You will not need any mass to determine the mass of the stick to determine the mass of the meter stick itself.
What is center of mass of a system of particles?A place at which the entire mass of the object or all of the masses of a system of particles appears to be concentrated is considered the center of mass of a body or system of particles.
Only Newton's second law, that also states that an item's mass is equal to its force divided by its mass, may be used to calculate its mass of the object, such as the stick. It is clear that we are unable to determine both force and acceleration values of the stick depicted in the question above.

A flat bottomed boat is floating on the surface of the sea. The boat weighs 20,000 N and the surface area of its hull is 4 m2. Calculate the water pressure that acts on the hull of this boat.
To calculate the water pressure that acts on the hull of the boat, we can use the equation:
Pressure = Force / Area
The force acting on the hull is the buoyant force, which is equal to the weight of the water displaced by the boat. Since the boat is floating, the weight of the water displaced is equal to the weight of the boat. Therefore:
Force = Weight of boat = 20,000 N
The area of the hull that is in contact with the water is 4 m2
Therefore, the water pressure acting on the hull of the boat is:
Pressure = Force / Area = 20,000 N / 4 m2 = 5000 N/m^2
The pressure unit is Newtons per square meter (N/m^2) also known as Pascals (Pa).
It's important to note that the weight of the boat and the water displaced are in Newtons and the area of the hull is in square meter, that's why the pressure is in N/m^2.

Acid rain is the result of pollutants being released into the air
What is acid rain ?Acid rain is defined as rain or any other type of precipitation that is unusually acidic, which means it contains a lot of hydrogen ions. Acid rain has a pH level that is lower than this and typically ranges from 4-5. Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5.
When gases like sulphur dioxide and nitrogen oxides are released into the atmosphere, a chemical reaction takes place that eventually results in acid rain.

The magnitude of the vector 6i-2j +3k is
A vector's length determines its magnitude. It is also known as the vector's absolute value or its absolute modulus. The Pythagorean theorem is used to determine a vector's magnitude.
The length of a given vector, let's say v, is determined using the magnitude of a vector formula, which is indicated as |v|. In essence, this amount represents the distance between the vector's beginning point and ending point. The vector's length is its magnitude, and its direction is the direction it is pointing.
With just a few straightforward steps, it is simple to calculate a vector's magnitude. Finding the cross product, the angle between two vectors, and adding and subtracting vectors are further crucial vector operations.

What's the difference between Newton's first law and inertia?.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an unbalanced force. In other words, it states that an object will remain in a state of constant velocity unless acted upon by a net external force.
Inertia, on the other hand, is the property of an object that resists a change in its state of motion. It is the tendency of an object to maintain its current state of motion (i.e. at rest or in motion) unless acted upon by an external force. Inertia is a fundamental concept in physics and is closely related to Newton's first law.
So in summary, Newton's first law is a statement about the behaviour of an object in motion and the relationship between force and motion, while inertia is a property of an object that describes its resistance to a change in motion.

For the first bullet, kinetic energy is 480 J and for the second bullet, kinetic energy is 1920 J.
What is kinetic energy?Kinetic energy is the energy possessed by an object or a particle due to its motion. It is the energy of motion and can take many forms, such as the energy associated with an airplane flying through the air, a ball rolling down a hill, a person running, or a car traveling on a highway. In general, kinetic energy is the energy an object has because of its movement.
The kinetic energies of the two bullets can be calculated using the equation KE = (1/2)mv2, where m is the mass of the object and v is the velocity of the object.
For the first bullet, KE = (1/2)(3.0 g)(40.0 m/s)2 = 480 J.
For the second bullet, KE = (1/2)(3.0 g)(80.0 m/s)2 = 1920 J.

Does mass depend on speed?.
No, mass and speed are two different physical quantities that do not have any direct relationship.
Mass is a scalar quantity that measures the amount of matter in an object, it is independent of its location or motion and it is constant. It is the same whether an object is at rest or in motion.
Speed, on the other hand, is a measure of how fast an object is moving. It is the distance an object travels in a certain amount of time and it can change. For example, an object can be moving at a high speed or at a low speed.
In the theory of special relativity, mass and energy are closely related and, as a result, the mass of an object increases as it approaches the speed of light. But this is only for objects that are moving at a velocity close to the speed of light, but for everyday objects, mass does not depend on speed.

Does gravity depend on size or density?.
Gravity depends on mass, not on size or density.
Gravity is a force of attraction between two objects that have mass. The force of gravity is proportional to the product of the two masses and inversely proportional to the square of the distance between them. Therefore, the more massive an object is, the stronger the gravitational force it exerts.
Size and density are not directly related to gravity. Size is a measure of how big an object is, and density is a measure of how much mass is contained in a given volume. They do not affect the strength of the gravitational force. An object's size or density may affect the gravitational force acting on it, but only through their effect on the object's mass.
