The color green is the the color of light in the visible spectrum which appears the brightest, but with proper illumination, the color green-yellow appears to be the brightest, with the human eye having the maximum sensitivity of 555nn
Answer:
Position at t= 4 seconds is 144 m
Explanation:
It is given that acceleration, a = 18 t, where t is the time.
We know that Velocity, 
Substituting value of a,
Velocity, 
We know that at t = 0, v = -12 m/s
So, 
So velocity, 
We also know that displacement, 
Substituting value of v,
Displacement, 
We know that at t = 0, particle is at origin, x =0.
So, 
Displacement, 
At t = 4 seconds

Position at t= 4 seconds is 144 m
Answer:
The specific heat of aluminum is greater.
Explanation:
It lost the most heat.
The system is located in the HairyFunyon aka near the floor
Answer:
44.64 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²


<u>Time taken to reach 1180 m is 11.29 seconds</u>

<u>Time the rocket will keep going up after the engines shut off is 13.06 seconds.</u>

The distance the rocket will keep going up after the engines shut off is 836.05 m
Total distance traveled by the rocket in the upward direction is 1180+836.05 = 2016.05 m
The rocket will fall from this height

<u>Time taken by the rocket to fall from maximum height is 20.29 seconds</u>
Time the rocket will stay in the air is 11.29+13.06+20.29 = 44.64 seconds
