Answer:
c
Explanation:
It light wave will travel at speed of light and go faster in its wavelength
The formula we need to use is displacement.
, where xf is final position and xi is initial position.
We report the final position of 5 and the displacement of 2 so the formula is now:
.
So the initial position of truck A is 3.
Hope this helps.

The correct answer is
<span>A. Liquid water could exist there.
In fact, liquid water is fundamental for life. So, one of the conditions to define the habitable zone around a star is that the temperature allows the presence of liquid water.</span>
Based on the data provided, the impulse of the floor on the ball is 59.4 Ns.
<h3>What is the impulse of the floor on the ball?</h3>
Using the equation of motion to determine the velocity at the end of the fall
Where v is velocity at the end of fall
u is initial velocity = 0
g is acceleration due to gravity = 9.81 m/s^2
h is height = 20
- Taking downward velocity as negative and up as positive
v^2 = 0 + 2 (9.81)(20)
v^2 = 392.4
v = - 19.8 m/s
The velocity, v after bouncing is calculated also:
u = 0
g = 9.81 m/s^2
h = 5.0 m
v^2 = 0 + 2(9.81)(5)
v^2 = 98.1
v = 9.904 m/s
- Impulse = change in momentum
- Impulse = m(v- u)
Impulse = 2.0 × (9.9 -(-19.8)
Impulse = 59.4 Ns
Therefore, the impulse of the floor on the ball is 59.4 Ns.

There are four (4) kinematic equations, which relate to displacement, D, velocity, v, time, t, and acceleration, a. Kinematic Equations Formula Questions
v=v0+at. v = v 0 + at.
d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.
d=v0t+(at22)
v2=v20+2ad.
