Answer:
Sabemos por definición que la fuerza es lo que es capaz de producir cambios o deformaciones en un cuerpo y a esto se denomina efecto estático y cuando la alteración ejerce movimiento o reposo se denomina efecto dinámico, con esta base resolvemos que:
-estirar un muelle: efecto estatico
- devolver una volea: efecto dinámico
- aplastar la plastilina: efecto estático
- empujar el carro del supermercado: efecto dinámico
- inflar un globo: efecto estático
Answer:
One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air.

Explanation:
Answer:
-969.06
-286.74
698.7
-115.6, 12.9
-139.9, 12.9
Explanation:
Given that
Speed v, wrt y = -24.3 m/s
Speed v, wrt x = 12.9 m/s
time t, = 11.8 s
a
Using the formula
H(t) = ut - 1/2gt², where u = v wrt y
H(t) = -24.3 * 11.8 - 1/2 * 9.8 * 11.8²
H(t) = -286.74 - 682.28
H(t) = -969.06 m
b
H = ut, where u = v wrt y
H = -24.3 * 11.8
H = -286.74 m
H(1) = -969.06 - -286.74 = -682 m
c
Horizontal displacement, x = vt. Where v = v wrt x
x = 12.9 * 11.8
x = 152.22 m
d = √(H1² + x²)
d = √682² + 152²
d = 465124 + 23104
d = √488228
d = 698.7 m
d
Vertical component =
-gt - 0 =
-9.8 * 11.8 = -115.6
Horizontal component =
v wrt x - 0
12.9 - 0 = 12.9
e
Vertical component =
-gt - v wrt y =
-9.8 * 11.8 - 24.3 = -139.9
Horizontal component =
v wrt x - 0 =
12.9 - 0 = 0
