Answer:
An image formed when the light rays converge at a particular point after refraction and reflection is known as a real image. An image formed when rays appear to meet a particular point after the reflection from the mirror is known as a virtual image. hopes this helps.
Explanation:
D. March because it is just below the 1 million marker on the graph and it is the only one that low.
Answer:
The answer is 3.33m
Explanation:
The acceleration "a" is constant.
Acceleration is the variation of velocity over time,
.
solving the last equation
,
where
because the airplane starts from rest.
Once again, velocity is the variation of distance over time.

then

where
if we consider the end of the runway as the initial point (this step is for simplicity but you can let it expressed, it's going to cancel anyway).
If
at
, then

and the final expression for the distance is
.
If t = 2s, x = 4.44 m. Which means thad the additional distance is

Answer:
1. 98 N
2. 51.0 m
Explanation:
masa 25 kg
velocidad 20 m/s
coeficiente de rozamiento .4
<u>Fuerza de rozamiento:</u>
mu * N, where mu = coeficiente de rozamiento, N = fuerza normal
Calcula N:
F = ma = 25 * -9.8 = -245 N
F rozamiento = mu * N = .4 * -245 = -98 N
<u>Espacio que recorrerá:</u>
F rozamiento = ma
-98 = 25a
a = -3.92 de-aceleración de la fuerza
vf = 0 m/s
vf = at + vi
0 = -3.92t + 20
t = 5.10 seg
x = 1/2 at^2 + vi*t
= 1/2 * -3.92 * 5.10^2 + 20*5.10
= 51.0 m
Mechanical energy is the answer
