The answer is 3.02 x 10^-5
Answer:E = hc/? = 4.41 x 10-19 J
Energy absorbed by each atom :
E (atom) = 2.205 x 10-19 J
Now Bond Energy of each molecule (B) = 3.98 x J
So, for each atom 1.99 x 10-19 J
So now
KE of each atom = E(atom) - B (atom)
= 2.15 x 10-19 J
Answer: 1 inclined plane and box mover trolley
2 screw and drill
3 The axle, or rod and wheels
4 slides, ramps, and hills.
5 yes because they help the ball move quicker
6 i am not sure about this one)
Explanation:i do not know i am guessing
Force is a physical quantity. Thus it makes a reasonable sense to say that it has some units. electric force has a unit of newton too. attraction occurs because there is conservation of charges. thus b is answer
The centrifugal force working against the car would be the entire car's weight, so the centripetal force that is supplied to the car must be the car's tires traction, aka the friction of the car's tires and the surface.
