I think 1 is x-rays and 2 is ultraviolet light.. I'm not that sure
The time of motion of the ball from the vertical height is independent of the horizontal velocity.
Horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.
The time of motion of ball dropped from a vertical height is calculated as follows;
where;
- <em>h </em><em>is the vertical height</em>
- <em>t </em><em>is the </em><em>time </em><em>of motion</em>
- <em>g </em><em>is acceleration due to gravity</em>
- <em />
<em> is the initial </em><em>vertical velocity</em>
From the equation above, we can conclude that time of motion of the ball from the vertical height is independent of the horizontal velocity.
If there is variation in drop time, it could be as a result of applied force when the ball is dropped. This applied force influences the initial velocity which in turn alters the drop time.
Generally, horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.

Answer:
T = 530 N
, t = 12.65 s
Explanation:
This is an exercise on Newton's second law,
T - W = m a
where T is the tension of the cable, W the weight and the steel of the box
T = W + ma
the weight of a body is
W = m g
Let's replace
T = m g + ma
T = m (g + a)
let's calculate
T = 50 (9.8 + 0.8)
T = 530 N
To calculate the time we use
y = v₀t + ½ a t²
since the box starts from rest on the sole its initial velocity is zero
y = ½ a t2
t = √ 2y / a
let's calculate
t = √ (2 10 / 0.8)
t = 12.65 s

Este es un ejercicio de la segunda ley de Newton,
T – W = m a
donde T es la tension del cable, W el peso y a la aceracion de la caja
T = W + ma
el pesode un cuerpo es
W = m g
Substituyamos
T = m g + ma
T = m ( g +a)
calculemos
T = 50 ( 9,8 + 0,8)
T = 530 N
Para calcular el tiempo usamos
y = v₀t + ½ a t²
como la caja parte del reposo en el suela su velocidad inicial es cero
y= ½ a t²
t= √ 2y/a
calculemos
t = √ (2 10/0,8)
t = 12,65 s
