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 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?
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]
Hope this helped!
You and your dad are pushing your car out of the mud. You apply a force of 200 N and your dad applies a force of 250 N. What is the net force? Will the car move and if so, in what direction?
A. 450 N, yes, in the direction of the pushing
B. 0 N, no
C. 50 N, yes, in the direction of the dad
Answer:
I believe it's A (450 N)
Explanation:
Since both you and your dad are pushing in the same direction, you must add the force N to get the net force, which in this case in 450 N

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.

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

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.
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 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
