Answer:
Explanation:
The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers.

¿Qué trabajo efectúa una fuerza de 110 N para recorrer un desplazamiento de 20 m si el ángulo entre las direcciones de la fuerza y el desplazamiento es de 30 grados?
El trabajo de la fuerza aplicada es 1905 J
Los datos del problema son
Fuerza F = 110 N, La distancia recorrida d = 20 m El ángulo entre la fuerza y el desplazamiento θ = 30º
El trabajo se define por el producto escalar entre la fuerza y el desplazamiento, las letras en negrita indican vectores
W = F. D
Donde W es el trabajo, F la fuerza, d el desplazamiento y el punto representa el producto escalar,
W = F d cos θ
Esta expresión es un escalar y θ es el ángulo entre la fuerza y la distancia
Calculamos el trabajo
W = 110 20 cos 30
W = 1905 J
Donde J es la unidad de trabajo
El trabajo de la fuerza que es un escalar es 1905 J

A constant force acts on a body causing the momentum of the body
to increase. Which expression relates the force to the momentum and the time taken?
The expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].
Let the constant force causing change in momentum, = FLet the time of force action = t
The impulse experienced by the body at the given constant force and time is calculated as follows;
[tex]J = \Delta P = mv[/tex]
where;
ΔP is change in momentum
The force acting on a body is given by Newton's second law of motion;
[tex]F = ma\\\\F = \frac{mv}{t} \\\\Ft = mv\\\\Ft = \Delta P\\\\F = \frac{\Delta P}{t}[/tex]
Thus, the expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].
