The speed of an object in a specific direction is expressed in velocity. you do not know an object's velocity until you know speed and distance.
The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity.
The speed of an object in a specific direction is expressed in velocity. Unlike speed, velocity is concerned with the movement's direction.
The difference between velocity and speed is how quickly and in which direction an object moves. Velocity in physics refers to speed in a specific direction. We identify a car's speed when we say it goes at 60 km/h.
Thus, you do not know an object's velocity until you know speed and distance.

Is my definition right?
Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
They subtract the number of protons from the mass number.
They subtract the number of electrons from the mass number.
They subtract the number of protons and neutrons from the mass number.
They add the number of protons and electrons.
Scientists can calculate the number of neutrons by subtracting the atomic number from the atomic mass.
they subtract the protons
The number of neutrons in an isotope of an atom is calculated by subtracting the number of protons from the mass number.
Scientists determine the number of neutrons in an isotope of an atom by subtracting the number of protons from the mass number of the atom. This is because the mass number of an atom is determined by the sum of its protons and neutrons. Therefore, once you know the total mass number and the number of protons, you can easily calculate the number of neutrons by performing a simple subtraction. For example, if an atom has a mass number of 23 and has 11 protons, it would have 12 neutrons (23-11=12).

I think its grasslands
hope this helps!!!
The tying results in the more visible veins of upper arms due to blood flow restriction.
Veins are the part of circulatory system in the body, that functions to carry deoxygenated blood from different parts of the body to the heart.
The venipuncture has been the process of insertion of drugs or chemicals in a body through vein. The veins of the upper arm has been tied to make them more visible.
The upper arm veins are more visible as there has been blood flow restriction in the veins by tying that results in the bulging out of the vein.
