Answer:
Refraction is the slowing down of light waves as they pass into a different medium and speeding as they pass out.
hope it helps. plz mark me as brainliest.
Answer and Explanation:
Ferritic and Austenitic stainless steels are not heat treatable since the term "heat treatable" means that Martensite may be made to form in a relatively easy way after it has quenched the Austenite from an increased temperature.
You can compare the velocity of the car, 60 mph, with the velocity that a mass would acquire when falls from certain height.
First, convert 60 mph to m/s:
60 miles/h * 1.60 km/mile * 1000 m/km * 1h/3600s = 26.67 m/s
Second, calculate from what height a body in free fall reachs 26.67 m/s velocity when hits the floor.
free fall => Vf^2 = 2g*H => H = Vf^2 / (2g)
H = (26.67m/s)^2 / (2*9.8 m/s) = 36.2 m
If you consider that the height between the floors of a building is approximately 3.6 m, you get 36.2 m / 3.6 m/floor = 10 floors.
Then, you conclude that the force of impact is the same as driving you vehicle off a 10 story building.
Answer:
Explanation:
We have given that mass of electron 
It is given that initial velocity u=0 m/sec
Final velocity v = 
Distance S = 2.2 cm = 0.022 m
According to third law of motion 
Accelerating force F is given by F = ma
So accelerating force 
A unit of measurement is a define magnitude
