The father is in the Navy and is away for long periods of time. While he is away, is it almost like he doesn't exist; he is in "a shadow world". He is real only when out of the sea "from below the waterline". His periodic retu…

The photon is massless, but it does have energy according to Plank's Law E=h*f, where f=frequency of the light, and h = Plank's constant. According to relativity theory that energy will act like mass in a gravitaional field and in conservation of m…

If there is enough light to get a good picture without motion blur, then I believe natural light is always best. Ordinary camera flash will leave deep harsh shadows, and objects closer to the camera will be more exposed than distant ones. Flash c…

You can get some of the answer from inspection. For example, plug x = -1 into the equation, and the (x + 1) terms go to zero, making the whole equation zero. So x = -1 is one solution. Exclude this x value, and divide through by (x + 1)^2 to get …

You can also get the distance from energy consideration: Friction force = ¨µ*m*g*cosθ Sliding force = m*g*sinθ At constant velocity these are equal so µ*m*g*cosθ = m*g*sinθ and µ = tanθ The initial energy is 0.5*m*vB² this must equal…

Work done by the force = increase in KE plus friction energy loss increase in KE = 5.6 - 4 = 1.6 J friction energy loss = Friction force x distance moved = 1.2N*0.5m = 0.6 J work done = 2.2 J Work done on the block by friction = -0.6 J
