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?
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 minutesThe 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 sa = (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?
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.

A train travels 9 meters in the first second of travel, 9 meters again during the second second of travel, and 9 meters again during the third second. What is its acceleration?
Answer:
Zero
Explanation:
Acceleration is defined as the rate of change in speed. The speed during the first second is 9m/1s = 9m/s. During the second second is again 9m/1s = 9m/s and again 9m/s for the third second. Being the speed the same, the acceleration is 0

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

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