It Refers to the emission of electrons from a metal when light shines on metal. Example: static electricity
A train takes ms eaddy 200 miles north and 150 miles south. The total trip took 3.5 hours what was the average velocity of the train in MPG?
A 55kg female bungee jumper fastens one end of the cord (made of elastic material) to her ankle and the other end to a bridge. Then she jumps off the bridge. As the cord is stretching it exerts an elastic force directed up on her. Calculate her acceleration at the instant the chord exerts an elastic force of 825N [up] on her.
Two diverging light rays, originating from the same point, have an angle of 5° between them. After the rays reflect from a plane mirror, what is the angle between them? Construct one possible ray diagram that supports your answer.
An object with mass 60 kg moved in outer space. When it was at location < 13, -19, -3 > its speed was 3.5 m/s. A single constant force < 220, 320, -120 > N acted on the object while the object moved from location < 13, -19, -3 > m to location < 18, -11, -8 > m. Then a different single constant force < 150, 230, 220 > N acted on the object while the object moved from location < 18, -11, -8 > m to location < 22, -17, -3 > m. What is the speed of the object at this final location? final speed = m/s
A graph depicts force versus position. What represents the work done by the force over the given displacement? A. The work done is equal to the product of the maximum force times the maximum position. B. The work done is equal to the area under the curve. C. Work cannot be determined from this type of graph. D. The work done is equal to length of the curve. E. The work done is equal to the slope of the curve.
a subway train starts from rest at a station and accelerates uniformly at 1.8m/s^2 for 15 sec. then it runs at a constant speed for the next 35 sec. before decelerating at 2.0m/s^2 until it comes to rest at the next station. FIND THE DISTANCE between the stations and the AVERAGE SPEED of the train. (please show step by step and the formula that is used. Thank you!)
