Answer:
Finley, Xander and Max
Explanation:
v = Final velocity
t = Time
u = Initial velocity = 0
a = Acceleration
From kinematic equations we get
[tex]v=u+at\\\Rightarrow a=\dfrac{v-u}{t}=\dfrac{v-0}{t}\\\Rightarrow a=\dfrac{v}{t}[/tex]
Xander
v = 4.5 m/s, t = 3.5 s
[tex]a=\dfrac{4.5}{3.5}\\\Rightarrow a=1.29\ \text{m/s}^2[/tex]
Finley
v = 3.6 m/s, t = 4.2 s
[tex]a=\dfrac{3.6}{4.2}\\\Rightarrow a=0.86\ \text{m/s}^2[/tex]
Max
v = 7.3 m/s, t = 1.2 s
[tex]a=\dfrac{7.3}{1.2}\\\Rightarrow a=6.083\ \text{m/s}^2[/tex]
The required list is Finley, Xander and Max.

Explanation:
A boom is to be dropped from moving helicopter on the ground. Explain how can it hut the target ?
Answer:
A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity. Therefore, the bomb should be dropped from farther distance equal to the horizontal range before the helicopter reaches above the target.

What is the correct reason for blinking / flickering of stars? Explain it.
A) The blasts in the stars.
B) Absorption of star light by the atmosphere.
C) Motion of the stars.
D) Changing refractive index of gases in the atmosphere.
plz suggest me a answer which can give me 3 marks
Answer:
d. changing refractive index of gases in the atmosphere
Explanation:
light from a star passes through the atmosphere to reach our eyes. however, the layers of gases in the atmosphere are in constant motion, so the light gets bent and appears to be flickering.
i hope this helps! :D
Why are the oceans movements along the What do ocean waves have in common with the sound and light
Answer:
Oceanic currents an waves are in motion due to energy of wind.
Explanation:
When the wind blows across the ocean water ts creates a pull and push effect. It pulls the top layers of water and creates a frictional drag force that leads to the movement of water molecules and appears that the surface is moving. The movement can be seen in the form of surface oceanic currents and waves that are found through the entire globe. The ocean waves and currents carry with them the energy from one place to another.
