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.

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.

Explanation:

In essence, this means that planets do not travel along their orbits at a constant speed. Instead, they move at different speeds so that the line connecting the centres of the Sun and the planet covers the same amount of ground in equal amounts of time. Thus, option A is correct.

The law of areas is Kepler's second law of planetary motion. A line drawn between a planet and the Sun is said to cover equal areas in an equivalent amount of time according to this law.  

The velocity of a planet as it travels along its elliptical course is described by Kepler's Second Law. An elliptical object will cover equal amounts of space in a same amount of time if a line is drawn from the sun to the planet. This implies that the planet moves more slowly away from the sun and faster toward it.

Therefore, at equal times, the planet must cover a wider arc when it is nearer the Sun than when it is farther away.

last time i wrote the wrong answer for the wrong problem :)

For the constant speed, the resultant force on the plane is 0N. So, the correct option is A.

A force is defined as the parameter that can change the momentum of an object that can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or pull where force has both magnitude and direction, making it a vector quantity.

For above given information, the plane is moving at a constant speed. According to Newton's first law, the net external force on the aircraft due to the thrust generated by the propeller must be zero and air resistance is equal and in opposite directions to produce zero net force.

Thus, for the constant speed, the resultant force on the plane is 0N. So, the correct option is A.

The temperature of a gas will increase and the density will decrease as it

expands.

The expansion of gas  happens as a result of an increase in the elastic

collision of the atoms. This is as a result of the increase in temperature which causes the atoms to be more spatially arranged.

The density of gas also reduces as a result of the same number of gas

molecules occupying more volume.
