Answer:
C: Smoke rises out of very hot substances
Explanation:
Edge
Answer: K-core , 1s orbital
Explanation: Electron of Hydrogen atom has lowest energy
when it is in K core (1s-orbital)
This is an <em>inelastic </em>collision. The equation for an inelastic collision is: 
(110)(6) + (150)(-4) = (110 + 150)(vf)
660 - 600 = 260vf
60 = 260vf
vf = 0.2308 m/s
They will travel in the positive direction, right, and their combined velocity will be 0.2308 m/s.
Hope this helps!! :)
Answer:
Δv = 12 m/s, but we are not given the direction, so there are really an infinite number of potential solutions.
Maximum initial speed is 40.6 m/s
Minimum initial speed is 16.6 m/s
Explanation:
Assume this is a NET impulse so we can ignore friction.
An impulse results in a change of momentum
The impulse applied was
p = Ft = 1400(6.0) = 8400 N•s
p = mΔv
Δv = 8400 / 700 = 12 m/s
If the impulse was applied in the direction the car was already moving, the initial velocity was
vi = 28.6 - 12 = 16.6 m/s
if the impulse was applied in the direction opposite of the original velocity, the initial velocity was
vi = 28.6 + 12 = 40.6 m/s
Other angles of Net force would result in various initial velocities.
Answer:
The maximun distance is 
Explanation:
From the question we are told that
The wavelength are 

The distance of seperation of the two slit is 
The distance from the screen is 
Generally the distance of the bright fringe to the center of the screen is mathematically represented as

Where m is the order of the fringe
For the first wavelength we have



For the second wavelength we have


----(2)
From the question we are told that the two sides coincides with one another so



Hence for this equation to be solved

and 
Substituting this into the equation

Hence
