g A block of mass 0.42 kilogram is initially at rest at the top of a frictionless ramp that has a surface length of 1.3 meters and is inclined by 12 degrees above horizontal. The block slides down and impacts a spring with spring constant k, causing the spring to compress by 0.41 meters when the block comes to a rest. What is the value of the spring constant in units of Newton/meter

It is really hard for me right know

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
