Answer:
Conociendo la velocidad inicial del proyectil y el angulo de lanzamiento con respecto ala horizontal.
Explanation:
Para poder anticipar la caída del proyectil es importante conocer la velocidad inicial del proyectil y el angulo de disparo del proyectil con respecto a la horizontal.
A continuación se presenta un diagrama o esquema donde se pueden ver estas variables y se explicaran a la brevedad:
Para poder encontrar el rango que es la máxima distancia horizontal recorrida por el proyectil debemos utilizar la siguiente ecuación:
![x=(v_{o})_{x} *t\\where:\\(v_{o})_{x} = velocidad inicial x-component [m/s]\\t= time [s]](https://tex.z-dn.net/?f=x%3D%28v_%7Bo%7D%29_%7Bx%7D%20%2At%5C%5Cwhere%3A%5C%5C%28v_%7Bo%7D%29_%7Bx%7D%20%3D%20velocidad%20inicial%20%20x-component%20%5Bm%2Fs%5D%5C%5Ct%3D%20time%20%5Bs%5D)
Para poder encontrar el tiempo debemos utilizar la siguiente ecuación:
![y=(v_{y} )_{o}*t-0.5*g*t^{2} \\donde:\\(v_{y} )_{o}= velocidad inicial componente y [m/s]\\g = gravity = 9.81 [m/s^2]\\t = time [s]](https://tex.z-dn.net/?f=y%3D%28v_%7By%7D%20%29_%7Bo%7D%2At-0.5%2Ag%2At%5E%7B2%7D%20%20%5C%5Cdonde%3A%5C%5C%28v_%7By%7D%20%29_%7Bo%7D%3D%20velocidad%20inicial%20componente%20y%20%5Bm%2Fs%5D%5C%5Cg%20%3D%20gravity%20%3D%209.81%20%5Bm%2Fs%5E2%5D%5C%5Ct%20%3D%20time%20%5Bs%5D)
En la anterior ecuación, igualamos y = 0, ya que cuando el proyectil cae al suelo la distancia vertical es cero. De esta manera podemos encontrar el tiempo t, ya que conocemos la velocidad inicial del proyectil en la componente y.
Seguidamente reemplazamos t en la primera ecuacion y encontramos la distancia x o el rango.

Potential energy will be 
Explanation:
We have given the height of the basin is h = 6 m
Area of the basin 
Volume 
Density 
We know that mass is given by 
We know that potential energy is given by 
<h2>
Answer: its density will decrease</h2>
By increasing the temperature of the iron sphere, its volume will increase (due to the material of which it is composed), this is a phenomenon known as<em> thermal dilation</em>. However, the mass of the sphere will remain the same.
On the other hand, density 
is a characteristic property of substances and materials and is defined as the relationship between the mass 
and volume 
of a specific substance or material, as shown below:
This means <u>density is inversely proportional to volume</u>. Therefore, increasing the temperature of the iron sphere, its volume will be increased and <em><u>its density will be decreased</u></em>.
The Electric field is zero at a distance 2.492 cm from the origin.
Let A be point where the charge 
C is placed which is the origin.
Let B be the point where the charge 
C is placed. Given that B is at a distance 1 cm from the origin.
Both the charges are positive. But charge at origin is greater than that of B. So we can conclude that the point on the x-axis where the electric field = 0 is after B on x - axis.
i.e., at distance 'x' from B.
Using Coulomb's law, 
,
= 
k is the Coulomb's law constant.
On substituting the values into the above equation, we get,
Taking square roots on both sides and simplifying and solving for x, we get,
1.67x = 1+x
Therefore, x = 1.492 cm
Hence the electric field is zero at a distance 1+1.492 = 2.492 cm from the origin.
