Answer:
5500000 millimeters
Explanation:
1 kilometre= 1000 meter
5.5 km=5.5 * 1000
=5500
Now,
1 metre = 1000 millimetres
5500 metre=1000*5500
=5500000 mm
Answer:
Data:-vi=om/s (b/c as in question penny is dropped from building means before coming to ground its initial state or velocity was considered as zero ) now distance or height h=380m and now we have to find the final velocity vf=? and the time t=?
Explanation:
So applying second eq of motion s=vit+1/2×gt² (here we have taken a gravity b/c when ever body is in vertical position then acceleration due to gravity is applied ) s=0×t+1/2×gt² , s=0+1/2×9.8×t² ,380=4.9t² we have to find t so 4.9t²=380 , t²=380÷4.9 , t²=77.55 now sq root on b/s

so t=8.806s and now apply 1st eq o²f motion to find out vf so vf=vi+gt , vf=0+9.8×8.806 ,vf=86.298 and if you want to verify that either this is answer is correct or not so put the value of t in second eq of motion and if you got distance same as give in the question so your value of t is considered as correct likewise s=vit+1/2gt² , s=0+1/2×9.8(8.806)²,s=4.9×77.55 ,s=380m (proved) I hope it would be helpfull
Answer:
1780
Explanation:
move decimal point to the right 3 times.
To solve this problem we will use the given expression and derive it in order to find the algebraic expressions of velocity and position. These equations will be similar to those already known in the cinematic movement but will be subject to the previously given function. We start deriving the equation for velocity


Integrate acceleration equation



At 
Replacing,

Therefore the value of the first Constant is

The expression can be escribed as,

Calculate the velocity after 6s,



Now using the same expression we can derive the equation for distance




At t=0, x=0

Therefore the value of the second constant is


Calculate the distance traveled after 11 s
At 


Answer:
Particles of electromagnetic radiation exhibit wave behavior
Electromagnetic radiation includes visible light
The specific amount of energy a particular photon possesses is called a quantum
Explanation:
Electromagnetic waves propagate through space perpendicularly to a oscillating magnetic and electric field producing it. Both of these fields oscillates perpendicular to one another, and to the direction of propagation of the wave.
Electromagnetic waves exhibit both wave and particle light behaviors, this phenomenon is known as the wave-particle duality.
Visible light is part of the broad spectrum of waves in the electromagnetic wave spectrum. And each particle of an electromagnetic wave is known as a photon, and they carry energy in discrete amounts called quantum.
