get the tension force of the string: [tex]46.26*0.1 = 4.6N[/tex]

29.92 inches of mercury and 101,325 pascals are both equivalent to 1 atmosphere of pressure. Calculate the number of pascals equivalent to 1 inch of mercury.

Answers

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

With the above information, we can obtain the number of pascal equivalent to 1 inch of mercury. This can be obtained as follow:

29.92 inches of mercury = 101325 pascal

Therefore,

1 inches of mercury = 101325 / 29.92

1 inches of mercury = 3386.53 pascal

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

A car was traveling on a straight road at a constant speed of 50 kilometers per hour. Over the next two minutes, the car came to travel 80 kilometers an hour. Which of the following is true?

Answers

What are the following options or choices for this question?

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

Acceleration of the car

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

Acceleration of the car over the 2 minutes

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

a = Δv/t

a = (v - u) / t

where;

v is the final velocity = 80 km/h = 22.22 m/su is the initial velocity = 50 km/h = 13.89 m/st is the time of motion, = 2 mins = 120 s

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.

An object on Earth weighs 600 N and on Mars 100 N. If its mass on Earth is approximately 60 kg what is the mass of the object on Mars?

Answers

Answer:

I think its

10 kg

plzz plzz plzz. mark as brainliest

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.

What is mass?

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.

How does the force block A exerts on block B compare to the force block B exerts on block A?

Draw and label a force diagram for each block, using equality marks on the vectors.

Answers

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.
