1:-A convex lens is a lens that converges rays of light that are travelling parallel to its principal axis.
Assuming the acceleration is constant, then we can use the derived equations for rectilinear motion. The equation is written below:
2ax = v²- v₀²
where
a is the acceleration
x is the distance
v is the final velocity
v₀ is the initial velocity
Since the car came to a stop, v = 0. Substituting the values,
2a(0.80 m) =0² - [(95 km/h)(1000 m/1 km)(1 h/3600 s)]²
Solving for a,
a = -435.23 m/s²
The sign is negative because it is decelerating.
A = -9.8
v = -9.8t -8
s = -4.9 t2 -8t +25
So… -5t^2 -8t + 25 =0, we’ll rearrange to 5t^2 + 8t - 25. We get two roots, one is positive and is 1.59 seconds
V = -9.8(1.59) - 8 = -23.6
So… it takes 1.59 seconds to hit the ground at -23.6 m/s.
The water tank waves are transverse waves while the sound waves are longitudinal waves.
<h3>What is a wave?</h3>
A wave is a disturbance along a medium which transfers energy. We know that the water tank waves are transverse waves while the sound waves are longitudinal waves.
The difference between the two is that in the water waves, the direction of the wave motion is perpendicular to the disturbance while in the sound waves, the the direction of the wave motion is parallel to the disturbance.
